Abstract

A wind power operation and maintenance ship is one kind of the important equipment to maintain the offshore wind farms. In this paper, the whole structure of operation and maintenance of catamaran is introduced firstly, finite element model of the catamaran and a hydrodynamic calculation model are established, and the whole ship wave load is forecasted subsequently. Considering to the different sea conditions, entering or leaving harbor, full or no load and wave directions, are divided into 7 calculation conditions. The design wave method is used to calculate the wave load of the wind power operation and maintenance ships under various work conditions. Also considering the lateral force and anti-symmetric vertical uniform force under different work conditions, the stress of the entire ship finite element model including wave pressure application and the inertial force application is analyzed subsequently in this paper. According to the relevant requirements of the "domestic sailing ships manufacturing specification", structure strength of the wind power operation and maintenance catamaran is checked and the total strength is evaluated by direct calculation method. The analysis results show that the direct calculation and evaluation is very effective in analyzing the ship structure strength of the wind power operation and maintenance ships, and the effective optimization and improvement reference for the design and development of the kind of ships can be provided from the evaluation results.
