Safety Standby Vessel Order for Damen

Posted on April 5, 2006

A contract was recently signed between Vroon Offshore B.V. and Damen Shipyards Gorinchem for the design and construction of four Safety Standby Vessels 4711. The contract follows the order of two 72 m Platform Supply Vessels from the same client in December 2005. The main part of Vroon's Offshore vessels are being operated by Vroon Offshore Services in Den Helder and find employment in the North Sea, although the vessels can be employed anywhere. Vroon Offshore Services operates vessel types such as safety standby (NOGEPA/UKOOA), platform supply, diving support, maintenance, anchor handling tug/supply vessels etc. The four new building safety standby vessels will be partly additional and partly to replace the current safety standby fleet of 13 vessels.

The innovative design of the vessels was developed for Vroon Offshore B.V. in answer to the booming Standby Vessel market in the North Sea area and has been focused on simplicity, functionality and crew comfort. The result is a completely new concept for a 47m long and 11m wide Safety Standby Vessel. The rescue zone and Fast Rescue Crafts are located amidships and the wheelhouse is situated just aft of the rescue zone, resulting in an optimal view from the control stations in the bridge wings. The crew accommodation is located aft of the rescue zone for optimal comfort in seaway. The fore ship is fully dedicated to the survivors and is clearly separated from the crew accommodation.

The propulsion system consists of one 1325 kW main engine, driving a fixed pitch propeller through a reverse reduction gear box. A Diesel-electric system for a 300 kW retractable azimuth bow thruster is provided as a secondary propulsion system and for standby operations. This propulsion concept is optimized for fuel consumption by enabling one generator set to take the full hotel load and restricted bow thruster load, with still sufficient capacity for station keeping in standby operations in fair to moderate weather conditions.

The vessels will be built by Maaskant Shipyards in Stellendam, The Netherlands (a full member of the Damen Shipyards Group), with the hulls being built in Poland, a much proven building concept for the Damen Shipyards Group. The delivery of the first vessel is scheduled for the summer 2007. The following 3 vessels will be delivered with each 3 months interval.
