STRUCTURES A & E, MELLITAH COMPLEX EXPANSION & CO2 MANAGEMENT INTEGRATED DEVELOPMENT PROJECT

PRODUCTION PLATFORM E

Mellitah Oil & Gas B.V. (MOG) intends to enhence its production by adding new offshore and onshore production facilities, under STRUCTURES A & E, MELLITAH COMPLEX EXPANSION & CO2 MANAGEMENT INTEGRATED Development Project. The Overall Development will be implemented on individual projects basis; including an EPIC Project for PRODUCTION PLATFORM E. MOG would like to invite the interested EPIC Contractors who are qualified and experienced to express their interest to participate in the Tender of EPIC, by submitting a Prequalification request to Company. Information about the Project and the Participation requirements are detailed herefollowing. 

PROJECT DESCRIPTION

The overall E structures develeopment project foresees the exploitation of Structures E located in the Libyan offshore area of NC 41 Block. “E” Structure is located in the central-eastern part of the NC 41 Block area, about 130 Km from the Libyan coast, in a water depth ranging from 205 to 235 m.

DEVELOPMENT SCENARIO

The PPE Platform is an eight legs production platform with twenty (20) slots. The PPE platform is a treatment and compression platform to be installed in 218m water depth. Topside is componsed of a Single Integrated Deck, Flare, Living Quarter, and Compression Module. 

A Single Integrated Deck (SID) configuration is requested in order to minimize the offshore installation and hook-up activities. SID, Flare and LQ may be installed separately (i.e. 3 offshore lifts) (to be confimred).

The SID will host main process and utilities and is endowed with six levels (El. +20.000 m TOS, El. +28.000 m TOS, El. +36.000 m TOS, El. +40.000 m TOS, El. +46.000 m TOS and El. +55.000 m TOS) with footprint of 39 m x 78-104 m. 
The Platform will be designed to receive and treat the well fluid coming from both wells drilled from platform and subsea wells. The treated gas and the oil/condensate are then sent to Mellitah onshore plant via sealines (Sealines and subsea development are outside the scope of this pre-qualification).

The well fluid is treated by means of two trains (2 x 50%) where separation of gas from the associated condensate / water occurs and gas compression up to the required export pressure and gas dehydration to the required water dew point is performed. The installation of a raw gas compression system is also foreseen.

The separated condensate is partially stabilized with the well fluid coming from oil wells by means a two stages flash operation in a single train. The gas recovered during condensate partial stabilization is compressed back to the gas conditioning facilities.

The process facilities foreseen on PPE are the following:
•	Unit 100 ‐ Platform Wellheads (20 wells);
•	Unit 130 ‐ Production Manifold (4 manifolds);
•	Unit 190 ‐ Pig Launching Facilities;
•	Unit 300 ‐ Gas Separation and Metering;
•	Unit 310 ‐ Gas Dehydration (2 trains);
•	Unit 320 ‐ Condensate & Crude Oil Treatment & Recovery;
•	Unit 360 ‐ Raw Gas Compression;
•	Unit 360 – LP, MP Flash Gas Compression (from condensates/oil).
•	Unit 380 ‐ Glycol TEG Regeneration

The following main Utilities are also foreseen to support the production:
•	Unit 120 ‐ Chemical Injection system
•	Unit 230 ‐ Flare, Vent and Blowdown system
•	Unit 420 ‐ Fuel Gas system
•	Unit 430 ‐ Diesel Oil system
•	Unit 460 – Compressed Air system
•	Unit 470 – Main Power Generation (3x50% Turbogenerators)
•	Unit 480 – Emergency Power Generation system
•	Unit 500 – Sea Water system
•	Unit 520 – Cooling Water system
•	Unit 530 – Fresh Water system
•	Unit 550 ‐ Closed Drain system
•	Unit 540 ‐ Open Drain system
•	Unit 560 – Produced Water Treatment System
•	Unit 570 ‐ Sewage Treatment System
•	Unit 600 – Nitrogen Generation
•	Unit 650 – Antibiofouling
•	Unit 730 – Fire Water System

PPE will include a Living quarter (120 people) with upper mounted helideck as a cantilevered structure on the side of the platform.

Expected overall topside dry weight is around 24000 t (excluding Fast Moving Workover Rig – out of present SoW).

Expected weight of SID in installation conditions is about 17300 t.

The jacket is a lattice structure with eight legs, to be installed by means of launching operations.
The structure has the following main characteristics:
•	Top dimensions: 27m x 50 m;
•	Base dimensions: 70 m x 78 m (sleeves excluded);
•	Overall height: about 230 m;
•	Deck interface: El. +13.50 m LAT;

Platform foundation is composed of no. 28 piles with OD 108” x 60-85 mm driven to a target penetration of about 88m (overall length about 120 m). 
Overall jacket weight in launch configuration is 44000 t inclusive of about 6000 t of buoyancy tanks 

The provided data are provisional, and to be confirmed.

Installation Method for PPE Topsides-  Attachment-2 SOW
	Considering COMPANY (Mellitah Oil and Gas B.V Company)'s development scenario in Attachment-2-SOW that SID (Single Integrated Deck), Flare and LQ may be installed separately (i.e. 3 offshore lifts), Bidder understands that COMPANY currently prefers ‘heavy lifting’ installation method for the topside of PPE (“Production Platform E”) rather than ‘float-over’ method. 

Based on past experiences, however, Bidder believes that the float-over method could be more advantageous in terms of both cost effectiveness and offshore installation & hook-up work optimization.

COMPANY is kindly requested to confirm that heavy lifting installation method is mandatorily required or other installation method (i.e. float-over) is also acceptable.

	Heavy lift  is not mandatory. However, it is the COMPANY's preferred installation method as it would not require any modifications to the current base design case.
Float-over installation using the Allseas Pioneering Spirit installation vessel could be a viable alternative and it is currently being considered as part of the FEED design activities. It is expected that some design changes will be required which will involve either extension of the topsides leg (preferred option) or strengthening of the cellar deck cantilever areas depending on whether the horseshoe or the yoke method is used respectively.
Conventional float-over installation using a barge-type vessel is not acceptable for various reasons including limited workability, jacket slot requirement, loadout frame requirement and significant vessel customisation.

Weight of Jackets
- Attachment-2 SOW
	Bidder understands that the provided Jacket weight, 44,000 ton includes the piles (28 ea) weight as well as buoyancy tanks (6,000 ton).

For Bidder's preparation of T&I plan, COMPANY is kindly requested to provide separate weight of jacket and piles with confirmation on HHI's above understanding. 

	According to the current design, the jacket gross launch weight (i.e. including the buoyancy tanks) is 43,689t. Please note that this weight includes a contingency (weight allowance factor) of about 16%. 
The gross pile weight is 17,369t. This figure includes a contingency of 10%.
However, the provided weight information at this stage should be treated as very preliminary and hence indicative only.

Weight of Topsides
- Attachment-2 SOW
	Bidder understands that compression module will be integrated into SID prior to sail away and therefore, SID weight, 17,300 ton includes Compression Module weight as well.
COMPANY is kindly requested to confirm that Bidder's understanding is correct and also provide the approx. weight of Compression Module, LQ and flare respectively.	FEED Design of the PPE topsides is still ongoing so definitive information cannot be provided at this point. However, a level of integration of the Compression Module is indeed anticipated.
No weights of the Compression Module, LQ and flare can be provided at this stage.
