Upstream energy insurance is the sub-class of energy insurance covering exploration and production (E&P) assets and operations, including offshore platforms, drilling rigs (onshore and offshore), subsea infrastructure, control of well exposures and operators’ extra expense cover.
Category: Energy insurance Also known as: upstream oil and gas insurance, E&P insurance, exploration and production insurance First codified: Lloyd’s wordings from c.1960s; modern OEE forms from 1970s; WELCAR construction wording Related legislation: Petroleum Act 1998 [1]; Offshore Installations (Safety Case) Regulations 2015 [2]; Marine Insurance Act 1906 [3]
Upstream energy insurance covers the physical assets and the operational exposures of the oil and gas exploration and production sector. The principal assets are fixed offshore platforms (jackets, gravity-base structures, tension-leg platforms, spars), floating production units (FPSOs, FPUs, FLNG units), mobile offshore drilling units (jack-ups, semi-submersibles, drillships), subsea infrastructure (wellheads, manifolds, flowlines, risers, umbilicals) and the supporting fleet of offshore supply vessels, anchor handlers and crew change craft [4][5].
The principal operational exposures are: damage to the assets themselves from accidents, weather, fire and other physical perils; loss of production income while the assets are repaired (business interruption or loss of production income, LOPI); the cost of regaining control of an out-of-control well (control of well); the costs of redrilling and reworking the well; pollution from blowouts and spills; and liability to third parties for personal injury, property damage and pollution [4][5].
Cover is provided through a mix of forms. The physical asset cover is normally on a marine ‘all risks’ form modified for energy use (the London Standard Drilling Barge form for drilling units; bespoke wordings for FPSOs and fixed platforms). The well control cover is on the dedicated operators’ extra expense (OEE) form. Liability cover is on energy liability wordings developed by the London market over the past four decades. Construction phase risks are insured separately under WELCAR (Worldwide Offshore Construction All Risks) or similar wordings [4][5].
The Petroleum Act 1998 vests ownership of UK petroleum in the Crown and provides for the licensing regime administered by the North Sea Transition Authority. Production licences impose extensive obligations on operators including (relevantly for insurance) requirements to maintain financial security for decommissioning costs, to comply with the operator’s environmental management plan, and to satisfy the Offshore Pollution Liability Association (‘OPOL’) membership requirements where applicable [1][6].
The Offshore Installations (Safety Case) Regulations 2015 require operators to demonstrate to the Health and Safety Executive that risks have been reduced to ALARP. The Offshore Safety Directive 2013/30/EU (as transposed into UK law) sets minimum financial responsibility requirements for offshore operations [2][7].
The Petroleum Activities (Civil Liability) Regulations 2018 implement liability provisions of the Offshore Safety Directive in UK law, including strict liability for pollution damage from offshore oil and gas activities. The OPOL agreement is the principal voluntary mechanism for UK Continental Shelf operators to meet financial responsibility requirements for pollution, providing a mutual indemnity up to US$250m per incident [8].
The Marine Insurance Act 1906 governs the marine elements of the upstream programme — fixed platforms, floating production units and offshore vessels are insured on marine forms and the MIA 1906 principles of insurable interest, fair presentation (as modified by the Insurance Act 2015), warranties and average apply [3][9].
A major upstream operator places its physical damage cover on a global or regional basis, with the policy covering specific platforms, drilling rigs and subsea infrastructure on a schedule with agreed values. Limits per occurrence are typically US$1bn–US$3bn for major operators, with separate sub-limits for specified perils (named windstorm in the Gulf of Mexico, for example) reflecting market capacity constraints. The cover is supported by business interruption or loss of production income for the operator’s working interest share of the lost production [4][5].
Well control cover (OEE) is normally placed under separate wordings and limits, reflecting the specific risk profile of well blowouts. Limits per well per event are typically US$100m–US$500m, with higher limits for high-pressure high-temperature wells, deepwater wells and exploration drilling in frontier basins. Cover responds for the costs of regaining control (specialist contractor charges, mobilisation of well control vessels, blowout preventer replacement), for redrilling and reworking the well, and for seepage and pollution costs [4][5].
Liability cover for the upstream operator is normally arranged as a separate programme from physical damage, with primary general liability of US$100m–US$500m and excess liability up to US$1bn–US$2bn for major operators. The wording covers personal injury, property damage and pollution liability arising from the operator’s activities, with the precise allocation of cover between general liability, OEE and dedicated pollution covers requiring careful coordination [4][5].
Offshore platform insurance is the largest sub-class within upstream, with distinct wordings for fixed platforms, floating production units and mobile drilling units.
Onshore drilling insurance covers land-based drilling operations, with different exposure profiles (less weather exposure, easier access for well control intervention, different pollution dynamics) and different wordings.
Operators’ extra expense (OEE) and control of well cover the operational risks of drilling and producing wells.
Construction-phase covers for new platforms, pipelines and subsea infrastructure are written on WELCAR or equivalent wordings, with delay-in-start-up extensions for the lost production income during construction delays.
Joint venture exposures are common in upstream and require careful programme design. A typical North Sea field is operated by one company on behalf of a consortium of partners, each holding a percentage ‘working interest’. Insurance arrangements may be jointly placed by the operator on behalf of all partners (with cost allocated by working interest) or may be placed separately by each partner — the choice has implications for limits, deductibles and claims handling.
A UK-listed independent E&P operator holds working interests in five North Sea producing fields (two as operator), comprising three fixed platforms and two subsea tie-back developments to neighbouring host platforms. The operator’s share of the total insured value across the portfolio is approximately US$2.4bn. Upstream physical damage cover is placed for US$1.2bn per occurrence on a marine all-risks wording with named windstorm sub-limits and a US$25m deductible. OEE cover is placed for US$250m per well per event on a separate wording with a US$10m deductible. Liability cover provides US$500m per occurrence with dedicated pollution and excess liability layers above. Annual upstream programme premium is approximately US$15m–US$22m depending on market conditions. Figures in this example are illustrative.
