The power output increases exponentially with increase in wind speed. With larger wind turbines, 66 kV array cables and 220 kV export cables, it is now possible to export up to 420 MW through a single offshore AC cable and transformer. This makes offshore transformer a critical component in ensuring generation availability. Harvesting power offshore requires a state-of-the-art design to combat corrosion. Transport and maintenance offshore come with higher cost and greater risk, designing a maintenance free system is far from reach, however avoiding or replacing components that require frequent maintenance can reduce maintenance hours offshore thereby reducing risks and improve availability Maintenance offshore should ideally be timed when weather and sea conditions are acceptable. Adding condition monitoring system to equipment placed offshore will help in timing maintenance works. Comprehensive data from the condition monitoring system will also help with future improvements. Applying a lean design concept is the key for offshore environment, as it leads to less components requiring maintenance offshore thus helping to achieving a much lighter offshore platform and significant cost savings. 收起
