Proposed Routing Measures for the Aleutian Islands 


UPDATE: On March 13, 2015, the Navigation Communication Search and Rescue Subcommittee of the IMO approved the proposed routing measures and areas to be avoided that were developed as part of the AIRA.  The proposal will move forward to the Marine Safety Committee (MSC) for consideration in June 2015.

In December, the U.S. Coast Guard submitted a paper to the International Maritime Organization (IMO) for the upcoming session of the Subcomittee on Navigation, Communication, and Search & Rescue (NCSR) titled, Establishment of Five Areas to be Avoided in the Region of the Aleutian Islands.

The proposal aims to establish five recommendatory areas to be avoided (ATBAs) in the region of the Alaska Aleutian Islands for vessels making transoceanic voyages through the Bering Sea and North Pacific Ocean adjacent to the islands.  In most areas, the proposed ATBAs extend no further than 50 nautical miles from the shoreline of the islands, with a few areas of greater distance.  The 50 nautical mile buffer allows for repair or time to launch an emergency response effort to a foundering vessel before it runs aground and damages sensitive resources.  It will also reduce the possibility of ships grounding on the shoreline due to negligent navigation.

The identification and establishment of routing measures such as areas to be avoided in the Aleutian Island region has been a recommended risk reduction option of the Aleutian Island Risk Assessment project.  The proposed routing measure will be discussed at the IMO NCSR Subcommittee meeting scheduled the week of March 9-13, 2015 in London, England.
