Assessing the Impact of Tropical Cyclone Formation on Atlantic Offshore Energy and Insurance Sectors

The Atlantic offshore energy and insurance sectors are facing a paradigm shift as tropical cyclones intensify and grow more frequent. From 2020 to 2025, the compounding effects of climate change have amplified cyclone risks, with economic losses from hurricanes like Helene and Milton in 2024 alone exceeding $225–250 billion and $160–180 billion, respectivelyHurricanes, storms cost US $500 billion this year: Analysis^[5]. For investors, understanding how these sectors are adapting—or failing to adapt—offers critical insights into long-term resilience and profitability.

Energy Infrastructure: A Growing Vulnerability

Offshore wind energy, a cornerstone of decarbonization strategies, is particularly exposed. A 2024 study in Nature reveals that historical 20-year tropical cyclones are now projected to occur every ~12.7 years, with intensities rising by 9.3 ms−1Amplified threat of tropical cyclones to US offshore wind energy in a changing climate^[1]. This translates to a 37% increase in the probability of turbine yielding and a 13% rise in buckling risks, with regional hotspots like the Gulf of Mexico seeing increases of up to 51%Amplified threat of tropical cyclones to US offshore wind energy in a changing climate^[1]. Traditional energy infrastructure, including oil rigs, is similarly at risk.

The economic toll is not limited to direct damage.

For example, Hurricane Ian's insured losses alone reached $42–63 billionCyclone, Hurricane, & Tropical Storm Models – Moody’s^[2], underscoring the scale of financial exposure.

Insurance Sector: Adapting to a New Normal

The insurance industry is recalibrating its risk models to account for non-stationary climate conditions. Traditional models, which rely on historical data, are increasingly inadequate as cyclone behavior becomes more erratic. The Reask UTC framework, for instance, integrates climate physics and machine learning to simulate cyclone events under varying environmental conditions, such as sea surface temperatures and wind shearReask UTC: a machine learning modeling framework to generate climate-connected tropical cyclone event sets globally^[4]. This approach allows insurers to generate climate-connected event sets, improving risk differentiation in data-sparse regions.

Underwriting practices are also evolving. Moody's RMS North Atlantic Hurricane Models now include high-resolution coastal flood and wave hazard simulations, enabling insurers to better assess offshore platform vulnerabilitiesCyclone, Hurricane, & Tropical Storm Models – Moody’s^[2]. Meanwhile, parametric insurance solutions—triggered by real-time meteorological data rather than post-event damage assessments—are gaining traction. These products offer faster payouts, critical for offshore wind developers facing operational downtimeGallagher Re teams up with experts to tackle cyclone risk dynamics^[3].

Collaborative Strategies: Bridging Energy and Insurance

Collaboration between sectors is emerging as a key risk mitigation strategy. The Joint Natural Resources Committee (JNRC) in London, for example, has introduced clauses like JNRC 2022-37A, which shifts the burden of proof for subsea sabotage claims onto insured partiesGallagher Re teams up with experts to tackle cyclone risk dynamics^[3]. This reflects a broader trend of insurers carving out high-risk exposures (e.g., terrorism, state-sponsored attacks) into separate coverage lines.

In parallel, energy firms are adopting engineering innovations to enhance resilience. The UK's optimization of monopile foundations for offshore wind turbines—reducing steel usage by 30% while improving stability—demonstrates how design adaptations can mitigate cyclone risksCyclone, Hurricane, & Tropical Storm Models – Moody’s^[2]. Similarly, synthetic cyclone hazard datasets, such as those developed for the South China Sea, are being used to stress-test turbine reliability under future climate scenariosReask UTC: a machine learning modeling framework to generate climate-connected tropical cyclone event sets globally^[4].

Regulatory frameworks are also evolving.

Meanwhile, the National Institute of Standards and Technology (NIST) is developing methodologies to quantify cyclone-induced hazards, aiming to update building codes by 2028Hurricanes, storms cost US $500 billion this year: Analysis^[5].

Investment Implications and Future Outlook

For investors, the interplay between cyclone risks and sectoral preparedness presents both challenges and opportunities. Energy firms that prioritize resilient infrastructure—through advanced turbine designs or strategic siting—will likely outperform peers. Insurers leveraging AI-driven risk models and parametric products are better positioned to capture market share in a hardening insurance landscapeGallagher Re teams up with experts to tackle cyclone risk dynamics^[3].

However, systemic risks remain.

Similarly, the insurance sector's capacity to absorb large-scale cyclone-related claims is under pressure, with reinsurance markets tightening in response to rising lossesHurricanes, storms cost US $500 billion this year: Analysis^[5].

Conclusion

The Atlantic offshore energy and insurance sectors are at a crossroads. As tropical cyclones become more destructive, strategic risk evaluation must prioritize adaptive engineering, advanced risk modeling, and cross-sector collaboration. For investors, the key lies in identifying firms that proactively address these challenges—whether through resilient infrastructure, innovative insurance products, or regulatory foresight. The next decade will test the mettle of both industries, but those that adapt will emerge stronger in a climate-defined future.
