Patrol Vessel Grote Stern Delivered
The Grote Stern, a patrol vessel built by Damen Shipyards, was delivered in late September. The vessel will be employed by the Surveillance Service in the District of Rotterdam.
The vessel features an aluminum hull and superstructure, designed in accordance with DNV standards. The 60.7-ft. (18.5-m) vessel is powered by two MTU/Mercedes diesel engines, which allow the vessel to attain a speed of 25 knots. The engines are mounted in-line with the shafts and four-blade fixed pitch propellers. The propellers and rudders are installed in special tunnels to achieve a high propulsion efficiency. These tunnels have a positive influence in reducing vibrations and noise levels. The ZF reverse/reduction gearboxes are directly coupled to the main engines, which are flexibly mounted.
