Quick Facts

Summary

Regularly the Damen high-speed vessels are equipped with seawater cooled propulsion engines. The exhaust gasses of the engines are going overboard through the side shell. For several reasons this exhaust penetration is cooled with water spray from the cooling water system of the main propulsion engines:

  • Reducing noise;
  • Non-spark guarantee around oil platforms;
  • Protecting paint against heat;
  • Protecting the hull material against the heat;
  • Protecting the exhaust hull one-way flap against heat;
  • Losing the cooling water.
