When we design new vessels or convert existing vessels many things can be done to reduce the overall energy consumption. First of all we want to reduce the energy needed by optimising the hull, minimising the resistance from rudder and other appendixes, reducing the energy consumption for fans, lightning, accommodation etc.
The next step is to reduce energy losses. Engine and propulsion systems must be considered through optimising propeller-rudder interaction, optimising the propeller for the intended power output, reducing or recovering thermal losses from the engine etc.
To reduce CO2 emissions even further we are looking at other power sources. Wind, waves and the sun is considered "free" energy that can reduce fuel consumption and thereby also the CO2 emissions.
These challenges are what our Ship Design department faces when designing new vessels and/or converting existing ships.
Optimised operation to reduce fuel consumption
From an operational perspective a significant fuel reduction can be achieved by operating the ships efficiently. The way engines and cargo are handled can be optimsed and allow the vessel to sail at optimum speed, trim and draft. Furthermore, efficiently planned routes are important to ensure that the ships sail fully-loaded, and by planning the speed to ensure that the vessels maintain a constant speed from departure to arrival.
These challenges are handled by our crew and by our commercial operators Wallenius Wilhelmsen Logistics (WWL) and EUKOR Car Carriers.
