Exceptions in Time Charterparty
Exceptions clauses perform an important but carefully limited role in a time charterparty. They do not rewrite every promise made by shipowners and time charterers. Instead, they allocate responsibility for specified risks when performance is prevented, delayed, or affected by events such as fire, restraint by public authority, sea perils, machinery accidents, or navigational error.
In the New York Produce Exchange (NYPE) Charterparty Form, the main exceptions wording appears in Clause 16. The clause refers to act of God, enemies, fire, restraint of princes, rulers and people, dangers and accidents of seas, rivers, machinery, boilers and steam navigation, and errors of navigation, all of which are stated to be mutually excepted. Although the wording is familiar, its protection is narrower than it may first appear.
The Commercial Function of Clause 16 in Time Charterparty
Clause 16 is designed to relieve a party from liability where a specified event prevents or delays performance of a contractual obligation. It is not an automatic answer to every claim arising during the charter. A party relying on the clause must show that the loss, delay, or failure in performance falls within the actual language of the exception and that the exception is capable of applying to the obligation in question.
The wording is mutual. This means that the exceptions are available not only to shipowners but also to time charterers where the particular exception properly applies. If a time charterer is prevented by an excepted event from performing an obligation, the same clause may in principle assist the time charterer. However, mutual wording does not convert the clause into a general exemption from negligence or from specific undertakings in the charter.
The protection given by Clause 16 is especially restricted because the clause does not contain a broad negligence exception. It refers to errors of navigation, but English authority treats that wording as insufficient to protect negligent navigation. Wider protection may be available where the charter incorporates the United States Carriage of Goods by Sea Act through the Clause Paramount, but that is a separate route of protection and must be analysed separately.
How Exceptions Clauses Are Interpreted in Time Charterparty
Under English law, the meaning of an exceptions clause is determined by ordinary contractual construction. Courts examine the charter as a whole, the language chosen by the parties, the commercial setting, and the relationship between the printed form and any additional typed or negotiated clauses. Clear words are given commercial effect, but ambiguous exclusion wording is not stretched to remove liability that the parties have not clearly excluded.
The modern approach was explained in Photo Production v. Securicor, where the House of Lords emphasized that commercial contracts between experienced business parties should not be distorted by strained interpretation where the words are clear. Nevertheless, where wording is genuinely capable of more than one meaning, the narrower construction of an exemption from liability will usually be preferred as a last resort.
A printed exceptions clause will not normally override a more specific additional clause that imposes responsibility for a particular matter. If the parties have inserted a detailed typed provision, especially one dealing with the description, condition, capacity, or special function of the ship, the court is unlikely to treat the general printed exception as silently cancelling that specific responsibility. The decisions in The Brabant and The TFL Prosperity illustrate this approach.
Time Charterparty Clause 16 Is Not Limited to Loss of the Ship
The exceptions wording in Clause 16 is not confined to situations where the ship is lost. Although it follows wording dealing with the return of unearned hire if the ship is lost, the exceptions themselves are of general application. In The Oliva, an argument that the exceptions were limited by their position in the clause was rejected.
At the same time, the exceptions do not prevent the operation of the first sentence dealing with repayment of unearned hire after loss of the ship. If hire has been paid in advance but not earned because the ship has been lost, the repayment obligation is not avoided by relying on the mutual exceptions that follow.
The Relationship Between Clause 16 and U.S. COGSA
Where Clause 24 of the New York Produce Exchange (NYPE) Charterparty Form incorporates U.S. COGSA, the statutory defences may give shipowners much broader protection than Clause 16 itself. Section 4(2)(a), for example, protects against act, neglect, or default of the master, mariner, pilot, or servants of the carrier in navigation or management of the ship. That wording is wider than the Clause 16 reference to errors of navigation.
If the Clause Paramount is deleted, the charter may be left with the more limited wording of Clause 16. That can be a material change in risk allocation. Conversely, where U.S. COGSA is incorporated, Clause 16 may have limited practical importance for shipowners in many cargo-related matters, although it may remain important for time charterers or for obligations not fully covered by the statutory wording.
Act of God
The expression Act of God refers to events caused by natural forces that could not have been avoided by the exercise of reasonable care, skill, and precaution. Extraordinary storms, lightning, frost, and other overwhelming natural agencies may fall within the expression if they satisfy that test. The exception is not available where negligence contributes to the loss.
