Hull Maintenance Technician

E-4 (Specialist/Corporal) · Navy

E1–E3E-4E-5E-6E-7E8–E9
HEADS UP

As HT3 you own a watchstation, a section of the 3-M schedule, and at least one HTFN whose PQS you are signing. The weld progression is real now — the 1G was the entry ticket, the full position battery (1G through 4G, SMAW; 1G/2G GTAW) is the working credential. Start the AWS CWI weld-experience log now, even if the exam is years out. Those hours compound and the HT who waited until HT1 to start the log lost years he cannot get back.

The Honest MOS Read
HT3 is the first paygrade in the HT rate where the division treats you as a producing member instead of an apprentice in training. The crow means the work center assigns you jobs, not assists; you sign HTFNs' PQS, not the other way around; and the LPO expects your section of the MRC schedule to run without him monitoring every card. That transition from 'learning by watching' to 'accountable for output' is the defining adjustment at this rank, and the HT3s who miss it — who still perform as if someone else is accountable for the completion of what they started — are the ones the LPO has to re-counsel at the six-month mark. The technical work at HT3 centers on the full weld-position progression. You have the 1G from A-school and the first duty station. Now you pursue 2G (vertical groove), 3G (vertical plate), and 4G (overhead) in SMAW, and 1G/2G in GTAW, in whatever sequence the Welding Inspector and the ship's qualification schedule allow. Each position tests a different technique variable — 2G requires controlling the molten pool against gravity on one axis; 4G requires controlling it against gravity on both axes while working overhead with spatter falling toward your face. The Inspector accepts or rejects on visual inspection and bend test. The HT3 who approaches each new position as a skill to build rather than a test to pass advances through the battery faster. Pipe-flange replacements and hull-penetration repairs become real job assignments at this paygrade. The sequence — P&ID trace, system isolation and tagout, cut and fit, weld per WPS, NDE (visual and dye-penetrant), pressure test, system restoration, 3-M log — is one continuous procedure, and the LPO expects the HT3 to own the entire sequence, not just the welding step in the middle. The tagout package is yours. The pressure test is yours. The log entry is yours. When the HT3 calls the job 'complete' and the Welding Inspector finds a dye-penetrant indication on the heat-affected zone, the conversation starts with 'walk me through the NDE procedure you performed.' The Hotwork Permit evolution becomes fully your responsibility at HT3. As an HTFN, you assisted and observed; as an HT3, you initiate the permit, document the hazardous-atmosphere test, post and brief the fire watch, and maintain the watch through completion and post-work inspection. One permit shortcut — an undocumented atmosphere test, a fire watch who left the evolution early, a post-work inspection that did not happen — and the JAGMAN investigation opens with the HT3's name as the permit initiator. The NEC pipeline conversation moves from planning to action at this paygrade. The LPO who was neutral about your NEC preference as an HTFN becomes an advocate or an obstacle depending on whether you have demonstrated the technical competence and professional maturity the C-school application requires. Pull the current NEC source-rating NAVADMIN from MyNavyHR before the counseling session — the message tells you what NECs have open billets and what the application requirements are. The HT3 who walks into that conversation with the NAVADMIN message number and the application packet started is the HT3 the LCPO champions.
Career Arc
  • 01HT3 pin-on post-NWAE advancement cycle.
  • 02Full weld-position qualification battery (1G-4G SMAW; 1G-2G GTAW minimum) — documented in the ship's welder-qualification record.
  • 03First pipe-flange replacement or hull-penetration repair executed as the responsible petty officer.
  • 04First Hotwork Permit evolution initiated and owned as HT3.
  • 05NEC pipeline packet in motion — application submitted or C-school date locked.
  • 06NWAE BIB for HT2 pulled and study log running.
  • 07Surface Warfare device pinned where the billet allows.
  • 08Advancement to HT2 via NWAE cycle — exam + service record review.
Common Screwups
  • ×Exceeding the scope of a WPS to 'make it fit' instead of stopping and calling the LPO. Welding outside the approved procedure invalidates the weld, requires cut-out and re-weld, and puts your name on the Welding Inspector's discrepancy log for the production record.
  • ×Performing a system repair without completing the tagout package. One re-energized line or premature valve opening in a pressurized system is a JAGMAN investigation with the petty officer's name in the first paragraph.
  • ×Going around the LPO to the DCA with a work-authorization disagreement. The DCA hears it either way; which path you took is part of every eEVAL conversation afterward, and the LPO does not forget.
  • ×Treating the DC drill as separate from the welding job. The DCA runs the repair division; the HT3 who cannot perform both functions under pressure is a liability in both spaces.
  • ×NEC application delay — waiting for someone to tell you when to submit instead of watching the NAVADMIN cycle yourself. School slots go to the HT3s who submitted early.

