lies at Producing Superintendent level or above.
2. PRIOR NOTICE
The responsible Saudi Aramco agency (Construction, Maintenance, Drilling, Project

Management, Marine, etc.) must contact the concerned Producing Superintendent a minimum
of 14 days prior to the commencement of any work activities within an offshore oil field to
inform him of the proposed work and arrange a date, place and time for the "Work Review and
Planning Meeting" (rig/barge move meeting). In the event that the Superintendent is not
available, this notice should be given to his designated representative as shown in
Supplement 1 of this Instruction. It is recognized that in some cases, 14 days notice will not
be possible due to uncontrollable situations. In these cases there will be no reduction in the
responsibilities of the concerned parties. The intent of this OIM will be met in all cases
regardless of the circumstances. Prior to any request for such meeting, the anchor patterns

* and any required revisions must have been reviewed and approved by rig move office on full
size charts scale 1:5000.

Vessel" and shall be responsible for the following:
4.2.1.1. Receive Work Permits, issued by Producing representatives, for marine

Offshore Unit movements in accordance with specific safe working
procedures agreed in the "Work Review and Planning Meeting". The
Offshore Unit’s movements requiring Work Permits will generally be
limited to marine Offshore Unit’s engaged in:
(a) Movement from safe anchorage (Supplement 4) into or out of designated

Saudi Aramco oil fields.
(b) Movement within designated Saudi Aramco oil fields where surface
platform facilities and/or subsurface producing facilities (pipeline, cable,
mud-line suspension wells, valves, etc.) are within 5 nautical miles of the
moving Offshore Unit or 1,200 feet of any Offshore Unit anchor pattern,
whichever controls.
(c) Movement alongside surface platform facilities and/or subsurface

producing facilities for purpose of anchoring/securing equipment prior to
undertaking drilling, construction, or repair activities.
(d) Movement into or away from work locations due to inclement weather
conditions and/or interference with other marine equipment.

** 4.2.1.2. Prior to the commencement of the rig move the Rig Move Master must
conduct a safety meeting onboard the rig/barge at which he highlights all
critical stages of the move and if pipeline(s) and/or sub sea cable(s) exist
in the vicinity of the rig/barge at the arrival location. The Rig Move Master
shall communicate clear instructions, as per the Rig Move Meeting
additional remarks, to the rig operator (i.e. Rig/barge Engineer or O.I.M.)
and the Rig Foreman on the safe anchoring position. A notice
prominently displayed in the Control Room shall indicate the safe position
of anchor drop point and the provisions of safe anchoring (i.e. spar buoy
and continuous subsea pipelines/cables buoying).
4.2.1.3. Upon receipt of the Work Permits, the Rig Move Master will be
responsible for the on-site acceptance of the marine Offshore Unit safe
work procedures, as agreed during the "Work Review and Planning
Meeting". These on-site marine Offshore Unit safe work procedures will
generally include:
(a) All items on the rigmove log book checklist. Supplement 5 of this
Instruction.

Meeting" and as directed on-site by the Rig Move Master appointed as a
"Servant of the Vessel".
4.3.2. Provide and maintain vessels and vessel crews that meet Saudi Aramco and
International Maritime standards and classifications.
5. BUOYING REQUIREMENTS
5.1. Actual buoying requirements will be determined at the "Work Review and Planning
Meeting" In general however, all sub sea lines and obstructions in the work area to a

