As a ship's master, I have dealt with marine insurance at the sharp end: declaring general average after a main engine failure in the Indian Ocean, coordinating with P&I correspondents during a cargo damage dispute, reporting a near-miss to H&M underwriters as required under my vessel's policy conditions. Marine insurance is not abstract risk management. It is the legal and financial infrastructure that determines what happens when something goes wrong at sea, and the decisions made in the first hours after an incident can determine whether a claim is paid or rejected.
This guide covers what every party in maritime trade needs to know: shipowners, cargo owners, charterers, and anyone whose business depends on goods moving by sea.
Quick Answer: What Is Marine Insurance? Marine insurance covers the loss or damage of ships, cargo, and associated property and liability during ocean transit or at port. The three core categories are Hull and Machinery (H&M) insurance covering the physical vessel, Marine Cargo Insurance covering goods in transit, and Protection and Indemnity (P&I) insurance covering third-party liability. These are typically held by different parties: H&M by the shipowner, cargo insurance by the cargo owner or shipper, and P&I by the shipowner through a mutual P&I club.
What Is Marine Insurance?
Marine insurance is the oldest form of commercial insurance. The practice of spreading maritime risk across multiple parties dates to medieval Mediterranean trade, and Lloyd's of London formalised the market in the 17th century. The Marine Insurance Act 1906 (UK) remains the primary legal framework for marine insurance globally, codifying principles developed over centuries of case law.
The legal definition in the 1906 Act captures the scope precisely: marine insurance is a contract by which the insurer undertakes to indemnify the insured, in the manner and to the extent agreed, against marine losses. A marine loss is any loss incidental to a marine adventure. That includes the vessel itself, the cargo aboard, freight income, liability to third parties arising from the vessel's operation, and expenses incurred in averting or minimising a covered loss.
The sea is a genuinely dangerous operating environment. Storms damage cargo and crack hull plating. Groundings cause hull breaches and environmental pollution. Collisions between vessels generate liability claims on both sides. Fires aboard tankers threaten vessel, crew, cargo, and the marine environment simultaneously. Cargo that arrives damaged, short-delivered, or not at all creates claims under multiple insurance layers. The function of marine insurance is to make these losses financially manageable rather than catastrophic.
The global marine insurance market was valued at approximately $30.5 billion in 2024 and is projected to reach $57.8 billion by 2034, reflecting increasing trade volumes, rising vessel asset values, and expanding liability exposures from environmental regulation.
Party | Primary Insurance | What It Covers | Premium Payer |
Shipowner | H&M + P&I + War risk | Vessel damage, third-party liability, war | Shipowner |
Cargo owner/shipper | Marine cargo (ICC A/B/C) | Goods loss or damage in transit | Shipper/buyer (per Incoterms) |
Charterer | Charterer's liability (P&I) | Liability for vessel damage, pollution, cargo | Charterer |
Freight forwarder | Freight liability | Goods in their care and custody | Forwarder |
Port/terminal | Port liability | Damage to vessels and cargo at terminal | Terminal operator |
The Main Types of Marine Insurance
1. Hull and Machinery (H&M) Insurance
Hull and Machinery insurance covers physical damage to the vessel: the hull plating, the engines and propulsion system, all mechanical and electrical machinery onboard, and the vessel's equipment. The shipowner holds this policy. It is the maritime equivalent of property insurance for a building.
The dominant standard form is the Institute Time Clauses Hull (ITC-H 1983), which governs most international H&M placements through Lloyd's and the company market. The policy is written for a fixed period, typically 12 months, covering all voyages undertaken during that period within specified navigation limits.
Navigation limits define the geographical areas within which the vessel may trade without attracting additional premium. A vessel insured for worldwide trading faces different conditions than one restricted to North European coastal trades. If the vessel trades outside its navigation limits without prior agreement, coverage may be voided or the underwriter may charge an additional premium retrospectively.
