摘要
新船型开发和船型优化是船舶工业永恒的主题,目前已由传统的只针对静水性能发展到计入海况的影响。因此,基于静水和波浪条件下的船模试验结果,考虑海况影响,对船舶航线性能进行分析,既是船舶性能评估的重要组成部分,同时也是船舶线型优化效果检验的重要手段,可为船舶所有人和班轮公司呈现出最直观的线型优化效果。以某化学品/油船的原型和改型方案为例,按照上述方法计算分析二者在静水中和目标航线上的耗油量,结果表明改型结果较为理想。
The major concern during development of new ship type and ship form optimization is shifting from the static wa- ter performance to that in real sea conditions for it is the latter reflects the actual operational energy consumption. An straightforward way is to perform the model tests both in static water and with waves, and determine the influence of sea conditions. This is convenient for evaluating a ship design and judging the effect of hull form optimization, and is also a good way of presentation for owners and liner companies to understand the advantage of a hull form. With the above meth- od, the amounts of oil consumption of the prototype and the modification of a chemical/oil tanker on the typical routes are calculated, which proves that the performance of the modification is noticebally improved.
