AbstractThis paper presents results from two related studies of wave loading on fish cages. The first was an in-situ measurement of wave induced mooring line forces on a full-scale conventional salmon cage measured over a 6-week period. Results from this study are presented and statistically analyzed revealing that wave action was not the primary environmental load. The second study is a model scale evaluation of wave-induced loads and motions in an experimental cage concept, which incorporated an articulated deck, a lower damping ring and a variety of mooring configurations. Some comparisons are made between the data gathered in both studies. Conclusions are also drawn about the effectiveness of alternate mooring arrangements and some problems with out-of phase motions between the deck and the lower damping ring.
