What Is Offshore Energy Insurance?
Offshore energy insurance is the general name for insurance solutions addressing the construction, installation and operational risks of energy assets built and operated at sea — offshore wind farms, subsea energy cables and offshore oil and gas facilities. It is not a single standard policy; construction all risks, operational property damage, control of well, liability and loss-of-income covers are combined according to the type of asset and the phase of its life cycle.
The insurance structure that applies to onshore facilities should not be treated as automatically equivalent for offshore: the marine environment, installation vessels, weather windows, access constraints and the boundaries with marine policies change the underwriting structure. For onshore wind see Wind Energy Insurance, and for onshore oil and gas facilities see Oil & Gas Insurance. This page is general information; it does not imply the capacity of any particular insurer, acceptance of cover, price or any commitment to pay.

| Main risk focus | Typical policy components | Boundary note | |
|---|---|---|---|
| Offshore wind | Foundation and turbine installation, marine corrosion, access and weather window for repair | Offshore construction all risks (CAR/EAR), operational OAR/PD, MB, BI, DSU/ALOP, liability | Installation vessels generally sit in marine policies; fixed structure and turbines are assessed in the energy/construction policy (depends on the wording) |
| Subsea energy cables | Vessel anchors, fishing, ground movement, installation damage, fatigue at connection points | Cable installation and operation cover, BI; coordination with marine policies | Relationship between the cable owner and vessel liability for anchor and collision damage |
| Offshore oil and gas | Fire/explosion of platform and production unit, well control, subsea equipment | Offshore property (OAR/PD), Control of Well and Operator's Extra Expense, energy liability, BI | Whether floating units such as FPSOs sit in a marine or an energy policy depends on the wording |
Offshore Wind Farms
Even where the same turbine technology is used, offshore wind projects have a different risk structure from onshore wind.
- Foundation installation: Driving or placing foundations such as monopiles or jackets, seabed conditions and installation vessel operations; installation activities may be required to be approved by an independent marine warranty surveyor (MWS); the requirement depends on the policy and the contracts.
- Turbine erection: Jack-up vessel, lifting operations and weather window; waiting times and delay cost.
- Marine environment: Corrosion in a saline environment, coating damage, fatigue and structural integrity; repair times lengthened by difficult access.
- Loss of income: The need for a vessel and a weather window for repair can lead to a longer BI waiting period and indemnity period than onshore wind; DSU/ALOP is contingent on a construction loss.
- Liability: Interaction with maritime activities (vessel collision, navigation); coordination with marine liability is needed.
- Transit and project cargo: Carriage of turbine components by sea is assessed separately under the marine cargo and project cargo structure.
For turbine components and serial loss topics see Wind Energy Insurance; the component information on that page is a starting point for offshore as well, but it is not sufficient.
Subsea Energy Cables
Export cables connecting offshore wind farms to shore, and interconnections between countries, can be one of the critical points of failure of a project; cable damage is treated as a significant loss item in offshore projects (this page gives no frequency or amount figures).
- Vessel anchors and fishing activity: Among the common causes of seabed cable damage; burial depth and protection measures are queried.
- Ground movement: Scouring, slides or earthquake.
- Installation damage: Damage to the cable during laying, burial and termination.
- Fatigue: At the platform or turbine foundation entry and in dynamic cable sections.
- Repair: A specialist vessel, equipment and spare cable are needed; lead time determines the loss of income.
- Loss of income: For cable damage that shuts down all production, the indemnity period should be set accordingly.
For cable damage, the cable owner's policy and the liability of the vessel that caused the damage (P&I and H&M) may be linked; recourse rights and coordination should be verified from the policies. See P&I Insurance.
Offshore Oil and Gas Facilities
Offshore oil and gas assets include fixed and floating platforms, floating production units such as FPSOs, subsea production systems and connected pipelines. For onshore exploration and production and for refinery, LNG and pipeline activities see Oil & Gas Insurance.
- Platform and production unit: Fire, explosion and structural damage; offshore property (OAR/PD) and business interruption (BI) covers.
- Control of Well: The costs of bringing an uncontrolled well under control, redrilling and making the well safe; generally structured together with Operator's Extra Expense (OEE). Cover is not automatically available for every drilling activity; well information and the drilling programme are assessed.
- Pollution and environment: Seepage and clean-up costs and environmental liability; the boundary between energy liability and environmental policies depends on the policy. See Environmental Impairment Liability.
- Energy liability: The operator's liability arising from third-party, partner and contractor relationships; contracts often contain knock-for-knock structures.
- Subsea equipment: Damage to control lines, flowlines and manifolds.
- Construction and installation: Offshore construction-phase risks require a separate construction cover.
- Loss of income: Production interruption; dependence on wells and platform determines the BI period.
Boundary Between Marine Policies and the Energy Policy
In offshore projects, assets may combine the characteristics of a vessel and a fixed structure. If it is not clearly determined which asset sits in which policy, gaps or double insurance can arise.
Scroll the table horizontally to see all columns.
| Generally a marine policy | Generally the energy policy | Point to note | |
|---|---|---|---|
| Installation and support vessels | The vessel owner's Hull & Machinery and P&I policies; Hull & Machinery Insurance | The project's construction cover generally does not cover the vessel's own damage; whether an installation vessel is specifically included or separately arranged depends on the policy wording | Charter agreements and reciprocal liability terms |
| Fixed structures, turbines and foundations | Outside the scope of vessel policies | Offshore construction and operational policy | Which policy is on risk at the moment of installation |
| Floating units such as FPSOs | H&M and P&I may arise depending on vessel status | Production equipment and operation may sit in the energy policy | Depends on wording; gap and double insurance risk |
| Vessel collision and cable damage | P&I and H&M liability of the colliding vessel | The offshore policy of the structure or cable owner | Recourse rights and limits |
| Well control and pollution | Vessel-sourced pollution may be under P&I | Well control and OEE in the energy policy | Policy split depends on the source of pollution |
Market and Capacity Note
Offshore energy risks are mostly assessed in specialist international insurance and reinsurance markets, and capacity varies by project, location and technology. This page does not imply any capacity, limit or acceptance; Neolife carries out assessment and placement work and acceptance rests with the relevant insurer. For reinsurance structure see Reinsurance Brokerage.
Framework and Insurance in Türkiye
In Türkiye, oil and gas exploration and production are conducted within the framework of the Turkish Petroleum Law and electricity generation within the EPDK licensing framework; for activities in maritime jurisdiction areas the permit and licence conditions of the relevant authorities apply. The insurance obligations provided for onshore petroleum and LPG market licences (Law No. 5015, Article 15, Law No. 5307, Article 13 and the Communiqué on Insurance Obligations in the Petroleum Market) are not deemed to apply automatically to activities in maritime jurisdiction areas; applicability should be determined separately by licence or permit type and the nature of the activity. The investment guarantee and the damage-compensation guarantee under Turkish Petroleum Law No. 6491 are administrative/financial guarantees, not insurance policies. Insurance requirements arising from financing agreements should be verified separately.
