6. Gas Venting
Gas venting will be used to vent associated gas (annulus gas) produces from oil production activities
Design Principle:
Relevant Standard:
 API RP 14E—Recommended Practice for Design and Installation of Offshore Production Platform
Piping Systems, Section 5.8 pressure relief and disposal system
 Consideration:
1. The relief system and piping should be in a safe and reliable manner, prevent from lighting and
ignition.
2. The system and piping should be designed to prevent liquid accumulation and backpressure.
3. The pipe should be as smooth as possible: the relief line should be as straight as possible, and
sharp bend is not allowed.
4. According to the equation, combined with the experience for workover rig, the suggested gas
vent line should be at lest 2 inch.
5. All the valves, flange, hose and straight line can be work in 1000psi situation.
Construction Description
 The vent line is fabricated by the 3-1/2” pipe line.
 It divided into upper and lower parts, connected by flexible hose.
 The upper vent line is at inner side of upper derrick, lower part is outside of lower derrick.
 The far-driller side of mast already has standpipe and rotary hose (as shown in the picture Exhibit-
A7).
 The vent line is recommended to mount on the left side.
 The line cannot be welded on the derrick, it should be mounted by pipe clamp (as shown in the
picture Exhibit-A7).
 The hose connected two parts of relief should directly mount on the upper relief line.
 Top of relief line should be higher than the crown pulley by 2 m, point out at approx. 30 degree.
 A cap should be mounted to prevent rain
 A shutdown valve should mount on rig floor, to stop relief gas in emergency.
 Pressure gauge shall be considered.
 For easy installation and low possibility of gas leaking, the upright pipe should be in 4 parts,
connected by welding;
 The hose should be connected by union
Workover Rigs Services Page 11 of 14 Rig Specifications

 CONTRACTOR provide the flange to connect with CNOOC SES flange

 The flange provided by CONTRACTOR is welded with a union.
 The hose on the lower gas vent line connects to the union.
