Model Based Design Optimization of Operational Reliability in Offshore Boom Cranes

Abstract This paper presents a model based approach for design of reliable electro-hydraulic motion control systems for offshore material handling cranes. The approach targets the system engineer and is based on steady-state computations, dynamic time domain simulation and numerical optimization. In general, the modelling takes into account the limited access to component data normally encountered by engineers working with system design. A system model is presented which includes the most important characteristics of both mechanical system and hydraulic components such as the directional control valve and the counterbalance valve. The model is used to optimize the performance of an initial design by minimizing oscillations, maximizing the load range and maintaining operational reliability.
