Drydocks World wins Hallin Marine contractYard News // June 2, 2010
Drydocks World has confirmed that it has won a contract to build a Compact Semi-Submersible (CSS) vessel for Hallin Marine. The vessel will cost a total of US$110 million.
Designed by STX Canada Marine, the diesel/electric CSS’s primary function is to facilitate repair and maintenance to an existing well, via chemical injection on braided lines, extending perforation tunnels and effectively maximising and extending the productive life of the well.
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.
Denis Welch, Chief Executive Officer of Drydocks World – Southeast Asia, noted that the vessel’s main capability of repair and maintenance is aligned with one of Drydocks World’s main strengths. “It will enable the marine equivalent of keyhole surgery to sub-sea oil production systems,” he said. “This is an exciting first for Drydocks World, also the first of its kind to be manufactured in Batam.
Other features of the 84 metre, 8,200 dwt vessel include an active heave-compensated offshore crane, a single line lifting of SWL (Safe Working Load) 150 tonnes, a complete active heave-compensated, electro-hydraulic Deep Water Lowering System, a five tonnes provision crane and two ROV systems, one launched via the internal moonpool and the other from the vessel’s starboard. The CSS can accommodate up to 152 subsea personnel.
