With fish farming moving from onshore to offshore, a novel fish pen design is needed. The scoping study “Review of Fish Pen Designs and Mooring Systems” by C. M. Wang et al. (2020) provided an overview of current challenges and future design opportunities for offshore fish pens.

Based on that, two new design schemes called SeaFisher and SeaDipper evolved. Submitted as a patent application, they reduce the wave load by either elevating or submerging the main parts of the structure.

Linked with the other BECRC programs, this project proposal will develop the SeaDipper and SeaFisher conceptually further to create safer, more efficient and affordable offshore fish pen structures.

Two major industry partners (Tassal Group and Huon Aquaculture) with broad operational expertise will participate and co-select the most promising concepts of the SeaFisher and SeaDipper during this first phase before the concepts will be improved and tested in detail, prototyped, and commercialised in the subsequent two phases.
