An introduction to Hull Claims:  Types, Process and Disputes

The shipping industry, which connects global trade, relies heavily on the importance of structural integrity in maritime operations. When ships suffer damage, hull claims come into play, impacting various stakeholders such as insurers, brokers, shipping lines, shipowners, and logistics contractors. 

Hull insurance is designed to protect against losses caused by damage to the vessel’s structure (hull), machinery, and associated equipment, including the coverage offered by hull insurance policies.

In this post, we will explore the key aspects of hull claims, including types of claims, the notification and settlement process, common disputes, and best practices.

What are hull claims?

Hull claims arise when a ship experiences damage, either due to operational incidents or external factors, and the shipowner or operator seeks compensation under the hull and machinery insurance policy. 

These claims are typically associated with the vessel’s structural damage, damage to machinery, or any equipment crucial to the vessel’s operation. This can include environmental damage, particularly if the vessel’s structural failure leads to a spill or hazardous materials release.

According to the International Union of Marine Insurance (IUMI), in 2023, hull claims accounted for approximately 40% of all marine claims

Moreover, the frequency and cost of hull claims have been on an upward trend, reflecting not only the risks associated with maritime operations but also the importance of proactive maintenance and thorough damage assessments

According to the International Union of Marine Insurance (IUMI), in 2024, in the latest Statistics Autumn 2024, From 2016 to 2023, the average cost of hull claims has shown an upward trend, driven by inflation, increased repair costs, and the complexity of modern machinery. This suggests that the financial impact of hull claims is becoming more significant, especially with rising material and labor costs. 

In addition, While there was a long-term downward trend in hull claims frequency before 2020, the report indicates a post-pandemic increase in claims. However, the levels remain moderate, and total loss frequency has only seen a slight rise. This highlights the resilience of the hull insurance market despite global disruptions

1.1. What are the common causes of hull claims?

Ships face various mechanical and environmental stresses that can compromise their structural integrity. Based on IUMI reports, the most common causes of hull claims include:

  • Collisions with other vessels or fixed objects like docks or port installations, often resulting in significant structural damage.
  • Fires on board, especially in container ships and RoRo (roll-on/roll-off) vessels, which have become an increasing concern.
  • Machinery failure, particularly in propulsion systems, with the growing complexity of onboard machinery contributing to higher claim frequency.
  • Severe weather damage from storms or high seas, which can affect the vessel’s hull and technical equipment.
  • Groundings, where vessels run aground, causing significant damage to the hull and sometimes the machinery, especially if salvage operations are delayed.

1.2. What types of vessels are most commonly involved in hull claims? 

The type of vessel, along with factors such as fleet aging, operational complexity, and the nature of the cargo transported, significantly influences the frequency of claims.

Ships are exposed to a wide range of mechanical and environmental stresses that can weaken their structural integrity.

According to reports from the IUMI and other authoritative sources in the maritime sector, the frequency of claims varies depending on the type of vessel. The types of maritime vessels that typically have a higher frequency of claims include:

  • Container ships
  • Roll-on/Roll-off ships
  • General cargo vessels
  • Tankers
  • Bulk carriers
  • Specialist vessels
  • Passenger ships

1.3. What are the types of damage in hull claims?

Hull claims can arise from various types of damage that affect the structure and functionality of a vessel.   

Below are some key types of damage commonly encountered in hull claims:

  • Collision damage
  • Grounding damage
  • Corrosion
  • Stress concentrations
  • Fatigue cracking
  • Fire and explosion damage
  • Impact from heavy seas (pounding)
  • Cargo handling damage

2.1. Types of hull claims

2.1. Total Loss Claims

Total loss claims represent some of the most significant and complex claims in marine insurance, arising when a vessel or cargo is completely destroyed, rendered irrecoverable, or so damaged that repair is either impossible or uneconomical.

Marine insurance typically distinguishes between two types of total loss: Actual Total Loss (ATL) and Constructive Total Loss (CTL), both governed by international maritime law and standard insurance policies.

