Ship Building and Repairing
NAICS 336611 · United States · 2022 edition
This U.S. industry comprises establishments primarily engaged in operating shipyards. Shipyards are fixed facilities with drydocks and fabrication equipment capable of building a ship, defined as watercraft typically suitable or intended for other than personal or recreational use. Activities of shipyards include the construction of ships, their repair, conversion and alteration, the production of prefabricated ship and barge sections, and specialized services, such as ship scaling.
Start the review with marine general liability.
For Ship Building and Repairing, the saved research highlights marine general liability, workers' compensation / longshore and harbor workers, builders risk / hull under construction. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What types of vessels are built or repaired — commercial, government, offshore platforms, recreational?
- What is the average and maximum single-vessel value under construction at any one time?
- How many direct employees versus subcontractors are on-site, and what is the total payroll split?
- Does the operation have any prior LHWCA claims or litigation history?
- Are there any fuel storage, painting, or chemical handling operations and what environmental controls are in place?
- Has the yard had any prior environmental incidents, spills, or regulatory actions?
- For Ship Building and Repairing, what should the underwriter know about prior marine liability, pollution, or lhwca losses with high severity?
- For Ship Building and Repairing, what should the underwriter know about construction of naval, submarine, or highly specialized government vessels without confirmed program experience?

Shipyards are fixed industrial facilities equipped with drydocks, fabrication shops, and heavy lifting equipment used to build, repair, convert, or alter large watercraft — including commercial cargo vessels, barges, passenger ships, offshore drilling platforms, and specialized government vessels. Day-to-day work involves structural steel fabrication, welding, outfitting, electrical and mechanical systems installation, and vessel launches, with large workforces often including direct employees and subcontractors working simultaneously on complex, long-duration projects. This class typically sits well outside standard small-commercial appetite and is noted here primarily for educational reference.
