Downstream energy insurance is the sub-class of energy insurance covering refineries, petrochemical plants, gas processing facilities, LNG terminals, oil storage and pipelines, providing property, business interruption and liability cover for the post-extraction segments of the oil and gas value chain.
Category: Energy insurance Also known as: downstream oil and gas insurance, refining and petrochemical insurance First codified: Lloyd’s wordings from c.1960s; modern PHF (Property Hazard Form) refinery wordings Related legislation: Control of Major Accident Hazards Regulations 2015 (COMAH) [1]; Environmental Permitting (England and Wales) Regulations 2016 [2]; Health and Safety at Work etc. Act 1974 [3]
Downstream energy insurance covers the assets and operations of the oil and gas downstream sector: oil refineries (converting crude oil into petrol, diesel, jet fuel and intermediate petrochemical feedstocks), petrochemical complexes (producing plastics, fertilisers and chemical intermediates), gas processing plants (separating natural gas into pipeline-quality methane, ethane, propane and other components), LNG liquefaction and regasification terminals, oil storage facilities and pipeline networks transporting crude oil, refined products and natural gas [4][5].
The principal exposures are: physical damage to the highly complex process plant from fire, explosion, mechanical breakdown, weather and other physical perils; business interruption losses from lost production while plant is repaired (which for major refineries can run to tens of millions of dollars per day); third-party liability for personal injury and property damage caused by major incidents; and environmental impairment liability for gradual pollution from operations or for sudden and accidental pollution from major spills [4][5].
The market is concentrated in a relatively small number of specialist energy syndicates and insurers. Capacity is dominated by Lloyd’s of London, the company markets in London and Bermuda, and a small number of specialist US energy markets. Major downstream losses (the 2005 BP Texas City refinery explosion; the 2019 Pemex Tula refinery fire; the multiple Saudi Aramco Abqaiq facility incidents) have driven significant market changes and capacity restrictions [4][5].
Major downstream facilities in the UK are classified as ‘upper-tier’ COMAH (Control of Major Accident Hazards) sites under the Control of Major Accident Hazards Regulations 2015, implementing the EU Seveso III Directive 2012/18/EU (with post-Brexit retained law continuity). The HSE and the Environment Agency are joint Competent Authorities for COMAH, requiring operators to prepare safety reports, on-site emergency plans and (in conjunction with local authorities) off-site emergency plans [1][6].
Environmental permitting under the Environmental Permitting (England and Wales) Regulations 2016 (and equivalent regimes in Scotland and Northern Ireland) sets the regulatory framework for emissions to air, discharges to water and management of waste. The Environment Agency and SEPA enforce permit conditions and may take enforcement action including civil sanctions, prosecution and revocation of permits [2][7].
The Pipelines Safety Regulations 1996 (as amended) govern the design, construction and operation of high-risk pipelines, with the HSE as the principal regulator. Major incident investigation under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR) applies across the sector [3][6].
Liability for environmental damage is governed by the Environmental Damage (Prevention and Remediation) Regulations 2015 (implementing the EU Environmental Liability Directive 2004/35/EC) and by common law principles of nuisance and negligence. Strict liability under the Rylands v Fletcher rule may apply to escape of dangerous substances from industrial facilities [2][6].
A major refinery or petrochemical complex is typically insured under a property programme covering all assets and business interruption at the site. Total insured values for major refineries can range from US$2bn to US$8bn (the property element) plus US$1bn–US$3bn of business interruption cover. The programme is normally a complex tower of primary and excess layers led by a Lloyd’s energy syndicate, with substantial capacity provided by Bermuda and continental European markets [4][5].
Underwriters require detailed disclosure of plant configuration, process safety management systems, claims experience, asset integrity management and a long list of operational risk indicators (turnaround intervals, hot work permit systems, contractor management, weather exposure). The market is highly responsive to large losses and a single major incident can drive sector-wide capacity restrictions and rate increases for several renewal cycles [4][5].
Claims handling for major downstream losses involves loss adjusters with specific refining or petrochemical engineering expertise, working alongside the operator’s project and engineering teams. A major refinery fire can result in losses of US$1bn–US$3bn comprising physical damage, business interruption (typically the largest single component), demolition costs, rebuild and decontamination. Claims regularly run for many years with reserves moving significantly as the rebuild scope is finalised and the business interruption analysis is completed [4][5].
Refinery insurance is the largest sub-class within downstream, with distinct underwriting characteristics for different refinery configurations (simple hydroskimming refineries vs complex cracking refineries with high conversion capacity).
Petrochemical insurance covers ethylene crackers, polymer plants, fertiliser facilities and the wider downstream chemical sector. The exposure profile differs from refineries (higher concentration of process units, larger inventory of intermediate feedstocks, different fire and explosion dynamics).
LNG insurance is a distinct sub-class covering liquefaction trains, storage tanks, regasification facilities and LNG carriers. The cryogenic nature of LNG operations and the very high values of major LNG projects (US$10bn or more for greenfield projects) require specialist wording and capacity.
Oil and gas pipeline insurance covers transmission pipelines and gathering systems, both onshore and offshore. The wording typically covers physical damage, business interruption and (separately) pollution liability arising from pipeline ruptures.
Oil storage insurance covers tank farms, terminals and underground caverns used for crude oil and product storage. The 2005 Buncefield (UK) and the various Houston Ship Channel tank farm fires have shaped market wording and pricing.
A UK refinery operator runs a complex hydrocracking refinery on the south coast with throughput of approximately 200,000 barrels per day and total insured property values of approximately US$5.4bn. The downstream property programme provides US$2.5bn per occurrence on a PHF-form wording with US$1.8bn of business interruption cover (calculated on a 24-month indemnity period at expected gross margins). The programme is led by a Lloyd’s energy syndicate with following markets in Bermuda and continental Europe. Annual property programme premium is approximately US$28m. The associated liability programme provides US$500m per occurrence with dedicated environmental impairment liability of US$100m above. Figures in this example are illustrative.
