Adma-Opco is looking to tender the contract on an engineering, procurement and construction (EPC) basis. However, it has informed companies that if there is not enough interest in the EPC model, it will look at an EPC management (EPCM) type of contract.

The contract, valued at $300 million-400 million, will involve the supply and installation of three platforms, subsea pipelines and tie-ins, and modifications to three existing wellhead towers. Under the plan, the compression platform will be located two kilometres from the existing Umm Shaif super complex (USSC) and connected to an accommodation platform. The third new platform, accommodating an oil separation unit will be connected to the existing USSC.

The new facilities will have capacity to dehydrate and inject 600 million cubic feet a day (cf/d) of sour gas into the Arab C and D reservoirs to improve oil reservoir pressure. They will also be able to handle 305,000 barrels a day (b/d) of oil, 1,000 million cf/d of associated gas and 125,000 b/d of water.

Australia's Worley is due to complete by September a front-end engineering and design (FEED) optimisation study, which has looked at a major reduction in the original scope of work and project costs (MEED 13:2:04).
