HOUSTON, TEXAS: As oil prices begin a slow climb, worldwide offshore construction vessel activity appears to be rising slightly alongside it. Derrick pipelay and pipelay barges continue to account for the majority of large construction vessel activity around the world.
Demand for derrick barges dropped in April before moving back to 28 in May out of a total 42 vessels, according to data gathered by ODS- Petrodata. This is down from a peak of 36 working units in October 2008.
Demand for derrick pipelay vessels in April also was up from February and stood at 31 in May. The offshore derrick pipelay fleet consists of about 50 vessels total.
Global pipelay vessel activity has been on the rise in 2009, going from 31 working in February to 37 in May.
New Vessels
Subsea 7 expects to take delivery of newbuild pipelay and construction vessel Seven Pacific in the fourth quarter of 2010. First steel for the Seven Pacific was cut on March 16, and the first units are currently being fabricated at IHC Krimpen Shipyard, near Rotterdam.
The vessel is to be fitted with a 260-ton vertical lay system (VLS) tower, built by Huisman. The VLS will be complete with a 260-ton abandonment and recovery winch with 9,843 feet (3,000 m) of A&R wire.
The vessel will have an overall length of 436 feet (133 m) and a beam of 79 feet (24 m). In addition to the new VLS, Seven Pacific will be equipped with a pipelay suite for installing flexible flowlines and umbilicals, two 1,250-ton underdeck carousels and twin deepwater-rated ROVs.
The investment in the vessel is part of an ongoing capital investment program of over US$1 billion dollars in new assets and equipment which will see eight new vessels joining the existing Subsea 7 fleet between 2007 and 2010.
Drydocks World has delivered offshore multipurpose construction vessel OSA Goliath to Singapore-based Coastline Maritime. The vessel was built at the Drydocks World Pertama shipyard on the island of Batam, Indonesia.
OSA Goliath measures 590 feet (180 m) by 105 feet (32 m) by 39 feet (12 m) and is 22,000 dwt, one of the largest vessels in its class. The vessel is equipped with DP-3 and a crane to install offshore platforms and pipelines in deep waters. In addition to OSA Goliath, Coastline has a similar vessel, Samson, currently under construction at the same shipyard, scheduled for delivery in the first quarter of 2010.
Drydocks World also recently delivered Sea Trucks DP3 pipelay/crane barge Jascon 25. Jascon 25 was built according to the Sea Trucks' hybrid design philosophy and is the third vessel to be delivered in the group's seven vessel new-build pipelay/construction program.
Jascon 25 is a 394-foot (120-m), DP3, pipelay crane vessel with a total thruster power of 12,155 kW, an 800-ton subsea Huisman crane, a 355-man accommodation block, and the capability of laying both flexible and rigid S-lay pipe.
In early April the vessel began work on its first major contract offshore for the Seastream joint venture to install the subsea umbilicals, risers and flowlines (SURF) facilities at the Pyrenees field offshore Northwest Australia.
Recent Contracts
Subsea 7 has been awarded a contract by Petrobras for the Tambau Urugua and P-56 developments in the Santos and Campos basins offshore Brazil. The contract is valued at around US$200 million, with the offshore pipeline installation campaign scheduled for 2010.
Acergy S.A. has been awarded a US$190 million contract from ExxonMobil Corp. affiliate Mobil Producing Nigeria Unlimited (MPN) to revamp three wellhead platforms offshore Nigeria in water depths of up to 115 feet (35 m). The contract includes an MPN-exercisable option for up to five further platforms.
Engineering and offshore work will commence immediately, using derrick lay barge Acergy Orion. Engineering support will be provided in Nigeria by Global Oceon Engineers Nigeria Ltd., Acergy's joint venture with Petrolog Engineering Services.
Global Industries Ltd. has been awarded a project by Shell Offshore Inc. for the decommissioning and abandonment of an eight-pile production platform on Eugene Island Block 331 A in around 250 feet (76 m) of water in the Gulf of Mexico. The platform was damaged by Hurricane Ike last year.
Global is using derrick pipelay barge DLB Hercules, a DP-2 equipped vessel with a crane capable of lifting 2,000 tons, for the project. The 485-foot (148-m) Hercules will carry out decommissioning and abandonment activities, including six major lifts ranging from 400 to 1,800 tons.
Cal Dive International (Oceagorafia) has been awarded a US$58 million contract by Pemex Exploracion y Produccion for the installation of 8.6 miles (14 km) of 20-inch subsea pipeline in the Litoral Tabasco field. The field is in 98 feet (30 m) of water offshore Mexico. The lump sum contract involves 114 total utilization days with a pipelay barge and a derrick barge. Construction began in May.
