The Research on Driving force and Elements of Main & Side Hulls of Amphibious Maintenance Trimarans in Wind Farm

Abstract

This paper are based on requirements of maintenance on intertidal wind farm in China, Through demonstration, comparison and analysis, it can be determined that the propulsion system on water adopts regular propeller, driving mode on land adopts wheeled mode. For power transmission, mechanical transmission is used while sailing on water and hydraulic transmission is used while driving on land, therefore an affordable, feasible as well as reasonable single-motor propelled system can be determined. Numerical simulation is used to analyze and calculate hydrostatic resistance, pitch and heaving of several amphibious maintenance trimarans which adapt different main, side hull arrangements in regular wave and determine relative position and scheme of main, side hull of amphibious maintenance trimaran. The research results in this paper will provide references for the design and research of amphibious maintenance ship for offshore intertidal wind farms.
