Key Takeaways

  • Naval yard work sits at the intersection of three unrelated federal regimes: maritime workers compensation, maritime liability, and defense cybersecurity. None of them knows the others exist.
  • A single tradesperson can move between them inside one week without changing employers, job titles, or pay rate.
  • Each regime is separately hard to satisfy. USL&H and MEL are underwritten on decades of maritime loss history. CMMC is a documented security programme with contractual affirmations behind it.
  • Most vendors can satisfy one of the three, sometimes two. The combination is rare, which is why it functions as a barrier to entry on naval programmes rather than a checklist.
  • The practical resolution for contractors and staffing firms is to place the workforce with an employer that already holds all three, rather than trying to assemble them.

Ask a project manager at a naval yard what their compliance burden looks like and you will usually get an answer about one thing: whichever regime bit them most recently. Insurance people talk about Longshore. Programme people talk about CUI. Nobody describes the whole shape of it, because no single department sees the whole shape.

The clearest way to see it is to stop thinking about departments and follow one person.

One Welder, One Week

Take a certified welder placed on a naval surface programme at a Gulf Coast yard. Same badge, same rate, same supervisor all week.

Mon
USL&H

Fabrication shop inside the yard

Working steel on the yard, adjoining navigable water, on a vessel in build. This is maritime employment on a covered situs. If he is hurt, the claim is federal, under the Longshore Act, and a state workers compensation policy will not respond to it.

Tue
CMMC

Weld procedure issued from the programme office

He is handed a work package built from vessel drawings and system specifications. On a defense programme, that documentation is routinely Controlled Unclassified Information. Everyone in the chain that stored, transmitted, or printed it is now inside the scope of a cybersecurity requirement, including whoever emailed it to the labour vendor.

Wed
USL&H

Dry dock, working the hull

Still Longshore, still federal, still nothing to do with the state system. The exposure has not changed since Monday, but the severity profile has, because he is now working at height over a dock floor.

Thu
MEL & Jones Act

Aboard for sea trials

He sails with the vessel to finish a repair underway. Time aboard a vessel in navigation is what builds seaman status, and seamen sue rather than claim. If this becomes a pattern rather than a one off, the argument that he is crew becomes available to a plaintiff's lawyer, and the capped comp exposure the employer was relying on may not be there.

Fri
All three

Timesheet, site access renewal, weld log

The timesheet is billed to a contract line. The access renewal names a facility and a programme. The weld log references the drawing package. Payroll runs Friday because trades expect weekly pay. Three regimes, one administrative afternoon.

"Nothing about his job changed all week. What changed was which body of federal law was watching, and none of them coordinate with the others."

Three Regimes That Share Nothing

What makes this genuinely difficult is not the number of requirements. It is that they have no common structure, no common authority, and no common way of being satisfied.

Each column has its own guide. USL&H and the gap in state workers comp covers the first. MEL coverage and the Jones Act covers the second. What CMMC actually requires covers the third, including what the July 2026 suspension of Phase 2 did and did not change.

Why the Combination Is Harder Than the Sum

A company can usually solve one of these. The reason the stack is a barrier rather than a checklist is that the three are acquired through completely different mechanisms, on completely different timescales, and no amount of progress on one advances the others.

Specialty maritime coverage cannot be bought into. Carriers underwrite USL&H and MEL on demonstrated operating history in maritime environments and on loss experience over years. A well capitalised firm with no maritime record is not a candidate at any premium. That is a genuine moat, and it is why the phrase used in the industry is that these coverages are earned rather than purchased.

CMMC cannot be bought into either, though for a different reason. It requires implemented controls, documented policies, scoped systems, and an affirmation that carries liability if it is inaccurate. It is measured in months of work rather than years of history, but it is not something a broker can arrange.

Then there is the operational layer that sits underneath all of it and gets forgotten: weekly payroll, because Gulf Coast trades expect it; multi state deployment, because yards pull crews from wherever the trade exists; and the insurance certificates and documentation the yard's own compliance team will ask for before anyone gets a badge.

"Most vendors clear one of the three. A good one clears two. The set is rare enough that it decides who gets to bid."

Who Actually Carries the Stack

There are three ways a contractor or staffing firm can respond to this, and only one of them is realistic for most.

Build it. Establish maritime operations, accumulate a clean loss record over years, persuade a carrier to write USL&H and MEL, stand up a compliant information environment, and complete a CMMC assessment. This is the honest path and it is a decade long.

Avoid it. Decline naval work and stay in commercial environments. A legitimate strategy, and the one most trades staffing firms take by default without ever framing it as a decision.

Place the workforce with an employer that already holds all three. The client keeps the customer relationship, directs the work, and controls who is on the job. The Employer of Record becomes the legal employer, which puts the Longshore and maritime liability exposure on its programme and the information handling inside its environment.

That third structure is what Revelation was built around. The specialty coverage position covers the maritime side, the CMMC page covers the information side, and weekly payroll across all 50 states covers the part everyone forgets until a crew misses a Friday.

Five Questions to Ask a Workforce Vendor

If you are placing trades into a naval yard, these five questions separate vendors quickly. Ask for the answers in writing.

  1. Does your workers compensation programme include a USL&H endorsement, and can you produce a certificate showing it? A yes without a certificate is not a yes.
  2. Do you carry Maritime Employers Liability, and what is the limit? If the answer is that USL&H covers it, the vendor does not understand the exposure.
  3. What is your CMMC status, and which assessment type is behind it? Level 2 self-assessed and Level 2 assessed by a third party are different answers to a prime.
  4. Where does programme documentation about our placements live? If the answer is an ordinary commercial inbox, that is the gap.
  5. What is your umbrella limit? Large industrial and government contracts frequently set a floor that disqualifies bidders before anything else is assessed.

Frequently Asked Questions

Can one worker really fall under all three regimes?

+

Not simultaneously for injury purposes, because USL&H and seaman status are mutually exclusive at any given moment. But across a week the same worker can generate Longshore exposure in the yard, seaman status arguments while aboard, and CMMC scope through the documentation attached to the job. The employer has to hold all three positions at once even though the worker occupies them in sequence.

Does the July 2026 CMMC pause remove that leg of the stack?

+

No. The suspension paused the transition to mandatory third party certification. Phase 1 self-assessment requirements, DFARS 252.204-7012, and NIST SP 800-171 remain in force, and primes remain free to require more of their suppliers than the Department requires of them. It was also done by memorandum, which can be reversed quickly.

Our crews never sail. Do we still need MEL?

+

If that is genuinely never, the exposure is limited. The difficulty is that sea trials, riding crews, and voyage repair assignments are usually decided at short notice by the yard rather than by the labour supplier, so the answer can change without the vendor being consulted. Confirm it contractually rather than assuming it operationally.

Why would an EOR be able to hold all three when we cannot?

+

Because the cost of holding them is fixed and the volume across many clients is what makes it economic. A specialty EOR spreads decades of maritime underwriting history, an insurance programme, and a compliant information environment across a large employed population. A single contractor carrying that for one contract cannot make the arithmetic work.

Do we lose control of our workers under this structure?

+

No. Under an Employer of Record arrangement the client continues to direct the work, decide who is assigned, and hold the customer relationship. What transfers is the employment infrastructure: payroll, tax, insurance, and compliance administration, along with the liability that attaches to being the legal employer.

How quickly can a compliant placement be stood up?

+

Where the employer already holds the coverage and the security programme, onboarding runs on the timescale of documentation rather than procurement, often same day to a few days. The slow parts are typically the yard's own badging and access process rather than the employment side.
