The front-end engineering and design (feed) for Libya’s planned Mellitah complex expansion project has been completed, according to industry sources.

The client on the project is Mellitah Oil & Gas Company (MOG), a joint venture (JV) of Italy’s Eni and Libya’s National Oil Corporation (NOC).

In November last year, MEED reported that MOG had started the prequalification process for engineering, procurement, installation and construction (EPIC) contracts for the project to develop gas facilities.

It invited companies with ‘extensive experience in offshore projects’ to submit prequalification documents.

The project scope includes offshore structures and the expansion of an onshore gas processing facility.

The whole project has an estimated value of $3bn and is expected to be broken down into four major packages.

The onshore package will include the construction of a new fourth gas processing train, a third condensate train and a third natural gas liquids (NGL) fractionation train.

It will also cover the construction of a fourth sulphur recovery unit (SRU) train and the installation of a hydrogen sulphide (H2S) enrichment unit and sulphur recovery unit.

Two offshore packages cover the structures known as Structure A and Structure E.

The Structure A package covers installing a wellhead platform and drilling eight dry tree wells to handle a peak production of 160 million cubic feet a day (MMcfpd).

It also includes the installation of a 43km multiphase cladded sealine with a diameter of 18” and the modification of an existing platform known as the Sabratha platform.

The Structure E platform includes the installation of a new production platform on Structure E with 20 slots, drilling 18 dry tree wells, drilling three dry tree oil wells and drilling two additional oil wells.

It includes drilling five subsea wells connected to Structure E to handle a peak production of 600 million cubic feet per day and drilling five oil wells.

There is also a subsea pipeline package, including laying carbon steel sealines, installing subsea production systems and installing a topside control system.
