A salvage tug is a specialized type of tugboat which is used to rescue ships which are in distress or in danger of sinking, or to salvage ships which have already sunk or run aground.
Few tugboats have ever been truly fully dedicated to salvage work; most of the time, salvage tugs operate towing barges, platforms, ships, or performing other utility tugboat work.
Tugs fitted out for salvage are found in small quantities around the globe, with higher concentrations near areas with both heavy shipping traffic and hazardous weather conditions.
Salvage tugs are used by specialized crew experienced in salvage operations (salvors). Their particular equipment includes:
The total demand for salvage tug services is significantly down from its peaks in the years around World War II.
The increasing sensitivity of societies and legal systems to environmental damage and the increasing size of ships has to some extent offset the decline in the number of salvage operations undertaken. Accidents such as major oil tanker groundings or sinkings may require extensive salvage efforts to try to minimize the environmental damage such as that caused by the Exxon Valdez oil spill, or the Amoco Cadiz and Torrey Canyon disasters.
