Guide for Vessels Operating in Low Temperature Environments GUIDE FOR VESSELS OPERATING IN LOW TEMPERATURE ENVIRONMENTS SEPTEMBER 2006 (Updated October 2008 – see next page) American Bureau of Shipping Incorporated by Act of Legislature of the State of New York 1862 Copyright © 2006 American Bureau of Shipping ABS Plaza 16855 Northchase Drive Houston, TX 77060 USA Updates October 2008 consolidation includes: • September 2006 version plus Corrigenda/Editorials Foreword Foreword Vast reserves of gas and oil are expected to be developed in the offshore areas of the Russian Arctic. It is anticipated that European nations and Atlantic states in North America will be the chief consumers of these energy supplies. Year-round carriage by sea – operating in the Baltic, Arctic, and polar environments – will place extreme challenges on the vessels and their crews. To help address these challenges, the ABS Guide for Vessels Operating in Low Temperature Environments has been produced. This Guide provides criteria for the winterization of vessels so as to be suitable for continuous operation in arctic and polar conditions. These criteria supplement those found in Part 6, Chapter 1, “Strengthening for Navigation in Ice” of the ABS Rules for Building and Classing Steel Vessels (Steel Vessel Rules). Where requested by the Owner, vessels designed, equipped, constructed and surveyed in accordance with the requirements of this Guide will be assigned either of the following Cold Climate Operation (CCO) class notations, as appropriate: • CCO for a vessel designed, constructed and surveyed in accordance with requirements in Sections 2 through 6 of this Guide, those being: SECTION 2 Materials, Welds and Coatings SECTION 3 Hull Construction and Equipment SECTION 4 Vessel Systems and Machinery SECTION 5 Safety Systems SECTION 6 Specific Vessel Requirements • CCO+ for a vessel meeting the requirements for CCO notation, as well as Sections 8 and 9 of this Guide, those being: SECTION 8 Crew Considerations SECTION 9 Training and Related Documentation The Guide also contains a series of Appendices that provide supporting information relative to the requirements in Sections 2 through 9. Additional appendices cover: • Weather Conditions of Interest • Guidance Notes on Vessel Operations • Other Reference Sources • A List of Administration Contacts associated with Baltic, Arctic, and Antarctic areas • A List of Meteorological Organization Contacts This Guide becomes effective immediately upon publication.
