A new generation of offshore structures

Research output: Chapter in Book/Report/Conference proceedingConference contribution book


Current offshore structural design guidance, knowhow and standards are based on Oil & Gas industry research conducted mainly in the 1970s and 1980s. Since that time, European Steel Fabricators have made significant advances in volume manufacturing processes and these along with improvements in steel performance, Quality Assurance and advanced structural analysis techniques promise lower cost, reliable steel structures for use in Wind, Wave and Tidal power. In addition, there are several fundamental differences between conventional offshore Oil & Gas structures and those used in the emerging offshore renewable energy sector, not least; the very large volume of similar structures, the unmanned nature of installations and the cost margins involved. These combined with improved capabilities of modern offshore fabrication and design demand a fresh perspective on the Guidance and Standards available to developers. This paper reviews the guidance available and identifies in particular fabrication, material improvement techniques and modelling approaches that may be useful in the design, operation and maintenance of Offshore Structures for Renewable Energy.
