Shipbuilding Contract: What Buyers Must Check

Before signing a commercial shipbuilding contract, buyers must verify the shipyard’s financial and technical capability, the vessel’s detailed specification and class rules, the payment and delivery schedule, and the dispute resolution and warranty terms. This article explains each critical check in depth so you can negotiate a contract that protects your investment.

Formula

The calculator above estimates the financial impact of a delivery delay using a typical liquidated damages (LD) clause. The formula is:

LD amount = LD rate per day × number of days delayed

Where:

• LD rate per day – the daily sum the shipyard pays you for each day of late delivery (often 0.05%–0.1% of the contract price).
• Number of days delayed – the actual days beyond the contractual delivery date.

In the calculator, the LD rate is fixed at 0.5 million USD per month (about 0.1% of a 50 million USD vessel per month). Adjust the contract price and delay to see the total cost.

Worked Example

Using the default values: contract price = 50 million USD, delay = 6 months.

1. LD per month = 0.5 million USD (assumed from the contract).
2. Total LD = 0.5 × 6 = 3 million USD.
3. Total cost = 50 + 3 = 53 million USD.

The calculator shows LD = 3.00 million USD and total = 53.00 million USD.

Why the Shipyard’s Financial Health Matters

A shipyard that goes bankrupt mid-construction can leave you with an incomplete hull and lost progress payments. Check the shipyard’s audited financial statements, order book, and credit rating. Look at how many vessels they have delivered in the last five years and whether any deliveries were significantly late. A yard with a thin order book may be desperate for cash, while one with too many orders might delay yours. Ask for bank guarantees or refund guarantees for your advance payments – these are separate from performance guarantees and protect your prepayments if the yard defaults.

Technical Specification and Class Rules

The contract’s specification is the heart of the deal. It must include the vessel’s dimensions, deadweight, speed, fuel consumption, cargo capacity, and all major equipment (main engine, generators, cranes, navigation systems). Crucially, it must state which classification society (e.g., DNV, ABS, Lloyd’s) will certify the vessel and which rules and regulations apply (SOLAS, MARPOL, IMO Tier III emissions). Insist on a “class approval� clause that requires the vessel to be built to the latest class rules in force at the time of contract signing – otherwise the yard might use older, cheaper standards. Also specify the design temperature, sea margins, and any owner’s extras (e.g., bow thruster, scrubber, shore power connection).

Payment Schedule and Milestones

Commercial shipbuilding contracts typically split payments into milestones: 10–20% on signing, 10% on steel cutting, 10% on keel laying, 20% on launching, and the final 40–50% on delivery. Each milestone must be tied to a verifiable event, not just a date. For example, “keel laying� should be defined as the actual placement of the first block in the drydock, with a surveyor’s certificate as proof. Avoid large upfront payments – the more you pay before delivery, the greater your risk. Ensure the contract states that each milestone payment is due only after the buyer (or their representative) has inspected and approved the completed work. Also include a provision for interest on late payments by the yard, and a right to suspend payments if the yard misses a milestone by more than a set number of days.

Delivery Date and Liquidated Damages

The delivery date is the single most commercial term. The contract must define “delivery� – usually when the vessel is afloat, completed, and ready for sea trials, and the buyer accepts it. It should also state what happens if the yard is late. A typical LD clause is 0.05% of the contract price per day, capped at 5–10% of the total price. If the delay exceeds a certain period (e.g., 180 days), the buyer may have the right to cancel and claim a refund. Conversely, the yard may offer a bonus for early delivery – but be careful: early delivery can disrupt your crew and charter arrangements. Also check the “force majeure� clause – it should list specific events (war, natural disasters, government actions) and not be a blanket excuse for any delay. The contract should require the yard to notify you within a set time of any event that may delay delivery.

Warranty and Defect Liability

After delivery, the yard is usually liable for defects in design, materials, and workmanship for a period of 12–24 months. The warranty should cover both the hull and machinery, and the yard must agree to repair or replace defective parts at its own cost, including drydocking expenses if needed. Check the notification procedure – you must typically report defects in writing within a set period (e.g., 14 days) after discovery. The contract should also state that the warranty does not cover normal wear and tear, damage from misuse, or defects caused by the buyer’s own repairs. For major items like the main engine, the warranty may be passed through from the engine manufacturer – ensure you get the manufacturer’s warranty certificates.

Dispute Resolution and Governing Law

Commercial shipbuilding contracts often involve parties from different countries. The governing law clause determines which country’s courts will interpret the contract – choose a neutral jurisdiction with established maritime law, such as English law or New York law. The dispute resolution clause should specify arbitration (e.g., London Maritime Arbitrators Association, Singapore Chamber of Maritime Arbitration) or litigation in a named court. Arbitration is usually faster and more confidential than court proceedings. The contract should also state the seat of arbitration and the language of proceedings. Include a clause that allows either party to refer a dispute to an expert (e.g., a naval architect) for technical issues before going to arbitration – this can save time and money.

Frequently Asked Questions

What is a refund guarantee and why do I need it?

A refund guarantee is a bank guarantee that ensures you get back your advance payments if the shipyard fails to deliver the vessel or goes bankrupt. It is usually issued by a first-class bank and covers the amounts you have paid before delivery. Without it, you could lose your prepayments if the yard defaults.

Can I change the specification after signing?

Yes, but any change will likely affect the price and delivery date. The contract should have a “variation order� procedure that allows you to request changes in writing, with the yard providing a revised price and schedule. Be aware that changes made late in construction are more expensive and can delay delivery.

What is a “force majeure� clause?

It is a clause that excuses a party from performing its obligations due to events beyond its control, such as war, natural disasters, or government actions. In shipbuilding, it often excuses the yard from liability for delays caused by such events. You should ensure the list is specific and does not include ordinary business risks like labor strikes or supplier delays.

How long does a typical shipbuilding contract take to negotiate?

Negotiation can take anywhere from 3 to 12 months, depending on the complexity of the vessel and the parties’ experience. Standard contracts like BIMCO’s NEWBUILDCON provide a good starting point, but you will still need to negotiate technical specifications and payment terms.

What happens if the vessel does not meet the specified speed or fuel consumption?

The contract should include performance guarantees with tolerances (e.g., speed within 0.5 knots, fuel consumption within 5%). If the vessel fails to meet these on sea trials, the yard must remedy the deficiency or pay damages. In severe cases, the buyer may have the right to reject the vessel.

Do I need a lawyer to review the contract?

Yes, absolutely. Shipbuilding contracts are complex and governed by maritime law. A lawyer experienced in shipbuilding transactions can help you negotiate fair terms and avoid pitfalls. The cost of legal advice is small compared to the value of the vessel.