radius of at least 600 feet beyond the usable length of anchor wire available must be
clearly delineated by buoys prior to the Offshore Unit moving into the location. These
buoys shall be color coded and so placed as to clearly indicate the direction and
position of all lines and or the outside limits of groups of pipelines and cables.
5.2 With the agreement of the Producing and Marine Department Representative the
requirement for buoying can be reduced if a construction spread is utilizing a Barge
Management System to deploy anchors. This requires the proving of the Barge
Management System under practical trials by the Rig Move Group and approval of the
system and surveying personnel by Saudi Aramco Hydrographic Survey Unit.
5.3. All underwater pipelines and/or cables within the area of the work site will be marked
by buoys in a manner agreed at the "Work Review and Planning Meeting".
5.4. All isolated piping special installations such as underwater valves, tie-ins and
crossovers within the area of the work site will be marked with a double buoy, as
determined at the "Work Review and Planning Meeting".
* 5.5. When a rig is on location, all underwater pipelines and/or cables in way of supply boat
anchors, loading or discharging at the rig, must be continuously buoyed. In congested
work sites a specific anchor location buoy will be placed. It is the responsibility of rig
Foreman personnel to ensure that the buoys stay on location and all vessels are
aware of any restrictions / specific dangers.
5.6. Safe anchoring areas within the oil field near the work site will be designated at the
"Work Review and Planning Meetings".
5.7. Obstacles along the route which are highlighted and classified during the Work Review
and Planning Meeting must be double buoyed.
*
6. MOVING OFFSHORE UNITS INTO, WITHIN, AND OUT OF OIL FIELDS
** ‘This section does not apply to drilling rigs and Saudi Aramco Owned / Chartered jack-up barges when
anchors are not utilized to facilitate their movements’
6.1. Movements during the hours of darkness or if visibility is less than 4 nautical miles
shall be made at the discretion of the Rig Move Master after prior consultation with the
Rig Move Office, Barge Captain / Superintendent and other Proponent groups.
Movements which can be expected under these conditions (i.e., - pipe lay, cable lay)
should be identified and discussed at the "Work Review and Planning Meeting".
6.1.1. Pipe laying barges and those wishing to adjust anchors may do so during
darkness if they have informed Producing through the Rigmove Master before
1400 hours on the day of the move and received permission/permit to do so,

* such proposed anchor movements must have been identified and agreed
during the Rig Move Meeting.
6.1.2. At the discretion of the Rigmove Master, short infield moves on anchors, not
under tow, may be made in daylight during reduced visibility.
6.1.3. All support vessels accompanying a construction spread can only move away
from or proceed to the work location within the oil field at the discretion of the
Rigmove Master. In congested locations the Rigmove master will provide the
routes for support vessels to follow to avoid damage to oil field surface and
sub-sea installations.
6.1.3.1. No Offshore Unit shall cross any existing pipeline without permission
unless there is a minimum of 5 meters (16 feet) clearance between
Offshore Unit keel or the foot of the barge legs and top of the pipeline
at LAT.
6.1.3.2. Hawsers, tow ropes or any other item must not be trailed in the water
at a lower level than the keel of the towing vessel.
6.1.4. All material barges that may be required to go alongside the crane / work / pipe
lay / or other must have at least one of the sides (port or starboard) clear with
no cargo / material overhang. This is to facilitate safe berthing.
6.1.5. All material barges must have an operational bridle recovery system. When not
in use the main and reserve tow bridles must be raised clear of the waterline.
Under no circumstances may a tow wire be permitted to trail in the water while
the barge is under tow.
6.1.6. The restriction on night/poor visibility movement does not apply to:
Supply boats
Tugs
Adjustment of position without moving anchors
Diving vessels
Other support vessels
All of which should navigate with caution at SAFE speed in accordance with
international regulations.
6.2. Movement off location or out of the field during inclement weather may be allowed at
the discretion of the Rig Move Master; after prior consultation with the Barge Captain /
Superintendent and others as he sees fit. These moves do not require a Work Permit.