A Day in the Life

  • 0500Wake up. If you are in the duty section today, you are already awake — you stood the 0200-0600 DC roving watch and you are logging the turnover report right now.
  • 0530PT formation. Take accountability for yourself and any HTFNs in your section who are in the duty section with you. Report to the LPO.
  • 0545-0700Unit PT. You set the pace your section is watching — the HT3 who falls out of the run has to have the 'here is why that does not happen again' conversation with the LPO the same morning.
  • 0700-0900Hygiene, breakfast, OCP change. Morning quarters at 0745: the LPO distributes today's work assignments. You receive a pipe-flange replacement work order on Frame 32 Port and an MRC card for the firemain drain valve PM.
  • 0900-1130Work call. Walk the Frame 32 P&ID in the engineering drawings library first — before you touch a valve. Open the tagout package, notify the watch supervisor, verify system isolation. The HTFN assigned to you is watching how you run the sequence.
  • 1130-1300Break for chow. Log the tagout status in the work-order record before leaving the space. Never leave an open tagout without logging the status — if the ship has a casualty while you are in the galley, the duty watch team needs to know the valve lineup.
  • 1300-1500Afternoon: cut the flange, fit the new section, run the weld. The HTFN hands you tools. You explain each step as you go — teaching is the PQS pipeline and the LPO is going to ask the HTFN what he learned.
  • 1500-1700NDE on the completed weld — visual first, then dye-penetrant if the visual passes. Pressure test. System restoration. Log the completion in CSMP. Close the tagout. This sequence does not compress.
  • 1700-1900Clean the shop. Return tools. Evening quarters if the division runs them. BIB study block — 30 minutes on whichever chapter is up in the rotation.
  • 1900-2100Personal time. If you have an HTFN PQS demonstration to run, now is the window — run it, sign or defer, log the outcome.
  • Underway rotationAdd repair-locker petty officer of the locker watch to the rotation — 4 hours on, 8 hours off. During GQ, you own the locker: inventory check, equipment readiness, phone-talker management, DCC reports in SORM format. The drill evaluator's grade is yours.

Weekly Cadence

At HT3 the week runs on the work-order queue and the PMS schedule simultaneously. Monday morning the LPO distributes the week's MRC cards and any new CSMP work orders. You read both, estimate the time requirements, and identify the HTFN who will assist on each job — this planning happens before 0900, not as you walk into the space. The production days (Tuesday through Thursday) are where the pipe and structural work happens. A pipe-flange replacement runs half a day minimum including tagout and system restoration; a structural weld repair on hull plating can run two days if NDE and material-processing time are included. You do not rush the NDE or skip the pressure test because the work day is ending. Log the partial completion status and pick it up the next morning. Friday has a clean-sweep-down evolution, equipment inspections, and the LCPO's weekly compliance check. The LPO walks the work center and asks each petty officer for a 3-M status update — MRC completions, open work orders, any discrepancies found. The HT3 who can brief his section's status without looking at his notes has been doing daily tracking; the one who has to pull up OMMS-NG and squint has not. The LCPO notices the difference.

