Abu Dhabi Marine Operating Company (Adma-Opco) has awarded South Korea's Hyundai Heavy Industries (HHI) the main contract for the Umm Shaif gas reinjection project in offshore Abu Dhabi (MEED 21:7:06).

The estimated $1,600 million engineering, procurement and construction (EPC) contract will involve the supply and installation of three platforms, 16 subsea pipelines and tie-ins to three existing wellhead towers and the existing Umm Shaif super complex for gas reinjection.

The scheme will take 45 months to complete. HHI is expected to nominate subcontractors for the various construction packages. WorleyParsons of Australia has carried out the front-end engineering and design (FEED) optimisation study.

Umm Shaif, about 150 kilometres northwest of Abu Dhabi city, was the first offshore field to produce crude oil in the emirate in the early 1960s. At present, it has 268 oil wells producing 350,000 barrels a day (MEED 21:7:06).
