Abstract Selecting a proper lifting method for wreck removal is one of the most important procedures when planning a salvage operation. For this, both the safety and economy should be considered to prevent accidents and reduce time and cost. We propose an evaluation and verification method considering the safety and economy. A simulation based on multibody dynamics is used to assess the safety of the lifting method. In particular, we implemented a model to calculate the contact and friction of the wire when lifting the ship to simulate the wire-wrapping method. Next, we proposed a method of estimating the total salvage cost and an economic evaluation was obtained by comparing the results of various lifting methods. We attempted to estimate the time and cost of salvage quantitatively using expert consultation results and calculations. Finally, the proposed safety assessment and economic evaluation method were applied to various lifting methods.
