734B Steam Propulsion Maintenance Supervisor

Current service use not established

This code is listed in the directory. Inclusion alone does not confirm current service use.

A Navy Enlisted Classification: a skill designation sailors hold in addition to their rating.

Overview

A Steam Propulsion Maintenance Supervisor oversees organizational level maintenance and conducts onboard maintenance training on conventional propulsion boilers, steam propulsion engines, forced draft blowers, and associated machinery. The supervisor also covers ship service turbine generators, steam plant controls other than automatic boiler controls, auxiliary equipment, valves, and piping, and conducts material inspections, initiates corrective action for abnormal conditions, and inventories required records, technical documentation, special tools, and repair equipment.

Core Skills

  • Maintenance supervision and maintenance training
  • Equipment condition inspection and corrective-action initiation
  • Maintenance records and repair-equipment inventory control

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.

First-Line Supervisors of Mechanics, Installers, and Repairers

Supervising steam-plant maintenance, conducting onboard maintenance training, inspecting equipment condition, and initiating corrective action directly support maintenance supervision.

How to prepare: Build a maintenance-supervision work sample showing how you would assign an equipment inspection, document findings, coordinate corrective action, and verify completion.

What the civilian work involves
  • Inspect, test, and measure completed work, using devices such as hand tools or gauges to verify conformance to standards or repair requirements.
  • Inspect and monitor work areas, examine tools and equipment, and provide employee safety training to prevent, detect, and correct unsafe conditions or violations of procedures and safety rules.
  • Monitor employees' work levels and review work performance.
Civilian tools and software (examples)
  • Microsoft Excel

Maintenance Workers, Machinery

Steam-plant maintenance oversight, equipment inspections, and maintenance-record control provide relevant machinery knowledge for a hands-on maintenance alternative.

How to prepare: Seek supervised, equipment-specific practice in dismantling, reassembling, and replacing parts on the machinery used by a target employer. The verified duties establish supervision rather than personally performed repairs, so assess practical repair proficiency before pursuing this route.

What the civilian work involves
  • Dismantle machines and remove parts for repair, using hand tools, chain falls, jacks, cranes, or hoists.
  • Reassemble machines after the completion of repair or maintenance work.
  • Record production, repair, and machine maintenance information.
Civilian tools and software (examples)
  • Computerized maintenance management system software CMMS