Perils covered under a standard H&M policy include perils of the seas (storm, heavy weather, flooding), fire and explosion, violent theft by persons outside the vessel, jettison, piracy (when classified as a standard maritime peril rather than war), collision with other vessels, grounding, stranding, contact with fixed and floating objects, and breakdown of machinery.
The 3/4 collision liability clause is a critical feature that many people outside the industry do not know about. Under the ITC-H, if the insured vessel collides with another and is held partly or fully liable for the damage to the other vessel, H&M covers three-quarters of that liability. The remaining quarter falls outside H&M and is covered by the P&I club. The clause exists for historical reasons rooted in the 19th-century development of marine insurance, but its practical consequence today is that H&M and P&I coverage are complementary and cannot be treated independently.
Constructive Total Loss (CTL) is declared when the estimated repair cost exceeds the insured value of the vessel, or in some cases when the vessel is missing and presumed lost. A vessel whose hull is so badly damaged that repair exceeds its market value is a CTL even if it is physically still afloat. H&M underwriters pay the agreed insured value on CTL.
During my time at sea, I went through a formal grounding survey twice. The process involves the underwriter appointing a surveyor, often a retired naval architect, who boards the vessel and inspects every affected compartment, photographs all damage, and prepares a report that goes to the underwriter before any repair work begins. Starting repairs before the survey is complete can void the claim.
Standard H&M exclusions include: ordinary wear and tear, inherent defects, wilful misconduct by the owner, war and nuclear risk (which require separate endorsement), and losses arising from trading in breach of navigation limits without consent.
2. Marine Cargo Insurance
Marine cargo insurance covers the physical loss or damage of goods while in transit by sea, including the loading and discharge operations and, usually, the inland transport legs before and after the main sea voyage. The cargo owner, shipper, or importer holds this policy depending on the terms of sale (Incoterms).
Under CIF (Cost, Insurance, Freight) Incoterms, the seller is responsible for arranging cargo insurance to the destination port. Under FOB (Free on Board) or EXW (Ex Works) terms, the buyer arranges their own coverage. Freight forwarders sometimes hold open cargo policies that cover clients' goods while in their care.
The Institute Cargo Clauses (ICC), last revised in 2009, are the standard framework for marine cargo insurance globally. They come in three variants: A, B, and C. The selection determines the breadth of coverage and the premium level.
Policy forms for cargo insurance include:
Voyage policy: covers a single shipment from point of origin to point of destination. Written for a specific vessel, voyage, and cargo description.
Open or floating policy: covers all shipments made by an exporter or importer over a defined period under a single annual agreement. The policyholder declares each shipment as it occurs, providing details of vessel, cargo, and value. Large importers and exporters operating continuous shipment programs use open policies to avoid the administrative burden of placing individual covers.
Valued policy: the agreed value of the cargo is specified in the policy at inception. In the event of a total loss, the insurer pays the agreed value without further proof of actual market value. Most cargo policies are valued.
Unvalued policy: the insured value is not agreed in advance. In the event of a loss, the claimant must prove the actual market value of the goods at the time of loss. Less common and more administratively difficult for the claimant.
Standard cargo insurance exclusions include: delay (loss of market, loss arising from commercial delay), inherent vice (damage resulting from the cargo's own nature: fruit ripening, self-heating coal, rusty steel), improper packing by the shipper, wilful misconduct by the insured, and war and strikes risks (which must be added by endorsement).
3. Protection and Indemnity (P&I) Insurance
P&I insurance covers the third-party liabilities that H&M does not. Where H&M insures the shipowner's own property, P&I insures the shipowner's liability to others: crew, cargo interests, third-party vessels, the environment, port authorities, and anyone else who suffers loss as a result of the vessel's operation.
P&I insurance is not provided by commercial insurance companies in the conventional sense. It is provided by P&I clubs: mutual associations owned and controlled by the shipowners they insure. Each member contributes premium (called an advance call) at the start of each policy year. If claims across the club exceed the total premiums collected, the club makes a supplementary call on all members for additional funds. If the year is profitable, any surplus is returned or credited against future calls. This mutuality means every member has a direct financial interest in the club's overall claims experience.
