Trim optimization of reefer vessels
, 2014 The influence of trim on the fuel consumption of reefer ships have been investigated. The project have been carried out at NYKCool AB, a ship operator of reefer vessels. In the speed range 17-19 knots and deadweight percentage of approximately 70% the smallest calculated resistance is obtained for bow trims which are between -1 m and -2 m depending on

Trim Loss Optimization by an Improved Differential Evolution [PDF]
Mathematical Problems in Engineering, 2013 The “trim loss problem” (TLP) is one of the most challenging problems in context of optimization research. It aims at determining the optimal cutting pattern of a number of items of various lengths from a stock of standard size material to meet the customers’ demands that the wastage due to trim loss is minimized.
