5 CPS-361 (C10) Cement Pumping Skid Operating Manual / QHSE 5
2 QHSE
All Schlumberger employees must be familiar with the relevant safety regulations
and precautions described in the Safety and Loss Prevention Manual (SLPM)
because of the many hazards involved in the oilfield industry.
Anyone who feels an operation is unsafe has the right and duty to stop the
operation.
Standard 21
Be sure that you know the relevant contents of the material data safety sheet
(MSDS) regarding required personal protective equipment (PPE) and handling
procedures when handling chemicals.
PPE is important, but does not in itself prevent accidents; that is the responsibility
of the individual, you. It is vital that your knowledge of Standards 5, 9, and 11
be kept up-to-date and put into practice at all times.
You should also be familiar with the following:

• General Section 1 – Schlumberger HSE Management System (HSEMS)
• General Section 7 – HSE Reporting Requirements
• Standard 1 – General HSE Standards
• Standard 4 – General Facility and Workshop
• Standard 7 – Utility Trailers
• Standard 8 – Motor Vehicle Operations
• Standard 17 – Storage and Handling of Oxidizers
• Standard 18 – Chemical Hazard Communication (HAZCOM) and Material
Handling
2.1 Personnel Safety

Be sure that all relevant procedures and standards are followed at all times.
Make certain that PPE is always worn around the unit.
Private
It is important to remember the dangers of the high pressure and heat that this
unit generates. Avoid the area around the fluid end and the discharge lines
during pumping as much as possible. The exhaust lines and parts of the engine
become extremely hot during operation and can cause severe burns.
Be aware of all moving parts on the unit while it is running. All non-essential
personnel should stay away from the unit during operation. If there is a need
to climb up on the unit, exercise care, especially if it is necessary to climb up to
the radiator fills.
2.2 Equipment Safety

Equipment should be maintained according to the regular standard equipment
maintenance (STEM) system. Complete the following Schlumberger Preventive

Maintenance check:
2.2.1 Pre-Trip Inspection

Check the following items on the skid equipment:
• Fuel level
• Engine oil level
• Jacket water and aftercooler water coolant level
• Transmission oil level
• Power-end oil level
• Packing lube reservoir oil level
If fuel will be added before leaving the district, see Standard 8, 10.5 in the SLPM.
Additional requirements must be met when pumping carbon dioxide (CO2) or
Nitrogen (N2).
• When pumping C02: Safety Standard 9, as specified in Section VII of the
SLPM, must be performed in addition to the requirements of Safety Standard
5.
• When pumping N2: Safety Standard 11, as specified in Section VII of the
SLPM, must be performed in addition to the requirements of Safety Standard
5.
2.2.2 Pre-Job Checklist

Always be alert for emergency situations. Failure to spot an emergency can
result in equipment damage and/or personal injury.
Private
You are responsible for constantly monitoring the control panel and the work
location for any and all hazards. All equipment must be spotted and hooked up
to the wellhead in accordance with the service supervisor’s instructions and
the SLPM standards.
Ensure that all guards are in place around moving parts and that everyone is at a
safe distance before starting the unit.
2.2.2.1 Fluid-End Lubrication

The fluid-end lubrication system consists of a pressurized oil tank. The air
pressure is bled off whenever the pump brake is ON.
Never strike the tank. Always be sure that there is no pressure in the tank before
opening the top cap.
2.2.2.2 Engine
Before starting the engine, make sure that all personnel are clear of the engine
area.
If working on the engine while it is shut down, place a lockout tag on the start
switch to ensure that no one can start the engine without your knowledge.
A flash fire may result if the crank case covers are removed after an emergency
shutdown before 15 minutes have passed.
The electronic unit injector system uses 90-110 V. Touching the harness
connector for the fuel injector while the engine is operating can result in an
electrical shock.
Be careful when touching any part of an engine during operation, as some parts
can be extremely hot.
The coolants are very hot during and immediately after the engine is run. The
coolant will also be under pressure. Exercise extreme caution if the caps need to
be removed while the engine is still warm.
Leaking fuel, most lubricants, and some coolant mixtures are flammable. A fire
can result if any of these fluids leak on to hot surfaces or electrical components.
Private
2.2.2.3 Transmission
If the pump stalls out, do not operate the engine for more than 30 seconds at full
throttle with the transmission in gear. Prolonged operation of this type will cause
excessively high transmission temperatures that will damage the transmission.
In cold weather, it is important to take time to warm up the transmission oil before
engaging the transmission. Oil temperatures need to conform to the following
guidelines:
• Only at >20ºF can the transmission be used in all gears
• If –9<T>20ºF, only run the transmission in neutral or 1st gear.
• If T<-10ºF, run in neutral only.
2.2.2.4 Emergency Kill Switch

The emergency kill switch immediately shuts off the fuel and air supply to
the deck engine, resulting in system shutdown. The switch is located on the
operator’s remote-control console. Two manual emergency shut-down switches
are located on the top of each side of the engine. The red knob must be pressed
in on both sides to completely shut down the engine.
2.3 Environmental
Any chemical spill must be contained and cleaned up according to local
procedures. Any spill must also be reported according to local procedures.
Please see the following standards for further information:

• SLPM Standard 17 – Storage and Handling of Oxidizers
• SLPM Standard 18 – Chemical Hazard Communication (HAZCOM) and
Material Handling
When disposing of oils, filters, and batteries, ensure that these items are
disposed of in an environmentally acceptable way and in accordance with local
regulations.
Private
2.4 Transportation
2.4.1 Pre-Trip Inspection

Before leaving the yard, check all pumping equipment visually for the following
problems to ensure equipment safety and road safety during travel:
• Oil leaks
• Coolant leaks
• Radiator core
• Damaged hoses
• Loose or damaged components

• Inadequately secured loose equipment and remote cables on deck
2.4.2 Travel to Location

You may travel to the job location after you have completed the requirements
outlined in Section 2.2.1: Pre-Trip Inspection. You must comply with the
appropriate Standard of the SLPM
2.4.3 At the Location

Safety Standard 5 as specified in the SLPM is in effect at this time.
Private
10 CPS-361 (C10) Cement Pumping Skid Operating Manual / Specifications 10
3 Specifications
3.1 Skid Frame

The CPS-361 is built on a multi-section frame divided into four sections. All
four sections are approximately equal in weight and size. The interlocking
design of the four sections requires only 10 bolts to secure the frame itself. The
displacement tank comprises the fifth section.
The complete unit and all apppendages are secured to the two main frame rails,
which include supports for the:
• Engines
• Pumps
• Displacement tank
• Decking
This method of construction allows easy access for servicing the unit.
The skid frame design minimizes locations for water traps by using structural
tubing that has been seal-welded to form hollow members.
Potential Severity: Light

Potential Loss: Assets
Hazard Category: Machinery equipment hand tools
Do not drill or puncture the members.
The offshore paint system used to coat the skid is essential to maintain its
protection and appearance. The unit should be kept as clean and free of oil as
possible to protect this system. Continual touching- up of the paint keeps the
skid free from corrosion.
As is any piece of machinery, the skid is subject to a series of vibrational forces.

This leads to periodic loosening of the fastening devices, such as bolts and
machine screws. Occasional retightening of the fasteners is necessary for safe
and proper operation of the unit.

Figure 3-1: CPS-361 Control Console
1. Slurry Recirculation Valve

This valve allows for quick shutoff of slurry that is being recirculated to the
Slurry Chief mixer.
Private
2. Quick Cement Shutoff

This valve controls the cement surge tank discharge valve. The air bulkhead
connection is located at the rear of the skid on the displacement tank support
leg.
3. Front Engine – Pressurizer Pump PTO Engage/Disengage
The air switch in the UP position engages the pressurizer centrifugal pump.
The switch in the DOWN position disengages the pump.
Note
The engine must be shut down before engaging the PTO.
4. Front Engine – Injection Pump PTO Engage/Disengage

The air switch in the UP position engages the injection centrifugal pump. The
switch in the DOWN position disengages the pump.
Note
5. Quick Water Shut off – Front Transmission

The air switch in the UP position opens the injection centrifugal pump suction
and discharge valve. The switch in the DOWN position closes the pump
suction and discharge valve.
6. Front Engine Throttle
The front engine throttle control knob controls the speed of the engine.
Turning the knob to the full counter-clockwise position places the engine at
idle. The full clockwise position is rated speed (2,100 rpm). The throttle
control knob is connected to a potentiometer that varies a resistance and
alters the voltage signal to the PWM converter. The converter provides the
engine with a pulse-width modulated throttle signal.
The throttle control knob has an additional feature. In the event of an
over-pressure condition, the throttle signal is interrupted and the engine
drops to idle speed. The throttle control knob becomes inactive until the
over-pressure condition is reset. To reset an over-pressure condition, check
to see that the pressure reading on the digital gauge is below the trip
pressure, then rotate the throttle control knob to the full counter-clockwise
(idle) position. This will reset the over-pressure condition, and restore throttle
control to the throttle control knob.
7. Front Engine Run/Kill Switch
Private
The engine run/kill switch enables the engine to run and perform a normal
stop. For the engine to start, the engine run/kill switch needs to be in the
RUN position. The switch in the KILL position shuts off fuel to the engine
and performs a normal stop.
8. Front Transmission Shifter
This pneumatic valve shifts the front transmission into the different gear ratios
during the pumping operation. The five-speed shifter (1 through 5) controls a
pneumatic positioner located on the transmission. Consult the performance
curves in this manual to ensure that the unit is operated within the correct
gear range for the pump rate and discharge pressure requirements.
9. Front Engine Air-Start Push Button
This pneumatic switch activates the engine air-start pilot valve. The air-start
push button should be pushed down to start the engine.

