St-Laurent. In May 1996, an "Ad-Hoc Group to establish Unified Requirements for Polar Ships (AHG/PSR)" was established with one working group concentrating on the structural requirements and another working on machinery-related issues. Although the rules generally require the ships to have suitable hull form and sufficient propulsion power to operate independently and at continuous speed in ice conditions corresponding to their Polar Class,[1] the ice-going capability requirements of the vessel are not clearly defined in terms of speed or ice thickness. Estimated to cost approximately $210m, the vessel is currently under construction at ASMAR Shipyards’ facility in Talcahuano, Chile. The steel-cutting ceremony of the polar ship was held in May 2017.

Ships with sufficient power and strength to undertake "aggressive operations in ice-covered waters", such as escort and ice management operations, can be assigned an additional notation "Icebreaker". [4] However, unlike the Baltic ice classes intended for operation only in first-year sea ice, even the lowest Polar Classes consider the possibility of encountering multi-year ice ("old ice inclusions"). The vessel features external equipment such as echo sounders, sonars, and a global positioning system (GPS) for use in SAR missions. We offer our US Coast Guard Polar class icebreaker (WAGB) models in several poplular size/scale offerings for easy ordering and selection. It will also be used to provide logistical support, including transportation of personnel, aviation fuel, and oil to the country’s Antarctic bases. These Guidelines apply to ships constructed of steel and intended for navigation in polar ice-covered waters. All longitudinal regions except the bow are further divided vertically into "bottom", "lower" and "icebelt" regions. For each region, a design ice load is calculated based on the dimensions, hull geometry and ice class of the vessel. CCGS Polar Class 8. We use cookies to ensure that we give you the best experience on our website. The United States had just one operational polar-class icebreaker. For example, propeller-ice interaction should be taken into account in the propeller design, cooling systems and sea water inlets should be designed to work also in ice-covered waters, and the ballast tanks should be provided with effective means of preventing freezing. The design scenario used to determine the ice loads is a glancing impact with ice.[1]. The descriptions given in the rules are intended to guide owners, designers and administrations in selecting the appropriate Polar Class to match the intended voyage or service of the vessel. Safety equipment will also be carried to protect the crew in low-temperature operations.

Polar-class icebreakers USCGC Polar Star (WAGB-10), USCGC Polar Sea (WAGB-11) are heavy icebreakers operated by the United States Coast Guard (USCG). The development of the Polar Class rules began in the 1990s with an international effort to harmonize the requirements for marine operations in the polar waters in order to protect life, property and the environment. However, since the vessel also has a class notation Icebreaker(+) and operates as an escort icebreaker in difficult ice conditions, she has additional structural strengthening in … It will also incorporate microbiological, macrobiological, as well as chemical laboratories, instruments and sample collection equipment to support advanced scientific studies and research activities. [2], The IACS has established seven different Polar Class notations, ranging from PC 1 (highest) to PC 7 (lowest), with each level corresponding to operational capability and strength of the vessel.

Diefenbaker, is designed to ice class PC 2 Icebreaker(+). Her ice class, Polar Class 4, is intended for vessels operating year-round in thick first-year ice which may include old ice inclusions. The vessel will be capable of operating in extremely low temperatures up to -30°C. Seven Polar Classes are defined in the rules, ranging from PC 1 for year-round operation in all polar waters to PC 7 for summer and autumn operation in thin first-year ice.[1]. Polar 8, Canada's projected 38,000 ton Arctic Class 8 icebreaker, would have been the largest non-nuclear icebreaker in the world.

[13][14], The ice class assigned to a ship by a classification society based on the Unified Requirements for Polar Class Ships, This article is about ice class. When developing the upper and lower boundaries for the Polar Classes, it was agreed that the highest Polar Class vessels (PC 1) should be capable of operating safely anywhere in the Arctic or the Antarctic waters at any time of the year while the lower boundary was set to existing tonnage operating during the summer season, most of which followed the Baltic ice classes with some upgrades and additions. Ships can be assigned one of seven Polar Classes (PC) ranging from PC 1 for year-round operation in all polar waters to PC 7 for summer and autumn operation in thin first-year ice based on the Unified Requirements for Polar Class Ships developed by the International Association of Classification Societies (IACS). [1], The lowest Polar Classes (PC 6 and PC 7) are roughly equivalent to the two highest Finnish-Swedish ice classes (1A Super and 1A, respectively). Despite this it continues to suffer from mechanical decay and requires expensive repairs on an ongoing basis.
