Marine Insurance

From Wikipedia, the free encyclopedia

Marine insurance covers the loss or damage of ships, cargo, terminals, and any transport or cargo by which property is transferred, acquired, or held between the points of origin and final destination.
Cargo insurance—discussed here—is a sub-branch of marine insurance, though Marine also includes Onshore and Offshore exposed property (container terminals, ports, oil platforms, pipelines); Hull; Marine Casualty; and Marine Liability.

Origins of formal marine insurance

Maritime insurance was the earliest well-developed kind of insurance, with origins in the Greek and Roman maritime loan. Separate marine insurance contracts were developed in Genoa and other Italian cities in the fourteenth century and spread to northern Europe. Premiums varied with intuitive estimates of the variable risk from seasons and pirates.^[1]
The modern origins of marine insurance law in English law were in the law merchant, with the establishment in England in 1601 of a specialized chamber of assurance separate from the other Courts. Lord Mansfield, Lord Chief Justice in the mid-eighteenth century, began the merging of law merchant and common law principles. The establishment of Lloyd's of London, competitor insurance companies, a developing infrastructure of specialists (such as shipbrokers, admiralty lawyers, and bankers), and the growth of the British Empire gave English law a prominence in this area which it largely maintains and forms the basis of almost all modern practice. The growth of the London insurance market led to the standardization of policies and judicial precedent further developed marine insurance law. In 1906 the Marine Insurance Act was passed which codified the previous common law; it is both an extremely thorough and concise piece of work. Although the title of the Act refers to marine insurance, the general principles have been applied to all non-life insurance.
In the 19th century, Lloyd's and the Institute of London Underwriters (a grouping of London company insurers) developed between them standardized clauses for the use of marine insurance, and these have been maintained since. These are known as the Institute Clauses because the Institute covered the cost of their publication.
Within the overall guidance of the Marine Insurance Act and the Institute Clauses parties retain a considerable freedom to contract between themselves.
Marine insurance is the oldest type of insurance. Out of it grew non-marine insurance and reinsurance. It traditionally formed the majority of business underwritten at Lloyd's. Nowadays, Marine insurance is often grouped with Aviation and Transit (i.e. cargo) risks, and in this form is known by the acronym 'MAT'.

Practice

The Marine Insurance Act includes, as a schedule, a standard policy (known as the 'SG form'), which parties were at liberty to use if they wished. Because each term in the policy had been tested through at least two centuries of judicial precedent, the policy was extremely thorough. However, it was also expressed in rather archaic terms. In 1991, the London market produced a new standard policy wording known as the MAR 91 form and using the Institute Clauses. The MAR form is simply a general statement of insurance; the Institute Clauses are used to set out the detail of the insurance cover. In practice, the policy document usually consists of the MAR form used as a cover, with the Clauses stapled to the inside. Typically each clause will be stamped, with the stamp overlapping both onto the inside cover and to other clauses; this practice is used to avoid the substitution or removal of clauses.
Because marine insurance is typically underwritten on a subscription basis, the MAR form begins: We, the Underwriters, agree to bind ourselves each for his own part and not one for another [...]. In legal terms, liability under the policy is several and not joint; i.e. the underwriters are all liable together, but only for their share or proportion of the risk. If one underwriter should default, the remainders are not liable to pick his share of the claim.
Typically, marine insurance is split between the vessels and the cargo. Insurance of the vessels is generally known as 'Hull and Machinery' (H&M). A more restricted form of cover is 'Total Loss Only' (TLO), generally used as a reinsurance, which only covers the total loss of the vessel and not any partial loss.
Cover may be on either a 'voyage' or 'time' basis. The 'voyage' basis covers transit between the ports set out in the policy; the 'time' basis covers a period of time, typically one year, and is more common.

Protection and indemnity

Main article: Protection and indemnity insurance

A marine policy typically covered only three-quarter of the insured's liabilities towards third parties. The typical liabilities arise in respect of collision with another ship, known as 'running down' (collision with a fixed object is an 'harbor'), and wreck removal (a wreck may serve to block a harbor, for example).
In the 19th century, ship-owners banded together in mutual underwriting clubs known as Protection and Indemnity Clubs (P&I), to insure the remaining one-quarter liability amongst themselves. These Clubs are still in existence today and have become the model for other specialized and noncommercial marine and non-marine mutual’s, for example in relation to oil pollution and nuclear risks.
