Floating motion resistant crane for wind turbine installations and maintenance

一种新型抗运动深水重型起重起重机用于海上风力涡轮机安装和维护以及海上石油和天然气工业的可行性研究。该概念允许专业运动稳定的起重机船具有超过1，000吨的起重能力，在超过80米的水深中超过150米的高度，但不依赖于复杂的液压或泵压载系统，如在当前小得多的系统上使用的。它也不会像目前正在使用的几艘大型半潜式起重机船那样造成同样高的成本影响。

The feasibility study of a novel motion resistant deep water, heavy lift crane for use in offshore wind turbine installation and maintenance, as well as the offshore oil and gas industry. The concept allows for a specialist motion stable crane vessel with lifting capacities of over 1,000 tonnes to heights in excess of 150m in water depths of over 80m, but does not rely on the sophisticated hydraulic or pumped ballast systems, as used on current much smaller systems. It would also not have the same high cost implications of the few large semi-submersible crane vessels currently in operation.