10. Unit Indication LEDs – Front Power System
The Unit Indication LEDs give the operator a visual indication of the CPS-361
Cementer Skid's status. The LEDs indicate the following conditions:
• Converter lock-up – appears amber in color when transmission lockup
is achieved. This normally occurs at engine speeds in excess of 1,450
rpm. Gear selection and throttle position should always ensure lock-up
condition.
• Check unit – illuminates when a skid parameter is out of range or the
engine ADEM controller experiences a fault. The operator should check
the gauges for an out-of-range parameter. ECAP or ET Caterpillar
software can be used by a trained technician to check registered engine
controller faults.
• Engine diagnostic codes – displays engine flash codes. The flash codes
are two-digit representations of a fault diagnostic code. The LED will
blink for the first digit of the flash code, pause 5 seconds, and then
blink for the second digit. Flash codes should only be interpreted as a
general idea of a problem, and not used for troubleshooting. Caterpillar
engine documentation SENR1073 should be used for troubleshooting
procedures.
11. Lamp Test Switch

The lamp test switch verifies the operation of the Unit Indication LEDs. This
momentary switch in the UP position illuminates all six LEDs. If an LED is not
working, check the termination at the base of the lamp and its corresponding
terminal block inside the operations console.
12. Switch Gauges – Front Power System
Private
The switch gauges monitor vital system parameters. The switch gauges not
only provide a mechanical reading of temperature or pressure, they also have
an internal switch that is activated by either low pressure or high temperature.
Parameters checked are:
• Engine oil pressure
• Engine coolant temperature
• Transmission oil temperature
• Oil pressure
• Lock-up pressure
• Triplex pump lube temperature
• Triplex pump lube pressure
13. Front Engine Tachometer/Hourmeter

The digital tachometer/hourmeter displays front engine speed and total
engine hours. The tachometer system is self-powered and consists of the
display and a magnetic pickup, which are designed to work together to
provide a speed rpm display when the engine speed is above 600 rpm.
To view the engine hours, momentarily press and release the push button
located on the face of the meter. After 20 seconds, the meter returns to
rpm display.
14. Front Pump Martin Decker Digital Gauge
The digital gauge system provides a digital readout of the following:
• Front pump discharge pressure
• Triplex pump rate (bpm)
• Total barrels (bbls) pumped
This gauge has an over- pressure shutdow n that can be set for various
pressures. The shutdow n setting is located in the ALARMHI section of the
graphics module display. The alarm setting is displayed on the face of the
gauge in the pressure display mode, above and right of the bar graph.
The bar graph indicator is a multi- purpose analog indicator used to view the
full range of the ALARMHI setting s. An incremental multiplier is displayed
to the right of the bar graph because the values are limited to three digits.
If (x100) is shown, the lower and upper limits of the bar graph should be
multiplied by 100. An alarm symbol, depicted as a bell, appears when a
programmed alarm set-point has been exceeded.
The setting of the over- pressure condition to reduce the front engine to idle
is also programmed from the digital gauges. See Figure 3-2: Martin Decker
Digital Gauge, to identify the para meters and functions of the gauge.

Figure 3-2: Martin Decker Digital Gauge
The front pump rate display picks up a signal from a proximity switch located
at the rear of the transmission counting the driveline bolts. The signal from
the switch goes to a Martin Decker junction/barrier box located underneath
the control console, and then to the gauges. The rate is displayed in the
barrels per minute (bpm) pumped by the front triplex
Note
The fluid-end type shown on the graphics module screen with in the BPM
section of the digital gauge must correspond to the fluid end on the skid or
the rate reading will be incorrect. The fluid-end type and K-factor s are in
the software of the gauges.
15. Slurry King Remote

The Slurry King remote includes four LED indicators and an auto/manual
toggle button as follows:
• Density OKAY LED – lights up when the density of the slurry is within
0.2% of the desired density setting.
• Alarm Aux. LED – lights up when an alarm condition exists. There are
two conditions that will enable the Alarm Aux. LED. When there is a high
or low alarm, the LED flashes. This allows the operator to adjust and
make corrections to the operation. When there is a HIGH HIGH or LOW
LOW alarm, the LED lights up continuously.
• AUTO LED – lights green when the DCS is in automatic mode. This
indicates that the control software governs the process.
Private
• MAN LED – lights red when the DCS is in manual mode. This means the
operator has control of the process from the cement-metering wheel.
• AUTO/MANUAL toggle button – allows the operator to toggle between
auto and manual mode.
16. Density Display

The Micro-Motion PI420 meter displays the actual density reading of the
cement slurry from the micro-motion sensor. The display uses a 4-20 mA
signal to indicate density.
The scale is 4 mA = 0.0 lbm/gal and 20 mA = 25.0 lbm/gal.
17. Quick Water Shutoff – Rear Transmission
The air switch in the UP position opens the injection centrifugal pump suction
and discharge valve. The switch in the DOWN position closes the pump
suction and discharge valve.
18. Injection Pump PTO Engage/Disengage
The air switch in the UP position engages the injection centrifugal pump. The
switch in the DOWN position disengages the pump.
Note
19. Rear Engine – Pressurizer Pump PTO Engage/Disengage

