ABS classes Vroon PSVsVessel & ROV News // June 3, 2013
ABS has been selected to class two Ulstein-designed PX121-type platform supply vessels (PSVs) that were ordered by Vroon Offshore Services (VOS) and will be built at China’s COSCO Guangdong Shipyard.
The PX121 design features the Ulstein X-BOW, an advanced bow design that improves handling in rough sea and expands the vessel’s operational window to include more harsh weather environments. The shape of the bow also reduces power consumption and improves fuel efficiency.
“Owners and operators with OSVs working in harsh environments select these types of designs to realize operational efficiency benefits and to better cope with harsh conditions,” says Mike Sano, ABS Energy Project Development Principal Engineer.
“Being selected to class today’s high-technology modern designs demonstrates the trust our clients have in ABS and showcases the use of the recently released ABS Rules for Building and Classing Offshore Support Vessels.”
The 4,200 tonne dwt PSVs will be 83.4m long, with a beam of 18m and have a maximum draught of 6.7m and a design draught of 6m with 850 m˛ of cargo deck area, a deck load capacity of 2,300 tonnes and a top speed of 14.5 knots.
ABS will provide technical classification services to verify that the vessels comply with proposed notations.
Vroon expects the two vessels, which are scheduled for delivery in 2015, to work offshore Europe and in the North Sea.
