Energy insurance is the specialty class covering oil, gas, power and renewable energy assets and operations, comprising upstream (exploration and production), midstream (transportation and storage), downstream (refining and petrochemicals), power generation and increasingly renewables, with cover for property, business interruption, liability, control of well and operators’ extra expense.
Category: Energy insurance Also known as: oil and gas insurance, power and energy insurance First codified: Lloyd’s energy wordings from c.1960s; modern WELCAR construction wording; OEE forms from 1970s Related legislation: Petroleum Act 1998 [1]; Oil and Pipelines Agency Act 1985 [2]; Energy Act 2008 [3]; Marine Insurance Act 1906 [4]
Energy insurance is the specialty class covering the oil, gas, power and energy sectors. It is one of the largest and most technically demanding lines in the global commercial insurance market, with capacity concentrated in Lloyd’s of London, the company markets in London, Bermuda and continental Europe, and a handful of specialist US energy markets. The class divides into several sub-classes [5][6]:
Upstream energy: exploration, drilling and production operations both offshore and onshore, including platforms, drilling rigs, subsea infrastructure, control of well and operators’ extra expense covers.
Downstream energy: refineries, petrochemical plants, gas processing, LNG terminals, oil storage and pipelines. Largely property and business interruption cover with associated liability.
Power generation: thermal (gas, coal, biomass), nuclear (separately treated under the nuclear insurance regime), hydropower and increasingly renewables including wind and solar.
Liability across the sector: oil and gas liability, oil pollution and marine pollution, and emerging hydrogen project and carbon capture covers.
The class is highly cyclical and event-driven. Major losses such as Piper Alpha (1988), Deepwater Horizon (2010), the Gulf of Mexico hurricane seasons of the mid-2000s and the more recent Russian-related war risk exposures of 2022 onwards have driven significant capacity and rating changes. The market is also exposed to long-tail pollution and environmental impairment claims arising from decades-old operations [5][6].
The UK upstream regulatory framework is set by the Petroleum Act 1998, which vests ownership of UK petroleum in the Crown and provides for the licensing regime administered by the North Sea Transition Authority (NSTA, formerly the Oil and Gas Authority). Licences impose detailed obligations on operators including (among many other matters) requirements to maintain financial security for decommissioning costs and (in some cases) for control of well risks [1][7].
The Offshore Installations (Safety Case) Regulations 2015 (as amended) implement the EU Offshore Safety Directive 2013/30/EU in UK law (with post-Brexit retained law continuity) and require operators of offshore installations to demonstrate to the Health and Safety Executive that risks have been reduced to ALARP (As Low As Reasonably Practicable). The HSE’s Offshore Division is the principal regulator for safety on offshore installations [8].
Pollution liability for offshore oil spills is governed by the Merchant Shipping (Oil Pollution Preparedness, Response and Co-operation Convention) Regulations 1998 and supporting instruments, together with the Convention on Civil Liability for Bunker Oil Pollution Damage (Bunkers Convention) 2001 as implemented in UK law. The Offshore Pollution Liability Association (OPOL), a voluntary agreement of UK Continental Shelf operators, provides additional financial security through a mutual indemnity scheme [9].
Marine Insurance Act 1906 applies to those parts of the energy programme that are marine in character — offshore platforms (insured on marine forms), subsea infrastructure, FPSOs and FLNG units, and the marine transit elements of energy supply chains. The Insurance Act 2015 modernised the duty of disclosure and warranties for non-consumer contracts including energy placements [4][10].
A major integrated energy company places its property programme as a complex tower with primary, excess and reinsurance layers covering total values of US$10bn or more. The primary layer is typically led by a London or Bermuda energy syndicate with following markets from continental European reinsurers; excess layers are placed in Bermuda, Asia and the US. The business interruption element is often the largest component of the limit, reflecting the high revenue per day of major refineries and offshore production assets [5][6].
Underwriters require detailed disclosure of the operator’s asset register, location-by-location values, business interruption exposures, claims experience, safety management systems, and a wide range of operational risk indicators (process safety performance, regulatory enforcement record, decommissioning programme). Premium is typically a function of the values insured, the loss history and the cyclical state of the market. Major losses can drive market-wide capacity restrictions and material rate increases [5].
Claims handling involves loss adjusters specialising in energy assets, often with engineering backgrounds, working alongside the operator’s project teams and the underwriters’ technical staff. Major losses (a platform total loss, a refinery explosion, a subsea pipeline rupture) can involve claims of hundreds of millions or billions of dollars and take many years to resolve. Business interruption claims involve detailed reconstruction of the operator’s lost production and the prevailing commodity prices [5][6].
The sub-classes listed above (upstream, downstream, offshore, onshore drilling, renewables, wind, solar, hydrogen, mining) each have distinct wordings, market participants and pricing dynamics. The energy market is increasingly fragmented as the energy transition reshapes the asset base and creates new risk classes.
Project-specific covers are common in the energy sector. A major construction project (a new refinery, a major pipeline, an offshore platform installation) will be insured under a project-specific Construction All Risks (‘CAR’) and Delay in Start-Up (‘DSU’) programme arranged separately from the operator’s operational property programme. The leading construction wordings in the offshore sector are the WELCAR (Worldwide Offshore Construction All Risks) family.
Liability covers in the energy sector are typically arranged as a separate programme from property, with primary general liability of US$200m–US$500m, excess liability up to US$2bn or more, and dedicated pollution liability covers (oil pollution, environmental impairment liability) sitting alongside. The 2010 Deepwater Horizon loss prompted major restructuring of pollution liability cover in the offshore sector.
A UK-headquartered integrated oil company operates production assets in the North Sea, the Gulf of Mexico and West Africa, plus three European refineries and a global trading operation. The energy property programme is placed for a total insured value of US$28bn across assets, business interruption and contingent business interruption, in a tower of primary and excess layers led by a Lloyd’s energy syndicate. The liability programme provides US$1.5bn per occurrence with a dedicated US$500m pollution liability sub-tower. Annual premium across the energy programme is approximately US$120m, with significant year-on-year movement driven by market conditions and claims experience. Figures in this example are illustrative.