  • ATL occurs when the insured property, such as a ship or cargo, is entirely destroyed or lost. This can happen in several ways, including the vessel sinking, being irretrievably lost at sea, or when the property is so severely damaged that it no longer exists in its insured form. ATL is recognized when the insured subject matter no longer exists or has been completely taken beyond the reach of its owners. Claims for ATL are straightforward, as the insurer is obligated to pay the full insured value of the lost property. In these cases, the insured must prove that the loss is absolute and irrecoverable.
  • CTL is declared when the cost of recovering or repairing the damaged vessel or cargo exceeds a certain percentage of its insured value, or the vessel is so damaged that it is no longer reasonable to attempt repair. CTL is often more complex than ATL, as it requires a thorough evaluation of whether the cost of recovery or repair makes economic sense. Under the Marine Insurance Act 1906 and internationally recognized marine insurance clauses such as the Institute Time Clauses (Hulls), CTL occurs when the shipowner, acting reasonably, abandons the vessel or cargo because the repair costs exceed the policy’s threshold, typically 75% or more of the insured value.

In both ATL and CTL cases, the policyholder can claim the full insured value of the vessel or cargo. However, for CTL, the insured must formally abandon the ship or cargo to the insurer, allowing the insurer to take possession of any salvageable material.

This process is known as notice of abandonment, and it is a legal prerequisite for recovering the full insured value under CTL provisions. The abandonment must be given promptly, and the insurer must accept or reject the notice based on an assessment of the loss.

Regulatory framework

Total loss claims are governed by various international conventions and national laws. The Marine Insurance Act 1906 continues to be the cornerstone of marine insurance law in many jurisdictions, establishing clear definitions and principles for ATL and CTL. For instance, under Section 60 of the Act, a CTL is defined based on whether it is reasonable to abandon the ship or goods due to the cost of repair or recovery.

Moreover, SOLAS compliance is a key factor in determining whether a vessel’s condition contributed to a total loss, particularly in cases where a vessel sinks or is otherwise lost.

Managing total loss claims 

Handling total loss claims requires a strategic approach, especially in CTL cases, where the decision to abandon must be made based on a comprehensive cost-benefit analysis. Engaging technical experts early in the process ensures that a realistic assessment of the damage and repair costs is conducted. Legal counsel is often necessary to manage the intricacies of abandonment notices, insurer negotiations, and compliance with international regulations.

Total loss claims are also subject to time limitations. According to the York-Antwerp Rules, which govern General Average and other maritime claims, there are strict time limits for filing a total loss claim, typically ranging from one to two years, depending on the jurisdiction. It is critical for shipowners and insurers to act quickly in filing claims to avoid the risk of being time-barred.

Additionally, total loss claims often involve salvage rights, particularly in cases where some of the vessel’s or cargo’s materials can be recovered. In such scenarios, salvage companies may be called upon to retrieve valuable assets, with salvage awards determined based on the value of the recovered property. If a CTL is declared and the insurer takes possession of the salvageable remains, they may choose to sell or auction the property, recovering part of the loss. Any proceeds from the salvage operation are typically deducted from the total indemnity paid to the insured.

2.2. Partial Loss Claims

Partial loss claims refer to damages sustained by a vessel or cargo that can be repaired or restored without declaring the vessel a total loss. These claims are common in the shipping industry and typically cover a wide range of incidents where the damage is limited to specific areas of the vessel or cargo, and repair is both feasible and economically reasonable.

Examples of partial loss claims include:

  • Hull fractures resulting from minor collisions or heavy weather damage, where the structural integrity of the vessel can be restored.
  • Machinery breakdown, such as engine or propulsion system failure, where individual components may need to be repaired or replaced.
  • Localized damage following a collision or grounding that affects a particular part of the ship, such as a damaged bow or stern section, without compromising the vessel’s overall seaworthiness.

In most cases, insurers will cover the cost of repairs to restore the vessel or cargo to its original state, subject to the terms of the policy.

