Analysis of dynamic tension of mooring lines for berthed container ship

초록

Though Inchon port has a great potential to be a center for an international trade with easy access from sea, air and land, it's role has been below the expectation. The main reason is due to a high tide gradient at the region which limits off loading and loading operation of cargo. This disadvantage has discouraged cargo vessels from berthing the harbors in Inchon. In this paper, a 50,000 dwt container ship being berthed with mooring lines is investigated in offshore container terminal. The dynamic tension of mooring lines is estimated by MORA software. Envieronmental conditions of selected offshroe terminal site are plugged as input data. The mooring line tensions are obtained for various wave frequencies per wave directions. The results demonstrate the change of tensions of lines and the allowable range of safe conditions in berthed mooring.