The central question is whether prudent and experienced maritime operators could reasonably have guarded against the event. If all ordinary and practical precautions were taken, but natural forces nevertheless overcame the ship or cargo operation, the exception may apply. If the loss resulted from want of care, defective preparation, poor maintenance, or negligent handling, the clause will not protect the party seeking to rely on it.
Enemies and Public Enemies
The exception for enemies is concerned with hostile action by enemies of the relevant state or states connected with the ship or the parties. It is not a general protection for every hostile, criminal, or violent act. The precise scope depends on the charter language and the legal context in which the issue arises.
Under U.S. COGSA, the corresponding expression is act of public enemies. That wording may include piracy in appropriate circumstances. However, where the relevant loss has been caused or materially contributed to by negligence, the exception will not ordinarily provide a defence.
Fire Under Time Charterparty Clause 16
The fire exception is an important example of the limited nature of the NYPE Clause 16 wording. The exception can protect against loss or damage caused by fire, but not where the fire was caused by the negligence of the party relying on the clause or that party's servants or agents. The decision in Polemis v. Furness Withy is a leading illustration of this limitation.
In that case, a fire followed after a plank was negligently dropped into the hold during unloading. The time charterers could not rely on the fire exception because the fire had been caused by the negligence of their stevedores. The case is significant because the exception was mutual, yet mutual protection did not excuse negligent conduct in the absence of clear words.
Where U.S. COGSA is incorporated, the fire exception may be wider. Section 4(2)(b) protects against fire unless caused by the actual fault or privity of the carrier. However, the carrier may still lose protection if a failure to exercise due diligence to make the ship seaworthy before and at the beginning of the voyage caused the fire. The principle is illustrated by Maxine Footwear v. Canadian Government Merchant Marine.
In addition, for a United Kingdom ship, statutory fire protection may be available under the Merchant Shipping Act 1995. That protection is also subject to important limits, particularly where the loss results from a personal act or omission committed intentionally or recklessly with knowledge that the loss would probably result.
The word fire requires actual combustion. Mere heating, without fire, is not enough. However, where fire occurs, damage caused by smoke or by water used to extinguish the fire may still be treated as damage by reason of fire. This distinction is commercially important in cargo claims and in disputes concerning the allocation of risk between shipowners and time charterers.
Restraint of Princes, Rulers and People
Restraint of princes, rulers and people covers forcible or compulsory interference by governmental or sovereign authority that prevents or impedes performance of the charter. It may include trade restrictions, customs or quarantine action, political seizure, and other official acts that effectively restrain the ship or cargo operation.
Physical force is not essential. A binding governmental order, even without immediate physical compulsion, may be sufficient if it decisively requires obedience and thereby prevents performance. Nor is the exception necessarily unavailable merely because the ship is outside the territory of the restraining state, provided the relevant party is subject to that state's jurisdiction and must obey its order.
The exception can also apply where the risk of restraint is already in being and a reasonable commercial person would regard the performance of the charter as likely to be affected if the intended course of action continues. This is why the exception may cover not only an actual detention but also a commercially justified response to an existing restraint.
There are important boundaries. The exception does not normally apply to action by rebels, guerrillas, or private groups that do not constitute the ruling power or executive authority of the country. It also does not ordinarily cover arrest under normal judicial process under English law, although U.S. COGSA expressly extends its corresponding wording to seizure under legal process.
The exception is also unavailable where the restraint results from negligence, or where the legal restriction was already in existence and known to the party seeking to rely on it when the charter was made. Known restrictions are part of the bargain unless the charter provides otherwise.
Dangers and Accidents of Seas and Rivers
The exception for dangers and accidents of seas and rivers covers maritime perils peculiar to navigation on seas or rivers that cannot be avoided by reasonable care. Severe weather, striking an iceberg, a sunken rock, or another ship, and unavoidable entry of seawater may fall within the exception if the event was not caused by negligence.
The exception is concerned with dangers of the sea, not every danger occurring on the sea. Fire and lightning, for example, are not normally treated as sea perils merely because they happen during a voyage. Rain is not a peril of the sea in itself. The distinction is between maritime risks inherent in sea or river navigation and ordinary events that merely occur while the ship is at sea.
The exception may also protect action reasonably taken to avoid or reduce sea peril. For example, closing ventilators to prevent seawater entering during heavy weather may fall within the protection if the resulting cargo damage was caused by a proper response to a sea peril and not by negligence.
