Safe Port (SP) and Safe Berth (SB) Under a Time Charterparty

Safe Port (SP) and Safe Berth (SB) Under a Time Charterparty

Safe port and safe berth obligations are central to the commercial structure of a time charterparty. Under a time charter, the charterers normally control the commercial employment of the ship and decide where the ship will load, discharge, bunker, wait, or perform cargo-related operations. That freedom is not unlimited. Charterers must exercise their employment rights within the contractual trading range and must not direct the ship to a port, berth, anchorage, canal, river passage, or place that is unsafe for the particular ship at the relevant time.

In the traditional New York Produce Exchange (NYPE) wording, the ship is to be employed in lawful trades between safe ports within the agreed geographical limits. The older form contains a long list of permitted and excluded areas, while NYPE 93 modernises the structure by leaving the trading range to be completed by the parties and by referring more directly to safe ports and safe places. Whatever form is used, the commercial purpose is the same: charterers may choose the employment, but the risk of selecting an unsafe place is not transferred to owners unless the charter clearly says so.

The Commercial Meaning of a Safe Port (SP)

The classic safe port test asks whether the particular ship can reach, use, and leave the port during the relevant period without being exposed, in the absence of an abnormal occurrence, to danger that cannot be avoided by ordinary good navigation and seamanship. This is a practical and commercial test. It is not enough to ask whether many ships can use the port safely; the port must be safe for the specific ship, with her size, draft, cargo condition, equipment, trading requirements, and operational circumstances.

A port is not unsafe merely because navigation requires care. Most ports involve tides, currents, narrow channels, swell, weather windows, bars, buoys, pilots, tugs, or local procedures. Those features do not make a port unsafe if an ordinarily competent master, supported by ordinary navigational skill and proper local systems, can manage the risks. The port becomes unsafe when the danger remains even after ordinary good seamanship is exercised, or where safe use depends on exceptional skill, unusual luck, or systems that are absent or inadequate.

Safety may be affected by physical conditions, such as shoals, ice, defective fenders, insufficient water, unreliable holding ground, narrow approaches, submerged obstructions, or inadequate sea room. Safety may also be affected by non-physical conditions, including war, political violence, seizure risks, sanctions-related detention, confiscation, rebellion, blockade, or other governmental or military interference. A port may therefore be physically safe but politically unsafe, or politically calm but physically unsuitable for the ship ordered there.

Temporary Dangers and Ordinary Waiting Time

A port is not unsafe simply because the ship must wait before entering, loading, discharging, or leaving. A ship may have to wait for tide, daylight, pilotage, weather improvement, berth availability, ice conditions, or traffic clearance. Temporary waiting of this kind is part of ordinary maritime trading and does not by itself breach a safe port obligation.

The position changes where the temporary danger is not merely a normal and evident delay, but exposes the ship to danger that cannot be safely managed. A port may be unsafe if ships are liable to be trapped by sudden weather, unreliable holding ground, defective warnings, inadequate tugs, insufficient manoeuvring space, or hidden navigational hazards. A short-lived danger may therefore be legally significant if the master has no effective warning or no safe means of avoiding it.

Delay may also amount to unsafety if it is so serious that it defeats the commercial adventure. The threshold is high. Ordinary congestion, a few days of ice delay, or a temporary obstruction will not usually make a port unsafe. The delay must be inordinate in relation to the nature and duration of the charter or voyage. In time charter analysis, the duration of the charter, the expected trading pattern, and the commercial consequences of the delay all matter.

Safety for the Particular Ship

The safe port undertaking is not an abstract promise that a port is generally safe. It is a promise that the port is safe for the particular ship ordered there. A port that is perfectly suitable for smaller ships may be unsafe for a larger ship. A berth that is safe for a shallow-draft ship may be unsafe for a heavily laden ship. A river port may be safe for a ship in ballast but unsafe for the same ship when laden, or safe inbound but unsafe outbound after discharge because of reduced draft and air-draft limitations.

The ship must be able to enter, remain, work cargo if required, and depart safely in the condition in which she is expected to use the port. The analysis includes the ship’s length, beam, draft, air draft, manoeuvring characteristics, cargo condition, ballast condition, mooring requirements, tug requirements, and the navigational circumstances that will exist when the ship is there.

