J. Ray McDermott will undertake fabrication and installation work for the P-61 Tension Leg Wellhead Platform (TLWP) in more than 3,871 feet of water, for the Papa Terra Joint Venture, consisting of Petrobras (operator) and Chevron.
The overall P-61 project — comprising design, engineering, construction, transportation, installation, and a three-year limited operations contract — was awarded to FloaTEC Singapore Pte Ltd (FloaTEC Singapore), a joint venture between Keppel FELS Ltd (Keppel FELS) and J. Ray. Almost all the work will be carried out through the combined resources of Keppel FELS, J. Ray and FloaTEC LLC (FloaTEC), the US-based joint venture company that will perform global engineering and basic design work.
The TLWP will be constructed by Keppel’s BrasFELS yard in Angra dos Reis, Brazil. J. Ray will fabricate the tendons, temporary buoyancy modules and piles at J. Ray’s Morgan City facility in Louisiana, USA. The FloaTEC Singapore JV will supply risers, well systems and tendon components, and J. Ray will install the facility in the Papa-Terra field using the Derrick Barge 50, its specialized deepwater construction vessel. J. Ray will also provide topsides engineering, procurement services and integration across all interfaces along with FloaTEC and Keppel FELS.
Tendon sections will be manufactured at J. Ray’s multi-joint fabrication facility at Morgan City where heavy-wall steel catenary riser systems have been successfully delivered for other deepwater projects.
The topsides and hull will be integrated at a near shore site and following subsequent hook-up and commissioning work at quay side, the TLWP will be wet-towed to the offshore installation site to hook-up to pre-installed tendons. J. Ray will pre-install the anchor piles and tendons at the offshore installation site prior to the arrival of the TLWP. The integrated TLWP will be positioned over the tendons and subsequently connected and tensioned to ensure stability. The project is targeted for completion by mid 2013.