The International Group of P&I Clubs is an association of 12 major clubs that together cover approximately 90% of the world's ocean-going tonnage. Members of the International Group pool large claims above a threshold through the Group's pooling agreement: any claim exceeding approximately $10 million is shared proportionally across all clubs in the Group. Claims above a further threshold are reinsured in the commercial market through the Group's General Excess of Loss reinsurance programme.
The major International Group clubs include the UK P&I Club, Gard, Britannia, Skuld, West of England, The Standard Club, the North of England P&I Association, the Japan P&I Club, and several others. Each club operates under its own rules rather than a standardised policy document, which means the precise scope of coverage requires careful reading of the specific club's rulebook.
P&I cover includes:
Crew liability: death, personal injury, and illness of crew members under employment contracts and applicable law. This is the largest single category of P&I claims by number and a significant one by value.
Cargo liability: the shipowner's legal liability to cargo interests for loss or damage to cargo carried under a bill of lading. Distinct from the cargo owner's own cargo insurance.
Collision liability (1/4 balance): the quarter of collision liability to another vessel that H&M does not cover under the 3/4 collision clause.
Pollution: oil spill liability under MARPOL and national legislation including the US Oil Pollution Act 1990 (OPA 90). P&I clubs issue Certificates of Financial Responsibility (COFRs) required for vessels calling at US ports.
Wreck removal: the cost of removing a sunken or stranded vessel if ordered by port or coastal state authorities.
Passenger liability: death and personal injury claims from passengers on cruise vessels and ferries.
Stowaways: costs of repatriating stowaways found aboard.
Fines and penalties: port state fines for regulatory violations, including MARPOL discharge violations.
A P&I correspondent is a local agent appointed by the club in each port worldwide. When a vessel calls at a port and a claim situation arises, the master contacts the P&I correspondent immediately. The correspondent attends the vessel, assesses the situation, appoints surveyors, and coordinates the club's response. In my operational experience, the quality and speed of response from the correspondent in the first 24 hours after an incident has a significant influence on how the eventual claim resolves.
4. Marine War Risk Insurance
Standard H&M and P&I policies exclude war risk. The reason is straightforward: war creates unlimited, unquantifiable liability that commercial underwriters cannot price or reserve against on a standard premium basis. A single naval mine field can destroy dozens of vessels; a single conflict event can generate billions in claims simultaneously.
War risk H&M and P&I are placed separately, typically through the Lloyd's war risk market and specialist war risk underwriters. The Joint War Committee (JWC), a joint committee of Lloyd's and the London company market, publishes a list of areas where additional war risk premium applies: the JWC Hull War, Strikes, Terrorism and Related Perils Listed Areas. Vessels trading to or through listed areas must notify underwriters and pay an additional premium.
As of 2025, the Red Sea and Gulf of Aden remain listed areas following the escalation of Houthi attacks on commercial shipping that began in late 2023. War risk premiums for transits through the Bab-el-Mandeb strait and the Red Sea peaked at approximately 1% of hull value per voyage transit and remained elevated, with most shipping lines choosing to reroute around the Cape of Good Hope rather than pay the premiums or accept the physical risk.
War risk covers physical damage to the vessel caused by acts of war, capture, seizure, mines, torpedoes, terrorism, and piracy when piracy is classified as a war risk act rather than a standard maritime peril. The classification of piracy as war risk versus standard peril determines which policy responds. The International Maritime Bureau recorded 116 piracy incidents globally in 2024. Most incidents in the Gulf of Guinea and the Strait of Malacca are classified as standard piracy and fall under H&M. Incidents involving armed groups acting in a politically motivated manner, as in the Red Sea, are typically classified as war risk.
