MATCHING SPEEDS AND FUEL EFFICIENCY
Design of a new cruise ship is based on the routing between the ship ’ s home berth and the intended destination ports . The itineraries may , for instance , include longer transits to warmer waters and visiting some islands in these waters . Therefore , the speed and power demand of the ship ’ s engines are liable to vary considerably along the route .
In conventional designs , diesel electric power plants run at a constant speed . To match the power production with the actual demand , generators can be called online or dis engaged .
“
Up to 2 000 tons of fuel can be saved annually by engine speed optimisation .

A modern cruise ship is typically equipped with four to six main engines . On the grounds of fuel economy , it is preferable to run the ship at certain speeds . In turn , some speed ranges should be avoided as they require the power plant to run at poor efficiency .
Routing and power plant design can be matched so that the speed profile leads to optimised fuel con sumption .
However , the problem here is that a cruise ship is rarely utilised on the same route over the ship ’ s entire life-cycle . Moving to another route might require completely different speeds which would perhaps again lead to poor fuel economy .