6.3. All moves shall be along routes discussed at "Work Review and Planning Meeting",
however, deviation may be allowed at the discretion of the Rig Move Master in
consultation with Rig Move Office.
6.4. Divers and diving vessel may be required to be in attendance on vessel moves as
6.5. When moving the barge anchors, the barge shall be attended by three tug boats each
capable of handling the anchors and of adequate horsepower to safely tow the barge
against inclement weather conditions. One tug shall set the initial 4 anchors while the
other 2 vessels shall hold the barge in position. Exceptions to this general rule shall
be identified at "Work Review and Planning Meeting". Barges anchored in specified
safe anchorages (Supplement 4) shall also be provided with an attendant tug for each
barge at all times.
6.6. No Offshore Unit is to move into the oil field either to standby for work or to start work,
until all required buoys are in place and Work Permit covering the move has been
issued to the Rig Move Master by the Producing representative appointed by the
responsible Producing Superintendent to cover the work.
6.7. After review with the RTMOD and the responsible Saudi Aramco agency, the Work
Permit may be revoked at the discretion of the Producing representative if, in his
opinion, the move becomes hazardous to existing facilities and/or other Offshore Unit’s
working in the same area. In which circumstances the craft is to be removed from the
field at the earliest time.
6.8. These guidelines may be modified at the "Work Review and Planning Meeting", if work
is to be done in open locations with no existing commissioned facilities.
6.9. The foregoing guidelines apply to all construction barge movements into, within, or out
of oil fields and elsewhere where there are sub sea lines or facilities.
6.10. A situation may arise where Offshore Unit moves are not permitted or are halted by
either the Rig Move Master or Producing representative, when the responsible Saudi
Aramco agency and/or the Barge Captain considers such movements to be safe. As
Saudi Aramco is exposed to potential standby charges in these instances, a written
report in sufficient detail and completeness to allow evaluation of any claim shall be
issued to the responsible Saudi Aramco agency (Construction, Maintenance, Drilling,
Project Management, Marine etc.). The responsible party (Rig Move Master or
producing representative) shall issue this report within seven days.
**
7. MOVING DRILLING RIG AND JACK-UP BARGES
‘This section applies to jack-up drilling rigs and/or barges when anchors are NOT utilized to facilitate
their movements’

7.1 No drilling rig or jack-up barge is to move off/on a platform or into the oil field either to
standby for work or to start work, until all required buoys are in place and Work Permit
covering the move has been issued to the Rig Move Master by the Producing
representative appointed by the responsible Producing Superintendent to cover the
work
7.2 Prior to the commencement of the rig move the Rig Move Master must conduct a
safety meeting onboard the rig at which he highlights all critical stages of the move and
if pipeline(s) and/or sub sea cable(s) exist in the vicinity of the rig at the arrival location.
The Rig Move Master shall communicate clear instructions, as per the Rig Move
Meeting additional remarks, to the rig operator (i.e. Rig Engineer or O.I.M.) and the Rig
Foreman on the safe anchoring position. A notice prominently displayed in the Control
Room shall indicate the safe position of anchor drop point and the provisions of safe
anchoring (i.e. spar buoy and continuous subsea pipelines/cables buoying).
7.3 Movement within the field during the hours of darkness or if visibility is less than 4
nautical miles is prohibited
7.4 Rig move shall be along routes discussed at "Work Review and Planning Meeting",
however, deviation may be allowed at the discretion of the Rig Move Master No
Offshore Unit shall cross any existing pipeline without permission unless there is a
minimum of 5 meters (16 feet) clearance between Offshore Unit keel or the foot of the
barge legs and top of the pipeline at LAT. The positioning of a Rig in shallow water
gives implicit permission for supply vessels to reduce this requirement, the minimum
clearance and conditions to be discussed at the rig move meeting.
7.5 Divers and diving vessel may be required to be in attendance on rig/barge moves as
7.6 After review with the RTMOD and the responsible Saudi Aramco agency, the Work
Permit may be revoked at the discretion of the Producing representative if, in his
opinion, the move becomes hazardous to existing facilities and/or other Offshore Unit’s
working in the same area. In which circumstances the craft is to be removed from the
field at the earliest time
7.7 These guidelines may be modified at the "Work Review and Planning Meeting", if work
is to be done in open locations with no existing commissioned facilities
7.8 A situation may arise where Offshore Unit moves are not permitted or are halted by
either the Rig Move Master or Producing representative, when the responsible Saudi
Aramco agency and/or the Barge Captain considers such movements to be safe. As
Saudi Aramco is exposed to potential standby charges in these instances, a written
report in sufficient detail and completeness to allow evaluation of any claim shall be
issued to the responsible Saudi Aramco agency (Construction, Maintenance, Drilling,

