The increasing demand for fish has led many aquaculture installation owners to move from inshore to further offshore where space allows for expanded production. In addition, pollution, rising costs and intense competition for shoreline real estate create significant incentives for positioning aquaculture installations offshore.

To address this growing trend, ABS has published the Guide for Building and Classing Aquaculture Installationsand is applicable to several types of installations including spar-type, column-stabilized type, ship-shape floating fish farming installation as well as non-buoyant fish farming installation.

The Guide provides class requirements for the design, construction, installation and survey of non-self-propelled, sited aquaculture installations. Specifically, the Guide addresses three major elements: the hull structure, the mooring system or foundation, and onboard machinery, equipment and systems that are not part of the aquaculture systems.  Applicable vessels that meet the class requirements included in the guide are eligible to receive the notations Fish Farm Installation, Manned or Fish Farm Installation, Unmanned, accordingly.

Additionally, ABS has also issued the Guide for Building and Classing Aquaculture Service Vessels which focuses on the class requirements for aquaculture service vessels, including support vessels, pellet carriers, live and refrigerated fish carriers, harvest, factory and processing vessels.  Applicable vessels that meet the class requirements included in the Guide are eligible to receive the notations ASV-Support, ASV-Fish Pellet or ASV-Live Fish, accordingly.

ABS has been involved in several aquaculture installation projects with particular consideration of the unique characteristic of the installation with regards to global performance, structure, mooring and stability.
