Polyurethane Sandwich Panel Systems for Ship Hull Reinforcement
The Royal New Zealand Navy (RNZN) regularly patrol the waters of the Sub- Antarctic Islands and the Southern Ocean in support of the Department of Conservation and Ministry of Primary Industries. Operation in these waters includes the potential presence and threat from ice, and RNZN Offshore Patrol Vessels are protected against ice with a belt of thicker steel about the waterline. Excessive pitch and roll of vessels can however result in thinner and more vulnerable areas of the hull being exposed to sea ice.