U.S. decisions have sometimes taken a narrower approach to foreseeability in relation to perils of the sea. American cases often ask whether the weather was sufficiently violent, unusual, or unforeseeable for the relevant season and route. A storm may be severe, yet still regarded as expected in the North Atlantic winter if the evidence shows that such conditions were foreseeable.
Machinery, Boilers and Steam Navigation
The exception for machinery, boilers and steam navigation concerns physical risks associated with the operation of a mechanically propelled ship. Breakdown of an engine, disabling of a screw, or comparable mechanical accident may fall within the wording even if it occurs in calm water and fair weather.
As with the other exceptions, negligence remains a central limitation. If the machinery accident results from negligent maintenance, defective management, or failure to exercise the required care, the party relying on the exception may not be protected. The clause is not a general warranty that every mechanical difficulty is excused regardless of fault.
Errors of Navigation Under Time Charter
The phrase errors of navigation has a narrower effect under English law than many commercial readers might expect. It does not clearly exclude negligent navigation. Since there can be navigational errors that are not negligent, the wording is not treated as sufficiently clear to protect negligence. The decisions in The Satya Kailash and The Emmanuel C demonstrate this approach.
There must also be an error in navigation in the true sense, meaning an error in seamanship or navigation of the ship. A master's commercial choice to follow a slower route when the charter requires utmost despatch is not necessarily an error of navigation. In The Hill Harmony, the distinction between navigational judgement and compliance with employment orders became particularly important.
Where U.S. COGSA is incorporated, the statutory wording is wider because it refers to act, neglect, or default in navigation or management of the ship. That wording can protect against negligent navigation in a way that Clause 16 alone may not.
The Meaning of Mutual Exceptions in Time Charterparty
The words always mutually excepted make the listed exceptions available to both sides. Shipowners may rely on them when an excepted event prevents shipowners' performance, and time charterers may rely on them when an excepted event prevents time charterers' performance. The mutual nature of the clause is one of the commercial features of the New York Produce Exchange (NYPE) wording.
However, mutuality does not enlarge the substance of each exception. If the fire exception does not protect a negligent shipowner, it will not protect negligent time charterers either. If an exception is not wide enough to cover breach of a safe port undertaking, shipment of unlawful cargo, or shipment of excluded cargo, the fact that the clause is mutual does not change that result.
This point is especially significant where the immediate cause of loss may be an excepted peril but the deeper contractual breach is a specific undertaking by one party. In The Greek Fighter, for example, mutual exceptions did not assist in relation to breach of obligations concerning unlawful cargo or cargo presenting a risk of capture or seizure.
U.S. COGSA Section 4(2) Exceptions in Time Charterparty
Where U.S. COGSA is incorporated, Section 4(2) provides a detailed list of carrier defences. These include navigation or management of the ship, fire unless caused by actual fault or privity, perils of the sea, act of God, act of war, act of public enemies, arrest or restraint of authorities, quarantine restrictions, acts or omissions of the shipper, strikes, riots, saving life or property at sea, inherent vice, insufficiency of packing or marks, latent defects not discoverable by due diligence, and other causes without carrier fault or servant negligence.
These statutory exceptions are wider and more structured than the short NYPE mutual exceptions wording. They may protect shipowners in cargo-related disputes and in other contractual activities where the statute is incorporated into the charter. However, the burden and scope of each defence must still be considered carefully.
Section 4(3) of U.S. COGSA also provides that the shipper is not responsible for loss or damage sustained by the carrier or ship arising without the act, fault, or neglect of the shipper or its agents or servants. Its usefulness to time charterers is uncertain, especially where the time charterer is not the shipper or is itself acting as a carrier for the shipment.
Time Charterparty Clause 16 and Repayment of Unearned Hire
The exceptions in the second sentence of Clause 16 do not qualify the separate obligation to return unearned hire where the ship is lost. If advance hire has been paid but not earned, the mutual exceptions cannot be used to avoid repayment. The obligation is independent of the listed exceptions.
This distinction also shows why different clauses must be read according to their function. A clause dealing with loss of the ship and unearned hire is not the same as a clause allocating liability for delay, loss, or failure in performance caused by an excepted event.
Baltime Charterparty Clause 12: A Wider Shipowner Protection
The Baltime form uses a different and much wider exceptions structure. Clause 12 gives shipowners substantial protection against delay in delivery, delay during the charter, and loss or damage to goods on board, unless the relevant loss is caused by personal want of due diligence by shipowners or their manager in making the ship seaworthy, or by another personal act, omission, or default.
