U15C Senior Shipboard Enlisted Engineering Maintenance Manager (Top Snipe) Candidate (Steam)

Current service use not established

This code is listed in the directory. Inclusion alone does not confirm current service use.

A Navy Enlisted Classification: a skill designation sailors hold in addition to their rating.

Overview

A steam Senior Shipboard Enlisted Engineering Maintenance Manager candidate serves as Plant Control Officer when designated by the commanding officer in the absence of the Engineer Officer, ACE, or MPA. The candidate supervises the EOOW, PPWO, or RCO during specified plant operations and assists with the welfare, health, job satisfaction, morale, and training of engineering enlisted personnel.

Core Skills

  • Plant watch supervision during ship maneuvers
  • Engineering crew welfare and training support

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.

Ship Engineers

Supervising engineering watches as designated Plant Control Officer during departures, anchoring, and underway replenishment transfers directly to shipboard propulsion-operation oversight.

How to prepare: Assemble an official sea-service transcript or assignment history, with vessel tonnage, propulsion power, routes, time underway, and assigned duties, for National Maritime Center evaluation against an engine endorsement checklist; a DD-214 alone is not acceptable sea-service evidence. Officer entry requires the appropriate Merchant Mariner Credential endorsement and Coast Guard verification of experience, age, citizenship, physical health, character, approved training, professional competence, and drug testing, with TWIC generally required and verified STCW training required for open-ocean service.

What the civilian work involves
  • Monitor engine, machinery, or equipment indicators when vessels are underway, and report abnormalities to appropriate shipboard staff.
  • Monitor and test operations of engines or other equipment so that malfunctions and their causes can be identified.
  • Start engines to propel ships, and regulate engines and power transmissions to control speeds of ships, according to directions from captains or bridge computers.

Stationary Engineers and Boiler Operators

Supervision of a shipboard steam plant during operations requiring extra care provides directly relevant experience for overseeing stationary steam equipment.

How to prepare: Check the licensing authority for your target city or state and compare your documented steam-plant experience with the license class covering the equipment you want to operate. Some jurisdictions require experience and a written examination, with license classes limiting equipment type and size and possible reexamination after relocation.

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.
  • Analyze problems and take appropriate action to ensure continuous and reliable operation of equipment and systems.
  • 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

Notes & Sources

  • U15C Plant Control Officer duties apply only when designated by the commanding officer and in the absence of the specified engineering officers.
  • For Ship Engineers, Coast Guard evaluation determines the grade, class, and limits of endorsements supported by military service. Military-service eligibility for Chief Engineer unlimited requires service in the capacity of engineer officer, not merely the U15C designation.
