Experience

A key issue in our Arctic research, consulting and design is a profound understanding of the different processes involved in the problem. That requires a good theoretical understanding of the problem in question and experience from execution either in lab or full-scale tailored to fit the target.

The key personnel in ArcISo has a long hands-on experience from a number of surface and airborne surveys in the Arctic oceans. This involves planning and safe execution of the operations involved as well as adaption and performance of data gathering systems.

KV Svalbard employs the jet of its propellers to clear the ice away a key at Svea, Spitsbergen.

SAMS contains a unique numerical model that enables physically based high-fidelity simulations of ice management with the propeller flow of a ship. This model predicts the propeller-flow velocities, calculates the hydrodynamic forces on the ice and integrates the equations of motion of the ice cover, which is represented by an ensemble of rigid bodies (MBD). Data from full-scale tests were used to calibrate the model to simulate the propeller wash effect on breaking and clearing ice away from the key.

Propeller wash used for channel widening, as demonstrated by SAMS.
