析吃水对量油的影响

船舶加油、起租或者还船时都需要准确量油，有时量油所得的油量与通过其他途径所得的油量差距甚大。此文分析了中拱与中垂、水尺艏艉垂线修正以及船舶扭曲变形对量油的影响，通过计算实例分析这些因素对量油造成的误差大小。

Vessel must sound to check the quantity of oil,whenbunkering,delivery and redelivery before and after a period of charter,but the difference between the sounding,and by the other means made ship′s engineers puzzled.this paper discussed the influence upon ship′s hogging and sagging,fore and aft draft mard correction and ship′s distortion,adn also gave some example to interpret such influence.
