U15F Senior Shipboard Enlisted Engineering Maintenance Manager (Top Snipe)

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

The Senior Shipboard Enlisted Engineering Maintenance Manager assists the Engineer Officer with the welfare, health, job satisfaction, morale, training, good order, and discipline of enlisted engineering personnel. In the designated absence of engineering leadership, this manager serves as Plant Control Officer and personally supervises plant operation during departures, anchoring, underway replenishments, and other periods requiring extra care.

Core Skills

  • Plant supervision during demanding ship evolutions
  • Engineering personnel 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

When designated by the commanding officer in the specified officers' absence, this specialist supervises engineering watch personnel during departures, anchoring, and underway replenishment, directly overlapping shipboard plant operations.

How to prepare: Assemble an official sea-service transcript or assignment history with vessel tonnage, routes, propulsion power, underway time, and assigned duties for an NMC engine-endorsement evaluation; a DD-214 is not acceptable sea-service evidence. Use the applicable NMC checklist to plan for the MMC and engine endorsement, TWIC requirements, and Coast Guard review of experience, citizenship, medical fitness, approved training, professional competence, and drug testing.

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

  • The Coast Guard determines the grade, class, and limits of the endorsement supported by military sea service. Military-service eligibility for Chief Engineer unlimited requires service in the capacity of engineer officer; the Top Snipe designation alone does not establish that capacity.
  • Open-ocean service requires USCG-verified STCW training; an STCW endorsement generally also requires the appropriate national endorsement.
