Subsea 7 Wins Work Offshore Angola on the Tombua and Landana Fields

Subsea 7

Subsea 7 has been awarded a significant contract offshore Angola by Cabinda Gulf Oil Company Limited, a wholly owned subsidiary of Chevron Corporation. The EPIC (Engineering, Procurement, Installation and Commissioning) work scope, with a value of approximately US $290 million, is for the development of the Tombua and Landana fields in Block 14, offshore the Province of Cabinda in Angola. The project is to tie-back a subsea well center, located approximately 9 km from the new Tombua Landana Compliant Production Tower. Subsea 7 will fabricate and install steel pipelines, flowline jumpers, connectors and umbilicals as well as install operator supplied equipment such as manifolds and distribution units. The Tombua and Landana fields are in water depths of between 270 and 370 meters.

The fabrication of the pipelines will be executed on the existing spoolbase operated by Subsea7's affiliate company Sevenseas Angola. For the offshore execution, Subsea 7 will use either the Skandi Navica or its new pipelay vessel, Seven Oceans along with a construction support vessel from its fleet. The offshore work will be performed in two phases, with final completion in the first quarter of 2009. Engineering and project support will be undertaken from Subsea 7's Houston office. Sevenseas Angola will engage a range of local Angolan contractors, including in country supply of pipe line insulation coatings, welding of pipelines, fabrication of pipeline end termination (PLET) structures, and other local services. As such, Subsea 7 will ensure a high local Angolan content and meet its objective to increase local value on each new project.

Jan Willem van der Graaf, Subsea 7's Vice President – West Africa, commented, "We are very pleased that Chevron has awarded us this contract, which follows our successful completion of the Lobito Tomboco project. The Tombua Landana project is our third major pipeline project in Angola. With this continuous work for our site and vessels we can fulfil our ambition to work with local Angolan staff, invest further in-country on developing existing or new assets and become a well established Angolan Contractor".
