Welcome to the Alaska Emergency Towing Systems Project
UPDATE: An updated version of the Alaska ETS Manual is now available, please click HERE.
An Emergency Towing System (ETS) is a pre-staged package of equipment that may be deployed in the event a disabled vessel requires assistance in accessing a place of refuge. A manual that instructs responders on the operations of system as well as procedures for deployment accompanies the system. The system is designed to use vessels of opportunity to assist disabled vessels that are in Alaskan waters. It consists of a lightweight high performance towline, a messenger line used in deploying the towline, a lighted buoy, and chafing gear. These components may be configured to deploy to a disabled ship from the stern of a tugboat or airdropped to the ship’s deck via helicopter.
Within the last decade, several distressed or stricken vessel incidents occurred in or near Alaska. In a few cases these have caused environmental and economic repercussions. In each situation, the vessel was large tramper or cargo type vessels, which generally carry fuel in bottom tanks, thus posing a significant pollution risk in grounding.
The ETS program came into existence following the near grounding of the Salica Frigo on March 9, 2007 in Unalaska Bay. The Mayor of Unalaska convened a Disabled Vessel workgroup to address the possibility of future groundings and to discuss local emergency response solutions. This initial meeting prompted the Emergency Towing System (ETS) workgroup; whose goal was to develop emergency towing capabilities for disabled vessels in the Aleutian Subarea using locally available tugboats in conjunction with ETS equipment stationed in Unalaska.
The project continued over the past five years with a mobilization and deployment exercise conducted annually in Unalaska. In July of 2017 the ETS system was deployed from Unalaska in an emergency situation to assist the disable container vessel Laura Maersk. This equipment, along with the availability of an appropriate sized towing vessel helped avert a possible grounding.
Since the programs origin, it has expanded statewide. The Alaska Department of Environmental Conservation has purchased and stored 10 inch Emergency Towing Systems at the USCG Air Stations in Kodiak, Ketchikan and Sitka, the ADEC Response Warehouse in Anchorage, and the Emergency Response warehouse in Adak. There are also 7 inch Emergency Towing Systems at the Cargo Building in Nome, at the USCG Facility in Cold Bay and at the city dock in Unalaska.
