DNV focuses on additional risks when moving ship operations from worldwide trade to cold-climate areas. The extreme conditions with ice and very low temperatures will put stricter requirements to the ships, equipment and crew than normally required. The polar areas are defined as particular sensitive, and the vision of zero discharge is commonly accepted. The purpose of DNV’s focus on Cold Climate is, in addition to development and maintenance of Rules for ships operating in Polar areas, to provide services and to share experience and knowledge beyond the typical classification product to ensure safe operation in the Polar waters.
Purpose
Estimation of ship loads and motions due to operation in the Polar areas
Identification of ice feature failure loads and characteristics
Variation of ice loads with season and operational areas
Estimation of safe speed for operation in ice
Icing of ships
Design of ship for specific purposes or ice breaking capabilities
Modes of operating ships in ice
Analysis of availability of Polar areas for shipping operations
Benefits
Safe design for operation in Polar areas
