Aging Assets, New Risk: Managing the Next Decade of Risk for Asia Pacific’s Mature Offshore Assets

A Different Risk Profile for Ageing Assets

When discussions turn to offshore energy risk, attention often focuses on new developments, emerging technologies and large capital projects. Yet one of the most significant risk challenges facing Asia Pacific's offshore sector involves assets that have been producing safely and reliably for decades.

Across the Gulf of Thailand, Malaysia, Indonesia, Vietnam, the Philippines and Australia, many offshore facilities are operating beyond the service life originally envisaged during their development. These assets continue to play an important role in regional energy supply, but as infrastructure ages, the nature of risk changes.

Ageing assets do not automatically mean higher risk. Many mature facilities continue to perform strongly thanks to disciplined operations, effective maintenance and robust asset integrity programmes. However, operators increasingly need to manage issues such as equipment life extension, corrosion, component obsolescence, workforce changes and growing maintenance requirements.

The challenge is rarely a single issue. Instead, organisations must understand how multiple risks interact across an asset's lifecycle and ensure deterioration does not translate into operational disruption. As a result, many operators are shifting their focus from maximising production to strengthening long-term resilience.

Asset Integrity Is Now a Business Decision

Asset integrity has traditionally been viewed as an engineering and maintenance responsibility. Today, it is increasingly a business issue.

A failure involving a critical offshore asset can extend far beyond repair costs. Production interruptions, contractual obligations, regulatory requirements and stakeholder expectations can all increase the financial impact of an incident. For many mature facilities, the cost of downtime may be greater than the cost of the physical damage itself.

This is particularly relevant where repairs require specialist expertise, lengthy engineering reviews or replacement parts that are difficult to source. Understanding how quickly operations can recover from an incident has become as important as understanding what might fail in the first place.

For operators, this means asset integrity should be considered alongside broader business objectives, including production continuity, capital allocation and risk financing decisions.

Why Insurance Strategies Need to Evolve

The way operators think about insurance is also changing.

Many offshore insurance programmes were originally designed around traditional replacement cost assumptions. For mature assets, however, those assumptions may no longer reflect future operational or commercial realities.

If a major platform were lost today, would an operator necessarily rebuild the same asset? In many cases, the answer may be no. Field economics, changing production profiles and advances in technology may support alternative development approaches, such as subsea tie-backs or smaller, lower-cost facilities.

As a result, operators are increasingly reviewing whether insurance valuations and programme structures remain aligned with the future role of an asset. However, these decisions are rarely straightforward. Organisations must balance valuation approaches with considerations such as partial-loss repairs, business interruption exposures and removal-of-wreck obligations.

Achieving the right outcome requires a combination of engineering, operational and insurance expertise.

Managing Risk Across the Full Asset Lifecycle

Successfully managing mature offshore assets requires more than insurance alone. It requires a clear understanding of asset condition, remaining economic life, potential loss scenarios and how those risks will be viewed by insurers.

A multidisciplinary approach can help organisations build this perspective.

Aon's engineering specialists support clients through inspections, risk assessments and business interruption studies. At the same time, valuation specialists help organisations assess whether traditional replacement cost methodologies remain appropriate or whether alternative approaches may better reflect the future purpose of an asset.

Drawing on experience across offshore oil and gas portfolios worldwide, Aon helps clients assess key considerations including partial-loss exposures, business interruption risks and fit-for-purpose replacement scenarios. These insights can then be translated into insurance programmes that are better aligned to operational realities and can be clearly supported in discussions with insurers.

Looking Ahead: Extending Asset Life with Confidence

As offshore fields mature across Asia Pacific, the conversation is shifting from asset age to asset value. Operators face increasingly complex decisions about where to invest, how long assets should remain in service, what risks are acceptable and how those risks should be financed.

Organisations that bring together engineering, operational, financial and insurance perspectives will be better positioned to make informed decisions about the future of their assets. In practice, this means extending asset life safely, improving resilience and ensuring capital is deployed where it can create the greatest value.