Kidnap and Ransom (K&R) insurance covers the cost of ransom payments and negotiation expenses when crew are taken hostage. K&R is a specialist line, not included in standard P&I, and is placed separately through specialist underwriters. The Somali piracy peak of 2010 to 2012 drove significant demand for K&R cover; the Red Sea situation from 2024 onward has renewed that demand.
5. Freight Insurance
Freight insurance covers the shipowner's or carrier's loss of freight revenue when cargo is lost or damaged and freight is therefore not earned. Under a standard bill of lading, freight is earned on safe delivery. If cargo is lost, freight may not be payable, leaving the carrier with the operating costs of the voyage without the income.
Freight insurance is sometimes incorporated into the H&M policy, and it is often included in the insured value of cargo under cargo policies (where CIF value includes freight). It is a less prominent line than H&M, cargo, or P&I but an important component of total revenue protection for carriers.
6. Charterer's Liability Insurance
Charterers occupy a legally complex position. They operate the vessel commercially but do not own it. They may cause damage to the vessel through improper orders, bunker pollution from their fuel arrangements, or cargo liability through incorrect declarations, but they are not covered by the shipowner's P&I club (which insures the owner's interests, not the charterer's).
Charterer's liability insurance, typically placed through a P&I club that offers charterer's entry (such as Britannia, Gard, or the UK Club), covers: damage caused to the chartered vessel by the charterer's improper operation, pollution liability from the charterer's fuel and cargo, cargo liability for goods carried under charterer-issued bills of lading, and collision liability where the charterer bears responsibility.
7. Port Risk Insurance
Port risk insurance covers vessels while they are laid up in port or undergoing dry dock surveys and repairs, outside the vessel's normal trading pattern. The exposure is different from a vessel actively trading: a vessel at anchor or in dry dock faces different perils (fire from dockyard operations, collision from other vessels manoeuvring alongside, flooding during repair). Port risk is typically written on a policy basis separate from the time H&M policy but using similar Institute clauses, and the premium reflects the lower sea-related exposure.
Type | Who Holds It | Primary Cover | Policy Form | Key Exclusion |
H&M | Shipowner | Physical damage to vessel | ITC-H 1983 | War, wear and tear |
Marine cargo | Cargo owner/shipper | Goods loss or damage in transit | ICC A, B, or C | Delay, inherent vice |
P&I | Shipowner (through club) | Third-party liability | Club rules | War risk, contractual liability |
War risk | Shipowner | War, piracy (war act), terrorism | War risk clauses | Nuclear, biological |
Freight | Carrier | Loss of freight income | Incorporated into H&M or cargo | Wilful misconduct |
Charterer's liability | Charterer | Vessel damage, pollution, cargo | Club rules (charterer's entry) | War, wilful misconduct |
Port risk | Shipowner (laid-up vessel) | Vessel at anchor or in dry dock | Modified H&M clauses | Trading, war |
Institute Cargo Clauses A, B, and C Explained
The Institute Cargo Clauses are the standard terms on which most international cargo insurance is placed. They were developed by the Institute of London Underwriters (now the International Underwriting Association) and last comprehensively revised in 2009. They replace the older terminology of Free from Particular Average (FPA), With Average (WA), and All Risks (AR) that appears in older trade documentation.
The three clauses represent different breadth of coverage:
ICC (A): Broadest Cover ICC (A) is an "all risks" policy in the sense that it covers all risks of loss or damage to the cargo unless specifically excluded. The exclusions in ICC (A) include: wilful misconduct of the insured, ordinary leakage and wear and tear, inherent vice, delay, insolvency or financial default of shipowners, unseaworthiness where the insured was aware, nuclear risk, and war and strikes (unless added by endorsement). ICC (A) is the right choice for high-value or fragile cargo where almost any loss is commercially significant.
