The VG 40 Nozzle has a shorter profile length, but delivers the same forward thrust performance as the conventional 19A Nozzle. At high cruising speeds, the thrust performance of the VG 40 even slightly exceeds that of the 19A nozzle. Another advantage of this nozzle is the improved steering performance.
The VG 40 has a short nozzle profile with a long inlet and the propeller is positioned at the rear of the nozzle.
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.
