Dry Docking Clause in Ship Sale and Purchase: Underwater Inspection, Class, and Cost Allocation

In the second-hand ship sale and purchase market, the Dry-Docking Clause is one of the most important protective provisions in the Memorandum of Agreement (MOA). Its purpose is to allocate responsibility between Sellers and Buyers when the ship is inspected below the waterline before delivery, particularly in relation to the rudder, propeller, bottom plating, sea valves, tail-end shaft, and other underwater parts.

A ship may appear commercially acceptable during afloat inspection, document review, and class record examination, yet still contain hidden defects below the waterline. The Dry-Docking Clause gives the Buyers a mechanism to discover such defects before completion of the sale and determines who must pay if the Classification Society requires repairs to maintain the ship’s clean class status.

Purpose of the Dry-Docking Clause

The main purpose of the Dry-Docking Clause is to protect Buyers from taking delivery of a ship with class-affecting underwater defects, while also protecting Sellers from open-ended repair exposure for matters that do not affect the ship’s class. In practical terms, the clause creates a clear process for inspection, repair responsibility, and cost sharing.

In a typical second-hand ship sale, Sellers agree to place the ship in dry-dock at or near the delivery port if required under the agreed terms. Once the ship is docked, the underwater parts are inspected by the Classification Society’s surveyor. If the rudder, propeller, bottom, tail-end shaft, or other underwater parts are found broken, damaged, or defective in a way that affects the ship’s clean Certificate of Class, the Sellers must repair the defects at their own cost to the satisfaction of the Classification Society.

If no class-affecting defects are found, the cost allocation normally shifts to the Buyers, especially where the dry-docking was requested for the Buyers’ inspection purposes. This balance is central to the commercial logic of the clause.

Typical Dry-Docking Clause Wording

A dry-docking clause in a ship sale and purchase agreement commonly provides that the Sellers will dock the ship at the delivery port or at another agreed place. If the Classification Society finds that the rudder, propeller, bottom, or any other underwater part is broken, damaged, or defective in a manner affecting the ship’s clean class certificate, the Sellers must repair the relevant defects at their expense.

The clause may also allow the Buyers to require inspection of the tail-end shaft while the ship is in dry-dock. If the tail-end shaft is condemned or found defective in a way that affects the ship’s class, the Sellers must repair or replace it at their own cost. However, if the inspection is carried out merely at the Buyers’ request and the shaft is not defective, the Buyers may bear the cost of removing and reinstalling the shaft.

The precise wording differs between contracts and sale forms, but the commercial principle is usually the same: the party who requests or benefits from an inspection normally bears the cost unless a class-affecting defect is found, in which case the Sellers become responsible for the repair and associated dry-docking expenses.

Role of the Classification Society

The Classification Society plays a decisive role under the Dry-Docking Clause. The class surveyor is not simply a technical adviser for either Sellers or Buyers. The class surveyor acts as the independent authority whose findings determine whether the underwater condition of the ship affects class.

Buyers’ surveyors and Sellers’ superintendents may attend the dry-docking inspection and may express views on repair methods, but the Classification Society decides whether repairs are necessary for class purposes. If the class surveyor requires a repair before delivery, the Sellers normally must carry out that repair. If the class surveyor permits the ship to remain in class without qualification, the Sellers may not be obliged to perform additional work merely because the Buyers prefer a higher standard or more extensive repair.

This distinction is commercially important. A Buyer may wish to see full renewal, permanent repair, or replacement of a component. A Seller may prefer a lower-cost repair such as welding, fairing, dressing, or patching. The deciding issue is usually whether the Classification Society accepts the repair method as sufficient to preserve clean class.

Underwater Parts Covered by the Clause

The underwater inspection normally focuses on parts that cannot be properly examined while the ship is afloat. These may include the ship’s shell plating below the waterline, rudder, propeller, stern frame, sea chest, sea valves, bilge keels, anodes, thrusters, and other submerged fittings.

The clause is particularly important because damage to underwater parts can be expensive, operationally disruptive, and difficult to evaluate without dry-docking. Propeller damage, rudder defects, wasted plating, cracked welds, damaged sea valves, or tail-end shaft problems may affect the ship’s class, insurance, trading ability, and future dry-docking schedule.

For Buyers, the dry-docking inspection may be the first real opportunity to examine the ship below the waterline before paying the balance of the purchase price and accepting delivery. For Sellers, the clause limits the obligation to defects that are relevant to class, rather than every cosmetic or non-class item observed during inspection.

Tail-End Shaft Inspection

The tail-end shaft is a critical part of the ship’s propulsion system because it transmits power from the main engine through the shafting arrangement to the propeller. A defect in the tail-end shaft can be costly and may cause serious operational delay.

Many dry-docking clauses provide that the Buyers may request a tail-end shaft inspection during dry-docking. However, the cost of withdrawing and refitting the shaft may initially be for the Buyers’ account unless the Classification Society condemns the shaft or requires repair or replacement for class reasons.

If the shaft is found defective in a manner affecting the ship’s clean Certificate of Class, the Sellers may become liable for the repair or replacement cost and, depending on the wording, for the related dry-docking expenses. This makes the tail-end shaft provision a significant commercial point during negotiation, especially for older ships or ships with limited recent shaft survey history.

Who Pays for Dry-Docking?

Cost allocation under the Dry-Docking Clause depends on the result of the inspection and the wording of the contract. The costs may include dry-dock entry and exit fees, dock dues, tug and pilot expenses, class survey fees, underwater inspection costs, repair costs, and time-related expenses.

As a broad principle, Sellers usually pay the cost of taking the ship to and from the dry-dock and remain responsible for class-required repairs. Buyers may be responsible for dry-docking costs where the ship is docked at their request and no class-affecting defects are found. If class-affecting damage is discovered to the underwater parts or tail-end shaft, Sellers may be required to pay the repair costs and the dry-docking expenses.

