  • Outline project development including definition of ship main dimensions and capacities; General Arrangement; outline specification; structural drawings; lightweight; hull form; capacities, loading and stability; propulsion, powering and manoeuvrability; study of requirements for alternative LNG fuel; yard contacts
  • Contract design including 3D model and General Arrangement; Machinery Arrangement; gross tonnage calculation; specification; structural principles; lightweight; hull form; tank arrangement and loading conditions; ice model test coordination; stability, intact and damage; powering; electric load analysis
  • 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.

Customer Benefits:

  • 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.

Special Features:

  • 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.
