Hull Strength Analysis of the Anchor Handling Towing Ship based on Wave Loads Direct Calculation Method

With the development of ocean engineering technology,it becomes increasingly fierce on offshore oil and gas resources competition. As one kind of necessary auxiliary ships in the offshore oil exploitation field, the Anchor Handling Towing Ship(AHTS) has been committed to to develop further all over the world. Firstly, the wave-induced loads are calculated using the scatter diagram of working areas by using random wave theory. Secondly, hull structure strength is analysed and verified. The study can provide a valuable reference for the ship design and construction.
