The invention relates to a ship navigational speed correction method which comprises preparation before correction and navigational speed correction, and the preparation before correction comprises the steps of preparing a ship model test report, a propeller test report and navigational speed test record data obtained after speed measurement according to a ship offshore speed measurement test method; the navigational speed correction comprises wind analysis, wind correction calculation, wave correction calculation, tide analysis, shallow water correction analysis, correction summarization and navigational speed forecasting. According to the ship speed correction method, the test influence when the ship speed measurement working condition does not accord with the design requirement working condition is avoided, and the test data preciseness is standardized.
本发明涉及一种船舶航速修正方法,包括修正前准备和航速修正,修正前准备包括准备船模试验报告、螺旋桨试验报告以及准备按照船舶海上测速试验方法进行测速后得到的航速试验记录数据,航速修正包括风的分析、风的修正计算、浪的修正计算、潮流分析、浅水修正分析、修正汇总及航速预报。本发明的船舶航速修正方法规避了船舶测速工况与设计要求工况不符时的试验影响,规范试验数据严谨性。