Project Management, Marine etc.). The responsible party (Rig Move Master or
Producing representative) shall issue this report within seven days.
8 ANCHORING WITHIN THE OIL FIELD
* ‘This section does not apply to AHTSS and Supply Vessels when moving or supplying drilling rigs and
jack-up barges or Saudi Aramco owned chartered Dive Vessels carrying out required survey operations’
8.1. No anchor movement is allowed inside the oil fields without a work permit. Work
equipment is not to anchor inside the perimeter of the oil field, except at safe
anchoring areas or at buoyed work sites. No dropping of anchors is allowed within an
oil field except as directed by a Rigmove Master and for this reason, three assisting
vessels all of which must have anchor handling capability, must be in attendance for all
moves, two to tow and one to set and recover anchors. The supply and backup
vessels are in no way permitted to be tied into any platform. Offshore Unit’s are not
permitted to anchor at work sites until a Move In and Set-Up Work Permit has been
issued by the responsible Producing representative. Offshore Unit’s may anchor within
the confines of a safe anchoring area without a Work Permit.
8.2. Anchors for work Offshore Unit’s are not to be set or picked up at a work site until the
responsible Producing representative has issued a Work Permit covering the action.
8.3. Where an anchor cable is to cross a sub sea pipeline, the anchor must be at least 600
feet across the line if it is depressurized and 1,200 feet if the line is "hot".
8.3.1. If any anchor wire lying across a sub sea line is in contact with or likely to be in
contact with that line, it must be supported at the crossing by parachute /
buoyancy / DP buoys to avoid damage. Damage prevention buoy locations will
be determined at the Rig/Barge Move Meeting and after setting will be marked
with a distinctive buoy to facilitate inspection.
8.3.2. Where an anchor is laid up to a pipeline but not across, it should be a minimum
of 300 feet from the line.
8.3.3. The requirement for anchor wires run across pipeline/cable will be determined
at the "Work Review and Planning Meeting". Producing Department will have a
representative on duty at the job site to issue the Work Permit. Similar to the
Rigmove Master this representative will have to have single accommodation
aboard the marine craft on certain jobs.
8.4. Prior to setting anchors, the anchor location will be buoyed and dive checked if
required.

8.4.1. If anchor handling vessel is fitted with survey equipment, anchors may be set
and dive checked afterwards. Survey vessel checks may also be used to
confirm locations and for drag watch on buoys.
8.4.2. No anchors shall be moved across existing pipeline while anchors are
suspended from anchor handling tugs or barges. All anchors must be on deck,
with a safety strap/wire installed if they are to be moved across a pipeline.
8.4.3. No anchor may be moved such that the anchor cable sweeps along the
pipeline.
8.5. When the agreed anchor position is deemed "critical" due to proximity to existing
surface or underwater facilities or due to potential interference with anchor patterns of
other Offshore Unit’s working in the same area, a diver will be required to "spot"
anchors as they are set and ensure they are clear. Divers will be required to "spot"
anchors as determined by the Rig Move Master.
8.6. All anchors will be fitted with wire pendants of adequate length for the water depth with
suitcase style buoys. The wire pendant must be secured to the "crown" of the anchor.
8.7. No Work Permit is to be issued until all required buoys are installed and all necessary
lines inside the area of operation required to be shut in have been depressurized.
Deviations from this procedure, if required by operational contingencies, will require
approval from the Superintendent or higher Producing Management.
8.8. After work has started, no anchors are to be moved until the responsible Producing
representative has issued a Work Permit covering the move.
8.9. When entering, leaving or moving within an oil field, all anchors must be hove in and
secured by a safety strap in the case of anchors connected by wires. Where anchors
are connected by normal chain with purpose built gypsies, the compressor or
Guillotine arrangements must be operational and in use.
8.10. No vessels other than those approved by the Producing Department shall berth at
existing Offshore Platforms. Vessels working at existing platforms must moor in a safe
and seaman-like manner to avoid damage to the platform and themselves. "No work
vessel shall remain alongside existing platforms during the hours of darkness, but
must proceed to a safe anchorage for the night". The provisions of Sections 7.1 and
7.2 above apply to the anchoring of such vessels. "But this prohibition may be waived"
for contractor's vessels at the discretion of the Operations Superintendent.
8.11. Where crossing of a pipeline or setting of anchors may be potentially hazardous, or