The second sentence of Baltime Clause 12 states in broad terms that shipowners are not responsible in any other case, even for damage or delay caused by neglect or default of their servants. Despite this broad wording, the House of Lords in The TFL Prosperity held that the clause did not protect shipowners from all forms of financial loss, and did not protect them against liability for breach of a detailed description of the ship.
This is a fundamental point. Even a wide exceptions clause must be read in its contractual setting. If a charter describes a ship with particular attributes, especially where those attributes are central to the intended trade, the shipowners cannot usually turn that detailed description into a non-binding statement of intention by relying on a general printed exception.
Baltime Exceptions and Delay in Delivery
Baltime Clause 12 does not protect shipowners against every possible delay in delivery. In The Helvetia-S, a newbuilding was not ready by the expected time because of construction delay. The court held that delay in construction was not the same thing as delay in delivery for the purposes of the clause. The wording was not read so widely as to shift that risk to the time charterers.
The decision demonstrates the importance of identifying the precise source of delay. A delay arising under a prior building contract or other arrangement to which the time charterers are not parties will not necessarily be treated as an excepted delay in delivery, unless the charter as a whole clearly allocates that risk to the time charterers.
Delay During the Time Charter Under Baltime
Baltime Clause 12 may protect shipowners from liability for delay during the charter period, including delay caused by servants or crew, if the claim falls within the clause and there has been no personal want of due diligence or personal default by shipowners or their manager. This may include certain cases where the master's conduct causes delay in prosecution of the voyage.
The protection is still not unlimited. If the delay is connected with a specific obligation that the shipowners have accepted in clear terms, or if the loss is outside the categories addressed by the clause, the exception may not apply. The court will read the charter as a single commercial instrument, not as isolated printed sentences.
Personal Want of Due Diligence in Time Charterparty
The phrase personal want of due diligence in Baltime Clause 12 is narrower than the Hague Rules due diligence obligation. It does not automatically make shipowners liable for every failure by servants, agents, or independent contractors. The word personal directs attention to the conduct of shipowners themselves or their manager, including the conduct of persons who represent the directing mind and will of the corporate organisation.
In The Brabant, the shipowners were not personally at fault for the crew's failure to clean coal residues from the holds, but a typed clause placed hold-cleaning risk and expense on the shipowners. That typed clause prevailed over the general printed exceptions wording. The case is a useful reminder that specific negotiated wording can displace broad printed protection.
The corporate meaning of personal fault has generated important authority. In Lennard's Carrying Co. v. Asiatic Petroleum, the House of Lords explained that a corporation acts through persons who represent its directing mind and will. Later cases such as The Lady Gwendolen, Tesco v. Nattrass, The Marion, and The Ert Stefanie examine how that concept applies to shipping companies and managers.
A company may be personally responsible through directors and, in appropriate circumstances, through senior managers who exercise functions that would otherwise belong to the board. Shipowners and managers must also maintain proper systems for the management, operation, and manning of their ships. Merely appointing subordinates is not always enough if the system itself is defective.
Where a crew member is incompetent and that incompetence results from personal failure by shipowners or managers to make proper enquiry before engagement, the protection of Baltime Clause 12 may be lost. Cases such as The Roberta and The Hongkong Fir show the seriousness of crew competence and seaworthiness issues in this context.
Baltime Charterparty Strike and Labour Exceptions
Baltime Clause 12 also contains protection for strikes, lockouts, stoppage, and restraint of labour. In this part of the clause, loss or damage can include financial loss as well as physical loss. However, negligence may still prevent reliance on the exception unless the claim is properly characterised as delay covered by the first sentence and there is no personal want of due diligence or personal default.
A strike is generally a concerted stoppage of work by workers to improve wages or conditions, protest a grievance, or support other workers. It need not affect every ship or every type of work. In The Laga, port workers refused to unload ships carrying coal in sympathy with French coal miners, and that was treated as a strike although other port work continued.
A refusal to work a particular shift may also be a strike even if the workers are not contractually obliged to work that shift. In The New Horizon, the refusal to work the night shift was held to be strike action because it was directed at improving working conditions. A breach of the workers' employment contracts is not essential.
Crew members may themselves be strikers where they withhold labour in pursuit of a grievance. However, where crew members merely interfere with stevedores without withholding labour required for the relevant cargo operation, the analysis may be different. The decision in Compania Naviera Bachi v. Hosegood illustrates this distinction.
