These cutters, specifically designed for open-water icebreaking, have reinforced hulls, special icebreaking bows, and a system that allows rapid shifting of ballast to increase the effectiveness of their icebreaking. Table 2 contains values of ice thicknesses specified by . Xuelong 2 is a Polar Class (PC) 3 ship (the highest class in the international classification system is PC1 and the lowest is PC7) and is designed to break 1.5-metre thick ice moving at continuous speeds of two to three knots (with icebreaking capability both moving ahead and astern). P-2.2 The Guidelines recognize that this is best achieved by an integrated approach, based on requirements in existing Conventions which cover the design, outfitting, crewing and operation of ships for the conditions which It will be the first deployment of a U.S. Polar-class icebreaker to the Arctic on a non-science mission since August 1994, when the heavy icebreaker Polar … navigation in ice-infested polar waters”2. This Rule Note applies to ships constructed of steel and intended for navigation in ice-infested polar waters, including icebreakers.

As such, Category B ships should be considered ship which are IACS Polar Class PC7 or PC6 or ships with an equivalent level of safety. More information on the IACS Polar Class Rules is offered in Appendix 1. Toda y, safe and responsible business conduct is both a license to operate and a competitive advantage. These Unified Requirements came into effect in … 2.1.4 Polar Class ships may experience in-service structural degradation at an accelerated rate. Definition of IACS Polar Class operation area and season. SPECIAL SERVICE AND TYPE – ADDITIONAL CLASS Ships for navigation in ice JULY 2016. Polar Class vessels have been designed, built, and equipped to allow them to navigate safely in ice-covered waters. Equipped with two twin-engine helicopters, Ultramarine offers a robust portfolio of adventure activities, breathtaking public … The Endeavour Class tankers represent a transition in design from what the shipyards believed the owner needed in the 1970s, to a ship an owner/operator wants for today and for the future. Table 1 provides a list of particulars for the Endeavour Class tankers. Polar security cutter design and features. The Polar Guidelines take into account that the single most significant factor in polar operations is ice by recommending that only those ships with a Polar Class designation or a comparable alternative standard of ice-strengthening appropriate to the anticipated ice conditions should operate in polar ice-covered waters. Table 1. With a complete refurbishment in 2009, the Expedition feels modern and stylish and offers an excellent deck area for wildlife viewing. Machinery Requirements for Polar Class Ships I3.1 Application * The contents of this Chapter apply to main propulsion, steering gear, emergency and essential auxiliary systems essential for the safety of the ship and the survivability of the crew. IMO's International Code for Ships Operating in Polar Waters is mandatory under both the International Convention for the Safety of Life at Sea and the International Convention for the Prevention of Pollution from Ships (MARPOL). Our core competence is to identify, asse ss, and advise on risk management. Structural surveys should, therefore, cover areas identified as being at high risk of accelerated degradation, and areas where physical evidence such as coating breakdown indicates a potential for high wastage rates. NR527 provides requirements for the assignment of the additional class notations POLAR CLASS, one of the service notations icebreaker, and one of the additional service features POLAR CAT. Polar Code ships fall into three categories, Aarnio explains. Ponant’s Class 2 icebreaker is being designed to be a breakthrough–illustration courtesy Ponant 1) A hybrid icebreaker for Ponant I3.2 I3.2.1Drawings and particulars to … Category B: Part I, paragraph 3.3.2.2 of the Code, cross refers, through a foot note, to the IACS Polar Classes. There are several ice classes to choose from (e.g. 1976: Commissioned: WAGB-10 USCGC Polar Star: 1994-aug-22: Deployment: WAGB-11 USCGC Polar Sea to North Pole, in company with CCGS Louis S St Laurent. PSC will feature a proven Polar Class 2 hull design. We are proud to present the latest addition to our fleet of small expedition ships, M/S Balto, named after the leading sled dog of 1925 Nome serum run.She was built for the highest ice class in Rauma, Finland, to serve as a government service vessel in the Baltic sea. The Code acknowledges that polar waters may impose additional demands on ships beyond those normally encountered. Ref. 1.2 The requirements specified in Part II apply to ships with class notation PC1, PC2, PC3, PC4, PC5, PC6, PC7 intended for navigation in ice-infested polar waters.

Gwendy - this time it will happen - Polar Code comes into full force on 1st Jan. 2022. The more efficient 1A super and 1A class ships are able to sail unassisted in … PC3 and other Polar Classes. 1. Icebreaker notation – for ships specially designed to break ice; Winterization – the protection of ship systems from freezing and icing via our Winterized notations; We will help you to select an appropriate ice class, design temperature, polar service temperature, and winterization notation to best suit your planned polar operations. MSC.385 (94). Polar-class icebreakers USCGC Polar Star (WAGB-10), USCGC Polar Sea (WAGB-11) are heavy icebreakers operated by the United States Coast Guard (USCG). Most ice-classed ships Two other ships operating & assume will continue into 2022 are Silver Cloud & RCGS Resolute. P-2.1 The Guidelines aim to promote the safety of navigation and to prevent pollution from ship operations in polar waters. The required Polar Class notation is defined by the ice conditions and the season in which a ship will operate (see Table 1). The design requirements for ice class-es are a minimum speed of 5 knots in the below stated brash ice channels: Ice class Ice thickness 1A Super polar class vessels, PC1 through PC7, 1.0 m and a 0.1 m thick consolidated layer of ice 1A 1.0 m 1B 0.8 m 1C 0.6 m It is anticipated that ice ramming does not take place. for Polar Class Ships (IACS-UR-I3), 2 006 . These coming expedition ships will accommodate only about 200 guests at a time and do it in a style that’s in marked contrast to the rough and ready ice-strengthened ships that specialize in polar cruising today. The International Association of Classification Societies (IACS) Unified Requirements harmonize the rules to be used in the construction of all ships meant to operate in ice-covered waters, including areas where multi-year ice may be present. The Expedition is one of the smallest cruise ships in the Polar regions and offers an intimate experience that allows you to make numerous landings thanks to her small size. It will have the capacity to accommodate 186 members and have an endurance of 90 days. FOREWORD DNV is a global provider of knowledge for managing risk. 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). The 165m LOA, 228-passenger ship will operate in Arctic and Antarctic waters, and will be built to Polar Class 6 – approximately equivalent to the Swedish-Finnish ice class 1ASuper specified for most Baltic ferries. It will have a length of 140.2m, a beam of 26.8m and full load displacement of 22,900t. The IACS Polar Class Rules were formally published in 2008 and were quickly implemented by various classification societies. Kapitan Khlebnikov The 110-passenger Kapitan Khlebnikov is a polar-class icebreaker that combines power and technology with comfort. Category C: are ships which are ice strengthened and non-ice strengthened ships which do not fall into The International Association of Classification Societies (IACS) introduced harmonized rules for ice-going vessels in Polar waters, the Polar Class (PC) Rules, in 2006 [].The structural part of the rules has been revised four times since initial publication. If you want to go see Antarctica or Greenland at a "LOW" price then next year is your last chance. It provides a mandatory framework for ships operating in polar waters. Introduction 1.1.
