The study of failure is fundamentally the study of risk management ignored. It is the rigorous examination of the chasm that opens up between calculated efficiency and uncalculated fragility.
In the world of high-stakes engineering and finance, there exists a specific, insidious form of systemic failure: the deliberate creation of a catastrophic, low-probability risk that is financially underwritten not by the corporation that profits from it, but by the public that merely lives near it. This is the failure of accountability—a process where the architecture of success is paid for by institutionalizing the architecture of public disaster.
Today, we turn the Failureology lens onto an active, high-stakes case study in North America: the looming risk surrounding the Line 5 oil and gas pipeline in the Straits of Mackinac. The recent reports detailing the potential financial fallout of a catastrophic failure lay bare a profound lesson: modern infrastructure is often designed with a massive, uninsured liability attached, demonstrating a fundamental flaw in our regulatory and ethical foresight.
The ongoing debate over the Line 5 tunnel replacement project has transitioned from a localized environmental protest into a textbook lesson on the consequences of risk externalization. This is not merely a debate about oil; it is a clinical dissection of how we choose to tolerate catastrophic risk, and who is ultimately forced to underwrite the ensuing collapse.
1. The Case Study: A $4 Billion Contingency Hidden in Plain Sight
The Line 5 dual pipelines, operated by the Canadian company Enbridge, transport millions of gallons of crude oil and natural gas liquids daily beneath the Straits of Mackinac, the highly sensitive junction point between Lake Michigan and Lake Huron. The pipeline’s continued operation has been fiercely debated due to its age and the extreme environmental sensitivity of the region, which a University of Michigan researcher identified as the “worst place for a Great Lakes Oil Spill.”
The recent chilling development that elevates this situation to a must-read Failureology case study is the stark gap between the potential cost of a disaster and the company’s demonstrated ability to pay for it. A report compiled by environmental organizations brought together multiple analyses showing that a major failure could cost Michigan taxpayers up to $4 billion. Line 5 opponents warn pipeline failure could leave taxpayers on the hook for $4 billion | WCMU Public Radio.
The numbers speak for themselves:
- Worst-Case Economic Loss: Projections place the potential economic loss, including tourism and shipping channel shutdowns, at up to $45 billion.
- Enbridge’s Financial Resources: As of 2019, the parent company had the financial resources to cover approximately $1.87 billion in damages, a figure deemed “on the low end” of the potential cost.
- Insurance Coverage: The liability insurance covers only $940 million.
The difference is a massive, multi-billion-dollar deficit that, under the current legal framework, could be transferred to Michigan taxpayers. This is the ultimate lesson in Risk Management Failure: the enterprise has guaranteed itself a profit while guaranteeing the public an uninsured, existential liability.
2. The Anatomy of Risk Externalization: A Failure of Ethics and Governance
In the context of Failureology, this situation is not a natural disaster; it is a manufactured vulnerability. It represents a failure not of engineering—though the aging pipeline is a physical risk—but of the governance systems designed to protect the public from the fallout of private profit.
Risk externalization occurs when a company (or government entity) profits from an operation but legally and financially distances itself from the full cost of its worst-case scenario. This is achieved through:
The Failure of Contractual Foresight
The current agreements, designed to transfer the tunnel to state ownership, raise the specter that the Michigan taxpayers, not Enbridge, could be responsible for the catastrophic cleanup, water system repairs, tourism losses, and multibillion-dollar infrastructure disruptions. This is a profound failure of the initial contractual architecture to assign liability commensurate with the scale of the risk.
A robust system of risk governance must operate on a simple principle: the entity that creates the risk must bear its full, un-capped cost. When liability is capped below the worst-case scenario, the system is incentivized to gamble with public well-being, knowing that the cost of failure will be socialized. This is a structural failure of due diligence and accountability in the commercial safeguards that were supposed to protect the public interest, a flaw mirrored in surging contractor failures in the construction sector where a lack of financial due diligence and clear commercial oversight shifts financial risk to the developer (and ultimately, the consumer).

The Cognitive Bias of Underestimation
The failure to insure against the worst-case scenario is a classic cognitive bias: The Normalcy Bias. We assume that because catastrophe hasn’t happened yet, it won’t. This bias is reinforced by economic models that systematically underestimate the probability and impact of tail risks (extreme, rare events).
