Energy & Power, where physics, geology, and political risk all sign the same slip.

Energy insurance covers the assets and operations of oil and gas extraction, refining, distribution, and electric power generation. The exposures are large, the perils are unique, and the markets are concentrated in London, Bermuda, and a handful of US specialists. The line straddles property and casualty in ways most other lines do not.

§ 01

The mental model

Energy assets are large, long-lived, and concentrated. A single offshore platform can carry $1B+ of insured value. A single refinery can be worth multiples of that. A blowout, a fire, an explosion, or a major equipment failure can produce nine and ten figure losses, sometimes from a single event. The line exists to underwrite those exposures with the structural sophistication they require.

Energy insurance has its own coverages, its own forms, its own market structures, and its own loss culture. Operators Extra Expense (OEE) is unique to upstream oil and gas. WELCAR is a construction wrap unique to offshore projects. Generation interruption coverage for power plants behaves more like business interruption than like casualty BI. Each major energy asset class has its own bespoke wordings, its own underwriting team at most carriers, and its own loss adjusters who specialize in that asset type. The line does not generalize well, and that is fine: very few brokers and underwriters cover all of energy. They specialize.

Anchor concept

Energy insurance is asset-class-specific, technically demanding, and concentrated in a handful of specialty markets. Generalist underwriters do not work in energy. The markets, the wordings, and the loss culture all reward depth.

§ 02

Upstream, midstream, downstream

The standard segmentation of the oil and gas industry, mirrored in the insurance market.

Upstream
Exploration and production. Drilling rigs, wellheads, platforms, subsea equipment. Onshore and offshore. The most catastrophic loss exposures (blowouts, well control events, platform losses). Operators Extra Expense is the signature upstream coverage.
Midstream
Transportation and storage. Pipelines, gathering systems, storage tanks, LNG terminals. Long-distance assets with concentration risk at terminals. Pollution and BI are central concerns.
Downstream
Refining and chemical processing. Refineries, petrochemical plants, distribution terminals. Major property values, complex BI exposures, severe potential for explosion and fire loss.

Each segment has its own dominant carriers, its own preferred forms, and its own risk engineering practice. Some carriers cover multiple segments; many specialize.

§ 03

Operators Extra Expense (OEE)

OEE is the signature upstream oil and gas coverage. It responds to the costs of regaining control of a well that has experienced a blowout or other loss of control event. The exposure is unique to drilling and production; it does not exist anywhere else in property and casualty.

What OEE covers

  • Cost of control. The expense of regaining control of the well: well control specialists (Boots and Coots, Wild Well Control, similar), heavy equipment, materials, capping operations, relief wells.
  • Redrilling and extra expense. Cost of redrilling a lost well to the depth at which control was lost.
  • Seepage and pollution. Cost of cleaning up oil, gas, or drilling fluids released as a result of the loss event. Often a separate sub-limit.
  • Care, custody, and control. Liability for damage to the well itself.

How it differs from property

OEE is not property coverage in the traditional sense. The well is not a building; the loss is not the destruction of a structure. The loss is the cost of regaining control of an out-of-control well. Standard property forms cannot address this. OEE was developed specifically for the upstream context and remains the foundational coverage for any drilling or production operator.

The Macondo example

The 2010 Deepwater Horizon disaster (the Macondo well in the Gulf of Mexico) was the largest OEE-related loss in history. BP as operator faced multi-billion dollar costs of well control, cleanup, and consequential losses. The market hardened sharply afterward, capacities tightened, and underwriting standards for deepwater drilling rose substantially.

§ 04

Property damage and BI

Energy property coverage protects the physical assets: rigs, platforms, refineries, processing equipment, tanks, pipelines. The forms are bespoke for the asset class.

Major property forms

  • Operating offshore property. Platforms and equipment for production. Wordings derived from London market forms (e.g., LSW 1090).
  • Operating onshore property. Refineries, processing plants, terminals. Energy-specific manuscript wordings or standard property forms with energy endorsements.
  • Drilling rigs. Land rigs and offshore drilling units. Specialty hull-style coverage on London marine forms for floating units, property forms for land rigs.

Business interruption in energy

Energy BI calculations are complex. For a refinery, the BI value is the gross profit on processed product, net of variable costs. For an offshore platform, BI is the value of production deferred. Time element coverage often includes extra expense, denial of access, and contingent BI for upstream and downstream interdependencies. Indemnity periods for major energy assets can run 24-36 months reflecting how long major repair takes.

Cat exposure

Gulf of Mexico hurricane is the dominant natural cat exposure for offshore property. Wildfire and severe convective storm increasingly material for onshore. Earthquake for some pipelines and processing facilities. Cat modeling for energy combines standard cat models with bespoke assessments of the specific asset's physical resilience.

§ 05

Construction wraps and WELCAR

Energy construction projects (offshore platforms, refineries, LNG facilities, pipelines) involve massive capital investment over multi-year construction periods. Specialty wraps cover these projects.

WELCAR

WELCAR (the WELl CAR form, a London market form for offshore construction projects) is the standard wrap for offshore energy construction. It covers physical damage to the project during construction, third-party liabilities, and certain extensions like delay in start-up. WELCAR 2001 is the dominant version still in use, with various amendments and updates.

Onshore construction

Onshore energy construction uses CAR (Construction All Risks) forms, often with energy-specific endorsements. EAR (Erection All Risks) covers the installation of equipment and machinery. Both are typical components of large refining or LNG project insurance programs.

