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 gas turbine 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 supervision during demanding 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

Plant-control duties supervising engineering watchstanders during departures, anchoring, and underway replenishment transfer directly to civilian ship propulsion operations.

How to prepare: Gather an official sea-service transcript or assignment history, with vessel characteristics, routes, propulsion power, underway time, and duties, for Coast Guard evaluation against the appropriate engine-officer endorsement checklist; a DD-214 alone is not acceptable sea-service evidence. Entry requires the applicable MMC and endorsements, generally a TWIC, and satisfaction of Coast Guard experience, citizenship, medical, drug-testing, training, and professional-competence requirements, with STCW requirements 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.

Notes & Sources

  • U15E plant-control authority applies when designated by the commanding officer and in the absence of the Engineer Officer, ACE, or MPA.
  • The Coast Guard determines the grade, class, and limits supported by military sea service. Eligibility for Chief Engineer unlimited through military service requires service in the capacity of engineer officer, not merely possession of the U15E designation.
