🏗️ '''Operator's all risk (OAR)''' is a comprehensive [[Definition:Property insurance | property insurance]] policy designed to cover physical loss or damage to assets, equipment, and infrastructure operated by a business — most commonly in the energy, mining, utilities, and heavy industrial sectors. Unlike standard commercial property policies that may enumerate specific covered perils, an OAR policy operates on an "all risk" basis, meaning it covers any cause of loss except those explicitly excluded. This broad coverage structure reflects the complex and high-value nature of the assets involved: oil rigs, pipelines, power plants, refineries, and processing facilities represent enormous concentrations of insured value where a narrow named-perils approach would leave dangerous gaps.

🔧 An OAR policy typically covers the [[Definition:Insured | insured's]] owned, leased, or operated physical assets against accidental damage, including mechanical breakdown, fire, explosion, natural perils, and — depending on the policy wording — [[Definition:Business interruption insurance | business interruption]] losses tied to covered physical damage. [[Definition:Underwriter | Underwriters]] assess risk by evaluating asset condition, maintenance protocols, geographic exposures (particularly [[Definition:Catastrophe | catastrophe]] risk from windstorm, earthquake, or flood), operational safety records, and the insured's [[Definition:Risk management | risk management]] practices. [[Definition:Deductible | Deductibles]] are typically substantial to reflect the severity profile of potential losses, and [[Definition:Reinsurance | reinsurance]] participation is common given the high [[Definition:Sum insured | sums insured]]. The policy wording is heavily negotiated, with particular attention to exclusions for wear and tear, gradual deterioration, defective design, and government-ordered shutdowns, as well as the scope of business interruption and extra expense coverage.

⚡ For industries where a single incident can generate hundreds of millions of dollars in property damage and lost revenue, OAR coverage is not optional — it is a foundational risk transfer mechanism that enables project financing, satisfies regulatory requirements, and protects shareholder value. Lenders and joint venture partners routinely require evidence of an OAR policy before committing capital, making the policy a commercial prerequisite as much as an insurance product. The specialty nature of OAR business means it is typically placed in the [[Definition:Lloyd's of London | Lloyd's]] market, through [[Definition:Surplus lines insurance | surplus lines]] carriers, or via large global [[Definition:Insurance broker | brokers]] with energy and infrastructure expertise. As the energy transition introduces new asset classes — offshore wind farms, battery storage facilities, hydrogen infrastructure — OAR wordings are evolving to address novel loss scenarios that legacy forms were never designed to contemplate.