• The air switch in the UP position engages the pressurizer centrifugal
pump.
• The switch in the DOWN position disengages the pump.
Note
20. Cement Meter Wheel

This hand-operated, hydraulically assisted wheel opens or closes the cement
metering valve.
• Turn valve counter-clockwise to open valve, allowing more dry cement
into the mixer.
• Turn the valve clockwise to close the valve, reducing the amount of dry
cement fed to the mixer and reducing slurry density.
21. Rear Engine Throttle

The rear engine throttle control knob controls the speed of the engine.
Private
Turn the knob to the full counter-clockwise position to place the engine at
idle. The full clockwise position is rated speed (2,100 rpm). The throttle
control knob is connected to a potentiometer that varies resistance and alters
the voltage signal to the PWM converter. The converter provides the engine
with a pulse-width modulated throttle signal.
In the event of an over-pressure condition, the throttle signal is interrupted
and the engine drops to idle speed. The throttle control knob becomes
inactive until the over-pressure condition is reset.
22. Rear Engine Run/Kill Switch
The engine run/kill switch enables the engine to run and perform a normal
stop. For the engine to start, the engine run/kill switch needs to be in the
RUN position. The switch in the KILL position shuts off fuel to the engine
and performs a normal stop.

23. Rear Transmission Shifter
This pneumatic valve shifts the rear transmission into the different gear ratios
during the pumping operation. The five-speed shifter (1 through 5) controls a
pneumatic positioner located on the transmission. Consult the performance
curves in this manual to ensure that the unit is operated within the correct
gear range for the pump rate and discharge pressure requirements.
24. Rear Engine Air-Start Push Button
This pneumatic switch activates the engine air-start pilot valve. The air start
push button should be pushed down to start the engine.
25. Emergency Kill Switch
The emergency kill switch shuts down the engines in the event of an
emergency. To activate this switch, open the red protective cover and move
the switch to the UP position. This pneumatic switch closes the air intake
valve for both engines.
In addition, a pressure switch located inside the operations panel senses the
loss of air pressure when the emergency kill switch is activated, and also
sends an electrical signal to the engines to shut off the fuel.
26. Unit Indication LEDs – Rear Power SystemThe Unit Indication LEDs give
the operator a visual indication of the CPS-361 Cementer Skid status. The
LEDs indicate the following conditions:
• Converter lock-up – appears amber in color when transmission lockup
is achieved. This normally occurs at engine speeds in excess of 1,450
rpm. Gear selection and throttle position should always ensure lock-up
condition.
Private
• Check unit – lights up when a skid parameter is out of range or the

engine ADEM controller experiences a fault. The operator should
check the gauges for an out-of-range parameter. In addition, ECAP or
ET Caterpillar software can be used by a trained technician to check
registered engine controller faults.
• Engine diagnostic codes – displays engine flash codes. The flash codes
are two-digit representations of a fault diagnostic code. The LED will blink
for the first digit of the flash code, pause 5 seconds, and then blink for the
second digit. Flash codes should only be interpreted as a general idea
of a problem, and not used for troubleshooting. See Caterpillar engine
documentation SENR1073 for troubleshooting procedures.
27. Switch Gauges – Rear Power System

The switch gauges monitor vital system parameters. The switch gauges
not only provide a mechanical reading of temperature or pressure, they
also have an internal switch that is activated by either low pressure or high
temperature. The parameters checked are:
• Engine oil pressure
• Transmission oil temperature
• Oil pressure
• Lock-up pressure
• Triplex pump lube temperature
• Triplex pump lube pressure
28. Process Piping Schematic

The engraved process piping on the panel indicates the air-operated process
valves by means of a pneumatic toggle switch. When the air switch is in the
UP position the valve is open, and in the DOWN position the valve is closed.
The engraving also helps the operator follow the process flow of the unit
together with the mixer piping and the surge tank piping.
29. Rear Pump Martin Decker Digital Gauge
The digital gauge system provides a digital readout of:
• Rear pump discharge pressure
• Triplex pump rate (bpm )
• Total barrels (bbls) pumped
Setting of the over- pressure condition to reduce the rear engine to idle is
programmed from the digital gauges. See Figure 3-2: Martin Decker Digital
Gauge, to identify the para meters and functions of the gauge.
30. Rear Engine Tachometer/Hourmeter
Private
The digital tachometer/hourmeter displays rear engine speed and total

engine hours. The tachometer system is self-powered and consists of the
display and a magnetic pickup, which are designed to work together to
provide a speed rpm display when the engine speed is above 600 rpm.
To view the engine hours, momentarily press and release the push button
located on the face of the meter. After 20 seconds, the meter returns to
rpm display.
31. Master Power Switch
The master power switch distributes 24 VDC throughout the skid control
system. This switch must remain in the On position for the unit to operate.
Potential Severity: Serious

Potential Loss: Assets
Hazard Category: Electrical, Machinery equipment hand tools, Pressure
The purge system must operate for 7 minutes prior to placing the Master
Power Switch in the On position.
3.3 Hydraulic System