When a ship is ordered to a port that can be used only by lightening cargo, removing parts of the ship’s structure, waiting for unusual assistance, or taking extraordinary precautions outside ordinary seamanship, the port may be unsafe for that ship. The same applies where the only available berth exposes the ship to contact with hidden obstructions, defective fenders, inadequate water depth, or insufficient sea room for emergency departure.

Safety of the Approach to the Port

The obligation of safety is not limited to the berth or the formal geographical boundary of the port. The ship must be able to reach the port safely. If the approach channel, river passage, canal, bar, pilotage route, or compulsory access waterway exposes the ship to danger that cannot be avoided by good navigation and seamanship, the port may be unsafe.

This principle is especially important for river ports and ports served by long approach channels. A dangerous obstruction many miles from the berth may still be a feature of the port if there is no alternative route by which the ship can reach or leave the port. The distance from the port does not by itself defeat the claim. What matters is whether the approach is an unavoidable part of using the nominated port and whether the danger is sufficiently connected with that port’s accessibility.

Approach safety may depend on accurate charts, proper buoyage, working lights, competent pilotage, traffic control, dredging systems, hydrographic monitoring, tug availability, ice management, convoy arrangements, or warnings about underwater dangers. If the port lacks a reasonable system to detect and communicate hazards in an approach channel, the port may be unsafe even if the specific obstruction was not known to the charterers when the ship was ordered there.

Safety While the Ship Is in Port

A safe port must also be safe for use. It is not enough that the ship can enter safely. The ship must be able to remain, load, discharge, bunker, wait, shift, or perform the required operation without being exposed to unacceptable danger. The port’s berths, anchorages, moorings, fenders, dolphins, buoys, tugs, pilots, weather-warning systems, emergency procedures, and sea room may all be relevant.

A port may remain safe even though ships must interrupt cargo operations and leave during particular weather. Many exposed ports operate on that basis. The port will be safe if the weather risk is known or reasonably predictable, the master receives adequate warning, pilots and tugs are available when required, and the ship has enough sea room to leave before danger develops. The port will not be safe if the ship may be trapped by sudden weather, insufficient warning, congestion, unavailable tugs, or lack of manoeuvring room.

Local systems are therefore critical. A port that depends on ships leaving during bad weather must have practical arrangements that enable departure in time. Weather forecasting alone may not be enough if pilots cannot attend, tugs are unavailable, other ships block the fairway, or the ship cannot safely clear the berth before the danger becomes unavoidable.

Safety on Departure

The safe port undertaking covers departure as well as entry and use. A port is unsafe if the ship can enter and discharge safely but cannot leave safely after cargo operations. This can arise where a ship’s draft changes after discharge, where air draft prevents outbound passage under bridges, where shoaling makes departure unsafe, where ice blocks the exit, where a river channel has become hazardous, or where the berth can be approached but not safely cleared.

Departure safety is judged in the context of the particular ship and the ordinary route she must use. If departure depends on local recommendations about maximum draft, channel depth, tide, ice, or traffic control, the system providing that information must operate effectively. A port may be unsafe where the formal information appears adequate but the practical system fails to monitor changes or update ships in time.

Political and War-Related Unsafety

Physical danger is not the only form of unsafety. A port may be unsafe where the ship faces a real risk of confiscation, seizure, attack, detention, blockade, hostile military action, unlawful governmental interference, or politically driven obstruction. The relevant danger must be connected with the port or its approach, not merely with the general political climate of the country or region.

The risk must also be more than a remote or speculative possibility. Sporadic violence elsewhere, general regional tension, or the fact that hostile action could theoretically occur may not make every port in the area unsafe. The political danger must have become a normal characteristic of the nominated port or its necessary approach at the relevant time. A sudden and exceptional attack may be treated as an abnormal occurrence rather than proof that the port was unsafe when nominated.

War risk clauses may alter this analysis. Some clauses give owners or the master the right to refuse dangerous war-zone employment, follow government or underwriter instructions, claim additional premiums, or discharge cargo elsewhere. Other clauses may allocate war risks in a way that affects safe port liability. Whether a war clause displaces or modifies the safe port obligation depends on the wording of the particular charter. Payment of extra war risk premium by charterers does not automatically mean that charterers are free to nominate unsafe ports without liability.

Abnormal Occurrences

The charterers’ safe port obligation does not make charterers insurers against every casualty that happens at a port. If the port is otherwise safe but the ship is damaged by an isolated, abnormal, and extraneous event, charterers will not usually be liable under the safe port undertaking. Examples may include an exceptional storm unrelated to the ordinary characteristics of the port, a one-off mistake by a competent pilot within an otherwise adequate system, sudden failure of lights caused by an external attack, or negligent navigation by another ship.

