Thus, cargo ship traffic in the Arctic presently is mostly regional, not trans-Arctic.

UK working groupDNV GL 2013IMO Polar GL 2013Identified HAZARDS, used as basis for the developmentThe Polar Code considers hazards which may lead to elevated levels of risk due to increased probability of occurrence, more severe consequences, or both: it may affect hull structure, stability characteristics, machinery systems, navigation, the outdoor working environment, maintenance and emergency preparedness tasks, and malfunction of safety equipment and systems; topside icing, with potential reduction of stability and equipment functionality; temperature as it affects the working environment and human performance, maintenance and emergency preparedness tasks, material properties and equipment efficiency, survival time and performance of safety equipment and systems; periods of darknessor daylight as it may affect navigation and human performance; latitude as it affects navigation systems, communication systems and the quality of ice imagery information; possible lack of accurate and complete hydrographic data and information, reduced availability of navigational aids and seamarks with increased potential for groundings compounded by remoteness, limited readily deployable SARfacilities, delays in emergency response and limited communications capability, with the potential to affect incident response; lack of ship crew experience in polar operations, with potential for human error; lack of suitable emergency response equipment, with the potential for limiting the effectiveness of mitigation measures; changing and severe weather conditions, with the potential for escalation of incidents; and environmentwith respect to sensitivity to harmful substances and other environmental impacts and its need for longer restoration. risk level within polar waters may differ depending on the geographical location, time of the year with respect to daylight, ice-coverage, etc. Thus, the mitigating measures required to address the above specific hazards may vary within polar waters and may be different in Arctic and Antarctic waters19DNV GL 2013Safety - depending on type of operation OSV operations -> normally several vessels operating together Destination shipping -> experience Transit one of the routes -> IB assistance or independent, NSR or NWP Cruise, large vessels ??
