Identify cargo that controls commercial operation

A project can receive most of its equipment on time and still be unable to operate because one critical component is damaged in transit. Identify turbines, transformers, reactors or other items whose replacement period could move the commercial operating date. The important measure is the effect on the project schedule, not simply the shipping value or size of the package.

Chubb’s project-cargo guidance describes critical items in terms of their effect on scheduled operation. That is useful background, not a statement that its product is available for a particular project. Build a schedule showing manufacture, shipment, inland movement, installation, testing and available float for each critical item.

Separate the cargo interest from the revenue interest

Cargo insurance concerns physical loss or damage to the insured goods under its terms. Marine delay in startup addresses a different financial interest and requires deliberate review of the delay trigger, insured party and expected income or debt-service exposure. An EPC contractor purchasing cargo insurance does not necessarily insure the developer’s future revenue.

Clarify who bears transit risk under the supply agreement and who would suffer the delay loss. Review the period of insurance, storage extensions, transshipment and inland legs. Ask whether delay protection requires damage recoverable under the underlying cargo policy and how exclusions, warranties or survey requirements affect both sections. A missed vessel or ordinary port congestion is not automatically an insured delay.

Test the schedule and financial assumptions

Consider an illustrative transformer damaged during unloading. Replacement takes longer than the project’s remaining float, but civil works are also behind schedule. The delay calculation must distinguish the effect of insured damage from delay that would have occurred anyway. Baseline schedules and contemporaneous updates are therefore important evidence, not merely project-management paperwork.

Review time deductibles, indemnity periods, insured financial measures and the treatment of mitigation costs. An accelerated shipment or temporary replacement may reduce delay but should be discussed within the policy’s consent and expense provisions. Loan penalties, liquidated damages and every financing cost should not be assumed to fall within a policy simply because they arise during delayed startup.

Coordinate marine and construction handovers

The project insurance plan should show when transit protection ends, when on-site construction protection attaches and how testing is treated. Temporary storage at a port or remote yard can create a gap if each party assumes the other has arranged it. Identify lifting and installation responsibilities at the transition.

Provide cargo lists, values, routes, transport methods, replacement lead times, project schedules and financial forecasts before placement. Update critical-item changes during procurement. After damage, preserve survey evidence, packing records and schedule impacts while coordinating immediate mitigation. The aim is a documented loss chronology that connects the physical transit incident to the particular delay claimed by the insured project interest.
