What is Marine Insurance- Types, Features, and Coverage

Every day, products like electronics, food, textiles, or raw materials travel thousands of miles before reaching you. A mishap along the way can mean loss for suppliers, retailers, and consumers like us. How is the loss covered? Marine insurance is the solution. It provides a financial safety net for such goods that travel by sea, air, rail, or road. This is basically a type of general insurance.

Let’s understand the marine insurance meaning in detail and understand the importance of marine cargo insurance in today’s time!

What is Marine Insurance?

Marine insurance is a contract of indemnity. It is designed to protect the financial interests of businesses and individuals against the loss or damage of ships, cargo, and other goods during transit.

Traditionally, it was associated with sea travel. However, today, marine insurance extends to multiple modes of transport. This includes sea, air, road, rail, and inland waterways. 

Marine Insurance Meaning

Marine insurance is basically a type of general insurance. It has been introduced as a protection against financial loss or damage to vessels, cargo, and property while in transit by sea, air, road, or rail.

What are the Types of Marine Insurance

Marine insurance is not a single product. It is a broad category of policies.

Here are various types of marine insurance-

1. Based on Subject Matter

Hull and Machinery (H&M) Insurance

This policy covers the vessel itself, including machinery and equipment. It is taken against physical damage that could arise from perils such as collisions, grounding, and storms.

Marine Cargo Insurance

This is the most common form of marine insurance. It protects goods being transported against loss, damage, or theft.

Marine insurance is a broad category that protects against a variety of risks involved in transporting goods. It can cover the vessel itself through hull insurance, legal liabilities, and the cargo being transported. 

Marine cargo insurance, on the other hand, is a specific type of marine insurance that focuses solely on the goods in transit, whether by sea, air, or land. This makes it a subset of the broader marine insurance policy.

Freight Insurance

This policy covers financial losses incurred by carriers when freight charges are not received due to cargo damage or loss during transit.

Liability Insurance (Protection and Indemnity – P&I)

This provides coverage for legal liabilities arising from a ship’s operation, including third-party damages, injuries, or environmental pollution.

2. Based on Policy Duration and Scope

Voyage Policy

A short-term policy covering goods for a specific single transit from origin to destination.

Time Policy

This policy insures the subject matter (like a vessel) for a fixed period, usually one year.

Floating Policy (Open Policy)

This is designed for businesses with frequent shipments. It provides automatic coverage for all shipments within a specified period, often 12 months, up to a maximum insured amount.

Annual Sales Turnover Policy (STOP)

This covers a company’s total projected sales turnover over a year.

Mixed Policy

A combination of a voyage and time policy, offering coverage for a defined period and route.

What are the Features of Marine Insurance

Marine insurance has its distinct features that differentiate it from other types of insurance:

• Contract of Indemnity: The compensation is limited to the actual financial loss incurred. This helps in preventing profit from insurance claims.
• Insurable Interest: The policyholder must have a legal financial interest in the insured property at the time of loss.
• Utmost Good Faith (Uberrimae Fidei): Both parties must disclose all material facts truthfully.
• Proximate Cause: Claims are evaluated based on the dominant cause of loss.
• Subrogation: After compensating the loss, insurers may recover the amount from a third party responsible for the damage.
• Contribution: If multiple policies cover the same risk, all insurers share the loss proportionately.

Marine Insurance: Coverage, Exclusions, and Variants

It protects cargo, vessels, and related interests against loss or damage during transit from specified perils. It does not cover predictable, preventable, or commercial risks such as delays, poor packing, or normal wear and tear. 

Covered and Non-Covered in Marine Insurance Policy: What You Should Know?

The scope of coverage varies depending on the type of policy. This if often defined by the Institute Cargo Clauses:

• Clause A: Broad “all risks” coverage
• Clause B: Intermediate coverage
• Clause C: Basic, named-perils coverage

War and strikes are typically excluded unless separately insured with an additional premium.

What Marine Insurance Covers

Loss or damage to cargo:

• Fire, explosion, stranding, grounding, sinking, capsizing
• Named-perils coverage under Clause C specifies the exact risks covered

• Collision, overturning, or derailment of land transport linked to the voyage
• Discharge at port due to distress may also be covered

Broad “all risks” coverage (Clause A):

• Theft, non-delivery, breakage, chipping, denting, water damage

Losses during loading/unloading:

• Mishandling that causes total loss, if included in the policy wording or endorsements

Natural calamities:

• Floods, lightning, earthquakes, when included under “all risks” terms

Perils like piracy or collisions:

• Coverage may fall under cargo, hull, or P&I (protection & indemnity)/liability policies, depending on the product and endorsements

What Marine Insurance Does Not Cover

Commercial and predictable risks:

• Delay, loss of market, or deterioration due to late arrival
• Ordinary leakage, normal weight/volume loss, wear and tear

Preventable risks:

• Inadequate or unsuitable packing not arranged by the insurer

Willful or fraudulent acts:

What is the Difference Between Fire Insurance and Marine Insurance

Both types of general insurance protect valuable assets. But one protects our property on land while the other safeguards goods and vessels during transit.

Let us understand the difference between fire insurance and marine insurance-

Basis	Fire Insurance	Marine Insurance
Subject Matter	Physical assets like buildings or machinery	Vessel, cargo, or freight during transit
Scope of Risk	Fire-related perils, including smoke or water damage	Transit risks such as collision, theft, sinking, and natural disasters
Insurable Interest	Must exist at purchase and at loss	Must exist at the time of loss
Tenure	Fixed period, usually one year	Varies: single voyage to annual contracts
Loss Measurement	Actual measurable loss to physical property	Financial loss based on cargo or vessel value

Calculating Marine Insurance

Marine insurance premiums are generally calculated as:

Premium = (Insured Value × Rate of Premium) + Taxes & Additional Charges

Key factors influencing premium:

• Insured Value: The cost of goods plus freight and an agreed percentage for profit.
• Rate of Premium: This is determined by the insurer based on risk factors.
• Risk Factors: They include the type of goods, transport mode, route, claim history, and policy type.

Factors to Consider When Choosing a Marine Insurance Provider

You need to be very careful while choosing a marine insurance policy. 

Here are a few things that you should keep in mind-

1. You must know whether you need cargo insurance (for goods) or hull insurance (for vessels). Many insurers provide both options.
   
2. The Claim Settlement Ratio shows the percentage of claims that have been successfully settled. Higher ratios generally suggest a more reliable and smoother claim process.
   
3. Policy Type
   • Open Policy/Open Cover: This is the continuous coverage for frequent shipments.
   • Specific Policy: This is basically suitable for a single transit.
     
4. You need to carefully review policy wording to understand what is covered and what is not. 

Conclusion

Marine insurance forms an important part of international trade. It aims to provide essential protection against the unpredictable risks of transporting goods. Marine insurance basically enables businesses to secure their assets and trade globally easily.
