Overview

A CG-47 Gas Turbine Mechanical Maintenance Technician operates gas turbine main propulsion and electric generating plants aboard CG-47 class ships. The technician performs advanced organizational or intermediate maintenance down to the component level on mechanical systems and auxiliary support systems.

Core Skills

  • Component-level propulsion plant mechanical maintenance
  • Electric generating plant operation and maintenance
  • Auxiliary support system operation and 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.

Power Plant Operators

Operation and component-level mechanical maintenance of shipboard gas turbine generating plants transfer directly to turbine, generator, and auxiliary equipment operation.

How to prepare: Seek a gas-turbine plant operator trainee opening with site-specific instruction in control-board operation and generator output control.

What the civilian work involves
  • Control power generating equipment, including boilers, turbines, generators, or reactors, using control boards or semi-automatic equipment.
  • Monitor power plant equipment and indicators to detect evidence of operating problems.
  • Start or stop generators, auxiliary pumping equipment, turbines, or other power plant equipment as necessary.
Civilian tools and software (examples)
  • Computerized maintenance management system CMMS

Wind Turbine Service Technicians

Component-level maintenance of gas turbine mechanical systems and generating plants provides a foundation for wind turbine mechanical service.

How to prepare: Complete wind-turbine service training covering variable-pitch systems, generator controls, and electrical troubleshooting before targeting mixed mechanical and electrical service work.

What the civilian work involves
  • Troubleshoot or repair mechanical, hydraulic, or electrical malfunctions related to variable pitch systems, variable speed control systems, converter systems, or related components.
  • Diagnose problems involving wind turbine generators or control systems.
  • Start or restart wind turbine generator systems to ensure proper operations.