present difficult working conditions, offshore units may "Soft Line" to the legs of a
conventional pile driven jacket. A "Soft Line" is a synthetic or natural fiber rope which
is secured by a shackle to a conventional anchor/mooring wire to form a "bight", which
is passed around the leg of the jacket. (Producing consent).

Prior to soft lining, the contractor must submit to the RT Marine Offshore Operating
Division Rig Move Office the following data:
(a) The type and size of rope to be used.
(b) Certificates of test, or calculations showing the safe working load and breaking
strain of the rope.
*
(c) The Maximum amount of stress / strain to be used.
* Formal consent to "soft line" should be sought at the work planning meeting, and final
approval will be given by the Operations Superintendent, at the Rig Move Meeting.
Soft Lines are to be regarded as a Last Resort, permission for the use of soft lines will
not be granted as a rule. Each case will be looked at separately and the age /
condition of the platform will be taken into account. Where soft line use is approved, it
must be removed as soon as possible and definitely before the departure of the barge.
** 9. ANCHORING AT RIG/JACK-UP BARGE LOCATION FOR SUPPLY PURPOSES
9.1 The vessel must obtain prior permission from the Rig Foreman before approaching any
Offshore Rig/Barge. Rig foreman or his delegate must give the supply boat clear
instructions on the safe anchoring location as indicated in the rig move meeting.
9.2 No anchoring is allowed at any location where there is a subsea pipeline or cable
within 400 meters of the rig. In congested areas this may require the use of DP
Vessels only to supply the Rig.
9.3 When a rig is on location, all underwater pipelines and/or cables in way of supply boat
anchors, loading or discharging at the rig, must be continuously buoyed as indicated in
the Rig Move Meeting Minutes. In congested work sites a specific anchor location
buoy (Spar Buoy) shall be deployed. It is the responsibility of Rig Foreman to ensure
full compliance with the provisions of safe anchoring (i.e. spar buoy and continuous
subsea pipelines/cables buoying).
9.3 Where there are any pipelines or power cables in the vicinity of any rig, a notice will be
placed on the rig in the control room by the Rig Move Master relocating the rig. The
notice shall be also passed to all vessels via the Marine AHTSS foremen at Tanajib to
be kept on the bridge, instructing all vessels where anchoring is prohibited and where
the safe anchoring position is located. The Drilling Foreman, as the Saudi Aramco
Representative on board the rig, will be also given a copy of the notice and will observe
its enforcement.

