US Longshore and Harbor Workers Insurance

What is US Longshore and Harbor Workers Insurance?

US Longshore and Harbor Workers Insurance (USL&H) is a specialized form of workers' compensation coverage designed to protect maritime employees who work on or near navigable waters. This includes longshoremen, dock workers, and ship repair personnel who may not be covered under traditional state workers' compensation laws. The coverage is mandated under the Longshore and Harbor Workers' Compensation Act (LHWCA) and helps cover medical expenses, lost wages, and rehabilitation costs related to job-site injuries.

Who needs it

This coverage is essential for businesses that employ individuals involved in maritime operations but not classified as seamen. Common policyholders include shipbuilders, stevedoring companies, marine equipment contractors, and terminal operators. Even companies that only occasionally operate near docks or piers may require this insurance to meet compliance standards and avoid potential liability exposures.

What it typically covers

USL&H insurance typically provides protection for:

  • Medical treatment for work-related injuries or illnesses
  • Wage replacement for employees unable to work
  • Vocational rehabilitation services
  • Survivor benefits in the case of a fatal accident

These benefits help employees recover while shielding businesses from costly lawsuits and operational hazards associated with maritime work.

Common exclusions or limitations

Coverage does not typically extend to crew members of vessels (who are covered under the Jones Act), office workers, or administrative staff who are not directly involved in maritime activities. Other exclusions may apply for intentional injuries, intoxication-related incidents, or injuries occurring outside covered job functions. Understanding these exclusions is important for accurately assessing risk and ensuring proper coverage is in place.

Factors that influence cost

Several underwriting factors impact the cost of USL&H insurance, including:

  • Job classifications and payroll amounts
  • Claims history and safety record
  • Location of operations and types of maritime activities
  • Inclusion of other liability exposures, such as commercial auto or equipment coverage

For example, a ship repair company with heavy equipment exposure and prior injury claims may pay a higher premium than a terminal operator with a clean safety record.

Proof of insurance & compliance

Employers must provide proof of USL&H coverage to comply with federal regulations under the Department of Labor. Certificates of insurance are typically required when bidding on contracts or working with port authorities. Failure to maintain proper coverage can result in penalties and increased liability risk.

How to get a quote

To ensure your business has the right protection, speak with a licensed insurance provider who understands maritime exposures and legal requirements. Coverage can often be bundled with other policies such as general liability or property insurance for added efficiency.

Frequently Asked Questions

Does my business need USL&H coverage if we only occasionally work near water?

Yes, even occasional work near navigable waters may require USL&H coverage depending on your employees’ roles and job-site exposures.

How is USL&H insurance different from regular workers’ compensation?

USL&H covers maritime workers not protected by standard state workers’ comp, focusing on injuries occurring on or near navigable waters.

Can USL&H coverage be combined with other policies?

Yes, it can often be bundled with general liability or property insurance for comprehensive protection and administrative convenience.

Who determines if an employee qualifies under the LHWCA?

Employee eligibility is based on work duties and location. A licensed agent or legal advisor can help interpret specific classifications.
