| Abstract | The most important thing when planning a salvage is choosing a proper lifting method. An appropriate method of lifting is considering safety and economy. In this study, we proposed the evaluation and verification method considering safety and economy. Simulation based on multi-body dynamics is used for assessing the safety of the lifting method. In particular, we implemented a module to calculate the contact and friction force of the wire when lifting the ship, so we can simulate the wire wrapping method. In addition, the dynamic lifting force is calculated by considering various external influences. Next, we propose a method of estimating the salvage cost and economic evaluation is obtained by comparing the results of various lifting methods. To estimate the cost of lifting the ship, the salvage operation is divided into four stages and the required time is calculated. For calculating the cost of lifting, lifting materials are divided into equipment, craft, personnel, and material. In this study, we tried to estimate the time and cost of salvage quantitatively using expert consultation results and calculations. Finally, the safety assessment and economic evaluation method proposed in this study are applied to various lifting methods. |