9.4 When Anchoring at the Rig/Barge location the drop anchor position shall be cross
referenced by all available means and verified by two qualified officers.
9.5 The anchor drop position and the checks made thereafter shall be recorded in the
vessel Log Book.
9.6 Where a Spar Buoy has been deployed at a Rig/Barge location to indicate the safe
anchor drop position, the Master of the supply vessel shall use the Spar Buoy purely
as an aid to navigation, and shall not use the buoy as an exact required anchor drop
position. Masters must consider the buoy to mark the most extreme distance for
anchoring from the Rig/Barge, and should anchor between the Spar Buoy and the side
of the Rig/Barge, and NEVER on the far side of the buoy.
9.7 The Spar Buoy will be deployed by a survey vessel (e.g. Karan 8) to ensure the correct
positioning of buoy. The vessel used to position the Spar Buoy will enter the exact
position of the Spar Buoy in the Deck Log-book. A survey Work Order must be raised
by the Drilling Foreman for the positioning of the Spar Buoy.
9.8 The Master of the supply vessel will ascertain whether the Spar Buoy is in the
correct/agreed position. If the Master has any doubts about the position of the Spar
Buoy, he shall immediately report this to the Rig Foreman and the Rig Move Office.
9.9 The Master of the supply vessel shall use all available navigation aids (e.g., Radar
Range & Bearing or DGPS) to ascertain anchor drop position. The use of GPS or
visual reference of the Spar Buoy is not acceptable as an exact means of ascertaining
the correct anchor drop position.
9.10 The Master of the supply vessel shall, as practically as possible, lay the anchor cable
in a straight line from the anchor drop position to the side of the Rig/Barge.
9.11 When letting go from the Rig/Barge and recovering the anchor, the Master will
maneuver the bow of the vessel directly back along the anchor lay in such a manner to
prevent the anchor being dragged along the seabed.
9.12 On departure from the Rig/Barge location the Master of the Vessel will immediately
report to the Rig and the Marine Department any difficulty in recovering the Anchor,
especially if the anchor is fouled.
9.13 These conditions for the use of anchors by Dive Support Vessels for the survey of
locations shall be followed where applicable.
10. DEPRESSURIZING UNDERWATER PIPELINES AND PLATFORM TOPSIDE

PIPING; AND DE-ENERGIZING SUBSEA CABLES.
10.1. Construction work by floating barges

10.1.1. If pipe laying barges are to work in the vicinity of existing underwater
commissioned pipelines, critical lines that are inside the agreed area to be
covered by the lay barge anchor system shall be shut down and depressurized
before the lay barge is moved into the position. The lines will not be returned
to service until the pipe laying barge anchor spread is 1,200 feet clear of said
lines unless otherwise agreed at the "Work Review and Planning Meeting" by
Producing Superintendent. No pipe is to be laid, repaired or altered until the
responsible Producing representative has issued a Work Permit covering the
work.
10.1.2. On a platform where riser installations and/or modifications to the topside

piping are being made, all topside piping as well as all piping connected to that
piping, and critical underwater pipelines inside the area covered by the work
barge anchor system shall be shut down and depressurized before the work
barge moves in, sets anchor(s), does the work, and moves from the platform.
Unless otherwise agreed as in Step 8.1.1 above, platform topside piping must
be depressurized and drained (blinded or double blocked and bled if
necessary) if the risers are to be connected to an unvalved piping connection.
No work is to be done until the responsible Producing representative has
issued a Work Permit covering the installation.
10.1.3. For platform installation adjacent to an existing platform, the guidelines

presented in Step 8.1.1 above will apply.
10.1.4. An underwater pipeline that is to be modified and critical nearby lines that are
inside the agreed area covered by the work barge anchor system shall be
depressurized before the work barge is moved on location to set anchors.
10.1.4.1. No pipeline deemed critical shall be returned to service until all work
has been completed and the barge has moved off location if frequent
anchor moves are required during the course of the work. If frequent
anchor moves are not required, all pipelines outside the area of the
barge anchor system, except the pipeline is being modified, may be
returned to service at the discretion of the responsible Producing
Superintendent while work is in progress, unless otherwise agreed
as in 8.1.1 above.
10.1.4.2. All such pipelines shall be shut down and depressurized for all
anchor moves that occur after work has been started, unless
otherwise agreed as in 8.1.1 above.
10.1.4.3. The pipeline that is to be modified shall normally be scraped to

displace the oil in the line with water prior to the start of work if the
work involves cutting or opening the line for any reason.

