ible rig West Mira for operations off Eastern Canada and Greenland. Estimated revenue potential for the contract, including mobilization and performance bonus, is around $1.18 billion for the fve frm years, Seadrill offcials reported. The rig, currently under construction at Hyundai Samho Heavy Industries Co. Ltd. (Samho, South Korea) should be ready to spud its frst well in 2015. Last year, Seadrill locked in some $4 billion in contracts for three ultradeepwater rigs under construction at Samsung Heavy Industries Co. Ltd. (Geoje, South Korea). At least two of the rigs will mobilize to the Gulf of Mexico in 2013. Sigma Offshore Ltd. (Aberdeen, Scotland) contracted with STX Offshore & Shipbuilding Co. Ltd. (Jinhae, South Korea) for construction of a new-generation Bassoe Technology AB (G��teborg, Sweden) BT-UDS ultradeepwater drillship, water depthrated to 12,000 feet. The $672 million rig will be designed for zero discharge to allow operation in environmentally sensitive areas. Delivery is anticipated in late 2015. Sigma also obtained options for four additional BT-UDS drillships at STX. Additionally, Rowan Companies plc (Houston) expects to take delivery of the frst of four ultradeepwater drillships on order at Hyundai Heavy Industries Co. Ltd. (Ulsan, South Korea) in late 2013. The initial rig, the Rowan Renaissance, is designed to drill in water depths up to 12,000 feet. Hyundai will deliver Rowan���s other drillships in 2014 and 2015. New Equipment Slated for Debut Dozens of specialized vessels to serve the offshore oil and gas market will enter the international feet this year. Eastern Shipbuilding Group Inc. (Panama City, Florida) is scheduled to deliver in the summer a second construc- tion vessel, the multipurpose Harvey Deep-Sea, for Harvey Gulf International Marine LLC (New Orleans, Louisiana). The 302-foot vessel will be equipped with a National Oilwell Varco (Houston) active heave-compensated, 165-ton knuckle boom crane capable of lifting and setting 100 tons at depths up to 10,000 feet. Another modern vessel welcomed into the Technip (Paris) feet is the newbuild, medium construction vessel Deep Orient, following completion by Metalships & Docks S.A. (Vigo, Spain). The vessel is dedicated to subsea construction and submarine pipeline installation projects worldwide. Initially, it is expected to work offshore Norway. McDermott International Inc. (Houston), spurred by the upswing in the deepwater subsea construction market, has placed an order for a high-specifcation, combination heavylift and deepwater S-lay pipelay vessel with Keppel Singmarine (Singapore). On completion, the vessel, tentatively named the Derrick Lay Vessel 2000, will be suited to install pipelines in water depths up to 10,000 feet. Another noteworthy project is Shell���s (The Hague, Netherlands) new tension-leg platform (TLP) destined for the Mars feld, considered one of the largest resource basins in the Gulf of Mexico. The hull of the Olympus structure, designated for the Mars B development, was built in South Korea and transported to Ingleside, Texas, where topsides were installed before the TLP departed for its fnal location in Mississippi Canyon offshore Louisiana.
