Abstract Global dynamic response models used for the design of wind turbines are largely based on neutral stability, which is not representative real atmospheric conditions. Offshore farms, example, have been seen to experience predominantly unstable conditions, especially at lower speeds. In current work, we use four generation under stable, and stability conditions study low‐frequency content...

Prototype monitoring techniques play an important role in the safety guarantee of mooring systems in marine engineering. In general, the complexities of harsh ocean environmental conditions bring difficulties to the traditional monitoring methods of application, implementation and maintenance. Large amounts of existing mooring systems still lack valid monitoring strategies. In this paper, an un...

The paper presents an optimization system which integrates a parametric design tool, 3D diffraction-radiation analysis and hydrodynamic performance assessment based on short and long term wave statistics. Controlled by formal optimization strategies the system is able to design offshore structure hulls with superior seakeeping qualities. The parametric modeling tool enables the designer to spec...

During the previous OC511 project, state-of-the-art mid-fidelity engineering tools for floating wind systems were found to consistently underpredict nonlinear, low-frequency responses of semisubmersible offshore platforms, leading substantial errors in structural loads because surge and pitch resonance. To examine this underprediction, a coordinated investigation with computational fluid dynami...