Key Skills — How to Drill Each

  1. 01
    Qualify in at least two weld positions beyond 1G — NSTM 074 / AWS D1.1 standard — and pass the Welding Inspector's visual and bend test on the first attempt.
    Do not book a test date until you have run ten consecutive practice coupons in that position that you would stake your qualification record on. The technique differences between 1G and 2G are real: the molten pool wants to run downhill in the 2G position and the travel angle has to compensate. Ask the HT2 who just passed his 3G to run practice alongside you and call out technique errors. The first attempt pass matters — a second-attempt pass is fine mechanically but tells the LPO you are booking tests before you are ready.
  2. 02
    Perform a pipe-flange replacement or hull-penetration repair from tagout through system restoration: P&ID trace, isolation, cut and fit, weld, NDE, test, log.
    Walk the P&ID with the LPO before you touch a valve. Tag out per the ship's LOTO (Lockout/Tagout) SOP — the tag goes on the physical valve with your name on it and a log entry in the tagout record. Execute the repair to the applicable WPS. Perform visual inspection first, then dye-penetrant (PT) on the weld and heat-affected zone per ASTM E165 / NAVSEA procedure. Pressure-test to the applicable system test pressure per NSTM Chapter 505. Log every step. Close the tagout only after the test is complete and recorded.
  3. 03
    Stand a DC repair-locker watch as petty officer of the locker — accountability, equipment readiness, phone-talker control — and run the drill assignment without the chief walking you through it.
    Before the GQ drill, walk the locker: every piece of equipment to SOP, plugs and wedges by size and type, hose-kit inventory complete, EAB/OBA serviceable. During the drill, the phone-talker reports to you; you report to Damage Control Central (DCC) in the SORM format. Do not freelance — execute the assignment you were briefed. The drill evaluator is watching whether the locker is manned and ready within the required time window and whether your reports to DCC are clear, accurate, and formatted correctly.
  4. 04
    Conduct a topside hull inspection and log findings against NAVSEA S9086-CH-STM-010 criteria: coating condition, wastage, deformations, weep holes.
    Walk the topside in a systematic grid pattern — port side bow-to-stern, then starboard stern-to-bow — with a clipboard, a rust-probe, and a flashlight. The S9086 criteria for acceptable coating condition and allowable wastage are in the structural inspection chapter. Log compartment number, frame station, and nature of discrepancy for every finding. If you find a wastage measurement outside the allowable limit, log it as a CSMP work order before you close the inspection record. Do not verbal-report findings to the chief without the paperwork to back it up.
  5. 05
    Execute a full Hotwork Permit evolution as the initiator: atmosphere test, fire watch posted, permit completed and signed, watch maintained, post-work inspection logged.
    The permit initiator's responsibility runs from before the first arc to after the last spark dies. Before: hazardous-atmosphere test in the space (oxygen-deficient, flammable gas, toxic) with a calibrated meter and the meter's calibration date on the permit. During: fire watch posted at the weld location, not at the door. After: post-work inspection of the space and adjacent compartments 30 minutes after work stops, signed on the permit by the fire watch and by you. The fire watch who wanders off during the evolution is your administrative problem, not a coincidence.
  6. 06
    Mentor an HTFN through five to eight PQS line items as the signature authority — your name is on the standard.
    Sign a PQS line item only after the HTFN has demonstrated the task to your satisfaction in front of you. 'He says he can do it' is not a signature-level evaluation. Walk the HTFN to the equipment, have him explain the procedure, and watch him execute it. If the execution is wrong, correct it and schedule a re-demonstration. The PQS chain exists because an unqualified sailor performing a task unsupervised creates a casualty risk — your signature is the chain's quality gate.

Manuals & References — What Chapters Matter

  • NSTM Chapter 074 — Welding and Allied Processes
    You teach it now. Know the qualification tables well enough to explain to an HTFN why the 3G position requires a different amperage range than the 1G, why the WPS governs the filler metal selection, and what the bend-test acceptance criteria mean in physical terms. The HT3 who has to look up the basic qualification table in front of the HTFN loses credibility he will not get back that day.
  • NAVSEA S9086-CH-STM-010 — Hull Structures
    You are executing structural repairs and topside hull inspections against this manual's criteria. Know the structural inspection chapter — what constitutes reportable wastage, what the acceptable coating-condition categories are, and what the correction-by-inspection vs correction-by-repair threshold is. The LPO's structural inspection brief to the DCA references this manual by chapter and section.
  • AWS D1.1 — Structural Welding Code – Steel
    Know what CJP (complete joint penetration) and PJP (partial joint penetration) mean before your next conversation with the Welding Inspector. Know what 'prequalified joint' means. Know what it means to 'exceed WPS scope.' The Inspector quotes D1.1 section numbers; the HT3 who can respond in kind is the petty officer the Inspector treats as a peer.
  • OPNAVINST 4790.4 series — 3-M Systems Procedures Manual
    Own the MRC library for your assigned work centers. Know the difference between a scheduled PMS evolution and a corrective-maintenance work order — they go into different parts of the 3-M record. Know how to open a CSMP work order for a discrepancy you found during a hull inspection. The LPO expects the HT3 to manage the section's 3-M posture without daily hand-holding.
  • NAVPERS 18068 Vol II — NEC catalog; current NEC source-rating NAVADMIN from MyNavyHR
    Read the NEC entries for your intended track — the C-school prerequisites, the sea-time requirements, and the application process. Then pull the current cycle NAVADMIN for HT-rate NEC source-ratings to find out which NECs have open billets. The HT3 who walks into the career-counselor conversation with both documents is the one who gets the LCPO advocacy at the next selection board.
  • NWAE Bibliography for Advancement (BIB) for HT2 cycle — current from MyNavyHR / NETC
    The BIB is the test. Pull it at HT3 pin-on, build a study plan, and run the plan. The HT2 advancement exam covers PMS, weld procedures, DC systems, piping fundamentals, and naval regulations. The HT3 who studies from the BIB rather than from whatever materials look interesting is the one who scores in the top third of the exam cycle.

