... and turbines. Nowadays, one key challenge is designing optimum mooring arrangements for large-scale FOWT. A meta-heuristic solution is recommended to solve a complex optimization problem, such as the mooring arrangement of a floating wind turbine. Among these, the Evolutionary Algorithms (EA) use mechanisms...

... Abstract The mooring system of a floating offshore wind turbine (FOWT) impacts both the capital and operational expenses. The future success of floating offshore wind is, therefore, dependent on finding optimum mooring system designs from the wide field of possibilities. This paper introduces...

... Abstract Mooring systems in offshore applications primarily use chains to connect floaters to anchors. However, these systems are vulnerable to corrosion and fatigue, leading to failures. The offshore renewable energy industry will benefit from cost-effective condition monitoring...

... Abstract The safety of offshore floating units highly depends on the platform’s station keeping capability, which is provided by its mooring system. Mooring chain fatigue failures have recently aroused the interest of the technical community in developing new design and monitoring methodologies...

... Abstract A hybrid mooring system with steel chains and synthetic fiber ropes for offshore floating wind turbines is attractive for several reasons, including lower material costs. However, the degradation of synthetic fiber ropes over long-term use has not been fully verified. In this study...

... Abstract During the recent research studies Digital Twin (DT) simulation models for Structural Health Monitoring (SHM) based on data-driven mode have been developed, which can provide accurate simulation and prediction of mooring forces of Floating Offshore Wind Turbines (FOWTs). However...

... floats, two configurations of wire rope mooring systems and various membrane pre-tensions were simulated in the time domain. The mooring response and elastic behavior of the structure under various environmental load such as current and wave were also investigated. The wind loading is neglected...

... a jump start in the readiness of floating wind technologies. Compared with bottom-fixed offshore wind turbines, semi-submersible FOWT has many advantages, among different floater types, in economic efficiency as offshore wind farms go to deeper water. This paper summarizes the design of a mooring system...

... Abstract Recent runout accidents of GPS buoy demand more robust mooring system in harsh environment. The mooring with steep wave configuration formed by intermediate buoys could be a candidate of the robust mooring system. However, the steep wave mooring (SWM) could have some risk...

... Abstract DNV is currently running a Joint Industry Project, “NorMoor JIP”, which is now approaching the end of phase 3. In this phase the fatigue limit state (FLS) of mooring line studless chains for permanent units has got the main attention. Phases 1 and 2 covered the ultimate (ULS...

... engineer’s toolbox. Two decades ago, model tests were performed on a seemingly simple geometry in the form of a rectangular barge with horizontal skirts fitted at its keel. The hull was held in place via a soft horizontal mooring system for simplicity and with a view to concentrating on the hydrodynamics...

... Abstract Analytical, experimental and computational models have historically been heavily simplified, linearized, and otherwise reduced. This paper shows how such model reductions eliminate the fundamental geometric changes that determine real behavior in cables, strings, moorings, guys...

... Abstract Mooring is one of the key components of a floating offshore wind turbine since the mooring rupture may lead to the total loss of one or even several turbines in a farm. Even if a large experience in moorings of floating bodies was gained in the oil & gas industry, the renewable...