The CPS-361 pumper uses a "power-steering" type of hydraulic control system
to provide metering valve action for the various mixers.
The system consists of an engine-driven vane-type pump on the front engine,

with a 10-quart size remote-mounted reservoir and a hand wheel control valve
(cement- metering wheel) located on the control console.
The cement-metering wheel rotates clockwise to close, and counter-clockwise to

open the Slurry Chief knife gate. The front engine must be running to provide
power to the hand wheel.
3.4 Pneumatic System

The CPS-361 uses high pressure air (150 psi max.) to control the unit during
pumping operations. The unit has the following components:
• Air-controlled engine starters
• Transmission shifters
• Valve actuators
• Pressure packing lube reservoir
Private
The CPS-361 depends on an external compressed air supply to maintain

pressure in its 35-gallon reservoir. The minimum acceptable air supply to the
reservoir is 30 cfm.
The air supply to the main control valve passes through a Parker Finite
Coalescing filter to remove small particles and excess moisture. The main
control valve, located on the rear of the engine covers, controls the air supply
to the console and the air starters. From the main control valve, the air supply
divides into two lines:
• One supplying the air starters
• One supplying the console
Prior to entering the control console, the air is conditioned by passing through
another dryer to remove damaging moisture. This air supply then splits, one line
going to an air purge control system, the other line going through a lubricator,
and then to the control console manifold. See 3.4: Pneumatic System.
3.5 Electrical System

The electrical system is explained in detail in the Caterpillar CPS-361 Offshore
Cementer Control System Operations Manual.
3.6 Non-Radioactive Densitometer (NDR)

The CPS-361 comes equipped with the following:
• Micro-Motion DS300 Sensor mounted on the 6-bbl mix tub
• RFT-9739 Transmitter mounted to the right of the Azonix Amdec 100
The transmitter power supply is 12 to 30 VDC, and the outputs used are two
4-20 mA analog signals for the density.
• The first analog signal, PV (Primary Variable), goes to the Amdec 100.
• The second analog signal, SV (Secondary Variable), goes to the Micro-Motion
PI420 Remote Density Display located on the control console.
The transmitter is powered with 24 VDC from the Amdec 100 AC to DC power
supply.

3.7 Mixer
The Slurry Chief mixer jets slurry into a mix tub connected to an RA56 centrifugal
pump. This pump pressurizes the suction of the triplex and also recirculates
slurry back to the Slurry Chief mix bowl for added mixing of the incoming
dry cement. The Slurry Chief mixer may be gravity-fed from a surge tank or
pneumatically fed from a pressurized tank.
When using the Slurry Chief mixer, the operator must remember a few rules of
good operation to avoid potential problems that might interfere with the mixer’s
performance.
Note
Close and lock the ball valve in position on the Mark III SLURRY CHIEF mixer
hydraulic supply line whenever there is ongoing maintenance or inspection for
the knife gate.
Users of MARK III SLURRY CHIEF MIXER are required to check if a ball valve
is installed on the hydraulic line to the mixer. If not, it is required to install one.
See Appendix A.2: MB 1426-B: Install Ball Valve on MARK III SLURRY CHIEF
MIXER Hydraulic Supply Line, for more instructions.
3.8 Pumps
3.8.1 Dowell RA56

The RA56 centrifugal pump pressurizes fluids for the displacement tank and
mixers. This pump also recirculates slurry for the Slurry Chief mixer. The 5x6
is used to provide a positive head pressure at the triplex pumps to allow more
efficient pumping of the high-viscosity fluids.
The RA56 centrifugal pump contains two outboard bearings to support the shaft.
These bearings must be lubricated regularly through grease zerks.
Private
Note
One of the grease zerks must be a vent type of fitting; if not, remove one of
the zerks before pumping the grease to prevent extruding the seals. The shaft
seals are lubricated by the pressurized packing lube system. The seals are only
lubricated when the PTO driving the RA56 is engaged.
3.8.2 Dowell RA45 Centrifugal Pump

The RA45 centrifugal pump supplies mix water to the jet manifold. The jet
manifold then distributes the mix water to the Slurry Chief mixer jet and to the
mixing tub via the Slurry Chief discharge elbow. The valves on the jet manifold
are named as follows:

• Mix Water Valve – goes to the jet
• Thin-Up Valve – goes to the discharge elbow
The RA45 centrifugal pump contains two outboard bearings to support the shaft.
These bearings must be lubricated regularly through grease zerks.
Note
One of the grease zerks must be a vent type of fitting; if not, remove one of
the zerks before pumping the grease to prevent extruding the seals. The shaft
seals are lubricated by the pressurized packing lube system. The seals are only
lubricated when the PTO driving the RA45 is engaged.

4.1 Treating Equipment

The CPS-361 can be used as an offshore unit. The treating equipment used is
the same, but the hookup and unit placement vary greatly. The operator must
follow the guidelines set out by the local district. The treating equipment should
be kept clean and well lubricated, regardless of where it is used. Schlumberger
Safety and Loss Prevention Standards 5-9-11 provide guidelines to proper unit
hookup, as well as location safety tips.

