Establishments in this class assist marine vessels with navigation, docking, undocking, and harbor maneuvering — including harbor tugboat operations, licensed marine piloting services, vessel traffic reporting, and marine salvage. Workers typically operate on or around vessels in active waterways, and operations often involve direct physical contact with large commercial ships, barges, and other watercraft.
Questions to investigate
- What specific services are provided — piloting, harbor tugs, vessel traffic reporting, salvage, or a combination?
- How many vessels are owned or operated, and what are their types, ages, and current survey status?
- What is the trading area — harbor only, coastal, or offshore/international waters?
- Is any marine salvage work performed, and if so, what types of vessels and cargo are involved?