Delay in start-up (DSU) and advance loss of profits (ALOP)

Massive capital projects have massive consequences if completion is delayed. DSU and ALOP coverages respond to lost gross profit during a delay caused by covered loss to the project. The indemnity period and the projected revenue assumptions are some of the most heavily negotiated terms in energy construction wraps.

§ 06

Power generation and renewables

Electric power generation has its own corner of the energy market, with distinct exposures and forms.

Conventional power

Coal, natural gas, oil, and nuclear power plants. Property and BI coverage, with attention to gas turbine machinery breakdown, boiler and pressure vessel coverage, and contingent business interruption from grid disturbances. Nuclear has its own pool-based coverage system (Nuclear Electric Insurance Limited and others) given the unique exposure profile.

Renewable power

Wind (onshore and offshore), solar (utility-scale and distributed), hydroelectric, geothermal, biomass. Each technology has its own loss profile.

  • Onshore wind. Lightning, gearbox failure, blade damage, hail. Increasingly a frequency-driven loss profile as fleets age.
  • Offshore wind. Larger units, more challenging access, hurricane and severe weather exposure. Newer than onshore wind by a decade or more, with loss data still maturing.
  • Utility-scale solar. Hail damage to panels, fire from inverters, severe weather. Sensitive to PV technology generation and to mounting structure resilience.
  • Battery energy storage. Fire risk from lithium-ion thermal runaway. A small but rapidly growing exposure with limited loss history.

The energy transition

The shift toward renewables is one of the largest structural changes in the energy market. Insurance capacity is following the capital. Conventional fossil fuel capacity is contracting in some markets as ESG mandates push insurers away from coal in particular. Renewable capacity is growing, with new entrants and existing carriers expanding appetite. The cycle dynamics in renewables are not yet stable.

§ 07

Liability and pollution

Energy operations carry severe third-party liability and pollution exposures. Coverage is layered across CGL, excess casualty, OEE seepage and pollution, environmental impairment liability (EIL), and specialty pollution forms.

The pollution coverage problem

Standard CGL forms exclude most pollution. Energy operations need pollution coverage as core, not optional, protection. Specialty environmental forms (Pollution Legal Liability, contractor's PL with energy extensions) fill the gap. For upstream operators, OEE seepage and pollution coverage handles event-based pollution from blowouts. For midstream and downstream, broader environmental coverages address ongoing operational pollution risk.

OPA 90

The Oil Pollution Act of 1990 (OPA 90), passed after the Exxon Valdez incident, imposes strict liability on operators of vessels and facilities that discharge oil. OPA 90 caps and exceptions are intricate, and the financial responsibility requirements drive both the carrying capacity needed and the coverage structures used for tankers and offshore facilities.

Casualty exposure

Energy operations also face standard casualty exposures: contractor injuries, third-party bodily injury and property damage, products liability for processed products. Casualty layers behind the operational coverages; the casualty side is more familiar to non-energy underwriters than the property side.

§ 08

The market

Energy insurance is concentrated. A handful of major markets writes the bulk of the global business.

Major markets

  • Lloyd's of London. Significant share of upstream and downstream energy capacity. Specialist syndicates dominate.
  • Bermuda. Major energy carriers including Chubb Bermuda, Liberty Specialty Markets, Renaissance Re, and others. Significant role in excess casualty and large property layers.
  • US energy specialists. Specialty energy divisions of major US carriers (e.g., AIG, Liberty, Chubb, AXA XL). Onshore US business and US-domiciled operator programs.
  • Continental European markets. Munich Re, Swiss Re, Allianz, AXA XL all maintain energy practices, though Lloyd's and Bermuda dominate capacity.
  • Mutuals and pools. Oil Insurance Limited (OIL) is a Bermuda-based mutual owned by major energy companies that provides high-limit property capacity to its members.

Distribution

Energy placements typically run through specialist energy brokers (Aon, Marsh, WTW, Lockton, Gallagher all have large energy practices, with several specialty firms also operating in the space). The retail-wholesale-Lloyd's broker chain often shows up on energy placements, with multiple specialty brokers in the chain by class.

§ 09

Where IDP earns its keep

Energy submissions are document-heavy with engineering reports, asset schedules, BI workbooks, and bespoke wordings. The volume per submission is high; the format heterogeneity by asset class is also high.

01
Intake
Slip, schedules, surveys, BI workbook.
02
Classify
Upstream, midstream, downstream, power.
03
Extract
Asset schedules, values, OEE limits.
04
Validate
Schedule vs slip, BI inputs, gap analysis.
05
Triage
Class fit, capacity, cat exposure.
06
Underwriter
Pre-populated workspace + risk highlights.

Indico use cases

  • Asset schedule normalization. Convert operator asset registers (rigs, platforms, refineries, units of generation) into carrier-standard schedules.
  • BI workbook ingestion. Extract gross profit, throughput, indemnity period, and waiting period assumptions from operator BI workbooks.
  • Survey summarization. Convert engineering surveys into structured underwriting findings (deficiencies, recommendations, ratings).
  • Wording comparison. Track year-over-year changes in bespoke energy wordings between expiring and renewal slips.
  • Subcontractor enrollment. For wraps and OCIPs, manage the subcontractor enrollment and certificate tracking process.
Where the demo lands

For an energy underwriter, the BI workbook ingestion agent is the demo. Operator BI workbooks vary widely (each operator has their own template), and pulling the gross profit, throughput, and indemnity period assumptions into a normalized form is mechanical work that takes hours per submission. Compress to seconds with full source citation, and the underwriter has the BI inputs ready before the call with the broker.
