Application (1 September 2015)

The requirements in this Guide apply to vessels that are designed, equipped and intended to operate in low temperature environments. Application of the requirements in this Guide is optional. When a vessel is designed, equipped, built and surveyed in accordance with this Guide, and when found satisfactory, a classification notation as specified in Subsection 1/3, as appropriate, may be granted.

Those vessels that are designed to meet the requirements of an ice class are to meet Part 6, Chapter 1, "Strengthening for Navigation in Ice" of the ABS Rules for Building and Classing Steel Vessels (Steel Vessel Rules) or other recognized ice class Rules prior to seeking the optional notation discussed in this Guide.

Noting that the regional climatic conditions may vary, this Guide provides notations directly related to the vessel's operating area. For example, for vessels intended to operate in Polar regions (Arctic or Antarctic) on a year-round basis, the requirements contained within the Guide differ from the requirements for a vessel operating in the Polar region only during the local summer period. Similarly, other vessels may be non-ice class yet operate in low temperatures. The Guide also recognizes the fact that the vessels' intended operational profile may vary as some vessels are intended to operate with the assistance of an ice breaker and others are intended to operate independently. Accordingly, the Guide provides requirements addressing the duration of emergency electrical power. This extended emergency power duration is expressed in hours and may be appended to the base optional class notations.

Within this Guide, ABS refers to relevant international regulations and standards that are considered to be applicable. It is recommended that the users of this Guide refer to the most recent text of those regulations and standards when applying the requirements of this Guide, as it is the intent of the Guide to remain consistent with the pertinent international regulations and standards developed by the maritime industry.
