McDermott International, Inc. (NYSE: MDR) (“McDermott”) announced today that one of its subsidiaries has signed a contract for the design and construction of a new high-spec, highly capable dynamically-positioned combination S-Lay vessel with a 2,000-ton crane. The vessel, tentatively named Derrick Lay Vessel 2000 (“ DLV2000”), will be constructed at Keppel Singmarine in Singapore and is expected to take approx 2.5 years to build. “ DLV2000 is expected to address a market demand we consider to be extremely robust for deepwater pipelines as well as our traditional markets,” said Stephen M. Johnson, Chairman, President and Chief Executive Officer. “A combination heavy lift and deepwater S-Lay pipelay vessel is an important asset for our expanding fleet, focusing on the subsea construction market.” Developed by Keppel’s ship design arm, Marine Technology Development (MTD), DLV2000 is equipped to support advanced deepwater pipelay operations that will allow pipelines to be installed at depths of up to 10,000 feet. An economical vessel transit speed is expected to be 12 knots with a top speed of 14 knots. On completion, the vessel will be able to accommodate up to 400 personnel. DLV2000 is the second new-build vessel currently under construction for the McDermott fleet. In August this year, McDermott signed a contract to build Lay Vessel 108, sister ship to the recently completed subsea construction vessel the Lay Vessel North Ocean 105, a vessel with a high-capacity tower for rigid and flexible pipelay and state-of-the-art marine construction equipment to support the growing rigid reel lay and flexible lay markets.
