Ship Rider

DMEC’s Ship Riders are licensed engineers. They work aboard the deployed Littoral Combat Ships—in port and at sea. The Ship Rider is the senior hull mechanical and electrical (HM&E) technical advisor for the ship’s force.

His primary responsibilities include: train the crew on main propulsion and auxiliary plant operation and deck equipment operations; perform preventative maintenance and emergent repairs per the ship’s force commanding officer; assist the crew with diagnosing engineering, computer and automation deficiencies, along with reporting ship repairs and requisition of spare parts.

Preventative Maintenance

DMEC Chief Engineers, Field Engineers and Mechanics perform numerous tasks for the preventative and corrective maintenance availabilities for the LCS ships. These include but are not limited to the following:

  • Exterior & Interior Communication, Radar, Tactical Computing Environments, Roll-ing Air Frame Missile, Operations & Navigation Systems
  • Main Propulsion Diesels—MPDE’s
  • Gas Turbines—GT’s
  • Ships Service Diesel Generators—SSDG’s
  • Main Reduction Gears Combiner and Splitter Gears—MRG’s
  • Main Switchboards and Electrical Distribution Systems
  • Water Jet Hydraulic and Lube Oil Systems
  • Damage Control Equipment
  • All Operation Gears—Anchor Windlass, RHIB Crane, Mooring Winch Gear, Launch Handling and Recovery System—LHRS, WTD’s and all Hydraulic Systems
  • Fire Detection System, Fire Suppression Systems and Flooding Systems
  • Fuel Oil Service and Transfers Systems
  • MSW, VCHT, and HVAC Systems
  • Motor Operating Valves—MOV’s

Emergent Repairs/Corrective Maintenance

DMEC engineers have experience in the following emergent repairs and corrective maintenance work:

  • Sequential Turbo Charging Valves—STC (Troubleshoot, Repair and Replace)
  • Tank Level Indicator—TLI (Troubleshooting and Calibrating)
  • Diagnosing Motor Operated Valve (MOV) Deficiencies
  • Main Plant Control and Monitoring System Communications Fault Finding
  • Ship Service Air Compressors (Troubleshoot, Repair and Overhauls)
  • HVAC Repairs (Fans, Compressors, Condensers, Valves and etc.)
  • Overhauling Fuel Oil Purifiers
  • Rebuilds of Main Sea Water Valves
  • MPDE Fuel and Lube Oil Filters
  • Pump Repairs and Rebuilds
  • Replacement of the MPDE FO Injectors
  • Fire Detection Troubleshooting and Repair
  • Overhauling of the Gas Turbine Fuel Oil Service Pilot Valves
  • Troubleshooting Variable Frequency Drives (VFD’s)
  • Overhauling of the Control and Pressure Regulating Valves
  • Calibration of the MPCMS Pressure Transducers and RTD’s
  • LHRS Troubleshooting and Repairs

Builders and Acceptance Trials—Chief Engineers

DMEC Engineers operate the engineering plant during dock, builders and acceptance trials in preparation for the delivery of the LCS ships to the Navy.

  • Ensure the Proper Operation of the Hull’s Mechanical & Electrical Systems for INSURV inspection
  • Conduct Automation Test Procedures for Main Propulsion & Auxiliary Equipment
  • Operate & Test the Ship’s Fire Detection and Suppression System

Crew Familiarization Training—Instructors

DMEC engineers instruct, as well as provide their expertise to assist in the development of the Crew Familiarization Training curriculum. Classes are small and interactive. Power Point Presentations are used in the classroom training, and aboard the ship, the LCS crew learn hands-on how to operate and maintain all HM&E equipment for the various LCS Freedom class ships.

Test and Watch Engineers

DMEC provide Test Engineers to test HM&E systems in preparation for builders and acceptance trials.  DMEC Watch Engineers monitor the ship’s machinery remote control system.