A stoppage is broader than a strike and may include a refusal to work caused by fear of disease or other non-labour-dispute reasons. Where the word stoppage is used alone, it has sometimes been interpreted as requiring a complete stoppage of work. In Baltime, however, the wording includes partial or general stoppage, which broadens the possible scope.
Burden of Proof Under Baltime Charterparty Clause 12
Shipowners relying on Baltime Clause 12 must show how the relevant delay, loss, or damage arose and that it falls within the clause. They must also be able to show that the loss was not caused by personal want of due diligence or personal default where that issue is material. If shipowners cannot explain how the loss occurred, they may fail to bring themselves within the exception.
This burden is commercially significant because exceptions clauses are not self-proving. A party relying on an exception must usually provide the evidence needed to connect the loss with the protected cause and to exclude any disqualifying fault.
Misdescription of the Ship in Time Charterparty
A general exceptions clause will not normally protect shipowners against misdescription of the ship. Where the charter contains detailed warranties or descriptions of the ship's capacity, dimensions, speed, equipment, or suitability for a specific trade, those terms are usually treated as central promises. A broad printed exception is unlikely to erase them unless the wording unmistakably says so.
In The TFL Prosperity, the ship was described in detail as suitable for a particular roll-on, roll-off trade, but the free height under the main deck was less than stated. The House of Lords held that the exceptions clause did not protect the shipowners against the time charterers' financial losses caused by that misdescription. To hold otherwise would have made the detailed description commercially meaningless.
Where a misdescription is made during negotiations and induces the time charterers to fix the charter, statutory controls on exclusion of liability for misrepresentation may also become relevant. The shipowners may need to show that any clause excluding liability is fair and reasonable under the applicable legislation.
Paramount Clause in Baltime Charterparty
Where a Baltime Charterparty incorporates a Paramount clause, the effect depends on the wording used. In general, a properly incorporated Hague or Hague-Visby regime may override or limit the operation of Baltime Clause 12, especially in relation to cargo claims. The wider Baltime protection may then be replaced, for some purposes, by the more structured rules of the incorporated cargo liability regime.
In The Agios Lazaros, a reference to a Paramount clause without further qualification was held to incorporate the Hague Rules. Later authority, including Seabridge Shipping v. Orssleff's, treated similar wording with caution where the question was whether the Hague Rules or Hague-Visby Rules were intended. The practical lesson is that charter drafting should identify the intended regime expressly.
U.S. Law: Function of the Mutual Exceptions Clause in Time Charterparty
Under U.S. law, the mutual exceptions clause protects either party from liability to the other where performance of a covenant is prevented or delayed by one of the listed exceptions. The leading analysis appears in Clyde Commercial S.S. Co. v. West India S.S. Co., where the court explained that mutual exceptions operate for shipowners and time charterers alike.
The clause does not excuse independent obligations unless performance of those obligations has actually been prevented by an excepted cause. It also does not modify the shipowners' seaworthiness warranty unless the charter clearly does so. Any loss caused by unseaworthiness, or by failure to exercise due diligence where that is the relevant standard, will not ordinarily be excused by the mutual exceptions clause.
U.S. law also treats the off-hire provision separately from the mutual exceptions clause. If an off-hire event under Clause 15 occurs, the time charterers may be excused from paying hire even if the same event could also be described as a mutual exception. In Clyde Commercial S.S. Co. v. West India S.S. Co., the court treated the off-hire categories as absolute for that purpose.
U.S. Law: Act of God in Time Charterparty
American law generally requires an act of God to arise from natural causes without human intervention. The event must be overwhelming and unanticipated in a way that makes it unfair to charge the carrier with responsibility for failing to guard against it. If negligence contributes to the loss, the defence fails.
The exception also does not remove the continuing duty to take reasonable steps to protect property and prevent further loss after the event occurs. A party cannot simply point to a natural event and ignore the practical steps that a prudent operator should still have taken.
U.S. Law: Fire and the Fire Statute in Time Charterparty
Under U.S. law, fire requires ignition or combustion. Heat and smoke without combustion are not usually enough, although once a fire exists, damage caused by smoke, water, or other firefighting measures may be treated as fire damage. This approach broadly parallels the English distinction between fire and mere heating.
The U.S. Fire Statute and COGSA fire exception may give shipowners a wider defence than an ordinary charter fire exception. A shipowner is generally not liable for cargo loss caused by fire unless the fire was caused by the shipowner's design, neglect, actual fault, or privity. Negligence of the master or crew will not necessarily be treated as the personal fault of a corporate shipowner.
