The maritime-shipping industry has also been forced to contend with the key issues of energy efficiency and sustainability. Optimizing the trim of a ship is a good way to achieve lasting reductions in fuel consumption. In fact, trim optimization has been an object of investigation since the 1990s. Back then, forward-thinking German shipowners were using models in towing tests designed to determine the trim that produced the lowest resistance as a ship moved through water. These tests showed that in many cases a slightly lower forward draft yielded the ideal trim. Based on these findings, INTERSCHALT added a ballast optimization tool to its MACS3 loading computer system. However, over the next 15 years interest in this special module declined because the costs for conducting the associated towing tests proved to be too high. Significant fuel saving by trim optimization "Determining the optimum trim is one thing; being able to practically apply these findings in actual ship operation is... [More]