Standards — How to Hit Each

  • NWAE for HT2 prep on the LCPO's timeline — the HT3 who walks into the exam cold is the one watching the advancement slate from the bench.
    Four days a week, 30 minutes per session, chapter-by-chapter through the BIB. Keep a study log with dates and chapters covered and show it to the LPO when he asks. Identify the BIB chapters that cover your technical weak spots — the HT3 who is strong on welding procedure but weak on DC systems PMS needs to spend more time on the DC chapters. The advancement exam does not reward specialization; it rewards breadth.
  • Full position-weld qualification battery (1G through 4G, SMAW; 1G-2G GTAW at minimum) documented in the ship's welder-qualification record before the next INSURV.
    Schedule one position test per month as a baseline cadence after the HT3 pin-on. Do not let more than 60 days pass between test attempts when a position is still open in your record. The INSURV inspection team spot-checks welder qualification records against the list of HTs performing structural work — an HT3 executing production repairs with a partial qualification record is a finding that goes on the division.
  • PRT Good Medium or better; BCA in standard. Tender and ship repair work is physically demanding.
    The HT3 who falls out of a 4-hour overhead welding evolution because his shoulder and back gave out is a production problem. Train for the physical demands of the job, not just the PRT. Overhead welding requires shoulder and upper-back endurance; working in confined bilge spaces requires hip flexibility and core stability. Add targeted strength work — pull-ups, rows, overhead press, kettlebell carries — alongside the PRT prep runs.
  • Zero Hotwork Permit violations attributed to your evolutions — a permit bypass is summary court-martial territory.
    Before every hotwork evolution, run through the permit checklist mentally from memory: atmosphere test (meter calibrated, result logged), fire watch posted and briefed (stationed at the weld location, not the door), permit signed by division officer or OOD. Then run through it on the paper permit. The two-check method catches the item you would otherwise miss because you are focused on getting the weld started.
  • NEC pipeline packet in motion or documented reason it is still building — the HT3 without a specialty track is passed over when C-school slots hit the board.
    The LCPO builds the C-school nomination list from the division's current qualification records and advancement-board inputs. The HT3 who comes to that conversation with a complete application packet or a clear timeline for completing the prerequisites gets the slot when it opens. The HT3 who says 'I'm working on it' without paperwork to show is the HT3 who watches the slot go to a peer.

Technical Mistakes — Concrete Consequences

  • Exceeding the scope of a WPS (Weld Procedure Specification) to make a repair fit.
    NAVSEA S9086 and NSTM 074 require welds to be performed within the approved WPS parameters. A weld outside WPS scope is not a qualified weld — it has to be cut out, the area prepped, and the repair re-performed to the correct WPS. The Welding Inspector's discrepancy log cites the responsible petty officer, and the INSURV team reads discrepancy logs. This is not a warning; it is a production failure that erases the work order's progress.
  • Performing a system repair without completing the tagout package.
    If a system is re-energized while your hands are in it, the injury investigation opens with the petty officer's name on the incomplete tagout as the responsible party. Even if the injury does not happen, a TYCOM safety inspection that finds a system under maintenance without a completed tagout produces a formal safety finding, an administrative investigation, and a note on the division's safety record that traces to the work order.
  • Calling a weld 'visual-pass' when you can see the defect but hope it will hold.
    NAVSEA S9086 visual-inspection acceptance criteria are binary: within limits or not. The Welding Inspector who re-inspects and finds an undercut below the allowable threshold in a weld you signed off as 'visual-pass' pulls the production record, finds your sign-off, and the subsequent discussion is not a teachable moment — it is an integrity finding. Cut it out and re-do it.
  • Treating the DC drill as a separate job from the welding job.
    The DCA's readiness assessment grades both. The HT3 who is technically excellent in the shop but performs poorly at general quarters stands out to the LCPO in the wrong direction — the rate's strength is that its members understand that structural integrity and damage control are the same mission viewed from different angles. A mediocre drill performance under the DCA's observation is a data point that affects the eEVAL ranking.
  • Going around the LPO to the DCA or the XO with a work-authorization disagreement.
    The DCA hears about it within the day. The LPO hears about it within the hour. Whether or not you were technically correct about the work authorization, you have demonstrated that you bypass the chain of command when you disagree with it, which is a leadership quality the Navy does not reward at any paygrade. The path is: make the case to the LPO; if the LPO is wrong, the chain above him fixes it.

