Global infrastructure projects—from power plants to new manufacturing units—rely on the timely delivery of massive, specialized equipment known as project cargo. When a critical component is damaged or lost at sea, the resultant delay can halt the entire construction timeline, leading to devastating financial losses far exceeding the value of the damaged item itself. This is the precise risk addressed by the Marine DSU Policy (Delay in Start-Up), a vital component of marine DSU insurance for project cargo. It shifts the focus from physical damage (covered by standard cargo insurance) to the consequential loss of revenue.

What is a Marine DSU Policy (Delay in Start-Up)?
A Marine DSU Policy is a specialized kind of consequential loss insurance known as Advance Loss of Profits (ALOP). Unlike regular marine cargo insurance, which only covers the cost of repairing or replacing the damaged item, the Marine DSU Policy provides compensation to the project owner for any financial loss caused by the delay in the project’s commercial operation date. This coverage can be particularly important for high-stakes ventures such as new refineries or offshore wind farms, where one large item (a large transformer or a turbine blade) may take 18-24 months to remanufacture and reship. Losses that can be considered typically include:
Loss of Gross Profit: The profit the project could have identified before the delay (the actual loss of revenue the project would have earned during the delay).
Standing Charges: Costs incurred that are consistent (debt service, interest, salaries) if the project slows or even comes to a complete standstill.
Increased Cost of Working (ICOW): The incurred costs that were incurred to specifically prevent or minimize any delays (e.g., air freighting to replace a part, increased labor cost, etc.).
The Project Cargo Imperative in Developing Economies
In rapidly growing economies such as India, large infrastructure development projects are executed according to strict timelines and complex financing arrangements. Project cargo must sail past multiple logistical hurdles in port and inland transit. When a loss occurs, the financial penalty of missing the "commercial operation date" (COD) can result in an overwhelming loss to the project owner or breach the agreed contracts with lenders. As a result, the absolute necessity is to secure reliable marine DSU insurance for project cargo to protect against financial loss due to logistical or transit delays, as well as other risks.
Marine DSU Insurance for Project Cargo: What it Covers
The fundamental trigger for a claim under a Marine DSU Policy is a physical loss or damage event, covered by the primary Marine Cargo policy, that results in a delay to the project's completion.
Loss Event (Marine Cargo Policy) | Resulting Loss (Marine DSU Policy) |
Collision: A Vessel carrying a critical piece of machinery sinks or is disabled. | Loss of anticipated revenue during the 18 months required to manufacture a replacement. |
Heavy Weather Damage: The Project component is swept overboard or structurally damaged during transit. | Fixed monthly debt repayments that accrue during the extended construction phase. |
General Average: The Ship is involved in a salvage operation, delaying delivery by six months. | The increased working costs required to compress the remaining construction timeline. |
The key takeaway is that the Marine DSU Policy follows the "fortunes" of the underlying Marine Cargo policy—if the physical damage is not covered, the financial delay is not covered.
The Essential Link: Marine Risk to Financial Loss
A common point of risk is the interface between the marine portion (covered by the Marine DSU Policy) and the construction/erection phase (covered by an Erection All Risks or CAR policy). marine dsu insurance for project cargo often explicitly covers the transit phase until the cargo is safely erected at the final site. Project owners must ensure their insurance program aligns the DSU coverage with the Critical Path schedule of the project, identifying "Critical Items" that, if delayed, will certainly postpone the COD. Insurers often mandate a Marine Warranty Surveyor for these critical items to reduce the inherent risk and ensure the viability of the Marine DSU Policy cover.
Underwriting the Timeline: Key Risk Factors
Underwriters evaluating the premium for marine dsu insurance for project cargo scrutinize factors beyond just the voyage route. They focus heavily on the financial and logistical aspects:
Critical Path Analysis: Is the component truly critical? If a delay in its arrival won't affect the COD, the DSU exposure is low.
Manufacturing/Remanufacturing Time: Components that take longer to replace or repair (e.g., custom-built turbines) attract higher DSU premiums.
Financial Structure: The level of debt and the profitability forecast determine the Sum Insured (the maximum exposure).
Deductible/Waiting Period: The policy contains a time excess (e.g., 60 or 90 days), representing the period of delay the owner self-insures before the Marine DSU Policy kicks in.
Best Practices for Mitigating DSU Claims
Align the Policies: Ensure the indemnity period, sum insured, and deductibles of the Marine DSU Policy perfectly match the underlying Cargo and Erection All Risks policies.
Detailed Critical Item List: Provide underwriters with a transparent list of all items designated as critical, including their replacement lead times.
Mandate Surveys: Always employ a Marine Warranty Surveyor for critical item transit, as this often acts as a warranty in the marine dsu insurance for the project cargo contract.
Quantify the Loss: Clearly calculate and justify the Gross Profit figure used for the sum insured to avoid underinsurance.
FAQs:
Q1: What is the main difference between a standard Marine Cargo policy and a Marine DSU Policy?
A: A standard Marine Cargo policy covers physical damage to the cargo (e.g., the cost to replace a damaged turbine). The Marine DSU Policy covers the consequential financial loss (lost profits, fixed costs) incurred by the project owner because the physical damage caused a delay to the project's commercial start date. The Marine DSU Policy relies on the Cargo policy claim to be activated.
Q2: Who typically purchases the marine DSU insurance for project cargo, and why?
A: The Marine DSU Policy is purchased by the Project Owner (the principal) or the Financiers/Lenders. This is because they are the ones with the direct insurable interest in the project’s revenue generation and fixed costs (like loan repayment). Contractors are typically excluded, as they do not bear the risk of post-completion operating losses, making this coverage essential for securing project financing.
Q3: Can a delay caused by a labor strike or poor performance trigger a Marine DSU Policy claim?
A: No. The Marine DSU Policy is explicitly triggered only by a delay resulting from an insured physical loss or damage event (such as a collision or fire) that is covered under the primary marine cargo policy. Delays caused by non-physical factors, such as contractor insolvency, labor disputes, changes in governmental regulations, or general project cargo scheduling issues, are standard exclusions and will not activate this marine dsu insurance for project cargo coverage.
Q4: What is the "Deductible" in a Marine DSU Policy?
A: The deductible in a Marine DSU Policy is a time excess, usually expressed in days (e.g., 30, 60, or 90 days). It represents the initial period of delay that the project owner must absorb before the insurance payout begins. For example, if the delay is 120 days and the deductible is 60 days, the insurer covers the financial loss for the remaining 60 days. This time deductible applies to the aggregate period of delay caused by the insured event.
Q5: How does the Sum Insured for a Marine DSU policy differ from the cargo values?
A: The Sum Insured for a Marine DSU Policy is the maximum financial loss the insurer will pay for the entire delay period, calculated as the estimated Gross Profit (Net Profit plus Fixed Costs) over the indemnity period. This value is typically much higher than the actual value of the project cargo itself. The marine dsu insurance for project cargo must use an accurate projection of future earnings to avoid costly underinsurance. A specialized provider like BTW IMF can help ensure your marine DSU insurance for project cargo uses an accurate projection of future earnings to avoid costly underinsurance.
The Marine DSU Policy is mandatory for critical infrastructure projects. While cargo insurance covers physical loss, DSU covers the catastrophic financial delays—lost profits and fixed costs—caused by transit mishaps. It is the essential specialized cover that protects a project's entire commercial timeline and secures its financial viability.