5 Unit Operation
5.1 Taking on Water

See Figure 5-1 for procedure references. The following procedure assumes that
the unit has been inspected and the pre-operational checklist completed.
1. Close all butterfly valves.

2. Open discharge manifold valves (24) to (30) on the entire manifold.
3. Close downhole valves (not shown).

4. Close valves (2), (3), (7), and (8).
5. Attach water supply hose (not shown) to fill valve (33).
6. Fill the displacement tank using valve (6) to fill the left compartment. The
displacement tank selector Valve located on the front of the displacement tank
controls valves (5) and (6). The position of the handle on the valve indicates
which displacement tank compartment is being filled.
7. Close clean water valve (33) when the left displacement tank compartment is full.
The fill-up manifold on the front of the displacement tank has four connections,
which are used for the following:
• Mud line
• Sea water line
• Clean water line
• Connection at the end of the manifold for piping to the Auxiliary 5x6 when
used as a make-up pump, or when an external fluid-supplying unit can be
connected to the 4.0-in Fig. 206 union.
5.2 Dry Cement Supply Hook-Up Procedure
5.2.1 Pneumatic Feed System

Use the following procedure when the Slurry Chief cement inlet has a gooseneck
“Y“ connection.
Private
Each leg of the Y has a 4.0-in Fig. 200 female union along with a 4.0-in butterfly
valve. The valve numbers are (V1), (V2) and (V3) for the following procedure
(Refer Fig. A: Y Connection).
1. Connect the 4.0-in discharge hose to the cement supply source and to the 4.0-in
gooseneck connection (V1) on the Slurry Chief.
Note
Make sure that there are no restrictions in the discharge hose.
2. Close the butterfly valve on the gooseneck connection (V1).

3. Open the cement inlet butterfly valve (V2) that is not connected to a dry cement
hose and (V3). Make sure that (V3) is open in order to establish connection
with the main circuit.

4. If both cement inlet gooseneck connections are connected to a dry cement
delivery source, one of the butterfly valves on the gooseneck must be open
with air or dry cement flowing through the gooseneck inlet before the Slurry
Chief recirculation valve can be opened.
Note
It is good practice not to hook up a second hose to the gooseneck until just
before needing the material from that supply source.
5. The maximum air pressure delivery should be 15 psi. The air pressure should be
increased if the distance becomes too large for a smooth dry cement delivery
for the pumping rate, but it should be kept as close to the maximum pressure
or below. A standard distance of 10 to 15 feet should be kept for a smooth
cement delivery.
5.2.2 Gravity Feed System

1. Connect the Surry Chief knife gate inlet to the surge tank discharge connection
with a sock or hose adapter that connects to the 6.0-in Fig. 200 female union
on the knife gate.
Private
2. Make sure that the connection used between the knife gate and the surge tank
has a high degree of slope to the knife gate inlet. This decreases the chance of a
rat-hole effect on the dry cement delivery.
Note
An air vent line or vacuum breaker needs to be installed between the knife gate
and surge tank valve, or just below the knife gate in the mixer bowl, to provide
air when water or slurry is being recirculated through the Slurry Chief while dry
cement is not being delivered to the mixer. This will keep water or slurry from
rising toward the bottom of the knife gate and into the dry cement hose.
5.3 Testing Over-Pressure Shutdowns

1. Switch the master power switch on the control console to the on position.
This supplies 24 VDC to the console and unit.
2. Both front and rear engine throttles should be at the idle position.

5.5 Pumping Operating Functions
5.5.1 Pumping Operating Points of Concern

During triplex operation, ensure that the engines operate from 1,700 to 2,100
rpm to allow torque converter lockup.
Do not idle engines in excess of 15 minutes. When extended ikling is required,

increase engine speed to 1,000 rpm.
During mixing operation, operate the front engine at 2,100 rpm. The pressurizer
pump is directly coupled to the engine and requires an engine-operating speed
of 2,100 rpm. Pump discharge pressure rapidly decreases with minor decreases
of engine rpm.
Shift the transmission from neutral into gear while the engine is idling. When the
transmission is in gear, it can be shifted during full engine rpm. Engine rpm must
be high enough to make the transmission torque converter lock up.

close the displacement tank gravity valve (3) and open gravity valve (2).
Private
13. While the left compartment is being pumped out, fill the right compartment
by switching the displacement tank selector valve. This procedure is
performed until the job design displacement volume has been completed.