ICC (B): Named Perils, Medium Breadth ICC (B) covers a specified list of perils rather than all risks. Covered perils include: fire or explosion, vessel being stranded, grounded, sunk, or capsized, collision or contact of the vessel with any external object, discharge of cargo at a port of distress, earthquake, volcanic eruption or lightning, general average sacrifice, jettison, washing overboard, entry of sea, lake, or river water into the vessel or cargo container, and total loss of any package lost overboard during loading or discharge. ICC (B) is a middle-ground option that covers the most common and significant perils at a lower premium than ICC (A).
ICC (C): Minimum Cover ICC (C) covers only the most fundamental catastrophic perils: fire or explosion, vessel stranded, grounded, sunk, or capsized, collision, discharge at a port of distress, general average sacrifice, and jettison. ICC (C) does not cover washing overboard, water damage, or theft. It is appropriate for robust bulk cargo in sealed containers where only catastrophic total loss events are of material concern, and where the cargo owner can self-insure smaller damage events.
Feature | ICC (A) | ICC (B) | ICC (C) |
Coverage type | All risks (with named exclusions) | Named perils | Named perils (minimum) |
Fire and explosion | Yes | Yes | Yes |
Stranding, sinking, collision | Yes | Yes | Yes |
Jettison | Yes | Yes | Yes |
General average | Yes | Yes | Yes |
Washing overboard | Yes | Yes | No |
Entry of seawater | Yes | Yes | No |
Theft | Yes | No | No |
Earthquake damage | Yes | Yes | No |
Total loss of package overboard | Yes | Yes | No |
War and strikes | By endorsement | By endorsement | By endorsement |
Relative premium | Highest | Medium | Lowest |
Best for | High-value, fragile cargo | General manufactured goods | Robust bulk, low-value cargo |
General Average: The Most Misunderstood Concept in Marine Insurance
General Average is the principle that when a voluntary sacrifice or expenditure is made for the common safety of a ship and all the cargo aboard, the resulting loss is shared proportionally by all parties whose property benefited from the sacrifice. It is one of the oldest principles in maritime law, with origins in ancient Rhodian maritime custom, and it remains legally operative in virtually every maritime jurisdiction today.
The legal framework is the York-Antwerp Rules (YAR), most recently revised in 2016. Most charter parties, bills of lading, and cargo policies incorporate YAR 2016 by reference, making it the operative standard for GA adjustment worldwide.
The classic scenario: a vessel encounters severe weather. The master judges that the vessel will founder unless cargo is jettisoned to reduce weight and improve stability. Fifty containers are jettisoned. The vessel survives. The owners of the jettisoned containers have lost their cargo. The owners of the remaining 500 containers have their cargo intact and have benefited from the sacrifice. Under GA, every cargo owner on the vessel, plus the shipowner for the vessel itself, contributes proportionally to the value of property saved, to compensate those whose property was sacrificed.
The contribution ratio is called the GA contribution, calculated by a specialist GA adjuster (firms such as Richards Hogg Lindley or Stolt Nielsen). The process takes months to complete and requires valuation of every single piece of property aboard at the time of the incident.
The Ever Given grounding in the Suez Canal in March 2021 generated a GA declaration affecting every cargo owner on board the vessel, approximately 400 containers' worth of freight. GA security had to be posted by each cargo owner before their containers could be released. Cargo owners without cargo insurance had to post cash security or a bank guarantee. Cargo owners with a good cargo policy simply had their insurer post the security on their behalf.
This is why cargo insurance matters even for relatively straightforward shipments. A vessel carrying your cargo can declare GA for reasons entirely unrelated to your goods: an engine fire, a grounding in a distant port, a collision in fog. Without cargo insurance covering your GA contribution, you may not be able to recover your goods until you post substantial security.
The GA adjustment process involves:
Master declares GA and appoints a GA adjuster
GA adjuster issues GA security requests to all cargo interests
Cargo interests post security (cash, bank guarantee, or P&I letter of undertaking)
Cargo released
GA adjuster completes full calculation (typically takes 12 to 36 months)
Parties receive final GA adjustment, either paying or receiving balance
In my experience declaring GA after an engine failure that required emergency towage and diversion to a port of refuge, the most immediate practical challenge was reaching all cargo interests quickly enough to arrange security before the cargo began deteriorating. The P&I correspondent was invaluable in managing that communication.
