Offshore energy, whether oil production or wind, seems to move in the same stages. Early offshore drilling was in shallow water using jack-up rigs sitting on the bottom. Now much of offshore oil production is from floating rigs, drilling in deep water. Likewise, the first offshore wind turbines were mounted on pedestals fixed to the sea floor. Wind technology may be moving into deeper water. In September of 2009, we posted about Hywind, the first the first full-scale floating wind turbine in the North Sea off South-west Norway. Now the US and the UK have agreed to work together to develop floating wind turbines operating in waters as deep as 500 feet. From the agreement announced yesterday:
In the UK, the Energy Technologies Institute is currently in the process of commissioning a £25m offshore wind floating system demonstrator….In the US, the Department of Energy have recently announced a $180m funding opportunity for up to four Advanced Technology Demonstration Projects in US waters – which potentially could include a floating wind demonstration.
