Objectives, activities and expected/achieved results

In general, site-specific measurements, in the offshore environment, may not be available, particularly during the early planning phase. Metocean parameters are required to describe wind and wave conditions as well as atmospheric and physical conditions of the ocean environment. In addition, the fatigue assessment of offshore structures is carried out using the Palmgren-Miner rule that relies on the uncertain history and usage. A methodology for evaluating the fatigue performance of offshore platforms based on local approaches, using metocean variability, is to be developed. The service life and history of the decommissioned structures used in the oil and gas industry, to be retrofitted so as to support wind turbines, will be considered. The project team will bring important synergies towards addressing the problem of how to safely and responsibly use or reuse existing sites and systems in place for future offshore wind energy generation.
