Damen Delivers Patrol Boat

On August 24, Damen Shipyards Gorinchem delivered the Damen Stan Patrol 2005 Zilvermeeuw to the Dutch Customs. This is the third vessel of this type, following the delivery of the Kokmeeuw and Mantelmeeuw, which were delivered to the Dutch Customs in 2004. The construction of the aluminium hull and deckhouse of Zilvermeeuw was subcontracted. The complete outfitting was carried out at Damen Shipyards Gorinchem. The twin-screw propulsion system consists of two MAN D 2840 LE401 main engines producting 1206 bkW at 2,300 rpm, driving two Promarin FP propellers through a pair of ZF 550A gears. Although the ship will sail at relatively slow patrol speeds most of the time, it can achieve a maximum speed of 23.5 knots. Special features include a hydraulic collapsible mast, for low air-draft; aydraulic Palfinger PC 2300 MBV1 deck crane; and a Duarry SB Cat 400 RIB-type tender During the design and construction of the vessel, much attention was given to minimise vibration and noise levels. For this purpose, not only the engines but also the complete deckhouse is fitted on flexible mounts. Apart from this, floating floors are used throughout the vessel. As a result, the noise levels are remarkably low for an aluminium high-speed patrol vessel: 61 dB(A) in the deckhouse at the maximum speed of 23.5 knots.
