The first ship with nozzle cooling has been delivered to the customer.

Cooling Nozzle


The cooling nozzle has been developed because the size of main engines of various ship types are reducing, which means the power of the engines is squeezed. This results in the need for more cooling capacity.

By applying the cooling nozzle, the water flow rate coming from the propeller is constantly high. This is specifically when the main engines run full power.

The cooling nozzle innovation guarantees high efficiency cooling and is highly applicable to ships with a high bollard pull.



  • Higher water flow rate coming from the propeller
  • Excellent heat transfer


Various vessel types. Especially suited for tugs and workboats.

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.


  • Cost efficient
  • Smoother nozzle surface
  • Reduced fuel consumption and CO² emissions
  • Efficient production process
