Carbon Trust researches offshore structural issues

WORLDWIDE: The Carbon Trust is to undertake a research and development study into how to tackle the greater-than-expected structural issues experienced at some offshore wind farms.

The trust said it is seeking a contractor to complete the Maximising Lifetime Asset Integrity study.

This research will cover not only increased maintenance and repair activities that push up operational expenditure, but also concern that structures will not reach their assumed lifetime.

This study aims to identify which issues are having the greatest impact on the structural integrity of constructions and will test supported foundations, jackets and monopiles.

It will identify the best way to mitigate potential issues and look at remedial actions that could be taken to address these problems.

The trust is also looking for offshore wind farm consultancy services to study which gravity base structures could most reduce offshore wind costs, lifted or floated.

"Gravity base structures, in terms of potential cost reduction, have very promising foundations concepts for wind turbine generation in deeper water sites competing against steel jacket structures for large offshore wind farms," it said in a statement.
