Numerical Modelling of a Mussel Line System by Means of Lumped-Mass Approach

Journal of Marine Science and Engineering, 2019
This paper describes a numerical model to simulate the behavior of a mussel longline system, subjected to environmental loads such as waves and current. The mussel line system consists of an anchor, a mooring chain, a long backbone line, mussel collector

Dynamic HVDC export cables and floating substation for shallow water floating wind

Journal of Physics, Conference Series
This paper presents the design and assessment of a dynamic 320 kV HVDC export cable for shallow-water floating offshore wind (FOW), evaluated under harsh metocean conditions representative of the Celtic Sea, which was deliberately selected to stress test

Time Domain Ultimate Buckling Limit State Assessment of a 15MW FOWT Substructure Using FLOWStress

Volume 5: Ocean Renewable Energy
Some codes such as OpenFAST, OrcaFlex, and BLADED that have been used popularly for integrated load analyses (ILAs) of floating offshore wind turbines (FOWTs) solve the equation of motions at the center of mass, hence substructure should be assumed as ...
