Design and Analysis of a Sub-Surface Longline Marine Aquaculture Farm for Co-Existence with Offshore Wind Farm

There has been growing interest recently in hybrid installations integrating the offshore wind farm and aquaculture as co-existence while optimizing ocean space use. The marine farms beyond coastal or sheltered areas will require mooring to ensure station-keeping of system during storms. In present work, a sub-surface longline is installed fixed at distance from foundations. designed cultivate oysters multi-compartment bags attached longlines vertically. with cultivating area 200 m × supported by various lines made polypropylene buoys that moored catenary arrangements. Drag coefficients full-scale oyster bag wave current are determined using results basin tests. A lumped model developed validated complete for partial farm. used simulate coupled responses whole site extreme waves currents 50-year return period. strength fatigue designs evaluated against industry standards confirmed comply design requirements.