This resets the over-pressure condition, and restores throttle control to the
throttle control knob.
5.5.8 General Operating Tips

Keep the mixing tub level as high as possible to improve the suction head on the
5x6 centrifugal pump and improve mixing performance. As the level drops, the
pressurizer pump starts to cavitate, making the Slurry Chief more likely to shoot
slurry up toward the dry cement connection, which plugs the knife gate.
The pneumatic bulk system, with a moderate distance between the bulk unit and
the Slurry Chief mixer dry cement inlet, should be run at about 12 to 15 psi. A
bulk operator can measure the pressure needed by looking at the cement hose.
The hose should remain completely expanded by the air pressure and flow of
dry cement, while being drawn closed slightly by the vacuum produced by the
Slurry Chief in the recirculation mode.
A cone adapter is attached to the surge tank and knife gate on gravity feed
systems. The cone should have a high angle to reduce the possibility of rat
holing. This improves the dry cement flow-rate conditions.
Private
Potential Severity: Light

• The front engine must be at full throttle when opening the Slurry Chief
recirculation valve, and must also be at full throttle when closing the
recirculation valve.
• When recirculating through the Slurry Chief, either air or dry cement needs to
be flowing into the gooseneck. This also holds true if a gravity feed system
has an airtight connection between the surge tank and the knife gate.
• Always close the mix water valve on the jet manifold when not in use. The
Slurry Chief mixing bowl will fill with water if the Slurry Chief recirculation
valve (48) is not open when the mix water valve is open.

6.1 Inspect and Test Choke Stem in T-Body

Assembly
Since the beginning of 2010, FMC has started supplying the newly designed
shrunk fit two-piece choke stem in place of the original single-piece choke stem.
The FMC part number for this two-piece choke stem is P539999 B and is
stamped on all the choke stems as P/N P539999 B. Recently during a CAT test
at PPCS it was identified that one of these choke stems had a quality issue.
This issue was discussed with FMC who did a root cause analysis and
determined the issue was caused by a manufacturing defect that had escaped
their quality check. To further ensure that none of their other choke stems have
this quality issue, they torque tested all the choke stems in their stock for the
quality issue and confirmed that all of those choke stems are good to use. FMC
marked those tested choke stems with a center punch mark between "P/N" and
"P539999" (P/N P539999 B). They have also incorporated additional quality
checks to avoid this quality issue in the future. The choke stems with additional
quality checks will be marked with revision “C“ (P/N P539999 C).
Users should test the choke stems which are marked as P/N P539999 B (without
center punch mark) using the following procedure given by FMC to ensure that
the choke stems are good to use.
1. All users should identify the location of the choke assembly in the
high-pressure manifold of the unit. See Figure 6-1 for the choke assembly
location.

4. If the stem being used in the assembly is a two-piece stem and if it is

stamped as P/N P539999 B (without center punch) then test the two-piece
choke stem as per the procedure given by FMC. See Appendix A.1.1: Torque
Test Guideline for Checking Shrunk Fit Choke Stems, P/N P539999, In The
Field for the test procedure.

5. If the choke stem passes the Torque test, then add a center punch in between
P/N and P539999 B and replace the choke stem in the manifold.
6. If the choke stem fails the torque test, then scrap the choke stem and replace
it with a new choke stem. Order SWPS part number 101130360 for the new
choke stem.

Description:
Since the beginning of 2010 instead of single piece choke stem, FMC has started supplying the newly
designed shrunk fit two-piece choke stem. FMC part number for this two-piece choke stem is P539999 B
and is stamped on all the choke stems as P/N P539999 B. Recently during the CAT test at PPCS it was
identified, that one of these choke stems had quality issue.
Maintenance Bulletin # 1365-A
Page: 2 of 4
This issue was discussed with FMC and FMC did a root cause analysis to find that the quality issue
identified was due to some manufacturing defect, which escaped their quality check. To further ensure
that none of their other choke stems have this quality issue, they torque tested all the choke stems in their
stock for the quality issue and confirmed that all of those choke stems are good to use. FMC marked
those tested choke stems by centre punch mark between ‘P/N’ and ‘P539999’ (P/N . P539999 B). They
also have incorporated additional quality check to avoid this quality issue in future and the choke stems
with additional quality check will be marked with revision “C” (P/N P539999 C).
MB 1365 was released on Jan 2013 to provide corrective action to the locations to address this issue.
But again a similar failure was seen in during HHP test in a NAL facility in Jan 2014. (Refer to MB 1388),
a FMC choke stem tip separate from the shaft and gets lodged into the seat area. The stem was a 2-
piece shaft with part number P539999 C. Immediate cause of this failure is that the stem had the tip
welded in place to keep it from coming loose. This welding effect caused the metal to become brittle and
break off at the point of the weld.
This maintenance bulletin is to update MB 1365 with some additional corrective actions to
1) use only single piece choke stems when doing HHP test using unit’s choke
2) Torque test all existing two piece stems if it was not torque tested in the location before and use
those two piece choke stems only for pressure bleeding applications and not for any HHP tests.
Corrective Action:
1. All CPS 763/CPS 679/CPS 361/CPS 665/CPS 636/CPS 977users should, identify the location of
the choke assembly in the high pressure manifold of the unit. Refer fig 1 for the choke assembly
location.

