Drydocks World recently held a keel laying ceremony for a state-of-the-art Compact Semi-Submersible (CSS) vessel. „The Derwent‟ is being built for integrated energy services provider 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.
Drydocks World and Maritime World Chairman Khamis Juma Buamim stated that while subsea production systems ranged in complexity they were highly reliable and specialized vessels that had to be commercially viable and efficient. He explained that one of the most outstanding aspects of the CSS being built at the Drydocks yard were its low costs coupled with its excellent project load capacity.
Designed by STX Canada Marine Inc the CSS vessel has a semi-submersible style hull making it a cost effective alternative to large Diving Support Vessels (DSV) and traditional semi-submersibles in providing subsea services as well as light well interventions.
“The CSS is an exceptional vessel and is capable of working in any water depth. We have prior experience in this field and this new project represents confidence in our ability to produce innovative vessels. Drydocks World has established a track record of building specialised niche
vessels and we remain committed to providing seamless, efficient and cost-effective services to our customers worldwide,” said Buamim.
The primary focus of the vessel, which will be classified by the American Bureau of Shipping, will be light well intervention to provide repair and maintenance services to an existing offshore well and sub-sea oil production systems support.
The CSS is equipped with four fixed-pitch Azimuth thruster units and full DP-3 capacity, which enables automatic as well as manual dynamic positioning/heading control in harsh environmental conditions, and has a multiple inherent fail-safe capability.
The 84-metre, 8200dwt vessel has an active offshore crane, a single line lifting of 150 tonnes SWL (Safe Working Load), a complete active heave-compensated, electro-hydraulic Deep Water Lowering System, a five tonnes provision crane and two deepwater Remotely Operated Vehicles. The CSS can accommodate up to 152 sub-sea team members.
