摘要
针对巴拿马运河当局对进入运河船舶限制吃水的要求,阐述了因装货港与运河水密度的差异以及途中油水消耗导致船舶产生吃水与吃水差改变的计算理论,通过合理安排最大吃水和最大载货量、合理预置吃水差、控制横倾和拱垂变形,提出了一种为确保船舶顺利驶入运河在装货港浮态的控制计算方法,经过实践证明,该方法是准确可靠的.
In view of the ship＇s draft restrictions by Panama Canal Authority, this paper explains the calculation principle of the ship＇s draft and trim change owing to the water density difference between the loading port and the Panama Canal,water and oil consumption in the voyage. The author then puts forward a computational method to reach the most reasonable arrangement of the ship＇s maximum draught, maximum cargo volume at the loading port. Practice has proved that this method is accurate and reliable.