Career Decisions at This Rank

  • NEC C-school application timing
    The HT3 window is the first realistic application window for most NEC C-schools. The advanced welding NEC requires documented weld experience hours — start the AWS weld log now regardless of which NEC you ultimately pursue, because AWS CWI experience hours are the civilian-portable credential that matters after your Navy career. The pipe/valve NEC track opens fleet billets on large ships and tenders. The diver track requires a physical screening test and often a selection before or during A-school — if you want that path and you missed the A-school window, the enlisted-in-service underwater-breathing-apparatus (UBA) pipeline is the route, but seats are limited. Make the decision and start the application before the LCPO has to ask.
  • Surface Warfare designation
    SWE qualification at HT3 is achievable within 12-18 months on a surface combatant. The qualification requires a series of watchstander qualifications, a comprehensive PQS completion, and an oral board in front of the department head. The SWE device is visible on the uniform and on the service record — advancement boards and eEVAL ranking boards use it as a data point. Start the process in the first year; the HT3 who is still unqualified at 24 months on a ship is the one whose eEVAL says 'in progress' while peers say 'qualified.'
  • Re-enlistment timing and bonus math
    The HT3 re-enlistment window typically opens in the 17-24 month range before EAOS. Pull the current SRB NAVADMIN from MyNavyHR before talking to the career counselor — the bonus structure for the HT rate changes by cycle and by NEC. The trap: re-enlisting for the bonus money before you have enough experience in the rate to know if this is the career you want for the next six years. A shorter contract with a lower bonus preserves flexibility. Run the math on the full compensation package, not just the bonus check.

How the Seat Varies by Unit Type

  • Surface combatant R-Division (DDG, CG, LHD)
    The production-and-readiness split. Half your week is NSTM 074 welding standards and structural repairs; the other half is NAVSEA OD 45845 DC readiness and repair-locker watchstanding. The DCA knows your name by month three and whether it's a good or bad association depends entirely on your 3-M posture and your drill performance.
  • Tender or afloat repair ship (AS, AR)
    Production shop environment with multiple ships as customers. You run higher welding volume, encounter a wider range of WPS families, and interact with NAVSEA technical authority more frequently than on a combatant. The administrative rigor of the production record — sign-offs, NDE documentation, work-order closeout — is more formalized because the customer ships rely on the documentation for their own INSURV records.
  • IMA (Intermediate Maintenance Activity)
    Shore-side depot tempo. Eight-hour days, more specialized equipment, formalized quality-assurance program. An IMA tour deepens technical skill and teaches you how the NAVSEA maintenance system works above the ship level. It does not build the shipboard watchstanding and DC experience that the advancement record rewards at HT3.
  • Large-deck (LHD, CVN)
    Large R-Division with more complex systems and a more formal administrative environment. The Hull Division LCPO on a CVN is a senior chief who has seen every certification and inspection standard; the bar for production quality is correspondingly higher. Greater access to formal training and more senior HTs to learn from — but the administrative machinery is heavier.

What Good Looks Like at This Rank

The good HT3 is the petty officer the LPO sends to a complex topside repair job while the chief is at a meeting and the job comes back with the P&ID trace documented in the work order, the Hotwork Permit filled out and signed before the first arc struck, the post-weld visual clean, the dye-penetrant indication log showing two passes with no recordable indications, and the system test recorded and logged before the petty officer walked out of the space. The LPO did not have to follow up. The DCA did not have to ask. The work order is closed in CSMP with the correct completion codes and the right authorizing petty officer's name on the right signature lines. His HTFN has five PQS line items signed off this month — not because the HT3 was generous, but because he scheduled the demonstrations into the week's work plan and held the HTFN to the task standard before signing. The HTFN knows the HT3 will not sign off on work he has not seen performed correctly, which means the PQS entries in that HTFN's record mean something. The HT2 advancement BIB is on the HT3's tablet. The study log has 18 entries over the last six weeks. He does not talk about it because the LPO already knows — the LPO gave him 30 minutes of liberty-section time per day for the three weeks before the exam window, and the HT3 used every minute of it. Whether he advances this cycle depends on the exam score and the quota, not on preparation. He has done what preparation can do.

Preview — The Next Rank

HT2 is when you become the LPO's partner rather than his production resource. The HT2 runs a section independently, writes the section's 3-M compliance brief, manages the HTFN and HT3 PQS pipeline, and mentors the NEC / CWI / commissioning conversation that the LPO does not have time to run for every junior sailor. The technical work does not go away — the HT2 still holds a wrench and still signs welds — but the weight of the week shifts toward the people in your section and the paperwork that validates their progress. The AWS CWI exam path becomes real at HT2. The exam requires documented weld-experience hours in specific process categories — start that log at HT3 and let it compound. The HT who waits until HT2 or HT1 to start the log has lost 18-24 months of documentable hours that the exam requires.