Piracy and War Risk Coverage in 2025-2026
The International Maritime Bureau (IMB) recorded 116 piracy and armed robbery incidents against ships globally in 2024. The Gulf of Guinea (West Africa), the Strait of Malacca, and the Red Sea/Gulf of Aden were the principal hotspot areas.
For insurance purposes, the critical question in any piracy incident is classification: is it piracy under the standard H&M policy, or is it an act of war under the war risk policy? The answer determines which underwriter pays.
Standard piracy, meaning criminal opportunists boarding vessels for theft or cargo robbery, is covered under H&M as a peril of the sea. The Houthi attacks in the Red Sea from late 2023, involving anti-ship ballistic missiles, naval drones, and coordinated military-style operations against commercial vessels, were classified by the Joint War Committee as war risk. Vessels transiting the area without war risk cover faced uninsured exposure.
The practical consequence was swift: the JWC added the Red Sea, Gulf of Aden, and Bab-el-Mandeb to the Listed Areas requiring additional war risk premium. Most major shipping lines stopped Red Sea transits and rerouted around the Cape of Good Hope, adding 10 to 14 days and significant bunker costs to each Asia-Europe voyage. Those that continued transiting paid war risk premiums that reached approximately 1% of hull value per voyage transit at the peak, with cargo war risk premiums layered on top.
For crew, piracy incidents generate P&I claims for injury or psychological trauma. However, ransom payments for crew taken hostage are typically excluded from standard P&I club coverage. Shipowners with vessels operating in high-risk areas maintain separate Kidnap and Ransom (K&R) policies through specialist underwriters, covering ransom payments, negotiation costs, and crisis management services. K&R policies are confidential by standard practice; neither the existence of the policy nor the claim details are disclosed publicly.
Marine Insurance Policy Types
Beyond the coverage categories (H&M, cargo, P&I), marine policies take different structural forms:
Voyage policy: covers a single voyage from one port to another. Standard for one-off cargo shipments.
Time policy: covers all voyages undertaken during a fixed period, typically 12 months. Standard for H&M and for open cargo facilities held by large traders.
Open or floating policy: an ongoing arrangement covering all shipments under a master policy. The policyholder declares each shipment as it occurs, confirming the vessel, departure date, cargo description, and insured value. Open policies suit importers and exporters with continuous shipment programs.
Valued policy: the agreed value of the insured property is set at policy inception. On total loss, the insurer pays the agreed value without requiring proof of market value at the time of loss.
Unvalued policy: the value of the cargo is not agreed in advance. The claimant must prove market value at the time of loss. Less convenient for the claimant but sometimes used for high-value goods where the insurer requires proof of actual loss.
Port risk policy: covers a vessel while laid up in port or in dry dock, on terms that reflect the different risk profile of a vessel not actively trading.
Fleet policy: a single policy covering all vessels in an owner's fleet, typically on a combined H&M basis. Simplifies administration and may achieve economies of scale on premium.
Builder's risk policy: covers a vessel under construction at a shipyard, from keel-laying to delivery.
The Marine Insurance Claims Process
How a marine insurance claim is handled in the first hours after an incident often determines whether it is paid in full, settled at a discount, or disputed. The following sequence applies to both H&M and cargo claims, with P&I claims following a parallel process through the club correspondent.
Step 1: Immediate Notification The insured must notify the insurer or P&I club as quickly as possible after an incident, ideally within 24 hours. Late notification is grounds for the underwriter to deny some or all of the claim. For H&M claims, notification goes to the insurer's agent or Lloyd's broker. For P&I, the club correspondent at the nearest port is the first contact.