The management of partial loss claims requires prompt action, with surveyors often appointed to assess the damage and recommend the most appropriate course of repair. Insurers will generally seek detailed documentation, including repair estimates and invoices, to ensure that the claim accurately reflects the costs incurred.

Unlike total loss claims, which may involve significant delays due to abandonment and salvage operations, partial loss claims tend to be resolved more quickly, allowing shipowners to return their vessels to operational status with minimal disruption. However, insurers may impose deductibles or other limitations based on the extent of the damage and the specific terms of the policy, meaning that not all repair costs may be fully reimbursed.

2.3. Sue and Labour (S&L)

The sue and labour clause is a standard provision found in most marine insurance policies. Its purpose is to obligate shipowners and cargo interests to take reasonable steps to prevent or minimize further damage to insured property after a loss. This provision is in the best interest of the insurer, as it helps mitigate additional losses, and the costs associated with these efforts are recoverable from the insurer.

The principle of sue and labour is governed by various international conventions and established maritime practices.

Under the Marine Insurance Act 1906, the insured party has a duty to “sue and labour” to protect the subject matter of the insurance. This entails taking reasonable and necessary measures to safeguard the vessel or cargo, such as hiring salvage services, conducting repairs, or securing the property.

The insurer, in turn, is obligated to indemnify the insured for such reasonable expenses, even if the efforts prove unsuccessful, provided they were made in good faith to avoid further loss.

The Institute Time Clauses (Hulls), widely used in marine hull insurance policies, explicitly include provisions for sue and labour. These clauses ensure that the insured is entitled to recover the reasonable costs incurred in efforts to avert or minimize a loss, separate from the insured loss itself.

Unlike a general average claim, which distributes liability across all parties involved, the sue and labour clause applies specifically to actions taken to protect the insured property, with costs solely covered by the insurer.

In practice, sue and labour expenses can cover a broad range of activities. For instance, if a vessel sustains damage during a voyage, the master may immediately engage salvage teams, arrange temporary repairs, or tow the vessel to safety. These expenses are typically recoverable under the sue and labour clause, treated as a distinct claim, separate from the general claim for loss or damage. This ensures that proactive efforts by the insured are incentivized and compensated.

Management of S&L claims

Proper management of S&L claims requires early coordination between shipowners, legal representatives, and insurers. Engaging technical survey experts to assess the situation is crucial in determining the scope of necessary measures and ensuring the steps taken are both reasonable and justified under the policy.

One key distinction of the sue and labour clause is that it applies regardless of the ultimate outcome of the main claim. Even if the insured property is subsequently deemed a total loss, S&L expenses incurred in the attempt to mitigate damage can still be recovered.

It is important to note that failure to take reasonable sue and labour actions can result in a denial of claims.

International regulations such as the York-Antwerp Rules and the Hague-Visby Rules reinforce the duty of the insured to act prudently and mitigate losses. If the insured neglects to take action when it is within their power to do so, insurers may reject the claim for the avoidable portion of the loss.

