DYNAMIC TENSION ANALYSIS OF A SIMPLE LIFT SYSTEM. A COMPUTER METHOD

There is an increasing need to lift heavy prefabricated structures in the open seas as part of underwater construction projects. The lack of knowledge of maximum tensions in lift systems frequently causes failure of lift lines and equipment damage. This paper, a review of Navy research, presents a method to estimate the probability distribution of peak dynamic line tension induced by waves and a procedure to simulate the time variation of tension. A written computer program performs rapid calculations.