(NOTE: If scraping is not practical, alternate means of eliminating oil

spillage into the sea from the line will be developed by the
appropriate Producing Division Head. "Jelly Scrapers" may be
considered.)
10.1.4.4. No work will be done on the pipeline until the responsible Producing
representative has issued a Work Permit covering the work.
10.1.5. When sub sea power & communication cables are inside the agreed area to be
covered by barge anchor system, the position of the cable is to be confirmed
prior to the deployment/movement/recovery of any anchors.
10.2. Construction work by jack-up construction barges, so long as these barges are moving
in, jacking up, jacking down, or leaving a work site:
10.2.1. The rules outlines in Paragraph 8.1 above apply to jack-up construction barges,
so long as these barges are moving in, jacking up, jacking down, or leaving a
work site, or at any time when anchors are deployed.
10.2.2. While the barge is working jacked up and anchors are not deployed all piping
lying more than 300 feet outside the maximum working radius of the barge
crane shall be considered as outside the "area covered by the anchor system
of the work barge", as long as the vessels or barges do not need to deploy
anchors alongside the jack-up barge.
Dive checks may be required for leg penetration and to make sure that legs are
clear from any underwater pipelines and structures (before the legs are finally
lowered to the seabed when in close proximity to pipelines).
10.2.3. No vessels may tie up to the legs of a jack-up, or come alongside a jack-up
barge in the process of operating its legs without the expressed permission of
the person responsible for the jack-up.
10.2.4 The rules as outlined in Paragraph 8.1 above apply without modification during
the entire period they remain on location.
10.3. Construction Work by Dynamic Positioned (DP) Vessels
10.3.1. DP vessels shall be used only in water depths within the vessel certified limits,
but in any case not less than 10 meters.
10.3.2. Three (3) independent DP reference systems shall be used with the DP
system. Each reference unit shall be a stand alone system. Multiple receivers

of a single reference system (e.g., DGPS receivers) shall be regarded as one

reference system regardless of how independent each receiver/unit is.
10.3.3. A Rigmove Master will remain on board D. P. vessels throughout their stay
inside the oil fields or other areas considered sensitive to damage.
10.3.4. The responsible Saudi Aramco agency and Contractor representatives shall
present full details/justification of the vessels operational characteristics and
systems criteria at the "Work Review and Planning Meeting" to support its
classification as a DP vessel, fully capable of performing the work safely and
without the use of anchors. The DP Vessel must be classed as such and meet
IMCA Recommendations for minimum of DP 2, or such other requirements as
recommended by IMO if their requirements have been upgraded. Final
approval of the DP classification shall be given by RTMOD based on on-site
sea trials which fully simulate the work to be undertaken.
10.3.5. As long as the DP vessel performs the work without reliance on anchors, the
restraints on pipeline depressurization and sub sea cable de-energization
covered in Paragraphs 8.1.1 and 8.1.5 above will generally not apply.
10.3.6. When existing pipelines are to be cut or modified, positions derived from a
satellite navigation system MUST be verified by conventional navigation
methods, prior to commencement of work.
10.4. Maintenance Work
10.4.1. The guidelines outlined in all preceding paragraphs generally apply to

Maintenance work in offshore oil fields.
10.5. Workover/Drilling Work
The guidelines outlined in all preceding paragraphs generally apply to workover/drilling

work on offshore wells. Detailed work procedures will be defined at "Work Review and
Planning Meeting" held as required with the concerned Producing Superintendent,
Drilling representatives and Rig Move Coordinator in attendance.
11. ASSISTING VESSELS
11.1. Towing vessels must be of a suitable horsepower/bollard pull to be capable of handling

their tows in all likely conditions to be expected in the Arabian Gulf. The Marine
Department will have the final decision on the adequacy of a towing vessel's