Step 2: Survey Appointment The underwriter appoints a surveyor to inspect the vessel, cargo, or site of the incident. The survey is a formal examination by a qualified inspector, often a chartered surveyor or naval architect. The survey report is the primary evidentiary document for the claim.
Step 3: Preservation of Evidence The insured has an obligation to preserve all evidence relevant to the claim: photographs and video of the damage, official logbook entries, crew statements taken while memories are fresh, original cargo documents, weather records, AIS tracking data, and any correspondence with port authorities. Failure to preserve evidence weakens the claim and may allow the insurer to argue the loss cannot be properly quantified.
Step 4: Mitigation Both H&M and cargo policies require the insured to take all reasonable steps to minimise further loss after an incident. A vessel taking in water should pump bilges. Damaged cargo should be segregated from undamaged cargo to prevent further contamination. Failure to mitigate can reduce the quantum of the claim.
Step 5: Document Submission The formal claim is submitted with supporting documents: the survey report, repair estimates (for H&M) or damage certificates and replacement costs (for cargo), invoices for emergency expenses, the vessel's official logs, and the relevant policy documents.
Step 6: Underwriter Assessment The underwriter reviews the claim, the survey report, and the supporting documents. They may appoint an independent loss adjuster for large or complex claims. The underwriter assesses the quantum (the financial value of the claim) and whether the loss falls within the policy terms.
Step 7: Settlement or Dispute Resolution Most claims are settled by negotiation between the insured (through their broker) and the underwriter. Disputed claims may go to arbitration (the standard in London market policies) or litigation.
Subrogation applies in marine insurance as in all indemnity insurance: when the insurer pays the claim, it acquires the insured's right to pursue recovery from the responsible party. If a vessel is damaged in a collision caused by another vessel, the H&M underwriter pays the claim and then pursues the negligent vessel's P&I club for recovery.

Assessment | Review and quantify | Underwriter/loss adjuster | Settlement letter |
Resolution | Settlement or arbitration | Both parties | Settlement agreement |
Marine Insurance Exclusions: What Is Not Covered
Understanding what marine insurance does not cover is as important as understanding what it does.
Inherent vice: loss or damage resulting from the cargo's own nature. Coal self-heats and can ignite during a long voyage; this is not a peril of the sea but an inherent property of the commodity. Fresh fruit ripens and spoils; this is not damage from an insured peril. Inherent vice is excluded from all three ICC sets.
Delay: losses arising from commercial delay are excluded under all standard marine cargo policies. If cargo arrives late and the market has moved, or if a time-sensitive contract is missed, the cargo insurer is not liable. Delay is a commercial risk, not an insurance risk.
Ordinary wear and tear: gradual deterioration of a vessel's hull, machinery, or equipment through normal use is not covered by H&M. The vessel is expected to be properly maintained.
Wilful misconduct: deliberate acts by the insured or the insured's senior servants that cause a loss void the policy. Scuttling a vessel for the insurance money is the extreme case, but less dramatic examples of misconduct can also void coverage.
War and nuclear risk: excluded from standard H&M and cargo policies; require separate war risk endorsements as described above.
Unseaworthiness (known): if the shipowner was aware at the time of departure that the vessel was unseaworthy (for example, that safety equipment was defective or that the vessel was overloaded), and a loss results from that unseaworthiness, the H&M and P&I cover may be void.
Improper packing: cargo damaged because it was inadequately packed by the shipper is excluded from cargo policies. The insurer covers losses from transit perils, not losses from the shipper's pre-transit handling.
ISPS and ISM failures: some H&M underwriters include conditions that coverage is conditional on the vessel maintaining valid ISM Code certification and ISPS compliance. Lapsing certification can create coverage gaps.
FAQ On Marine Insurance
What is marine insurance and why is it needed?
Marine insurance provides financial protection for ships, cargo, and associated liabilities during maritime operations. It is needed because the sea creates genuine, material risks to property and life that would be financially catastrophic without insurance. Most maritime trade and vessel ownership is economically viable only because marine insurance makes the risks manageable.
