Wärtsilä has signed a contract with the German shipowner Jüngerhans, located in Haren (Ems), Germany, to refit two of its vessels with Wärtsilä Slow Steaming Upgrade Kits to cut fuel costs. The 1997-built vessels are equipped with 7-cylinder Wärtsilä RTA62U main engines. In response to over-capacity in the market and a desire to cut overall fuel consumption, during recent months charterers have adjusted both their services and the speed of their ships. Slow steaming has become a way of operating vessels, particularly in the container segment. Slow steaming offers benefits for charterers in terms of substantially reduced fuel consumption and considerable savings in overall ship operation costs.
