Drydocks World begins construction of Compact Semi-SubmersibleYard News // November 30, 2010
Derwent is the world's first Compact Semi-Submersible design.
Drydocks World recently held a keel-laying ceremony for the Compact Semi-Submersible (CSS) vessel Derwent, which it is building for Hallin Marine Subsea International Ltd, a Superior Energy Services company, at Drydocks World’s Nanindah shipyard at Batam in Indonesia. The contract for the distinctive project is valued at US$110 million.
Designed by STX Canada Marine the CSS has a semi-submersible hull, making it a cost effective alternative to large DSVs and larger, conventional semi-submersibles in providing subsea services as well as light well interventions.
The primary focus of the vessel, which will be classed by the ABS, will be light well intervention to provide repair and maintenance services.