The concept of abnormal occurrence must be applied carefully. A danger is not abnormal merely because it is unusual in the long history of the port. If the danger exists for long enough, or arises from conditions that have become part of the port’s operational set-up, it may become a temporary characteristic of the port. Defective fenders, missing buoys, prolonged ice, recurring military attacks, unreliable holding ground, or repeated channel problems may all become relevant characteristics if they exist at the time when the ship is ordered or when the ship must use the port.

The key distinction is between a danger arising from the port’s qualities, systems, conditions, or prevailing circumstances and a casualty caused by a wholly external event that is not part of the port’s normal or temporary character. Only the former normally supports an unsafe port claim.

Prospective Safety at the Time of Nomination

The charterers’ primary obligation is judged when the order is given. At that moment, the nominated port must be prospectively safe for the ship at the future time when the ship is expected to reach, use, and leave it. The port does not have to be safe at the exact instant of nomination if a temporary danger will clearly have ended by the time the ship arrives. Conversely, the charterers are in breach if the port appears prospectively unsafe for the ship’s intended call, even if the ship has not yet suffered damage.

This does not mean that charterers are liable for every later change. If the port was prospectively safe when nominated and later becomes unsafe because of an unexpected abnormal event after the ship arrives, charterers may not have breached the primary safe port obligation. The famous Basrah example illustrates this principle: a port may be safe when ordered and when reached, but later become unsafe through a sudden war event that traps the ship after it is too late to leave.

However, later events may still be relevant as evidence. If a later casualty reveals that a dangerous condition already existed when the order was given, that later event may help prove that the port was prospectively unsafe from the outset. The later event is not used to impose hindsight liability; it is used to illuminate the real condition of the port at the time of nomination.

The Charterers’ Secondary Obligation

Where a port is safe when nominated but becomes unsafe while the ship is still able to avoid the danger, charterers come under a further obligation to cancel or vary the original order and give fresh safe orders. If the ship is still en route, charterers must not insist that she proceed into a port that has become unsafe. If the ship is already in port but can still leave before danger becomes unavoidable, charterers must not require her to remain exposed to the danger.

This secondary obligation reflects the limits of the owners’ consent under the time charter. Owners have agreed to let charterers employ the ship within the charter’s lawful and safe trading framework. Owners have not agreed to expose the ship to an unsafe port simply because an earlier order was valid when first given. Once the factual basis changes, the employment order may cease to be one that the master must obey.

Absolute Warranty and Due Diligence Clauses Under a Time Charterparty

In the absence of limiting wording, the safe port obligation is normally an absolute warranty. The question is not whether charterers acted carefully, made reasonable enquiries, or honestly believed the port was safe. The question is whether the port was in fact prospectively safe for the ship. If the port was unsafe, charterers may be liable even though the danger was unknown to them and even though they were not negligent.

Some charter forms replace this absolute promise with a due diligence obligation. The Shelltime forms, for example, may require charterers to use due diligence to ensure that the ship is employed only between and at safe places, while excluding a full warranty of safety. Under such wording, charterers are liable only if they failed to take reasonable care to establish that the nominated place was safe.

The difference is commercially important. Under an absolute safe port warranty, innocent nomination of an unsafe port can still create liability. Under a due diligence clause, owners must prove that charterers failed to act with the required care. However, unqualified safe port wording in a fixture recap may override or sit uneasily with due diligence wording in a printed form. The final answer depends on construing the full charterparty.

Orders to an Unsafe Port

If charterers order the ship to a prospectively unsafe port, the order is not a contractual employment order that the master must obey. The master is under the charterers’ orders as regards employment only within the charterparty limits. An order to an unsafe port exceeds those limits. The master and owners may therefore refuse the order, and if charterers persist the dispute may develop into a serious breach or even a repudiatory situation depending on the circumstances.

The master is not required to react instantly. If there is genuine doubt about safety, the master and owners may take a reasonable time to consider the order, seek information, review local conditions, and decide whether compliance is safe. Reasonable delay for safety evaluation is different from wrongful refusal to obey a legitimate order.

