What is Longshore Workers Insurance?
Longshore Workers Insurance (often called USL&H coverage) is a specialized workers' compensation and liability program for employees who work on or around docks, piers, ships and other marine terminals. This coverage responds to job-site hazards that differ from standard commercial settings, including transportation risks, heavy equipment exposure and cargo handling. For a focused overview of policies for waterfront exposures, see Harbor Workers Insurance (USL&H).
Who needs it
Employers with marina, terminal or shipyard operations commonly purchase this coverage. Typical buyers include longshore contractors, stevedores, service and repair contractors, and companies that transport or load cargo. Smaller contractors and large operators alike can have different program needs; specialized offerings are available for both single-location firms and larger accounts. If your business performs repair or maintenance work on vessels, you may want to review options such as US Longshore and Harbor Workers Service and Repair Contractors Insurance to match exposures.
What it typically covers
Policies generally address employer liability for workplace injuries and may include related commercial liability layers. Common components include:
- Medical and wage benefits for injured workers under USL&H provisions
- Employer liability for third-party bodily injury and property damage
- Certain maritime-specific coverages such as liability during loading/unloading and vessel service operations
- Optional endorsements for equipment coverage and commercial auto exposure tied to cargo movement
Risk management measures—like equipment inspections and worker training—are often part of underwriting considerations.
Common exclusions or limitations
Exclusions may include intentional acts, certain pollution incidents, and liabilities tied to non-covered operations. Some policies limit coverage for subcontractor exposures or for activities occurring away from the insured’s primary terminal. Policies also often have unique reporting and notice requirements tied to maritime law.
Factors that influence cost
Premiums depend on payroll, the types of marine operations, historical loss experience, the amount of manual handling and heavy equipment use, and how work is transported. High-risk activities—like crane operations or night-time cargo handling—typically raise rates. In complex programs, insurers may use excess or specific excess layers to manage catastrophic exposure; for larger or high-limit needs, consider solutions such as Specific Excess US Longshore and Harbor Workers' Compensation Insurance.
Proof of insurance & compliance
Companies often need certificates of insurance to demonstrate compliance to port authorities, vessel owners and prime contractors. Documentation requirements vary by contract and location, so maintain current certificates and be prepared to show program limits, policy forms and any required endorsements.

Frequently Asked Questions
Do standard workers’ comp policies cover dockworkers?
No. Dock and vessel operations often require USL&H or Longshore-specific coverage because exposures and governing laws differ from general workplace policies.
Can subcontractors be added to my policy?
Some programs allow endorsements or certificates that extend coverage to contractors, but this depends on underwriting and contract wording. Confirm with your insurer before assigning work.
How quickly can coverage be placed?
Placement times vary by program complexity and the size of the account. Small operations may receive quotes quickly, while large accounts with excess layers may take longer to underwrite.
