About 2000 wind turbines per year shall be installed and commissioned in the German North Sea by the year 2020. The construction of these facilities place special demands on the installation vessels. In order to address the specific aspects of crane operations in the offshore wind market, we develop a software tool for the design of crane ships, planning, and safety analysis of offshore crane operations. The tool is integrated in the ship design platform E4. By using this optimized product development tool, engineering offices and shipyards from Germany will be able to configure, develop and build innovative heavy-lift vessels and crane ships. Within the research project we develop numerical tools and methods which will enable the assessment of complex crane operations at sea under adverse environmental conditions. There is a lack of essential design principles for these vessel, because the successful planning of crane operations is a key element in the offshore segment. These fundamentals can be created using the developed methods, and thus it is possible to be able to include these aspects in the design of vessels. click here for further information.

Abstract: This paper describes a new method to obtain passive and stable state-space models for radiation force computation. These models can substitute the convolution integrals in the Cummins Equation and thus reduce the computational effort of radiation force calculation by about one magnitude. In contrast to existing substitution methods, there no longer exists a trade-off between accuracy, stability and passivity of the obtained model, which allows the highly accurate radiation force calculation of floating systems with multiple degrees-of-freedom.
