The Optispec nozzle is a free-hanging steerable nozzle and is specifically developed for ships with a small stern such as self-navigating ships cutter suction dredgers and pushers. With excellent forward and reverse thrust, the Optispec nozzle comes with a fixed rudder blade which can rotate with a 2x35° angle around the propeller.
ApplicationVarious ship types. Especially suited for self-navigating ships cutter suction dredgers and pushers.
Single Weld Spinning Method
Damen Marine Components has developed the Single Weld Spinning Method based on a single weld seam on the inner side of the nozzle. This machine can produce nozzles with an inside diameter ranging from 1,000 mm to 5.3 m outside. Using a completely automated system, the spinning machine can handle stainless steel, duplex, steel and special steel materials.
A nozzle is a sustainable product by definition because it significantly reduces fuel consumption and CO² emissions. The Spinning Weld Method makes the production of the nozzle even more environmentally friendly, since there is less welding and grinding, this saves energy and emissions. In addition, this method saves production time and enhances DMC’s stable price/quality ratio, which makes it more cost efficient.
