The Mooring System Design Of 130kW Floating Tidal Current Power Stations

Tidal energy is a kind of clean and renewable energy. It has many advantages using tidal energy to generate electricity, such as economic, not occupying lands, not being influenced by the climate, not polluting environment. Tidal energy is a kind of new energy with high value and potential in use and will become a very important part in the future new energy. Now, the already running stations have three different forms, they are floating structures, sea-bed piled structures and sit sea-bed structures, such like the70kW tidal current power station. It takes the floating structures, the floating structure is a platform for the generator. To ensure the safety of the station, it is very important to design a feat mooring system.The 130kW tidal current power station is a project, which work together by the Chinese government and the Italy government. In this thesis we give some predictions on the project's mooring system.In order to ensure the safety of the tidal current power stations it is very important to design the mooring system. In this thesis we used SESAM software calculated two different kind tidal current power stations's wave force and motion in the regular waves, and then designed mooring system for the two kind carriers. Two typical carriers, rectangle shape carrier and circle shape carrier, were used to analyses. And also their seakeeping performance was separately calculated when the blades were add to the carriers. The environment forces are calculated according to the formula recommended. The wave drift forces are calculated using spectrum analysis method. And then, we use Mimosa software design the mooring system. The calculation shows that each of the schemes can meet the demand of safety.
