Harbor Ship Assist and Tanker Escort

Valdez, Alaska

In Valdez, Alaska, our personnel and tugs help protect the environment through a contract with Alyeska Pipeline Service Company's Ship Escort/Response Vessel System (SERVS). As part of  this commercial partnership we provide tug escorts for tankers traveling through Prince William Sound to and from the Valdez Marine Terminal, assuring safe passage, even under the most extreme winter weather conditions. We also provide secure docking and undocking operations at the oil product loading terminals.

Our primary tugs located in Alaska are the Alert Class and Prince William Sound Class tugs. These vessels, which feature best-in-class technology, were specifically designed for tanker escort and assist work in the region, and have firefighting, emergency and oil spill response capabilities.

Alyeska Pipeline Service Company's Ship Escort/Response Vessel System (SERVS) is the largest oil spill prevention and response organization in the world, with a mission to prevent oil spills and to protect the environment by providing rapid and effective response services to the Valdez Marine Terminal and Alaska crude oil shippers.