In many U.S. fire cases, once the shipowner proves that the loss was caused by fire, the burden shifts to the cargo claimant to prove the shipowner's personal fault or privity, although there is authority taking a different view in some jurisdictions. The allocation of the burden of proof can be decisive where the cause of the fire is uncertain.
U.S. Law: Restraint of Princes in Time Charterparty
American law treats restraint of princes as an exercise of sovereign power that prevents performance. It may include official blockade, well-founded apprehension of capture, and official quarantine. It does not extend to every government-related difficulty or to unauthorized acts by officials acting outside their authority.
The key requirement is official governmental action. In The Andros Island, precautionary recommendations issued after hostilities between Greece and Turkey over Cyprus were not treated as binding government orders. Similarly, threatened refusal by a minor department may not be enough unless it represents official government action.
A regular court order in ordinary legal proceedings has been held not to amount to restraint of princes in some U.S. arbitration decisions. However, specific charter wording or incorporated statutory wording may alter that result, particularly where the relevant clause expressly includes seizure under legal process or interference of authorities.
U.S. Law: Sea Perils in Time Charterparty
U.S. law recognises that perils of the sea are broader than act of God and may include more than purely natural events. However, American decisions often focus closely on whether the conditions were foreseeable for the route, season, and circumstances. The weather must usually be sufficiently severe or exceptional to qualify.
In some cases, violent weather has been accepted as a peril of the sea even if storms are possible at that season. In others, heavy North Atlantic winter weather has been treated as foreseeable and therefore insufficient. The evidence of weather, route, ship condition, cargo stowage, and crew conduct is often critical.
A peril of the sea defence will fail if the loss could have been avoided by reasonable skill and diligence. Improper stowage, unseaworthiness, or negligent management may defeat the exception even where heavy weather was encountered during the voyage.
U.S. Law: Machinery and Navigation in Time Charterparty
American cases treat machinery exceptions as referring to the ship's machinery as a whole. In The Toledo, a crankshaft web fracture was treated as an accident of machinery, and the shipowner received the benefit of the mutual exceptions clause where the latent defect was not discoverable by due diligence.
The U.S. treatment of navigation errors is generally wider than the English treatment of the NYPE wording, especially where U.S. COGSA or the Harter Act applies. However, if unseaworthiness caused or contributed to the navigational error or the resulting loss, the defence may be unavailable.
Practical Drafting Lessons
The practical lesson from the authorities is that exceptions clauses should not be treated as boilerplate of little commercial consequence. Their wording determines whether a party is protected against delay, fire, sea perils, machinery accidents, governmental restraint, labour disputes, or navigation-related losses. Small differences in wording can materially change the allocation of risk.
Parties should state expressly whether negligence is excluded, whether U.S. COGSA or another cargo regime is incorporated, whether arrest or legal process is covered, whether strike and labour wording is intended to cover partial stoppage, and whether ship description clauses are to remain absolute. If special risks are commercially important, they should be addressed directly rather than left to general printed exceptions.
The charter should also make clear how exceptions interact with off-hire, seaworthiness, due diligence, safe port obligations, lawful cargo undertakings, cargo handling responsibility, and repayment of unearned hire. These are separate legal mechanisms, and a general exception will not always control them.
Commercial Effect of Exceptions in Time Charter Disputes
In practice, an exceptions clause is rarely analysed in isolation. The dispute may involve off-hire, damages, indemnity, cargo liability, seaworthiness, misdescription, frustration, or withdrawal. The first task is to identify the obligation allegedly broken. The second is to ask whether performance of that obligation was prevented or affected by a specified exception. The third is to consider whether negligence, personal fault, an overriding typed clause, or an incorporated statutory regime changes the result.
For shipowners, the clause may protect against certain liabilities but will not excuse every failure in performance. For time charterers, the mutual wording may provide useful protection in some circumstances, but it will not relieve liability for core undertakings such as unsafe employment, unlawful cargo, or obligations expressly accepted elsewhere in the charter. The strength of the clause depends on precise drafting and careful connection between the loss and the excepted event.
A well-drafted exceptions clause gives commercial certainty by identifying which risks are carried by each side. A poorly drafted clause can create uncertainty, especially where printed wording, typed additions, and statutory incorporation are not aligned. For that reason, exceptions in a time charterparty must be read with close attention to the complete charter structure, not merely the familiar list of protected events.
