Overview

An LPD 17 class diesel engine technician operates and performs advanced organizational or intermediate maintenance on main propulsion diesel engines and ship service generator diesel engines. The technician maintains these engines and their related systems to the component level.

Core Skills

  • Component-level maintenance of marine propulsion diesel engines
  • Ship service diesel generator 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.

Bus and Truck Mechanics and Diesel Engine Specialists

Advanced component-level maintenance of propulsion and generator diesel engines transfers directly to the diesel-engine repair side of this occupation.

How to prepare: Complete hands-on training in civilian diesel diagnostics using Cummins INSITE, focusing initially on engine-specialist positions rather than whole-vehicle repair.

What the civilian work involves
  • Use handtools, such as screwdrivers, pliers, wrenches, pressure gauges, or precision instruments, as well as power tools, such as pneumatic wrenches, lathes, welding equipment, or jacks and hoists.
  • Attach test instruments to equipment, and read dials and gauges to diagnose malfunctions.
Civilian tools and software (examples)
  • Cummins INSITE
  • Computerized maintenance management system software CMMS

Motorboat Mechanics and Service Technicians

Operating and maintaining shipboard propulsion diesel engines provides relevant marine engine experience for smaller-vessel service work.

How to prepare: Take a hands-on service course for the small-vessel engine models used by a target marine repair shop.

What the civilian work involves
  • Start motors and monitor performance for signs of malfunctioning, such as smoke, excessive vibration, or misfiring.
  • Repair engine mechanical equipment, such as power tilts, bilge pumps, or power take-offs.
  • Perform routine engine maintenance on motorboats, such as changing oil and filters.
Civilian tools and software (examples)
  • Engine diagnostic scanners

Industrial Machinery Mechanics

Component-level maintenance of ship propulsion and generator diesel engines provides a mechanical repair foundation for industrial equipment maintenance.

How to prepare: Seek supervised shop practice in disassembling and reassembling the production machinery used by a target employer.

What the civilian work involves
  • Repair or replace broken or malfunctioning components of machinery or equipment.
  • Disassemble machinery or equipment to remove parts and make repairs.
  • Reassemble equipment after completion of inspections, testing, or repairs.