assembly
Figure 1: Location of choke assembly
2. Remove the stem from the assembly. Refer intouch content ID 5794498 “Operation and
Maintenance manual of FMC T-body chokes” section 4.0 as a guidance to disassemble the choke
assembly. If it is the remote controlled unit, refer FCE Choke instruction in the same content as
guidance to disassemble the choke assembly from the actuator.
3. Inspect the stem and identify whether it is a single-piece stem or a two-piece stem. Refer fig 2 to
see the difference between single-piece stem and two-piece stem.
Page: 3 of 4
Figure 2: Single piece stem and two piece stem
4. If the stem used is a two piece choke stem with part number stamped as P/N P539999B or
.
P/N P539999 B or P/N P539999 C and if you have not torque tested it before, then test the
two-piece choke stem as per the procedure given by FMC. Refer InTouch content ID
6067286 for the test procedure.
5. If the two-piece choke stem passes the test then assemble back the torque tested two-piece
choke stem in the unit and use that only for pressure bleeding applications in the unit and not
for any HHP testing using unit choke stem.
6. Also torque test all the two-piece choke stems in the inventory with part number P/N
.
P539999B or P/N P539999 B or P/N P539999 C and keep them separately for future use.
7. Any new two-piece choke stems purchased in the future has to be torque tested until any
further notice.
8. If the choke stem failed the torque test then scrap that choke stem and inform InTouch.
9. For HHP test using unit’s choke, order SWPS part number 101130360 for the new single
piece choke stem and use that for the testing.
Equipment Affected:
The below list is the units identified by PPCS based on the serial number of HP manifold provided by
PPCS. However there might be cases where location might have directly ordered from FMC or changed
the choke stem between units. All units need to be inspected as per the FCO.

FMC P/N P539999 is a two piece stem assembly which consists of 4130 alloy steel stem and tungsten carbide
point. The stem and point are shrunk fit together to form the stem assembly. Figure 1 below is a cross-section
view of the stem assembly.
Figure 1: Cross-section - Stem Assembly
The part number and revision letter are stamped on each stem assembly in the location shown above. For stems
made to revision C, the format for this information would be: P/N P539999 C. Assemblies manufactured to
revision C or assemblies manufactured to revision B with a center punch mark between 'P/N' and 'P539999'
(P/N · P539999 B) have had a 100 ft-lb torque applied to the shrunk fit connection.
Assemblies manufactured to revision B which do not contain a center punch mark may be torque tested by
holding the stem and applying a torque (twist) to the point. Suggested steps for performing a torque test are
listed below.
1) Secure the stem in a vise or equivalent fixture. Note: Care must be taken to not damage the threads,
packing area, or point.
2) Using a 12" mole grip/vise grip or similar tool, grasp the non-tapered portion of the point and try to
turn the point.
3) If the point turns, it must be quarantined for further inspection and possible rework. If the point does
not turn, it is fit for use.

Maintenance Bulletin
Originator: Wang Xiao Bulletin#: 1426-B
Date: February 5, 2016 InTouch Content ID#: 6625109
Install Ball Valve on MARK III SLURRY CHIEF MIXER Hydraulic Supply Line
Aim of Bulletin:
Maintenance Bulletin 1426-A has been updated to Maintenance Bulletin 1426-B to correct an error
on the kit part number.
This Bulletin requires users of MARK III SLURRY CHIEF MIXER to check if a ball valve is installed on the
hydraulic line to the mixer. If not, it is required to install one as per instructions below.
The main reason for this MB is HSE concerns. Without isolating the hydraulic supply line completely, the
knife gate may move accidently during maintenance or inspection and injure the people performing the
job.
After installing this ball valve, it shall be closed and locked in place all the time if any maintenance or
inspection work is going on for the MARK III mixer.
Safety Considerations: Follow all applicable QHSE standards
Compliance: All work performed on equipment for this Bulletin must be recorded as a Work Order in Maximo.
The work order campaign for this bulletin is MB1426-B MARK III Ball Valve. Compliance can be
found in the Maximo program in the SLB MB Compliance Detail report. Access the report in the
program by following the menus: Reports>Work Orders>SLB Campaigns.
Maximo Equipment Assignment of this MB to the affected equipment will be done WSHQ.
Implementation Deadline:
The Maintenance Bulletin shall be completed at the next STEM II or before 31st December 2015
whichever comes first.
Responsibility:
Line Management is responsible for providing the necessary resources to complete the work described in
this Maintenance Bulletin before the deadline date. The Maintenance Manager/MSV is responsible for
(i) identifying the affected units in their location,
(ii) ensuring the work is performed on all applicable units before the deadline date, and
(iii) for documenting the completion of the work in the location for each applicable unit.
Maintenance Bulletin # 1426-B
Page: 2 of 3
Description:
This MB is to provide the users of MARK III SLURRY CHIEF MIXER with a procedure to install a ball
valve on the hydraulic supply line if it is not there.
Ball valve missing Ball valve installed
Corrective Action:
1. If MARK III SLURRY CHIEF Mixers are being used in location, check if this ball valve is missing;
2. If yes, order qty 1 of SWPS PN 101674041. This consists of the ball valve (item 1) and the fitting
nipple (item 2).
3. Discouple the quick-disconnect coupling (item 3) and 90 deg elbow (item 4).