* horsepower/bollard pull. Every Towing / AHT vessel must have Sharks Jaws or
Similar system fitted and operational.
11.1.1. Every barge at a work site, material transportation or other, shall have a
dedicated tug, capable of towing the barge, attending it at all times.
11.1.2. Dedicated tug will not leave the locality of the work site unless replaced by an
adequate substitute.
11.1.3. Sections 11.1.1 and 11.1.2 do not apply to jack-up barges having an air gap of
six feet or more and in a pre-loaded condition.
11.1.4 Where vessels are used for Anchor Handling Operations on a 24 hour basis
such as during pipe lay operations then two masters must be on such anchor
handling vessel and sufficient manpower for 24 hour operations. In such
instances Rig Move Masters will be provided by Offshore Projects Department,
the number to be determined by RTMOD, who will also approve such Rig Move
Masters. Such Rig Move Masters proposed cannot be or have recently been in
the employ of the contractor, and must be provided through an independent
third party. The Rig Move Masters so provided shall be responsible solely to,
and report directly to the Rig Move Coordinator.
11.1.5 Where Anchor Handling Vessels are utilizing Barge Management System to set
or recover anchors, sufficient survey personnel must be on board the Anchor
Handling Vessel to monitor / service / calibrate the survey equipment during the
entire period of utilization.
11.2. Tug assistance will be related to displacement tonnage of the tow in the following
manner:
11.2.1. Jack-up drilling rigs - two by 5000 BHP (Brake Horse Power) with a bow-
thruster providing a minimum of 6 Tones thrust departing locations or under
tow, and three by 5000 BHP vessels and bow thruster of 6 tones thrust for
positioning at platforms.
11.2.2. Construction Barges are to be attended by two anchor handling vessels at all
times, each vessel to have a minimum horsepower of 5,000 BHP and bow-
thruster with a minimum thrust of 6 Tones. During initial set up or recovery
period for first and last 4 anchors, construction barge must be held in position
by two tow vessels, and a third vessel used for those four anchors first
deployed or last recovered.
*
11.2.3 In special circumstances where constructions barges are entering congested or
sensitive areas the barge must be attended by three Anchor Handling Vessels
at all times, each vessel to have a minimum horsepower of 5,000 BHP and

bow-thruster with a minimum thrust of 6 Tones. A Push Pull Tug requirement

may be enforced in certain circumstances where this will enhance safety.
**
11.2.4 The Horse power requirement may be raised as appropriate where the Barge is
above 15000 Tonnes displacement, or where heavy lift vessels are involved.
**
11.2.5 Where AHT Vessels are required to handle Gravity Blocks, the winch must be
a minimum of 100 Tonnes, and be proved to be capable of handling the gravity
blocks.
**
11.2.6 Vessels required to handle Gravity Blocks must be capable of double securing
such blocks.
**
11.2.7 For Shallow Water (Less than 10 Meters LAT) either vessels with A Frames
capable of decking the Gravity Blocks, or spud Barges with similar capability
must be used.
11.2.8 Shallow Water Spreads must comply as closely as practical with the
horsepower requirements, but the main emphasis will be on draft restrictions
and the proven capability of the vessels to perform the operation in shallow
water.
11.2.9. Twin screw vessels are mandatory.
11.2.10.Horsepower shall be that of the main propulsion engines at 100% MCR

(Maximum continuous running) only and Brake Horse Power as opposed to
Indicated Horse Power. The towing vessel must provide a recent bollard pull
certificate (less than 90 days from issue). The bollard pull to Brake Horse
Power ratio must be a minimum of 1.1 metric tons per 100 BHP. The bollard
pull certificate shall be renewed at intervals not exceeding one year.
11.2.11.Tonnage shall be displacement at maximum permitted draft as assigned by

classification Society or Certificate of Registry.
12. CONDITIONS OF PROVISION OF PILOT SERVICES
12.1. No rig or barge may move within an oil field without a Rigmove Master onboard.
12.1.1. The Rigmove Master will remain onboard until he is satisfied the move is
completed and the barge/rig is in safe condition.
12.1.2. In the case of jack-up rigs, 12.1.1 usually means completion of pre-loading
and final diver leg check.

12.1.3. In the case of floating barges riding to anchors, Rigmove Master Service may
be continuous as it will with moving pipe layers and dredgers.
12.2. The document "Provisions of Pilotage Services" (Supplement 6) shall be presented to

all Contractor barges and to all Contractor Drilling rigs for signature by
Superintendent/Master of the unit, prior to provision of any pilotage or rigmove master
service. This document will not be presented to Contractor Barge Superintendents if