2.4. Salvage and General Average in Hull Claims

Salvage and General Average are key components in the framework of hull claims by determining how financial responsibilities are shared between shipowners, cargo interests, and insurers. These principles often result in disputes, particularly regarding cost distribution, compensation, and the justification of actions taken during emergencies. In salvage claims, the salvage company may be called upon to refloat a grounded vessel, fight fires, or tow a damaged ship to safety. The focus here is on saving the vessel’s hull and preventing further structural damage. Disputes often arise over the compensation due for these services, especially when the salvage efforts involve significant hull damage. For instance, salvors might argue for higher compensation when the hull is severely compromised, while insurers may question whether the efforts were reasonable or necessary. One example of a hull dispute is the Castor” incident in 2000, where a tanker experienced structural issues during a storm, leading to concerns over a potential break-up. Salvors were called to secure the vessel and tow it to safety, but disputes arose over the compensation for their efforts in preventing catastrophic hull failure. The case highlighted how disagreements over salvage operations involving the hull’s integrity can lead to hull claims disputes. General Average is similarly relevant in hull claims. When a ship’s hull is damaged or in danger, and extraordinary expenses are incurred to save it, General Average may be declared. For example, if a vessel encounters severe structural stress and the shipowner opts for emergency repairs to prevent further hull damage, the costs may be shared between the shipowner and insurers. Unlike cargo, the focus here is on the hull’s preservation, and the costs are distributed according to the York-Antwerp Rules. Disputes in hull-related General Average claims often center on the necessity of repairs or the extent of hull damage, with insurers and shipowners disagreeing over whether certain actions qualify under General Average. In such cases, the role of average adjusters is crucial, as they assess the value of the hull-related repairs and allocate the costs fairly among the parties involved. The Ever Given incident is now one of the most prominent recent cases in maritime law and hull claims, particularly concerning General Average and the complexities of grounding incidents in a critical maritime chokepoint like the Suez Canal.

2.5. Collision Claims in Hull Insurance

Ship collisions represent significant events in maritime operations, often triggering complex hull claims that involve legal, operational, and financial considerations. These claims involve the repair or replacement of the vessel’s hull and machinery, operational losses, and potential environmental damages. When dealing with collision claims in hull insurance, it is important to highlight the following five aspects:
  1. In most collisions, liability is shared between vessels, with each party responsible for hull repair costs based on their degree of fault. This principle ensures that the financial burden is equitably distributed.
  2. Prompt engagement of marine surveyors and adjusters is crucial for assessing hull damage and providing accurate repair estimates.
  3. Besides damage to the insured vessel, collisions often involve third-party claims, such as damage to other ships, cargo, or port infrastructure.
  4. Severe hull damage can lead to pollution, such as oil spills, which extend the scope of hull claims to include environmental liabilities. This is particularly relevant in tanker collisions, where pollution-related damages are significant.
  5. Insurers expect shipowners to take reasonable measures to mitigate further damage following a collision.
Claims and Recourse Actions Once liability is determined, shipowners typically file hull claims with their H&M insurers to recover the costs of repairs. These claims encompass not only the direct hull damage but also associated losses, such as machinery repairs and operational interruptions. In shared-liability cases, recourse actions are often pursued to recover costs from the other vessel’s insurers. For example, in tanker collisions, the International Convention on Civil Liability for Oil Pollution Damage (CLC 1969) may come into play if an oil spill occurs, making the polluter liable for environmental damages. The responsible party may then seek recourse from other involved parties if they share part of the responsibility. Additionally, it’s important to distinguish between a collision (involving two moving vessels) and an allision (where a moving vessel strikes a stationary object, such as a dock or bridge). While the principles of liability and hull claims are similar, the nature of the incident influences how responsibility and compensation are assigned.

3. Hull claims notification process

The notification of a hull claim is the foundational step in the claims process and is essential to ensuring timely resolution. Shipowners and operators must promptly inform their insurers following any incident to prevent delays or disputes over liability.

Steps in the hull claims notification process:

  1. Immediate notification to the insurer
    The first step is for the shipowner or operator to notify their Hull & Machinery (H&M) insurer as soon as the damage or loss occurs. This is usually required within 24 to 72 hours after the incident, as most policies have a prompt reporting clause. The notification is typically sent via email or through the insurer’s designated claims platform, depending on the terms outlined in the insurance contract.

  2. Preliminary incident report
    The initial notification should include a preliminary incident report that briefly describes the circumstances of the damage, such as the nature of the incident (e.g., collision, grounding, machinery failure), location, time, and potential extent of the damage. It’s also essential to provide details of any immediate actions taken to mitigate further damage.

  3. Marine surveyor appointment
    After the notification is received, the insurer will appoint a marine surveyor to inspect the vessel and assess the extent of the damage. In many cases, the shipowner or operator is responsible for ensuring that the vessel is available for inspection and that all necessary documents, including logs and maintenance records, are made accessible.

