Physical model testing is a key tool in understanding and validating the fundamental relationships between the ice environmental parameters and the dynamics of a DP vessel. The National...

...) is one of the station-keeping methods that can provide mobility and flexibility in marine operations. The presence of sea ice adds complex external forces and moments on the vessel which must be managed by the DP system. This paper presents an icevaning control algorithm of the Arctic DP system. To make...

...Abstract Abstract This paper presents an overview of a five year research and development project aiming to develop dynamic positioning (DP) system technologies specifically for ice-rich environments. It has been initiated by the Centre for Marine Simulation (CMS) at the Fisheries and Marine...

... characteristics (floe size, floe thickness, inclusion of brash ice and small ice pieces, ice drift speed and direction) and DP system (gain set-ups). Over the years, many engineers have been using numerical and experimental tools to assess the effect of these parameters. More recently, a comprehensive series...

.... The test set-up combines the already existing knowledge for moored structures with the recently developed DP system for model tests in ice. The DP system is a result of the recent research project DYPIC ( www.dypic.eu ) and is operating in a new designed mode which only controls the heading of the vessel...

A case of combined mooring and thruster-assisted mooring is also examined. The additional contribution of the thrusters (or control of the DP system) is shown to somewhat reduce...
