Marine insurance is a vital part of global trade and logistics. It provides protection against losses or damages to cargo, ships, terminals, and other transport-related goods. While most people associate insurance with health or vehicles, marine insurance is one of the oldest and most critical branches of coverage, especially in today’s interconnected global economy.

In this article, we’ll clearly explain marine insurance, its types, how it works, and why it’s essential for anyone involved in shipping or international commerce.

What Is Marine Insurance?

To explain marine insurance simply, it is a contract between an insurer and a shipowner, cargo owner, or freight forwarder to protect against financial loss from maritime risks. These risks may include natural disasters, piracy, accidents at sea, theft, or damage during transit. The policy ensures compensation is paid in case of an insurable event affecting the ship, cargo, or both.

Marine insurance can apply to:

Cargo shipped by sea, air, or land

Commercial ships and tankers

Shipping containers and onboard equipment

Marine insurance is governed by international principles and maritime law. It acts as a financial safeguard for businesses that rely on shipping goods internationally.

Types of Marine Insurance

When you explain marine insurance, it’s essential to distinguish its main categories:

Hull Insurance Covers physical damage to the ship or vessel itself. It is usually taken by shipowners.

Cargo Insurance Protects goods in transit against loss or damage. It is commonly purchased by exporters, importers, or freight agents.

Freight Insurance Covers the shipping company’s loss if the freight charge is not earned due to cargo loss or voyage failure.

Liability Insurance Also called Protection and Indemnity (P&I), this type covers legal liabilities like injury to crew or damage to third-party property.

Why Marine Insurance Matters in 2025

Global trade continues to grow, but so do its risks. The maritime sector faces ongoing threats from:

Piracy in certain sea lanes

Climate-related storms and hurricanes

Port congestion and handling errors

Geopolitical unrest affecting shipping routes

According to global trade statistics, nearly 80% of goods are transported via sea. Without marine insurance, a single loss event can wipe out millions in value for a company.

In 2023 alone, over 2,000 cargo claims were filed due to incidents involving fire, grounding, or extreme weather conditions at sea.
