A salvage tug, also known historically as a wrecking tug, is a specialized type of tugboat that is used to rescue ships that are in distress or in danger of sinking, or to salvage ships that 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 numbers around the globe, with higher concentrations near areas with both heavy shipping traffic and hazardous weather conditions.
Their particular equipment includes: The total demand for salvage tug services is significantly down from its peaks in the years around World War II.
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.
