Marine Construction Insurance Requirements in New York
Before a dock, bulkhead or pier job starts in New York, three sets of rules decide what you must carry: New York law, federal maritime law, and the contract. Miss one and you can lose the job, the claim, or both. Here is the checklist we use.
Marine construction in New York triggers three layers of requirements. State law: employers must carry New York workers' comp and disability and Paid Family Leave benefits, and permit offices and owners ask for proof on official forms. Federal law: employees in maritime employment injured on navigable water or an adjoining pier, wharf or similar area are covered by the Longshore and Harbor Workers' Compensation Act, so the employer must secure USL&H coverage; failing to do so is a misdemeanor with fines up to $10,000. Crews of vessels fall under the Jones Act instead, covered by Maritime Employers Liability. Contracts: owners and GCs typically require marine or contractor's GL with completed operations, additional insured status, waivers of subrogation, P&I for any vessel, and an excess or bumbershoot layer.
This is the requirements checklist. For what each coverage does and how we build the program, see marine contractors insurance in New York.
1. New York state requirements
- Workers' compensation: required for employers in New York, including contractors with part-time workers. See New York workers' compensation insurance.
- Disability and Paid Family Leave (DBL/PFL): required statutory benefits for most private employers in New York.
- Proof for permits and owners: New York permit offices and many owners ask for proof of comp and DBL on the Workers' Compensation Board's forms, not just an ACORD certificate.
- Labor Law exposure: on land-side and shoreline work, Labor Law 240 and 241(6) can apply. See NY Labor Law insurance.
2. Federal maritime requirements
| Rule | Who it covers | What you need |
|---|---|---|
| Longshore Act (33 U.S.C. 901 et seq.) | Employees in maritime employment, including harbor workers, injured on navigable water or an adjoining pier, wharf, dry dock, terminal or similar area | USL&H endorsement on the comp policy, or a federal policy |
| Marina construction | The Act's marina exclusion does not apply to employees building, replacing or expanding a marina | USL&H for marina construction crews |
| Subcontractors (33 U.S.C. 904(a)) | If a sub fails to secure coverage, the contractor above it is liable | USL&H certificates from every sub |
| Jones Act (46 U.S.C. 30104) | Seamen: employees with a substantial connection to a vessel, such as crane barge, tug or dredge crews | Maritime Employers Liability |
| Penalty (33 U.S.C. 938) | Employers that fail to secure Longshore coverage | Misdemeanor: fine up to $10,000, up to 1 year in prison; officers personally liable |
The full breakdown is on our USL&H insurance New York page. Crew coverage for vessels is also covered in our guide to crew insurance and the Jones Act.
3. Contract requirements: the certificate checklist
Public owners, port and municipal agencies, developers and GCs on New York waterfront jobs commonly require:
| Requirement | What to check |
|---|---|
| Comp with USL&H | The certificate must show the USL&H endorsement, not just state comp |
| Maritime Employers Liability | Required when crews work aboard vessels on the job |
| Marine or contractor's GL | Limits per occurrence and aggregate, completed operations, no watercraft gap |
| Additional insured | Ongoing and completed operations, primary and non-contributory, often on P&I and excess too |
| Waiver of subrogation | On GL, comp and hull |
| Hull & P&I | For any barge or work boat on the job, with the owner named where required |
| Pollution | Often required for dredging, fueling or work near sensitive waters |
| Builders risk | Who buys it, and whether it covers work in and over water |
| Excess / bumbershoot | Over GL, P&I, MEL and employer's liability, at the contract limit |
Read the insurance section before you bid. Requirements on public waterfront jobs are often stricter than your current program. Sending it to us before you price the job lets you include the real insurance cost and avoid signing something your policies cannot meet.
4. Indemnity and Labor Law on waterfront jobs
New York contracts usually ask the sub to indemnify the owner and GC. On land-side work, Labor Law claims often come back to the sub through that indemnity. On the water, federal maritime law may apply instead, depending on where and how the accident happens. Your GL needs to cover the contract indemnity and must not carry an action-over or employee-injury exclusion that removes it. See indemnity and hold harmless in NY construction and marine general liability insurance.
Quick checklist before mobilizing
- Comp and DBL/PFL proof on New York forms
- USL&H endorsement shown on the comp certificate
- MEL for any crew assigned to a vessel
- GL or MGL with completed operations and the required AI, primary and waiver wording
- Hull and P&I for every vessel on site
- Builders risk confirmed (who buys it, what it covers)
- Excess or bumbershoot at the contract limit
- USL&H certificates collected from every sub
Pricing for all of this is in how much marine contractor insurance costs in New York.
Fastest way to a quote: email your current policies (workers' comp with any USL&H endorsement, GL, hull and P&I), 5 years of loss runs, payroll split between land work and work on or over the water, your vessel and equipment schedules and the insurance section of a typical contract to adolfo@nextguardinsurance.com. One complete submission moves faster than ten phone calls.
Please send your account to one broker. The marine market is small; when several brokers submit the same account to the same underwriters, the account gets blocked and quotes slow down.

Frequently Asked Questions
What insurance is required for marine construction in New York?
Most marine contractors need New York workers' comp and DBL/PFL, a USL&H endorsement for employees covered by the federal Longshore Act, Maritime Employers Liability for crews who may be Jones Act seamen, and the liability, P&I, builders risk and excess coverage their contracts require.
Is USL&H required for dock and pier construction?
Usually yes. Building and repairing docks and piers is harbor work, and injuries on navigable water or an adjoining pier or wharf meet the Longshore Act's situs test. Employers whose workers meet both tests must secure Longshore coverage.
What happens if a marine contractor does not carry USL&H?
Failing to secure Longshore compensation is a federal misdemeanor under 33 U.S.C. 938, punishable by a fine up to $10,000, up to one year in prison, or both, and corporate officers can be held personally liable. The employer also stays responsible for the injured worker's benefits.
Am I responsible if my subcontractor has no USL&H coverage?
Yes. Under 33 U.S.C. 904(a), if a subcontractor fails to secure Longshore coverage, the contractor becomes liable for compensation to the sub's employees. Collect a certificate showing the USL&H endorsement from every sub before they start.
What certificates do owners require from marine contractors?
Typically a comp certificate showing USL&H, Maritime Employers Liability, GL or marine GL with completed operations, additional insured status on a primary and non-contributory basis, waivers of subrogation, P&I for vessels on the job, and an excess or bumbershoot policy.
Does New York Labor Law apply to waterfront construction?
It can. Labor Law 240 and 241(6) apply to many construction projects in New York, including some shoreline work, but federal maritime law may apply on the water depending on where and how the accident happens. Contractors need coverage that responds either way.
