Force Technology has been working intensively with trim optimisation tests for almost last 10 years. Focus has primarily been put on the possible power savings and exhaust gases reduction. This paper describes the trim optimisation process for a large cargo vessel. The physics behind changed propulsive power is described and the analyses in order to elaborate the optimum trimmed conditions are presented. Different methods for prediction of required power in trimmed conditions are presented and results are compared against each other. The methods with their advantages and disadvantages are discussed. On the basis of power prediction, a trim guidance with dedicated SeaTrim® software for ship master is made and presented.
