The efficiency of any shipping vessel can be judged based on its adaptability to changing environmental conditions and its inherent ability to fine-tune its performance accordingly. Most shipping companies are constantly on the look-out for effective and proven methods of reducing the expensive fuel consumption. Trim Optimization is a sure shot way of reducing fuel consumption by increasing propulsion energy efficiency. Based on the loading conditions, the GreenSHIP software calculates the optimum trim value for varying speed ranges.
Generally, ship trim optimization is analyzed with respect to tow-tank testing for specific hullform under even keel conditions. GreenSHIP provides onboard testing tool for dynamically computing trim and sinkage values under different resistance and draft conditions for a given speed which is compared with experimental values to arrive at the optimized trim value for minimum resistance. This resistance which in turn is directly proportional to the power required has a direct bearing on the fuel efficiency and the resultant environmental footprint.
