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: For the ship design system E4 a universal crane model was developed. With the help of this model the design of crane vessels and cranes can be harmonised better and lifting operations can be analysed more precisely. The model is able to handle any type of cranes which are used in the shipping and offshore industry and provides the input for every simulations method within E4 which needs to consider crane operations. Special focus was given on keeping a common user interface both for the designer of a crane vessel and the planning engineer for lifting operations independently of the type and functionalities of the crane. Such a universal crane model has not been implemented in any other ship design software until now. In this article the motivation for the development of the model is described together with the requirements for a universal crane model. The principle of the model explained and its functionality is demonstrated in several examples.
