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.
