영문 초록

Most of the domestic car ferries departing from Jeju Port in Korea were replaced through the construction of new ships or the introduction of new used ships starting in 2018 after the Sewol Ferry accident. Amid this trend of ship replacement, the size of passenger ship has also become larger than in the past to increase passenger sales and cargo transportation profits, but the passenger ship berth configuration at Jeju Port have not improved significantly. In this study, the current status of passenger ships at Jeju Port was investigated, and a mooring safety assessment was conducted on car ferries exceeding the design berth capacity of the pier. Risk factors of the target ship were identified through mooring safety assessment. Through the sensitivity analysis of each improvement plan, a plan to improve mooring configuration was proposed and its effect was confirmed. As a result, the in case of Arion Jeju which is berthed at No. 2 pier, improvement plan scenario case 1 to 4 from the operator’s perspective did not secure the mooring safety due to the problem of exceeding maximum traction force with the size of the mooring post. However in case of scenario case 5 of the improvement plan through the additional installation of High Height Bitt, it was analyzed that a load of about 23% or less of the breaking strength of all lines acts on the mooring line and the load of 44% or less of the maximum traction force of the mooring post acts that the mooring safety was evaluated to be secured. The results of this study are expected to be used as reference materials for the establishment of safe passenger ship berth mooring configuration and the development of guidelines for mooring a car ferry.
