NANTONG, CHINA: China's Cosco Shipyard Group started work on its second drilling unit for Norway's Sevan Marine. A steel cutting ceremony on the second Sevan 650 drilling unit was held on Oct. 10 at the Cosco Nantong shipyard.
To date, the Chinese shipyard is contracted to construct the hulls of three Sevan 650 drilling units. The first unit is due for completion by the end of this year or early 2009. The cylinder-shaped Sevan 650 is designed for operations in ultra-deepwater and all ice-free areas, including the Barents Seas. Each of the drilling units is about 85 metres (279 ft) long, 75 metres (246 ft) wide and weighs about 55,350 tonnes (60,885 tons). The drilling unit will be equipped with 10,000 feet (3,048 m) of riser storage, an internal oil storage capacity of up to 150,000 barrels of oil and variable deck load of more than 15,000 tonnes (136,364 tons).
