Crowley Tug Tanerliq

Crowley Tug Tanerliq

This a photo of the Crowley tug Tanerliq in Port Valdez. The vessel is one of two ocean going ship escort, rescue and oil spill response tugs operated by Crowley Maritime in Prince William Sound. This tractor tug is 155 feet long and currently one the most powerful propulsion tractor tugs in the world. The Tanerliq is equipped with two Voith Schneider Model 36 GII cycloidal propellers and it can generate stopping forces in excess of 300,000 pounds to turn or stop an oil tanker. This tug can direct thrust in any direction and can turn within its own length.