What are the main types of marine insurance?
The three primary types are Hull and Machinery (H&M) insurance covering the physical vessel, Marine Cargo Insurance covering goods in transit, and Protection and Indemnity (P&I) insurance covering third-party liability. Additional types include war risk insurance, freight insurance, charterer's liability, and port risk insurance.
What does P&I insurance cover?
P&I insurance covers the shipowner's legal liability to third parties: crew death, injury, and illness; cargo damage liability; collision liability (the 1/4 balance not covered by H&M); oil pollution liability; wreck removal; passenger liability; and fines and penalties. It is provided by mutual P&I clubs rather than commercial insurers.
What is the difference between H&M and P&I insurance?
H&M covers physical damage to the vessel itself. P&I covers the owner's legal liability to others arising from the vessel's operation. They are complementary: H&M pays for the dent in the hull; P&I pays the claims of the cargo owner whose goods were damaged in the collision that caused the dent. The 3/4 collision liability clause in H&M means the two policies always interact in collision situations.
What are Institute Cargo Clauses A, B, and C?
ICC (A) is the broadest "all risks" cargo cover, protecting against all perils except named exclusions. ICC (B) covers named perils including fire, stranding, collision, jettison, and seawater entry, but not theft. ICC (C) covers only the most fundamental perils: fire, stranding, collision, and general average. Premium levels follow breadth: ICC (A) highest, ICC (C) lowest.
What is General Average in marine insurance?
General Average is the legal principle that when a voluntary sacrifice is made to save a ship and all cargo from a common peril, the loss is shared by everyone whose property benefited. If cargo is jettisoned to save a vessel, all other cargo owners contribute to compensate the owners of the sacrificed cargo. Cargo insurance covers the insured's GA contribution automatically, which is one of the strongest practical reasons to hold cargo insurance.
Does marine insurance cover piracy?
It depends on how the piracy is classified. Standard opportunistic piracy (robbery by criminals at sea) is covered under H&M as a peril of the sea. Piracy classified as an act of war (such as the Houthi attacks in the Red Sea) falls under war risk insurance, which is separate from standard H&M. Crew ransom payments are generally not covered by P&I and require a separate Kidnap and Ransom policy.
What is war risk insurance for ships?
War risk insurance covers physical damage to vessels and cargo resulting from acts of war, mines, terrorism, and piracy classified as a war act. It is placed separately from standard H&M because the unlimited and unquantifiable nature of war liability cannot be included in standard premiums. The Joint War Committee publishes a list of areas requiring additional war risk premium.
Who pays for marine cargo insurance?
It depends on the Incoterms of the sale. Under CIF terms, the seller arranges and pays for cargo insurance to the destination port. Under FOB or EXW terms, the buyer arranges their own coverage from the point of risk transfer. In practice, most importers and exporters hold their own open cargo policies rather than relying on the counterparty's insurance.
What is a floating policy in marine insurance?
A floating or open policy is an annual arrangement covering all shipments made by a shipper or importer during the policy period, under a single master agreement. The policyholder declares each individual shipment as it occurs, providing the vessel name, sailing date, cargo description, and insured value. Open policies simplify administration for high-volume traders.
How do P&I clubs work?
P&I clubs are mutual associations owned by their shipowner members. Each member pays an advance call at the start of the year. If total claims exceed total premiums, the club makes supplementary calls on members for additional funds. If the year produces a surplus, it is returned or credited. The International Group of P&I Clubs pools large claims above approximately $10 million across all 12 major clubs, and the Group purchases General Excess of Loss reinsurance for very large claims.
What is the claims process for marine insurance?
The process runs: immediate notification to the insurer or P&I correspondent; survey appointment; preservation of evidence (photographs, logs, witness statements); mitigation of further loss; formal claim submission with supporting documents; underwriter assessment; and settlement or arbitration. Prompt notification and thorough evidence preservation are the two factors most within the insured's control that influence claim outcomes.
