The findings knew that the ships collision is a type of an act of tort , its liability asks to recompense is looks carefully the state of fault to decide , generally may divide into the force majeure or the unknown cause collision , the mutual fault of both sides collision and so on , because if the force majeure or the unknown cause collision , undertake voluntarily by the victim , if an error of the side undertakes the damage compensate responsibility by the inflicter , when if both sides have mutually to cause its faults , basically it depends on the fault to share , but if it's unable to judge the proportion then the average to share is necessary.

研究结果得知，船舶碰撞为一典型之侵权行为，其责任求偿乃端视过失型态而定，一般可分为不可抗力或不明原因之碰撞、单方过失碰撞及双方互有过失碰撞等，而若因不可抗力或不明原因之碰撞者，由受害人自行承担，若纯为一方之过失者则由加害者承担损害赔偿责任，若因双方互有过失所造成时，原则上依过失程度分担，但若无法判定比例时则平均分担。