In this case, the analysis of financial resources available ($1.87 billion) versus the potential cost ($45 billion) shows a tolerance for a risk-to-equity mismatch that would be unacceptable in any other regulated industry. The system—both corporate and governmental—is acting under the collective delusion that the maximum loss will be manageable, ignoring the non-linear, compounded failure that defines a true environmental disaster.
3. The Catastrophe We Cannot Model: Compounding Systemic Failure
The true danger in the Straits of Mackinac, and in any single-point-of-failure infrastructure, is not the initial spill itself, but the cascading, compounded failure it triggers. The financial estimates hint at this complexity:
- Environmental-Economic Cascade: A spill instantly destroys tourism and fishing economies, which leads to job losses, tax base erosion, and a multi-state public health crisis. The failure is not contained to the water; it infects the local economy.
- Infrastructure Interdependency: The Line 5 pipeline is a single failure point, but its collapse could necessitate the long-term shutdown of the vital shipping channel, halting commercial traffic. This is a disruption to the wider regional and international supply chain, demonstrating how infrastructure failures can infect the macroeconomic sphere.
This concept of compounded failure is the same phenomenon that engineers warn about in other critical sectors. For instance, in delta cities like Shanghai, flood risks are increasing not because of one factor, but the combination of sea-level rise, land subsidence, and extreme climate events. Experts warn that this compounding effect could lead to a “catastrophic failure” of current flood defenses because a layered, resilient defense is missing. Flood risks in delta cities are increasing, study finds | PreventionWeb.net.
The Line 5 debacle is the energy equivalent: a system designed to withstand a single leak or a single storm, but utterly unprepared for the compounding tragedy of a major leak combined with inadequate emergency response, unpredictable weather patterns, and the paralysis of governance.
4. The Law of Brittle Systems: The Failure of Maintenance
Beyond the financial and ethical dimensions, the Line 5 pipeline symbolizes a global failure of investment in critical infrastructure resilience. Every system—be it an aging pipeline or an electric grid—is on a slow path of degradation. Resilience is not achieved by building things, but by maintaining them.
When we look globally, we see the consequences of chronic underinvestment in maintenance:
- The Cuban Power Grid: Massive power outages, like the one recently hitting Cuba’s western region, are blamed on a “crumbling electric grid” and aging infrastructure. Massive power outage hits Cuba’s western region | POLITICO Pro. These failures are not sudden events; they are the cumulative result of deferred maintenance, political instability, and a consistent prioritization of short-term cost savings over long-term stability.
The lesson is universal: The cost of maintenance is always less than the cost of collapse. The failure to maintain aging infrastructure is not an economic decision; it is a failure of stewardship—a political and corporate choice that mortgages the future for current convenience. It is the ultimate expression of the brittle system: one that is optimized for current throughput until the day its structural integrity finally fails, leading to an immediate and total service disruption.
5. The Post-Mortem of the Future: Underwriting Resilience
For Failureology, the Line 5 situation demands a post-mortem performed before the disaster. What reforms are necessary to prevent the public from underwriting private, catastrophic risk?
- Mandatory Uncapped Liability Insurance: Companies operating critical infrastructure that poses an existential risk to the public good must be required to hold insurance or escrow funds that are equal to the highest estimated worst-case scenario, with no cap. If a company cannot afford to underwrite its own potential disaster, it should not be allowed to operate.
- The Priority of Resilience Over Efficiency: Every decision regarding critical infrastructure must be judged by its capacity for safe failure, not its capacity for throughput. If an operation requires a perpetual state of financial and environmental gambling, the operation is fundamentally flawed and must be retired or replaced with a truly resilient alternative.
- Governance by Critical System Standards: Regulatory bodies must adopt global standards for resilience, such as those laid out in ISO 22372: Guidelines for Resilient Infrastructure, which provides a framework for managing complex disaster risks (like climate change, cyber threats, and structural integrity) in a coordinated way. New ISO 22372 standard sets global framework for safer infrastructure | UNDRR. The failure to adopt such rigorous, internationally-vetted standards is, itself, a failure of governance.
The debate over the Line 5 pipeline is a crucial moment for systemic learning. It is a confrontation with the true, hidden cost of efficiency and the ultimate price of unaccountable risk. We are being asked to choose between an immediate convenience for a few and the long-term, uninsured stability of an entire ecosystem for everyone.
The only acceptable conclusion is that a system designed to fail on the public dime is a system that deserves to be shut down. Resilience is not a profit center; it is a precondition for civilization.
