Procurement support
Support in yard process to shipbuilding contract
Development of wider shore link-spans in all intended harbours of new (wider) vessel (the 1Alink-spans needed to facilitate also existing narrower vessels). Simulation of vessels berthing shore link-spans was done in 3D.

Reliable support and partner in challenging development task. Concept was changed several times due to customer input and information on how to adapt the vessel for the intended route.

Very challenging ice conditions on the intended route (shallow sea will freeze almost to bottom) so a lot of effort was put on determining the propulsion power needed for winter/summer conditions and developing and engine and propulsion concept that would be fuel efficient in all seasons.
