Technip has won in the race for the contract to develop the Bahr Essalam phase 2 (SEN, 32/15) project in the Central Mediterranean Sea offshore Libya.

The natural gas field development, which is operated by Mellitah Oil & Gas, a consortium between National Oil Corp. and ENI North Africa, will be tied back to the Sabratha platform, which is situated about 110 km off the Libyan coast in a water depth of about 190 m.

The overall scope of work will see Technip carry out the overall design, detailed engineering and deliver the project management as well as procurement, installation, tie-ins, precommissioning and commissioning. This will be associated with the provision of a gas gathering system, which includes production pipelines, a subsea isolation valve and umbilicals as well as extensive diving and installation campaigns.

It also will include modifications to the Sabratha platform topsides. All offshore mobilisations will be undertaken from Malta.

Offshore installation is scheduled for second-half 2017 through to second-half 2018. A range of vessels from the group’s fleet will be involved, including the Deep Energy pipelay vessel, the Deep Arctic diving support vessel and the G1200 S-Lay vessel.

Phase 2 of the development will cover the delivery of gas output from two new wells from the C Central A area and 10 wells from the C East area to the Sabratha platform.

Gas and condensate production will be partially treated on the platform and then sent onshore to the Mellitah plant for final treatment. Current production from the Bahr Essalam Phase 1

project is running at 27.3 MMcm/d, while Phase 2 is expected to add production of 12.6 MMcm/d. Total cost of the overall project is put at $2 billion.

Development of the Eastern area covers 10 wells divided into two cluster manifolds, ECE and MCE, with five wells each.

These will be connected to existing risers and J-tubes on the Sabratha platform. ECE will be a 13.2-km tieback and MCE a 9.6-km tieback.

A new cluster in C Central Area A for two wells will be tied back 10.7 km to Sabratha, while a third well will be tied back 5 km to a dedicated preinstalled in-line tee.

Subsea facilities in this area include a pipeline end manifold collecting production from wells CC-16 and CC-17, subsea christmas trees for the wells, a subsea production control system, an 8-in. 10.7-km production line and a control umbilical.
