Extreme Low Temperature Training
摘要
Vessels operating in low temperature environments are exposed to a number of unique circumstances. Weather conditions are poor and navigation charts may be unreliable or not reflect current conditions. Shipboard polar ice charts should be updated weekly upon processing of satellite images. Local ice conditions may differ significantly from those depicted on charts. Maintaining manoeuvrability for the avoidance of locally heavy ice conditions is an important consideration when using ice charts at the route planning level, and communication systems and navigational aids present challenges to mariners.
