Navy Hull Maintenance Technician (HT): Definitive Guide (2025)

This guide provides helpful information for those looking to join the Navy as a Hull Maintenance Technician (HT) during the Fiscal Year 2025.

When something breaks on a Navy ship, duct tape won’t fix it. That’s where Hull Maintenance Technicians (HTs) come in.

These Sailors are the welders, metalworkers, and fabricators who repair hull breaches, fix broken pipes, and keep the ship’s structure intact. If it’s metal, HTs can cut it, shape it, weld it, and fix it.

HTs specialize in all aspects of ship repair, working from the belly of the ship to the pilothouse. They maintain their own shop and handle everything from structural repairs to plumbing systems.

If the ship needs it, HTs can build it.

Job Description

Hull Maintenance Technicians (HT) are Navy enlisted Sailors who plan, supervise, and perform various tasks related to the fabrication, installation, maintenance, and repair of shipboard structures, plumbing, sewage, and piping systems.

Hull Maintenance Technicians (HTs) keep the ship’s structure and systems in working order. They don’t just fix things—they weld, fabricate, inspect, and reinforce everything that holds the ship together.

They oversee hull repairs, train personnel, enforce safety procedures, and maintain records. Most HTs serve at sea on ships, but some work at shore stations, sometimes outdoors in harsh weather conditions.

If a ship needs metalwork, pipe fitting, or structural repairs, HTs get it done. They cut, weld, shape, and fix anything made of metal, ensuring the ship stays strong and seaworthy.

With around 2,800 Sailors in the HT rating, they handle everything from plumbing to structural welding—working in shop environments, out on deck, or deep in the ship.

HTs spend about 60% of their career at sea and 40% on shore duty. Whether on ships or in shore stations, they keep Navy structures and systems running.

Fun fact: Did you know they’re nicknamed ‘Snipes‘? Here’s Why…


Specific Responsibilities

HTs perform critical metalwork to keep shipboard structures intact. Their job includes:

  • Repairing valves, plumbing, piping, and marine sanitation systems.
  • Maintaining hulls, decks, and structures through welding, brazing, riveting, and caulking.
  • Inspecting and testing welds with radiological, ultrasonic, and magnetic particle testing equipment.
  • Heat treating and working with different metals—aluminum, steel, copper, brass, iron.
  • Cutting and assembling pipes for ship systems.
  • Repairing ventilation ducts, insulation, and lagging.
  • Fixing boats made of metal, wood, and fiberglass.
  • Managing and maintaining ballast control systems.
  • Overseeing the ship’s Quality Assurance Program.
  • Enforcing safety and security protocols.
  • Maintaining reports and records of repairs and inspections.

Different Roles

Hull Systems Sailors handle shipboard repairs, plumbing, and metalwork. If something breaks—pipes, ventilation, hull plating—they fix it.

Two roles: Maintainers start with hands-on work, while Technicians take on more responsibility and oversight.


Hull Systems Maintainer (Entry-Level, Hands-On Work)

  • Maintain and repair ship surfaces, plumbing, sanitation, and ballast systems.
  • Fabricate metal structures for ship repairs.
  • Inspect and test hull structures and piping.
  • Weld, braze, rivet, and caulk to reinforce and repair.
  • Install and fix valves, piping, and ventilation systems.
  • Work on boats, insulation, and ventilation ducts.
  • Follow Quality Assurance standards to make sure everything holds.

Hull Systems Technician (More Experience, More Responsibility)

  • Does everything a Maintainer does, plus:
  • Construct, inspect, and test shipboard structures.
  • Supervise welding, brazing, and metalwork repairs.
  • Oversee installation and maintenance of valves, piping, and ventilation.
  • Train and guide Maintainers.
  • Ensure all repairs meet Navy standards.

The Job is Tough, But Necessary

Maintainers learn the trade. Technicians step up and lead. Ships don’t stay afloat without them.
