Merwede Shipyard received a contract for the design and construction of a multi pur- pose offshore support vessel for Hornbeck

Offshore Services LLC. The vessel will be built under Yard No. 717 and delivery is scheduled for 3Q 2009.

This MPOCV will be capable of operat- ing globally. However, the Hornbeck

Offshore Services plans to deploy the vessel in its primary operating market, the deep- water and ultra-deepwater Gulf of Mexico.

While this foreign-built vessel cannot qual- ify for Jones Act trade, the Hornbeck intends to U.S.-flag the vessel. Hornbeck

Offshore also has an exclusive four-year option to construct two additional sister vessels based on the same Type-22

MPOCV design at a U.S. shipyard of its choice, which would qualify for domestic coastwise trade under the Jones Act.

This 8,000 dwt vessel will be equipped with two cranes, a helideck, a moon pool and accommodations for 100. The primary crane will have lifting capacity of up to 400 tons in up to 3,000 m of water depth and the secondary crane will provide significant additional lifting capacity. The ship has been designed by Merwede Shipyard in close concert with Hornbeck Offshore

Services and has been based on an enhanced version of the Merwede Type-22 design, Merwede Shipyard's versatile 22 m beam design. It will be a fully Dynamic

Positioned DP3 Multi Purpose Offshore

Construction Vessel, suitable for worldwide operation. news
