IHIMU开发设计的低晃动海上风力发电浮体（点击放大） 日本IHI MARINE UMITED公司（总部：东京，以下简称IHIMU）完成了海上稳定性出色的低晃动型海上风力发电浮体的概念设计。风力发电浮体是漂浮在海上的风力发电装置的基座。设计输出功率为2.5MW级，也可用于更大型的风力发电装置。
据介绍，此次设计的浮体采用了IHIMU与IHI共同开发的“两点无波形状（COB：Column Outer Belt）”技术、以及东京大学研究生院新领域创成科学研究科教授铃木英之开发的“晃动减轻鳍片”技术和最先进的模拟技术。通过采用这些技术，可减轻浮体在海上的晃动程度。其效果通过约1／50尺寸的水槽实验得到了证实。
其他主要特点有：（1）通过将吃水深控制在50m左右，能够以设置状态（垂直状态）进行建造和运输。因此，在施工及维护方面便利，可扩大能够设置的海域范围；（2）还可满足风力发电装置的大型化需求，并可将风压负载下的倾斜降至最小限度。IHIMU将以实现浮体式海上风力发电为目标，继续推进研发和探讨详细设计。（记者：高田 宪一）

Type floating offshore wind power development for low mobility in the successful collaboration with the reduced mobility of Tokyo -
2011.04.19
IHI Marine United Inc. (IHIMU, Location: Minato-ku, Tokyo, President: Shigeru Makoto 蔵原) is pleased to announce the University of Tokyo (Professor, Graduate School of Frontier Sciences, Suzuki Hideyuki University) in collaboration with low developed a floating offshore wind sway, completed the conceptual design.
This floating, which is expected for large installations at home and abroad to reduce greenhouse gas emissions will be used for offshore wind power offshore.
The main features are as follows.
IHI - and so far have been developed IHIMU the "no wave shape point 2 (COB: Column Outer Belt)" along with the application of reduction techniques, such as agitation, held by the University of Tokyo, "Finn reduction upset," cutting-edge technology By applying simulation technology to reduce the floating body sway.
- By reducing the draft to about 50m, set state (state V) improved maintenance and construction to allow the construction of transportation, and implementation can be installed to expand the area.
Support wind power generator - an increasingly large slope stability by minimizing wind load and (stability) holds.
- So far, installation of equipment for wind waves in the waters around Japan have all year, it was an issue of maintenance work can be done in days, floating in the newly developed "COB" to combine work on the ship and offshore unit By providing a mechanism can be implemented to increase the number of days.
* To see the effect of technology to reduce agitation, about 1 / 50 IHI-scale tank experiments were conducted in R & D Headquarters in the tank, see the effect.
The newly developed floating 2.5MW power plant is intended to be a class can be tailored to support wind power generator is now even larger.
IHIMU future, toward the realization of a floating offshore wind power, will continue research and development, we will proceed to a detailed design study. 减摇鳍对于造船企业并不陌生，但风电企业是隔行的，所以不可能开发。
风电并不是一 独立行业，而是与铁道车辆和造船行业技术相近的行业，所以独立风电企业前途堪忧。 很有创意啊！
