Caesar in transit

Helix Energy Solutions Group expects its new deepwater pipelay vesselCaesar to join the company’s subsea construction fleet in January. The vessel left a Chinese shipyard on Nov. 28, 2009, for transit to the Gulf of Mexico.

Caesar is a DP-2 vessel capable of laying large diameter concrete coated pipelines in shallow water, and up to 24-in. (61-cm) diameter pipelines in deepwater. The vessel’s onboard pipeline manufacturing capability allows for pipelay operations without dedicated onshore infrastructure, an alternative to reeled pipelay vessels in remote areas, according to Helix. The vessel also features a 300-metric ton (331-ton) crane and 450-metric ton (496-ton) A-frame.

Helix also expects delivery of its floating production unitHelix Producer I soon for deployment on the Phoenix field in the GoM in 2Q 2010. Recently the vessel was at Kiewit Offshore Services’ fabrication yard on the Gulf Coast for topsides outfitting and USCG inspections.

In other vessel news, Saipem has contracted Keppel Verolme to repair and modify the semisubmersible pipelay vesselCastoro Sei. Under the contract, Keppel will overhaul four thrusters, install new stinger handling support rails, and repair and modify the vessel’s onboard gantry cranes and fendering system. The company also will complete a hull blasting and painting program.

Work on the vessel is scheduled for completion in 1Q 2010. The vessel then will be deployed for the Nord Stream project, a gas pipeline that will link Russia and the European Union via the Baltic Sea.

String of FPSO contacts awarded

Petrobras Netherlands has awarded Keppel Offshore & Marine a contract for the pre-conversion of the FPSOP-58 for the Campos basin. Keppel Shipyard’s scope of work includes structural and piping renewal, tank coating as well as accommodation refurbishment and upgrading. In 1Q 2011, the vessel will sail to Brazil for the rest of the conversion, which includes topside completion work. P-58 will have production capacity for 180,000 b/d of oil and gas compression capacity for 6 MMcm/d (211.8 MMcf/d). It will operate in Parque das Baleias’ north field in the Campos basin and will be spread moored in 1,400 m (4,593 ft) of water.

Keppel Shipyard also picked up a contract from Emas Offshore Construction and Production, for the conversion of a Suezmax tanker into an FPSO. Upon completion in 1Q 2011, the FPSO will have capacity to produce up to 50,000 b/d of oil and store about 680,000 bbl of oil. The converted FPSO unit will be leased to Premier Oil Vietnam Offshore for the development of the Chim Sao field, offshore southeastern Vietnam.

Eni has awarded Saipem a $1.5-billion contract for the supply and operation of an FPSO. Under the 20-year contract, Saipem will provide FPSO installation and operation management. The vessel will have storage capacity for 700,000 b/d of oil and production capacity for 12,000 b/d of oil. London Marine Consultants designed the external turret mooring system which is being built at Dubai Dry Docks.

For the first eight years of the contract, the FPSO will be installed on the Aquila field in the Adriatic Sea. It will be connected to six risers and three umbilicals. First production is expected in 4Q 2011. During the remaining years of the contract, the FPSO will relocate to another client-designated field.

Hoang Long Joint Operating Co. has contracted Bumi Armada Berhad and Vietsovpetro to deliver an FPSO for the Te Giac Trang field development, offshore Vietnam. Bumi Armada has acquired a Suezmax tanker for the conversion. The contract is for an initial term of seven years and has one-year extensions up to 15 years. It also covers offshore installation, hookup, and commissioning of the FPSO. It will be fitted with production capacity for 45,000 b/d of oil and 1 MMbbl of oil storage.
