10 ST | September 2018 www.sea-technology.com F loating wind turbines (FOWTs) are growing in cred- ibility among researchers, developers and investors. Hywind Scotland, the world's first floating wind farm, demonstrates the technology is ready to accelerate the renewable energy mix. There is much overlap in the de- sign, fabrication and installation of the platform, moor- ings and anchors used in oil and gas and floating wind systems. We know from the oil and gas sector that en- suring mooring system reliability is a challenge. In re- cent decades, several billion-pound failure incidents of mooring systems have occurred. For example, a spate of brittle fracture failures in the drilling industry neces- sitated the need for improved requirements for chain manufacturing processes in the 1980s. The proliferation of permanently moored floating production units (FPUs) led to the discovery of out-of-plane bending fatigue in the mid-2000s—a previously unknown cause of failure. To combat this, the oil and gas sector has steadily in- vested to further develop guidance aimed at enhancing mooring system reliability. There are two aspects to this: Mooring for Offshore Wind Applications of Oil, Gas Technology for a Low-Carbon Future By Dr. Alex Argyros • Francois-Xavier Sireta Floating wind foundation types.
