This paper presents a numerical model intended to simulate the mooring force and the dynamic response of a moored structure in drifting ice. The mooring lines were explicitly modeled by using a generic cable model with a set of constraint equations providing desired structural properties such as the...

This paper addresses the possible drainage and collapse of closed flexible cages in sea-based fish farming. A closed flexible cage is a floating bag structure containing water that is enclosed from the ambient water. Possible density stratification in typical fjord locations can cause buoyancy drive...

The present paper addresses the seakeeping behavior of a rigid type of floating closed fish cages, with focus on effects of sloshing on the coupled motions and mooring loads. Closed cages have gained much attention recently as a strategy to avoid sea-lice infections in farming of Atlantic salmon. Ho...

The Arctic ocean has been the focus of increasing activities in oil and gas, marine traffic and fisheries as the resources in the Arctic area becomes more attractive for exploitation. There have been several studies on the response of ships and structures in ice covered waters, mainly for oil and ga...

A modified Morison model is presented for calculation of hydrodynamic forces on aquaculture net cages. The model is based on a simple method for conversion of \textit{"screen model force coefficients"} to approximate equivalent directional dependent \textit{Morison coefficients}. The motiv...