In many situations, however, owners and the master are entitled to rely on the charterers’ nomination as a contractual representation that the port is safe. They do not usually have a positive duty to investigate every nominated port before proceeding. That entitlement is not unlimited. If the danger is obvious, or if the owners know that the port is unsafe, they may have to refuse the order or take reasonable steps to mitigate loss.

Waiver, Election, and Damages

Owners may lose the right to refuse an unsafe port order if, with knowledge of the facts giving rise to that right, they unequivocally elect to treat the order as valid. Conduct such as serving notice of readiness, demanding priority berthing, pressing for laytime, or otherwise acting as if the port nomination is accepted may amount to an election in an appropriate case.

Waiving the right to reject the nomination does not automatically waive the right to claim damages. If owners comply with an unsafe port order and the ship is damaged by the danger against which the safe port promise protected them, owners may still recover damages unless they have also agreed, varied the charter, or are estopped from claiming that the nomination was a breach. A waiver of rejection and a waiver of damages are different legal matters.

Clear words or conduct are required before owners are treated as abandoning a damages claim. Merely proceeding under protest, arranging crew bonuses, seeking practical safeguards, or cooperating to reduce risk will not normally amount to a promise that charterers will face no liability if the ship is later damaged.

Master’s Negligence and Causation

Unsafe port disputes often involve arguments about causation. Charterers may say that even if the port was unsafe, the real cause of the damage was negligent navigation, poor seamanship, pilot error, failure to leave in time, bad mooring practice, excessive draft, defective passage planning, or failure to use available information. Owners may respond that the master was placed in a difficult situation by the unsafe nomination and acted reasonably in the circumstances.

If the master’s negligence is the effective cause of the casualty, charterers may escape liability. The chain of causation from the unsafe nomination may be broken by a sufficiently serious intervening fault. But the standard is not perfection. A master is often required to make decisions under pressure, relying on local pilots, port officials, charterers’ agents, weather information, and operational realities. If the master acts reasonably, even if the decision later proves wrong, the unsafe port may remain the effective cause of the loss.

Pilot negligence is treated with similar care. A pilot may be regarded as part of the ship’s navigational responsibility, but pilotage arrangements can also be part of the port’s safety system. If the port relies on pilotage to make the port safe, a defective or unreliable pilotage system may itself support an unsafe port claim. A single negligent act by a competent pilot within an otherwise proper system is different from a system that is structurally inadequate.

Contributory Fault and Apportionment

English law is cautious about apportioning damages in ordinary contractual safe port claims based on an absolute warranty. Where the claim is simply for breach of the charterers’ safe port undertaking, the usual analysis is causation rather than percentage division. Either the breach caused the loss, the master’s negligence broke the chain, or different parts of the loss are separated according to their causes.

There may be unusual situations where tort concepts or contributory negligence principles become relevant, especially if one party assumed a separate responsibility to provide safety information or advice and the other party reasonably relied on it. Such cases require careful analysis because the existence of the charter contract does not automatically create a separate tort duty. In many safe port disputes, the contractual allocation remains the governing framework.

Implied Safe Port Terms

If a charterparty contains no express safe port promise, a court or tribunal may sometimes imply one, but only where implication is necessary to make the charter work commercially. The more freedom charterers have to choose ports, the stronger the argument that a safety obligation is necessary. The more specifically the port is identified in the charter itself, the weaker the argument becomes, because owners may be taken to have accepted that port or satisfied themselves about its suitability.

Where the charter names a port and contains no express safe port warranty, owners may have difficulty implying one. If owners agree in advance to a specific port without obtaining safety wording, the risk may remain with owners unless another clause changes the position. If, however, the charter gives charterers broad power to nominate ports during the employment, a safety implication may be more commercially natural.

Named Ports and Safe Port Wording

A named port does not necessarily exclude a safe port undertaking. If the charter says, for example, that the ship is to trade to a named port but also contains clear safe port language, the charterers may still have warranted the safety of that named port. There is no automatic inconsistency between naming the port and promising that it will be safe.

The result depends on construction. If the words are “one safe port” followed by the name of the port, the natural reading may be that the named port is also warranted safe. If the charter identifies a port while deleting or omitting safety language, or if owners expressly acknowledge that they have satisfied themselves about the port, the opposite conclusion may follow. The degree of charterers’ liberty to choose the place is often decisive.

