5 PROJECT DESCRIPTION

The XXXXfield is QATAR’s largest oil field. It is a conventional oil field (of approximately 60 m water depth) situated offshore the State of Qatar approximately 70 km north-north-east of Ras Laffan. The field overlays the giant pre-Khuff gas field known as North Field.

Thirty-three platforms, including five production hubs, are installed in XXX field. These are spread over nine different areas across the field - Locations A to I. Crude is exported by tanker via tandem offloading from two FSOs which are permanently moored in the field to two (of three) SPMs. Gas is gathered in a gas grid pipeline system and exported via North Field Alpha.

The field has been developed through several phases and further development phases are envisaged by COMPANY as operator of the AXX concession.

The new facilities shall make use of the full design envelope of the existing facilities; best possible use will be made of existing installations to maintain the production plateau.

As a base case, platforms shall be designed for full 24 well-slot access and operation using 60-foot drilling jack-ups on one defined footprint.


6 PRESERVATION PLAN

Equipment are after being dispatched from factory/workshop after initial preservation at vendor shop and until the equipment are in normal operation on site, all of them might spend some time in transportation, storage, on stand-by, etc... During this time, equipment can be exposed to a number of aggressive environments or situations and could be deteriorated/ damaged. Ensuring integrity and functionality of an equipment is critical in keeping its availability through that time and at the time where it will be required for service.

In order to safeguard the integrity and functionality of equipment, it is necessary to preserve it, taking in consideration the following criteria’s as a minimum:

 Weather conditions: condensation, sun radiation, frost, water ingress, dust, etc.

 Local conditions: corrosive atmosphere, presence of sand, etc.

 Duration: long term v/s short term preservation requirement, expiry date of consumables, etc.

 Functionality: Mechanical deformation when not running, seizing, external chocks, etc.

 Project phases: Storage, construction, transportation, handling, Pre-Commissioning, Commissioning, stand-by time etc.

A log sheet (Appendix 3) shall be completed for each equipment item or package requiring preservation and used to record preservation activities as they occur.

All the individual preservation activities with each equipment item number, the type of preservation performed (PRSV form), date of each activity was performed shall be recorded. The original documentation will be maintained by CONTRACTOR and ultimately turned over to COMPANY with the project quality records.

The Preservation related activities shall be prepared and tracked using ICAPS from commissioning phase until the equipment is formally transferred to Company.

The Preservation history and records shall be made available at any time until the equipment is formally transferred.

APPENDIX A.1 DESIGN RECOMMENDATIONS VS BOLTING 11


1.0 GENERAL NOTES

This procedure for tightening of bolts is valid for all bolted connections as long as no other information

concerning the tightening moment is given in a mounting procedure or on an assembly drawing.

Standard (General) bolt tightening moments are shown in Chapter 2.0. Bolt tightening moments for

Flat Ring gaskets for flange facing Raised Face (RF) according to ASME B16.5 Class 150 have been

especially evaluated in Chapter 3.0 with respect to bolt material, gasket crush strength, flange

material allowable stress and lubricant friction coefficient. For Full Face gaskets for flange facing Flat

Face, use tightening moments in Chapter 2.0.

Bultens recommendations concerning calculation of the required tightening moment from the

prestressing force when including scatter have been applied for torque-controlled tightening. If

pneumatic or electric hammer is used during assembly, this should be used for light tightening,

followed by tightening with a torque wrench.

If no tightening moment is specified in service instruction or on drawing, use tightening moment

according to following tables which are based on recommendations in BULTENS HANDBOOK BH 67.

BULTEN gives an improvement in the calculation method compared to VDI 2230, “Systematic

Calculation of High Duty Bolted Joints” since it includes the possible scatter in the prestressing force.

A scatter of 23 % (assembly uncertainty factor) is used with torque-controlled tightening with a torque

wrench. Framo Standard calculation procedure 2025-026-4 is used for calculation of all tightening

moments included in this document.

In order to obtain correct prestressing force, it is essential that the threads of cap bolts and threads

between studs and nuts, plus screw heads and contact surface of nuts against foundation, are clean

and lubricated before tightening (see figure below). The friction factors μ for Molycote (2 types),

Chesterton 785 and Loctite 243 threadlocker are based on data from Statoil TR 3125 and tests

performed by Frank Mohn Flatøy (1995).

Suppositions For the Tables:

a) Connected components should have metallic contact.

b) Screws and nuts should be paired, A4-80 / A4-80, 8.8 HDG / 8.8 HDG etc..

c) Tightening moments are based on lubrication of both the threads and under bolt head / nuts,

except for Loctite threadlocker that shall only be used on threads and not under bolt head /

nuts.

d) Special for Flat Ring Gasket for Flange Facing Raised Face (RF):

Retighten all flange bolts after 24 hours due to gasket shrink and creep under load.

Retighten all flange bolts after 24 hours due to gasket shrink and creep under load.
Tightening of Flanges:
When tightening flanges with circular hole pattern:
1. First tighten one round (diagonally) with ¾ of full tightening moment,
2. Then with full tightening moment until the bolts are firm and without movement when full
tightening moment is achieved.
