    MAC signs newbuild contract for CSS accommodation vessel

    Vessel & ROV News // May 7, 2010

    CSS Accommodator will have a unique Compact Semi-Submersible hullform.

    Marine Asset Corporation (MAC) has announced the recent signing of a newbuild contract for the construction of a 500-man Compact Semi Sub Accommodation Vessel, to be called CSS Accommodator.

    Marine Asset Corporation (MAC), the company established to hold the share interest in the CSS design concept previously held by Minnow Marine Projects Limited (MMPL) - a company sold to the GMMOS Group in the UAE  during Dec 2009.

    When MMPL was sold, the new owners were keen to focus on their core businesses of AHTS, PSVs and crewboats. Hence MMPL’s investment in the CSS did not fit in with the business plan of the new owners and this necessitated the creation of a new company, to hold the already substantial interest  and take the investment forward to the next phase.

    The CSS Concept has taken five years to get to today’s position; from the original concept sketched on A4 paper, to the MODU coded design of today which will change the way the offshore industry works.

    MAC said the contract for construction has been signed and became effective as of 3 May 2010, with a projected delivery of December 2012. The contract has been agreed with the Fujian Mawei Shipyard in China, a shipyard where the shareholders of MAC have to date contracted a total of 16 OSVs over the past 7 years and established an excellent client/customer relationship.

    Said the company: "With in excess of US$2 million spent on the design concept, including detailing, computer modeling, tank testing, close liaison with class, the final  outcome creates a vessel capable to work in any water depth without the need to jack up or set anchors."

    The Compact Semi Submersible hullform provides significantly reduced roll angles compared to a monohull and the DP3 dynamic positioning system  provides an enhanced level of safety during station keeping close to any fixed structures.

    The CSS hull can be used for a variety of roles apart from an accommodation vessel with other variants to follow that can be configured for subsea engineering, diving and ROV duties, in addition to well intervention, and topside construction.

    The CSS at normal operating draft, and arranged in a sub-sea installation configuration, is capable of carrying 1,500 tonnes deck cargo with total cargo deadweight in excess of 3,000 tonnes. The vessel is also capable of being ballasted down so the main hull is immersed thereby increasing the load carrying capability or to reduce trimming effect during large crane operations.

    The accommodation variant will have 230 cabins with the majority being two-man, all with ensuite facilities, and able to accommodate 430 passengers, plus the marine crew of 20 and the 50 hotel and catering staff required to care and feed 500 men. Other facilities will include a gym, cinema, recreation rooms and offices for both clients and crew.

    With a helideck able to support the largest helicopter, crew changes can safely be accommodated offshore. With a 600m2 deck area, 150 tonne telescopic crane and an Active Heave Compensated (AHC) gangway, CSS Accommodator is able to support offshore hook-up and maintenance activity in adverse weather conditions, and so reduce weather downtime.

    CSS Accommodator and other CSS variants have been designed by STX Marine in North America.
