Economic Benefits
Trim optimization has significant economic benefits in terms of fuel savings. These economic benefits will vary from one ship size and type to others. It should be emphasized that even small trim changes can have a large impact on vessel performance. To reduce fuel consumption and emissions, trim needs to be optimized before and during a ship’s voyage through a proper loading of the ship or use of ballast water in order to achieve a floating position that consumes the least propulsion power. Ships normally record their trim before the voyage by directly reading the draft marks (MariEMS 2017).
