Heerema won Alba third compression platform EPCI
In April 2013, the Houston-based Marathon Oil Corporation (Marathon) and its partners, Noble Energy (Noble) and the Compania Nacional de Petroleos de Guinea Ecuatorial (GE Petrol) awarded the engineering, procurement, construction and installation (EPCI) contract to Heerema Fabrication Group (HFG) for the Alba PSC B3 gas compression platform.
To be located offshore Equatorial Guinea, the Alba gas field lies by 75 meters shallow water depth of the West Africa Continental Shelf, 32 kilometers north of Bioko Island.
Discovered in 1984, the Alba wet gas field entered into production in 1991.
Since 2002, Marathon, through its local subsidiary Marathon Equatorial Guinea Production Ltd (GE Petrol) is developing the non-associated gas of the Alba field with Noble represented by its local company Samedan of North Africa Inc. (Samedan), and the local CNPGE.
All together they share the working interests in the Alba gas field in the following way:
– Marathon 63% is the operator
– Noble 34%
– GE Petrol 3%
Marathon to ramp up gas supply to Bioko Island LNG
– 52% in the Alba liquefied petroleum gas (LPG)
– 45% in the Atlantic Methanol Production company (AMPCO)
– 60% in the Bioko LNG plant.
In this context and in respect with the remaining reserves of the Alba wet gas field, Marathon and its partners, Noble and GE Petrol, have decided to continue the development of the Alba field with a third gas compression platform.
This B3 platform should be bridged to the existing B2 platform.
With a total weight of 6,000 tons, the topsides should count for 4,500 tons and the jacket for the remaining 1,500 tons.
These topsides have been designed to fit in a cube of 40 meters side and the jacket as a square of 33 meters side supported by 81 meters height legs.
– 990 million cf/d of natural gas
– 75,240 b/d of condensate
Heerema will subcontract the process part of the detailed design to lv-Oil & Gas also from the Netherlands.
In close co-operation with Marathon, lv-Oil & Gas will executes its section of the contract from its Houston, Texas, office.
The transportation and installation will be performed by the Heerema Leiden office in The Netherlands.
The flare structure and the bridge will be executed in Equatorial Guinea as part of the local content of the Alba B3 gas compression platform project.
With this EPCI contract awarded to Heerema, Marathon and its partners, Noble and GE Petrol, are expected to install the Abla B3 gas compression platform in 2015 for commercial operations to start in 2016.