  4. Submission of supporting documentation
    The insured party must prepare and submit additional supporting documentation, which typically includes the ship’s logbook, maintenance records, photographs of the damage, repair estimates, and relevant contracts or agreements. Prompt submission of these documents can expedite the claims process.

  5. Insurer review and claim filing
    After receiving the surveyor’s report and supporting documentation, the insurer will review the findings to determine the validity and scope of the claim. Once this is complete, a formal claim must be filed within the timeline stipulated in the policy, often ranging from 6 months to a year after the incident.

  6. Mitigation of further damage
    Throughout the process, the insured must continue to take reasonable measures to mitigate further damage to the vessel, as required by the policy’s sue and labour clause. Insurers often reimburse reasonable costs incurred during these mitigation efforts.

4. Common disputes in hull claims

Disputes in hull claims often arise due to differing interpretations of the extent of damage, delays in processing, or underinsurance. Here’s a closer look at these key issues:

  • Extent of the damage: One of the most frequent disputes is whether damage is purely cosmetic or if it affects the vessel’s structural integrity. For example, small fractures in the hull may seem minor at first but could evolve into more severe issues. Insurers might challenge the shipowner’s assessment of the damage to reduce their liability, leading to lengthy debates over repair costs.

  • Causation of damage: Determining the exact cause of damage can be contentious, especially if multiple factors were involved (e.g., human error, adverse weather conditions, or machinery failure). Insurers may challenge the shipowner’s claim by asserting that the damage was caused by factors not covered by the policy, such as negligence or failure to comply with safety protocols.

  • Coverage disputes: Hull insurance policies contain exclusions, and disputes may occur if the insurer believes the claim falls under one of these policy exclusions. For instance, the insurer might argue that the damage was due to normal wear and tear, design defects, or improper maintenance, which are typically not covered by hull insurance.

  • Delays in claims processing: Delays often stem from incomplete documentation, disagreements over the cause of damage, or the involvement of multiple insurers. These delays can prolong a vessel’s downtime, increasing operational costs for shipowners. It’s critical to submit comprehensive evidence and collaborate with all stakeholders to expedite the claims process.

  • Repairs and costs: Shipowners and insurers frequently disagree on the cost of repairs. Shipowners may submit higher repair estimates than the insurer is willing to approve, or disputes may arise over the choice of repair yard, the necessity of certain repairs, or the use of specific materials. Insurers may also challenge the time taken for repairs, which affects loss-of-hire claims.

  • Underinsurance: A vessel insured for less than its market or replacement value can cause disputes if the insurer refuses to cover the full extent of the damages. This leaves shipowners with significant out-of-pocket expenses. Regularly updating the insured value of the vessel to match its current market value can mitigate these disputes.

  •  
  • Contributory negligence: In cases where the shipowner’s negligence contributed to the damage, insurers may argue that this contributory negligence reduces or invalidates the claim. For example, failure to maintain the vessel properly or neglecting to follow safety protocols can lead to disputes over the percentage of responsibility each party should bear.

  • Third-party liability: If the damage involves third parties, such as in collisions with other vessels or port infrastructure, disputes can arise over third-party liability. Insurers may seek to reduce their payment obligations by shifting responsibility to the other party, leading to protracted negotiations or litigation.

  • Interpretation of policy terms: A significant source of disputes is the interpretation of policy terms and clauses. Differences in the reading of key terms, such as “constructive total loss” or “actual total loss,” can result in disagreements about whether the claim qualifies for a full payout or only partial compensation.

Conclusion

Hull claims are a complex part of marine insurance, involving various stakeholders, including shipowners, insurers, and brokers. Success in handling these claims depends on a solid understanding of the types of claims, the notification process, and how disputes are resolved. Timely notifications, thorough documentation, and clear communication between all parties are essential for smooth claims management.

By ensuring that hull and machinery insurance is comprehensive and up-to-date, shipowners can minimize disputes and reduce the downtime of their vessels following an incident.
