Activation of the Operating Guidelines for Ice Conditions in Upper Cook Inlet, effective December 4, 2024

In consultation with SWAPA, the US Coast Guard COTP has activated Ice Guidelines for Upper Cook Inlet (Anchorage).

This is for upper Cook Inlet only. Please see activation letter and Guidelines attached.

UPPER COOK INLET GUIDELINES

North of 60° 45’ N latitude (East -West Forelands)

WHILE MOORED AT FACILITIES IN UPPER COOK INLET:

A. SELF-PROPELLED VESSEL OPERATIONS

1. Vessels should maintain “underway” watches in both engineering spaces and on the bridge when ice conditions threaten a vessel’s mooring arrangement.

2. While these guidelines are in effect, steam (or other heated medium, not including air) should be continuously delivered to both the primary and secondary sea chests.

3. Engines, generators, propulsion systems, and winches should be in a status to ensure the most expeditious means of mitigating ice conditions by relieving strain on mooring lines, getting the vessel underway, or both as appropriate. A sufficient number of additional mooring lines should also be immediately available.
