Vroon orders innovative safety standby vesselsVessel & ROV News // April 6, 2006
Vroon's new SSvs are of an innovative new design, the Damen 4711.
Vroon Offshore BV and Damen Shipyards Gorinchem have signed a contract for the design and construction of four Safety Standby Vessels of the Damen 4711 design.
The contract was won against intense competition from Spanish, Portuguese and Chinese yards and follows an order of two 72m PSVs from the same client in December 2005.
The innovative design of the vessels safety standby was developed for Vroon Offshore BV in response to what the company calls "the booming standby vessel market in the North Sea area," and focusses on simplicity, functionality and crew comfort.
The result is a completely new concept for a 47m long design with the rescue zone and Fast Rescue Craft located amidships and the wheelhouse 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. The fore ship is fully dedicated to the survivors and is clearly separated from the crew accommodation.
The propulsion system consists of a single 1,325kW main engine, driving a fixed pitch propeller through a reverse reduction gear box. A diesel-electric system for a 300kW 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 bow thruster load with 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 (part of the Damen Shipyards Group), with the hulls being built in Poland.
The delivery of the first vessel is scheduled for the summer of 2007. The following three vessels will be delivered at three-monthly intervals.
