Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Structural Metal Fabricators and Fitters

HT experience fabricating, installing, repairing, and inspecting shipboard structures transfers directly to structural fabrication and fitting work.

How to prepare: Have a fabrication employer assess your documented structural work against its drawing-reading, layout, fitting, and welding tasks to identify any targeted practice needed.

What the civilian work involves
  • Verify conformance of workpieces to specifications, using squares, rulers, and measuring tapes.
  • Study engineering drawings and blueprints to determine materials requirements and task sequences.
  • Position, align, fit, and weld parts to form complete units or subunits, following blueprints and layout specifications, and using jigs, welding torches, and hand tools.

Plumbers, Pipefitters, and Steamfitters

HT installation, maintenance, repair, and inspection of plumbing, sewage, and piping systems closely match civilian pipe-trade work.

How to prepare: Ask the licensing board and an apprenticeship sponsor in your intended work location to assess your existing qualifications and documented HT experience for licensing eligibility or apprenticeship placement. Most states and some localities license plumbers, often requiring 2 to 5 years of experience and an exam for independent work; some states also license pipefitters or steamfitters, and gas-line work may require a separate license.

What the civilian work involves
  • Assemble pipe sections, tubing, or fittings, using couplings, clamps, screws, bolts, cement, plastic solvent, caulking, or soldering, brazing, or welding equipment.
  • Locate and mark the position of pipe installations, connections, passage holes, or fixtures in structures, using measuring instruments such as rulers or levels.
  • Cut, thread, or hammer pipes to specifications, using tools such as saws, cutting torches, pipe threaders, or pipe benders.

Maintenance and Repair Workers, General

HT maintenance and repair of shipboard structures and plumbing systems provide a direct foundation for the structural and plumbing portions of general maintenance work.

How to prepare: Compare your documented repair experience with a target facility's maintenance duties and seek a practical assessment of any unfamiliar machinery before choosing additional training.

What the civilian work involves
  • Repair machines, equipment, or structures, using tools such as hammers, hoists, saws, drills, wrenches, or equipment such as precision measuring instruments or electrical or electronic testing devices.

Career Growth

  • Certified Maintenance and Reliability Professionals (CMRP)

    Develop and demonstrate broader maintenance and reliability knowledge when expanding beyond hands-on structural and plumbing repairs.

    Eligibility and preparation: SMRP sets no education or work-experience minimum; candidates must not have sat for the exam within the preceding six months.
