14.4 Ocean Marine Coverages (Hull, Cargo, Freight, P&I)

Ocean Marine Insurance

Ocean marine is the oldest line of insurance and covers vessels, their cargoes, and the legal liabilities arising from waterborne commerce. It is largely non-standard (manuscript) and governed heavily by maritime law and custom rather than ISO forms. The exam expects you to know its four principal coverages and several distinctive marine clauses and average concepts.

Ocean marine policies are typically written on a named-perils basis and often include a war risk option (bought back after the standard FC&S exclusion). Valuation is usually on a valued (agreed) basis - the policy states the insured value of the hull or cargo and pays that amount on a total loss, avoiding disputes over fluctuating market values mid-voyage.

The four coverages of an ocean marine policy:

Distinctive ocean marine clauses

• Perils clause - lists insured perils ('perils of the sea': sinking, stranding, collision, heavy weather), plus the Inchmaree clause extending to latent defects, boiler bursts, and crew negligence.
• Running Down Clause (RDC) / Collision liability - hull coverage for the insured's liability for damaging another vessel by collision.
• Sue and Labor clause - obligates the insured to take reasonable steps to minimize loss; the insurer reimburses those expenses.
• Free of Capture and Seizure (FC&S) - excludes war risk (war is bought back separately).
• General Average vs Particular Average - the heart of marine loss sharing, below.

General Average vs Particular Average

• Particular Average = a partial loss borne solely by the owner of the lost/damaged property. (A 'With Average' (WA) policy covers partial losses; 'Free of Particular Average' (FPA) covers only total losses or losses from major perils.)
• General Average = a partial loss voluntarily and deliberately incurred for the common safety (e.g., jettisoning cargo to save the ship). The sacrifice is shared proportionally by all parties to the voyage - ship, cargo owners, and freight interest - based on their saved values.

This sharing principle is unique to marine and a frequent exam item.

Three conditions must be met for a valid general average: the peril must be real and imminent, the sacrifice must be voluntary and intentional, and the act must be successful in saving at least part of the venture. If the ship is lost anyway, there is nothing saved to contribute. Each party's marine policy then pays that party's general-average assessment, so the cargo owner whose goods were jettisoned is made whole through the pooled contributions rather than bearing the entire loss alone.

Worked example - general average contribution

During a storm a captain jettisons $200,000 of one shipper's cargo to refloat a grounded vessel - a general average sacrifice. The total saved values at the voyage's end are: ship $3,000,000, total cargo $1,500,000, freight $500,000 = $5,000,000 total interests.

The general average contribution rate = sacrifice / total saved values = $200,000 / $5,000,000 = 4%. Each interest contributes 4% of its value:

• Ship: 0.04 x $3,000,000 = $120,000
• Cargo (all owners): 0.04 x $1,500,000 = $60,000
• Freight: 0.04 x $500,000 = $20,000

Total contributions = $200,000, reimbursing the shipper whose cargo was sacrificed. Each party's marine policy pays that party's share.

The Four Ocean Marine Coverages

Ocean marine insurance, the oldest line, covers four interests. Hull insurance covers physical damage to the vessel itself. Cargo insurance covers the goods being shipped. Freight insurance covers the shipping revenue the carrier loses if cargo is not delivered. Protection and Indemnity (P&I) covers the shipowner's liability to third parties, including injury to crew and passengers, damage to other vessels and property, and pollution. Knowing which of these four interests a scenario describes is the starting point for every ocean marine question.

Distinctive Ocean Marine Clauses

Ocean marine policies use clauses unique to the line. The perils clause enumerates the marine perils (perils of the sea, fire, jettison, barratry, and others). The Free of Particular Average (FPA) clause limits coverage for partial losses, while a With Average (WA) clause covers partial losses subject to a percentage. The Inchmaree clause covers losses from latent defects, bursting of boilers, and crew negligence that the basic perils clause would not reach. The sue and labor clause requires and reimburses the insured for efforts to minimize a loss. These clauses appear regularly on the exam.

General Average vs. Particular Average

Average means partial loss in marine terminology, and the distinction between its two types is heavily tested. Particular average is a partial loss that falls entirely on the owner of the lost or damaged property. General average is a partial loss voluntarily and reasonably incurred for the common safety of the whole maritime venture, such as jettisoning some cargo to save the ship and remaining cargo in a storm; the loss is then shared proportionally by all parties whose property was saved, ship, cargo, and freight interests alike. The voluntary-sacrifice-for-common-safety element defines general average.

Worked Example: General Average Contribution

Suppose a captain jettisons 100,000 dollars of one shipper's cargo to lighten a grounded vessel and save the venture, and the total values saved are the ship at 600,000 dollars and remaining cargo at 400,000 dollars, plus the sacrificed 100,000 dollars, for a 1,100,000-dollar contributory base. Each interest contributes proportionally to reimburse the shipper who lost cargo for the common good: the ship interest bears 600,000 / 1,100,000 of the 100,000-dollar sacrifice (about 54,545 dollars) and the cargo interests bear the rest.

The exam tests recognizing a general-average situation and computing each interest's proportional contribution to the sacrificed value.
