This article puts forward the main engine hoisting out of the cabin and tooling design of the target ship and proposes the calculation and assessment methods of hull structure during main engine hoisting out of the cabin by combing the relevant standards involved in the safety assessment.In view of the failure or uneven force of multiple slings in the process of alternate use,the article gives the method to determine the accidental load coeffi-cient and compares it with the direct calculation method of finite elements.The article also demonstrates the applica-bility of the theory of single-span beam and three-span beam,which provides a theoretical basis for guiding main en-gine hoisting.