It is important not to confuse the cost of moving the ship to the dry-dock with the cost of entering, remaining in, and leaving the dry-dock. These items may be treated differently under the contract. Well-drafted clauses should state clearly which party pays each cost and in what circumstances.

Buyers’ Protection Under the Dry-Docking Clause

For Buyers, the dry-docking clause is a key risk-control mechanism. It protects the Buyers from unknowingly purchasing a ship with expensive underwater defects that were not visible during afloat inspection. The clause also gives Buyers a practical means of confirming that the ship can be delivered with clean class and without hidden underwater deficiencies.

However, Buyers should not assume that every defect found in dry-dock will automatically be for the Sellers’ account. The usual test is whether the defect affects class or whether the Classification Society requires repair. If the ship remains in class without recommendation or qualification, the Buyers may not be able to force Sellers to perform extra work unless the contract expressly says so.

Buyers should therefore review the ship’s class records, recent survey status, dry-dock history, tail-end shaft survey status, underwater inspection records, and any outstanding recommendations before agreeing the final MOA wording.

Sellers’ Exposure Under the Dry-Docking Clause

For Sellers, the dry-docking clause can create material financial exposure. A ship that appears ready for delivery may suddenly require expensive underwater repairs if the class surveyor identifies defects affecting class. This may delay delivery, increase repair costs, and affect the closing schedule.

Sellers should therefore ensure that the clause does not create broader obligations than intended. If the Sellers’ obligation is limited to class-affecting defects, the wording should make this clear. Sellers should also consider whether temporary, class-approved repairs are sufficient, whether price deductions may be agreed instead of immediate repair, and whether any repair decision must be made by the Classification Society rather than by the Buyers alone.

Dry-Docking Clause and the Memorandum of Agreement

The Dry-Docking Clause should be read together with the wider MOA provisions, including inspection, class maintenance, delivery condition, cancellation, default, delivery documents, and price adjustment clauses. A dry-docking dispute can quickly become a delivery dispute if the ship cannot be repaired in time or if the parties disagree about whether the ship is deliverable.

In many second-hand ship sale transactions, the MOA will require the ship to be delivered with class maintained, free of average damage affecting class, and with trading certificates valid. The dry-docking clause supports this framework by creating a practical inspection and repair mechanism for underwater defects.

Where a standard form such as the Norwegian Saleform is used, the parties often negotiate rider clauses to reflect the ship’s age, trading pattern, class position, next scheduled dry-dock, and commercial urgency of delivery. Even small changes in wording can shift significant cost and risk between Sellers and Buyers.

Practical Issues During Dry-Docking

During the dry-docking process, disputes often arise over whether a defect is class-affecting, whether a repair must be permanent or temporary, whether the cost belongs to Sellers or Buyers, and whether delays caused by dry-dock congestion should affect the delivery window.

The parties should also consider who appoints and pays the attending surveyors, who controls repair quotations, whether Buyers may take independent measurements, whether Sellers may choose the repair yard, and whether the Buyers’ technical representatives may interfere with the repair programme.

Clear communication between Sellers, Buyers, class surveyors, ship managers, shipbrokers, and lawyers is essential. Poor coordination can delay delivery and create unnecessary disputes over relatively small repair items.

Dry-Docking Clause Example in Practice

Assume a bulk carrier is sold for delivery at an agreed port. The Buyers request dry-docking before delivery. The ship enters dry-dock and the Classification Society’s surveyor inspects the bottom, propeller, rudder, and sea valves.

If the surveyor finds only normal coating deterioration and no class-affecting damage, the Buyers may have to pay the dry-docking expenses according to the MOA. If the surveyor finds propeller damage that must be repaired before class can be maintained without qualification, the Sellers must pay for the repair and may also become responsible for the dry-docking expenses, depending on the wording.

If the Buyers also request a tail-end shaft inspection and the shaft is found sound, the Buyers may pay for withdrawing and refitting the shaft. If the shaft is condemned by class, the Sellers may be responsible for replacement or repair and the associated costs.

Why the Dry-Docking Clause Matters in Ship Sale and Purchase

The Dry-Docking Clause matters because it deals with one of the most expensive hidden-risk areas in second-hand ship transactions: the condition of the ship below the waterline. Unlike visible deck equipment, cargo holds, accommodation, machinery spaces, and certificates, underwater parts cannot be fully verified while the ship is afloat.

A well-drafted dry-docking clause gives Buyers confidence that class-affecting underwater defects will be dealt with before delivery. At the same time, it gives Sellers a defined standard and prevents Buyers from turning the delivery dry-docking into a general refurbishment exercise at Sellers’ expense.

For shipowners, shipbrokers, managers, and maritime lawyers, the clause is therefore not a minor technical provision. It is a central commercial term that can affect the price, delivery date, risk allocation, class status, and successful completion of the ship sale.

Conclusion

The Dry-Docking Clause in Ship Sale and Purchase sets out how underwater inspection, class-required repairs, tail-end shaft examination, and dry-docking costs are handled before delivery. Its importance lies in balancing the Buyers’ need to inspect hidden underwater parts against the Sellers’ need to avoid unlimited repair responsibility.

In every second-hand ship transaction, the parties should treat the dry-docking clause as a major commercial and legal provision. The clause should clearly state when the ship will be docked, who pays for dry-docking, who pays for repairs, what happens if class requires work, how tail-end shaft inspection is handled, and whether the ship can be delivered with any outstanding defects or deductions. Properly drafted, the clause reduces uncertainty and helps both Sellers and Buyers complete the sale with greater confidence.