Breaking Trading Limits and Extra Insurance Under a Time Charterparty

Parties sometimes agree that charterers may order the ship outside the normal trading limits if charterers pay any additional insurance premium required by underwriters. Such wording gives charterers a liberty to use a wider geographical range; it does not automatically give charterers liberty to order the ship to unsafe ports. Paying extra premium is not the same as assuming ownership of all risk or eliminating the safe port undertaking.

The effect of war risk premium clauses, insurance clauses, and trading-limit-breaking clauses depends on the full wording. Some clauses may operate as a complete code for specified risks and may displace other remedies. Many do not. A charterer who pays extra premium may gain permission to trade outside ordinary limits, but still remain liable if the nominated port is unsafe and the charter has not clearly transferred that risk to owners or insurers.

Limitation of Liability Under a Time Charterparty

Time charterers may in general fall within the category of persons entitled to limit liability under maritime limitation conventions. However, where the claim is for damage to the chartered ship herself caused by breach of a safe port obligation, limitation is not normally available. The right to limit does not extend to every type of claim merely because the defendant is a charterer.

Safe Berth Obligations

A safe port obligation will usually include responsibility for the safety of berths, docks, wharves, anchorages, and other places within the port to which the ship is directed. In many charters, safe berth wording is also expressed separately. The practical test is similar to the safe port test: the particular ship must be able to enter, lie at, use, and depart from the berth without exposure to danger that ordinary good seamanship cannot avoid.

Unsafe berth issues often involve insufficient depth, defective fenders, missing mooring buoys, exposed berths, poor holding ground, inadequate dolphins, hidden underwater objects, submerged concrete, sharp steel projections, inadequate tugs, unreliable pilotage, or lack of sea room. A berth may also be unsafe if the ship can safely remain there only while weather is calm but no adequate system exists to move the ship before conditions become dangerous.

Where the charter contains a safe berth promise but no safe port promise, the safe berth obligation may not extend to risks affecting the whole port or the approach to the port. If every berth in the port is unsafe in the same way and to the same extent, and owners have accepted the port without a safe port undertaking, the safe berth wording may not shift the whole port risk to charterers. The distinction between port safety and berth safety can therefore be decisive.

Directions by Agents, Port Authorities, and Third Parties

Charterers may be liable for unsafe berth or place directions given by persons acting on their behalf. If charterers or their agents nominate a berth, bunker place, anchorage, lightening place, or loading point, the nomination may be treated as the charterers’ order. Where the nominated place is unsafe, the charterers may face liability under the safe berth obligation or under an implied indemnity for the consequences of employment orders.

The analysis becomes more difficult when the immediate direction comes from a port authority, harbour master, terminal, bunker supplier, or local operator. Such persons are not automatically charterers’ agents. Sometimes they perform independent port functions. In other cases, charterers’ order may effectively be to proceed to whatever berth or place that third party selects. The legal result depends on the commercial arrangement, the wording of the charter, and whether the third party’s instruction can properly be treated as part of the charterers’ employment order.

Safely Lie Always Afloat (AA)

The phrase “safely lie always afloat” is common in charterparty forms. In some contexts, it may focus mainly on the marine characteristics of the berth, such as depth, bottom conditions, and the ship’s ability to remain afloat. In time charter forms such as NYPE and Baltime, however, the broader safe port and safe berth wording should not be reduced to a narrow depth-only concept unless the contract clearly requires that result.

Some forms permit safe grounding where it is customary for similar ships to lie safely aground. In those cases, the obligation is not simply that the ship remain afloat at all times. The issue is whether the nominated place is contractually permitted and safe for the ship in the way contemplated by the charter.

Employment Orders and Implied Indemnity

Even where an unsafe port claim fails, owners may have a separate claim under the employment and indemnity principle. Under a time charter, the master is commonly placed under the charterers’ orders as regards employment. The law may imply an obligation that charterers indemnify owners against losses caused by complying with those employment orders, unless the loss arises from a risk that owners agreed to bear.

This alternative route is especially important where the safe port obligation is limited, absent, or reduced to due diligence wording. If the ship is damaged because she complied with charterers’ orders, and the damage was not caused by owners’ negligence or by a risk allocated to owners, the indemnity may provide a remedy even when the strict safe port analysis is unavailable.

The indemnity is not automatic. Owners must show that compliance with the order was the effective cause of the loss. If causation fails, or if the casualty was caused by an abnormal extraneous event, negligent navigation, or a risk contractually accepted by owners, the indemnity claim may fail as well.

