Harbor construction and work on navigable water can create Longshore obligations. Vessel crew members are excluded from Longshore coverage and may instead have Jones Act rights. Duties, work location, and connection to a vessel matter, so have the actual crew arrangements reviewed rather than treating a maritime endorsement as a universal answer.

Builders risk may help protect work in progress against storm and wave loss before completion, but it depends on policy terms, the project structure, and any flood or named-storm provisions.

A pollution policy may address a covered release, but fuel cleanup, disturbed contaminated sediment, and routine turbidity control are different obligations. Provide the permit and method of work, and review vessel pollution and contractor pollution terms together.

Check the actual port, government or private contract and any applicable public-work rule for performance or payment requirements. The bonds support different specified obligations to the obligee or eligible beneficiaries, subject to approval and capacity review. They are not accident insurance, and indemnity may require reimbursement to the surety.

Equipment terms may address covered physical loss to insured cranes and rigging at accepted locations. Check scheduled values and afloat use, loading, unloading, and lifting from a barge. Barges and tugs need their own hull and vessel-liability review. A crane schedule alone does not establish vessel coverage or payment of every salvage and recovery expense.

List owned and chartered vessels, floating plant, operating waters, crane values, payroll by crew duties, and environmental methods. Include contracts allocating vessel, worker, and pollution responsibilities and a record of prior losses.
