Gas Turbine System Technician (GS)
GSE = Electrical
GSM = Mechanical


Gas Turbine System Technician are responsible for all gas turbine engines. They maintain propulsion machinery, including gears, shafting and controllable pitch propellers, assigned auxiliary equipment propulsion control systems, electrical and electronic circuitry up to the printed circuit module, and alarm and warning circuitry. They handle administrative tasks related to gas turbine propulsion system operation and maintenance.

-----------------------------------------------------------------------------------

Gas Turbine System Technician (GSE's) operate, repair and perform organizational and intermediate maintenance on electrical components of gas turbine engines, main propulsion machinery, auxiliary equipment, propulsion control systems, and assigned electrical and electronic
circuitry up to the printed circuit and alarm warning circuitry.



The duties performed by GSEs include:

• operating electric plant main and propulsion control equipment;
• locating circuit failures and replacing parts;
• measuring current, voltage and resistance;
• testing for shorts, grounds and continuity;
• testing protective circuitry;
• testing, servicing and replacing batteries;
• performing preventive maintenance on digital data equipment and control and monitoring circuits;
• measuring insulation resistance;
• repairing electrical/electronic cables, wiring and connectors;
• maintaining alarm, indicating and warning systems;
• maintaining and repairing gas turbine engines and auxiliary equipment;
• working with blueprints, schematics and charts;
• performing administrative procedures related to gas turbine propulsion system operation and maintenance;
• performing work area inspections;
• operating standard test equipment;
• stopping engines and checking for proper performance;
• replacing and adjusting operating tolerance of contacts, microswitches, relay switches, pressure switches and temperature switches.

Working Environment
Gas turbine systems technicians usually work in engine rooms or shops that may be hot and noisy aboard many types of modern ships. At shore they may work at major repair or training facilities. Work is physical and analytical (trouble-shooting) for electronic components.

Sea/Shore Rotation for This Rating

• First Sea Tour: 60 months
• First Shore Tour: 36 months
• Second Sea Tour: 60 months
• Second Shore Tour: 36 months
• Third Sea Tour: 48 months
• Third Shore Tour: 36 months
• Fourth Sea Tour: 48 months
• Forth Shore Tour: 36 months

Note: Sea tours and shore tours for sailors that have completed four sea tours will be 36 months at sea followed by 36 months ashore until retirement.

This is a sea-intensive community. Manning conditions at sea may require the need to request sea tour extension or shore tour curtailments to ensure all sea duty billets are filled.
