Ice impact: Operating a vessel in Arctic waters puts special demands on hull coatings, which must be resilient to impacts from ice while also miniminsing friction
Temperatures on Arctic routes can drop to below -50℃, which means that even in fair weather atmospheric icing from sea-spray will seriously damage a ship's superstructure or destabilise it. Seas can be covered with pack ice, often 3m thick, and vessels are under constant threat from drifting ice floes and icebergs. This means that vessels must be reinforced with thicker steel plates, stiffeners and frames in the defined ice band region of the hull, which usually extends 1m above and below the ship's waterline. Hull coatings also affect a ship's performance in ice. We knowthat vessels need, as a minimum, an abrasion-and impact-resistant coating on the ice band area of the outer hull. Generally, Hempel recommends that the whole vertical bottom area of the vessel is painted because ice damage can be more extensive.
