A salvage tug, known also 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.

Overview

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.

Salvage tugs are used by specialized crew experienced in salvage operations (salvors). Their particular equipment includes:

  • extensive towing provisions and extra tow lines/cables, with provisions for towing from both bow and stern and at irregular angles
  • extra cranes
  • firefighting gear
    • deluge systems
    • hoses
    • nozzles
  • mechanical equipment such as:
    • common mechanical repair parts
    • compressed air gear
    • diving equipment
    • steel for hull patches
    • welding equipment
  • pumps

Modern development

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.