U.S. Law on Safe Port (SP) and Safe Berth (SB) Under a Time Charterparty

U.S. maritime law generally treats safe port and safe berth wording as a substantial contractual undertaking by charterers. The commercial logic is straightforward: charterers usually control the choice of loading and discharging places, and owners surrender that commercial choice in return for charterers assuming the risk that the chosen place is safe for the ship.

American authorities have often expressed the safe berth warranty strongly. The nominated port or berth must be safe for the particular ship, and the warranty can cover not only the berth itself but also the approaches and departure route that the ship must use. Hidden obstructions, insufficient water, unsafe river passages, inadequate navigational aids, ice, defective berths, exposed moorings, and unsafe access channels may all create liability.

There has been some division in U.S. authority over whether safe berth language imposes an absolute warranty or only a due diligence obligation. The broader and more traditional approach treats the undertaking as a warranty unless the contract modifies it. A contrary Fifth Circuit approach treated safe berth wording as requiring due diligence rather than strict warranty. Later authority from another federal circuit rejected that narrower view and aligned more closely with the traditional warranty analysis.

U.S. decisions also emphasise that the port must be safe for the particular ship and that the warranty may include the waters through which the ship must pass to enter or leave. River systems such as the Mississippi, Amazon, or St. Lawrence may therefore fall within the safe port analysis when they are the necessary route to or from the nominated port.

U.S. Treatment of Master’s Conduct

Under U.S. law, as under English law, the master’s conduct remains important. The safe port or berth warranty does not excuse bad navigation, careless ship handling, failure to check available information, disregard of obvious dangers, or unreasonable refusal to follow legitimate orders. If the casualty was caused by the master’s intervening negligence rather than by an unsafe condition of the port or berth, owners may fail to recover.

At the same time, the master is not held to an impossible standard. A perfect berthing or departure is not required. If the berth is unsafe and the master’s response is reasonable in the circumstances, charterers may remain liable. If both sides are at fault, American cases may apportion responsibility according to comparative fault principles.

Acceptance of an Unsafe Place Under U.S. Law

U.S. cases also recognise that owners or the master may waive or lose reliance on the safe port or safe berth undertaking by accepting a place with full knowledge of the unsafe conditions. If the master knows the port is unsafe, enters without protest, and proceeds as though the nomination is acceptable, charterers may be relieved from liability that might otherwise arise.

The same principle is relevant where the port is named in the charter. If owners agree at the outset to a specific port, especially without an express safety warranty, they may be taken to have accepted the ordinary known conditions of that port. However, where the charter contains clear safe port or safe berth wording, naming the port does not automatically eliminate the warranty. The wording and commercial context remain decisive.

Practical Drafting and Operational Lessons

Safe port and safe berth disputes often turn on precise drafting and careful operational records. Parties should identify whether the obligation is an absolute warranty or a due diligence obligation, whether the warranty applies to named ports, whether safe berth language is intended to cover approaches, whether war risk clauses modify safety obligations, and whether payment of additional premium changes liability or merely permits wider trading.

Owners should preserve evidence of safety concerns, master’s decisions, local warnings, port information, pilot advice, weather forecasts, tug availability, berth conditions, and any protest made against the nomination. Charterers should preserve evidence of enquiries made before nomination, communications with agents, port safety information, local practices, draft restrictions, and any basis for believing that the port or berth was safe.

Operationally, the master should not treat the safe port warranty as permission to ignore obvious danger. Equally, charterers should not assume that because a port is commonly used it is safe for every ship in every season and every loading condition. The safe port obligation is ship-specific, time-specific, and fact-sensitive.

Conclusion

Safe port and safe berth obligations define one of the most important boundaries of charterers’ employment power under a time charterparty. Charterers may decide the commercial use of the ship, but that right is limited by the requirement that the ship be sent only to places that are safe for her to reach, use, and leave. The test is practical, not theoretical; it depends on the particular ship, the timing of the order, the port’s physical and political characteristics, the systems in place, and whether the relevant dangers can be avoided by ordinary good navigation and seamanship.

Where the nominated place is unsafe, owners may refuse the order, comply under protest, claim damages, or in some circumstances rely on an implied indemnity. Where owners knowingly accept an unsafe order, their right to refuse may be lost, but their right to damages will usually survive unless clearly abandoned. The law therefore balances the charterers’ freedom to employ the ship with the owners’ fundamental protection against being required to expose the ship to risks they did not agree to bear.
