Overview

A CG Smart Ship Engineering Control System Equipment mechanical operator and maintenance technician performs organizational level maintenance on pumps, valves, hydraulic systems, fuel systems, lube oil systems, and air systems. The technician also maintains waste heat boilers and LM2500 and Allison gas turbine engines associated with the CG 47 Smart Ship engineering plant and applies engineering administrative program knowledge to work center supervision.

Core Skills

  • LM2500 and Allison gas turbine maintenance
  • Pump, valve, and hydraulic system maintenance
  • Fuel and lube oil system maintenance
  • Waste heat boiler maintenance

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.

Industrial Machinery Mechanics

Organizational-level maintenance of pumps, valves, hydraulics, and lubrication systems transfers directly to maintaining industrial machinery and its components.

How to prepare: Build a maintenance portfolio that maps your pump, valve, and hydraulic repair experience to equipment listed in industrial mechanic job postings.

What the civilian work involves
  • Repair or maintain the operating condition of industrial production or processing machinery or equipment.
  • Repair or replace broken or malfunctioning components of machinery or equipment.
  • Clean, lubricate, or adjust parts, equipment, or machinery.

Stationary Engineers and Boiler Operators

Maintenance of waste heat boilers, pumps, valves, fuel systems, and air systems provides relevant equipment knowledge for stationary plant operations.

How to prepare: Check with the licensing authority in your intended work location to identify the license class for the equipment you would operate and how your Navy experience is evaluated. Some jurisdictions require experience and a written examination, with license classes limiting the type and size of equipment operated without supervision.

What the civilian work involves
  • Operate or tend stationary engines, boilers, and auxiliary equipment, such as pumps, compressors, or air-conditioning equipment, to supply and maintain steam or heat for buildings, marine vessels, or pneumatic tools.
  • Activate valves to maintain required amounts of water in boilers, to adjust supplies of combustion air, and to control the flow of fuel into burners.
  • Observe and interpret readings on gauges, meters, and charts registering various aspects of boiler operation to ensure that boilers are operating properly.
Civilian tools and software (examples)
  • Building management system software
