A complex insurance dispute tied to damaged marine infrastructure is unfolding in federal court, raising difficult questions about liability, policy limits, and who pays when essential utility systems are harmed. At the center of the case is an Undersea Power Cable, struck during marine construction work in Washington state, and an insurer’s effort to avoid covering what could become a $20 million loss.
The legal clash has drawn attention from utility operators, insurers, and contractors nationwide because it highlights the growing risks associated with underwater infrastructure and the insurance policies meant to protect against costly accidents.

A Construction Project Turns Costly
The controversy began during a marine installation project in Puget Sound near Anderson Island. A private contractor was hired to carry out work involving the placement of marine equipment in coastal waters. During the operation, construction gear came into contact with a submerged electrical transmission line owned by a regional electric cooperative.
The damaged line was not an ordinary cable. It served as a high-voltage backup power connection designed to maintain service during outages affecting the primary system. When the cable was compromised, customers in nearby areas experienced service disruptions, forcing the utility to activate contingency measures to stabilize the grid.
Initial inspections revealed extensive harm to the submerged line. Engineers later determined that repairing the damage would be impractical, leaving full replacement as the most realistic option. The estimated cost quickly climbed into the tens of millions of dollars.
Utility Claims Focus on Negligence
The electric cooperative responsible for the line filed a lawsuit against the marine contractor, alleging negligence during the project. According to the complaint, the contractor failed to properly assess the presence of underwater infrastructure before beginning work and did not follow established safety practices meant to prevent precisely this type of incident.
The utility maintains that the location of the cable was documented and marked, and that reasonable precautions would have avoided contact. It argues that the contractor’s actions directly led to the destruction of a vital asset and placed customers at risk of prolonged power instability.
Damages sought in the case reflect not only the physical cost of replacing the cable but also related expenses tied to emergency response, system reliability, and long-term operational impacts.
Insurer Pushes Back on Responsibility
While the contractor turned to its commercial insurer for defense and coverage, the insurer took a different approach. Rather than accepting responsibility outright, the company initiated a separate legal action asking the court to clarify its obligations under the policy.
The insurer contends that the damage falls outside the scope of coverage. Its argument rests on policy exclusions that limit protection for certain types of property damage, particularly harm resulting from specific operational activities and damage to underground or submerged facilities.
According to the insurer, the loss stemmed directly from the contractor’s core work activities, placing it within excluded categories. As a result, the insurer asserts it should not be required to pay for defense costs, settlements, or any judgment that might emerge from the utility’s lawsuit.
At present, the insurer is participating in the contractor’s legal defense under a conditional arrangement that preserves its right to withdraw if the court agrees with its interpretation of the policy.
Why the Case Reaches Beyond Washington
Though rooted in a local incident, the implications of this dispute extend well beyond Washington state. Across the United States, underwater power lines, communication cables, and pipelines form the backbone of modern infrastructure, especially in coastal and island communities.
Marine contractors frequently operate in close proximity to these systems, often relying on insurance coverage to manage the financial risks of accidental damage. A ruling that narrows coverage in cases like this could reshape how contractors approach projects, from pre-construction surveys to contract negotiations and pricing.
Utilities are also watching closely. Many depend on contractors to work safely around critical assets, but they also rely on insurance mechanisms to ensure that funds are available when accidents occur. If insurers succeed in limiting coverage, utilities may face longer disputes and delayed recovery after infrastructure failures.
The Role of Policy Language
At the heart of the case lies a familiar but contentious issue: how insurance policies are written and interpreted. Commercial liability policies often contain detailed exclusions that are not always fully understood until a claim arises.
In this dispute, the insurer emphasizes language related to damage caused by operational errors and work performed on or near underground property. The contractor and the utility, on the other hand, argue that the policy was intended to cover accidental damage arising from routine work activities, especially when no intentional misconduct occurred.
Courts are frequently tasked with weighing these competing interpretations. Outcomes often depend on subtle wording differences and the specific facts surrounding how the damage occurred.
Growing Scrutiny of Infrastructure Insurance
The lawsuit arrives amid broader scrutiny of insurance practices related to infrastructure projects. Regulators and lawmakers in several states have pushed for stronger oversight of claims handling and clearer disclosure of policy limitations.
In Washington, recent legislative efforts have focused on enhancing consumer and policyholder protections, including measures that would expand regulatory authority in disputes over coverage and restitution. While these initiatives are separate from the current lawsuit, they reflect a shifting landscape in which insurers face increasing pressure to justify claim denials.
For businesses involved in large-scale construction and utilities management, these changes underscore the importance of understanding insurance coverage before projects begin.
What Happens Next in Court
The federal court overseeing the case is expected to consider motions addressing whether the insurer has a duty to defend and indemnify the contractor. Judges may review policy language, project documentation, and technical evidence related to how the cable was damaged.
A ruling in favor of the insurer would leave the contractor exposed to potentially massive liability, while a decision requiring coverage could reinforce broader interpretations of commercial liability policies in infrastructure cases.
Either outcome could influence future disputes involving marine construction and submerged assets.
Lessons for Contractors and Utilities
Beyond the courtroom, the case serves as a cautionary example for companies working near underwater infrastructure. Comprehensive site assessments, clear communication between utilities and contractors, and detailed contract terms are critical steps in managing risk.
Equally important is a thorough review of insurance policies to ensure they align with the realities of the work being performed. As infrastructure projects grow more complex and costly, the margin for misunderstanding coverage continues to shrink.
A High-Stakes Test for Liability and Coverage
As legal proceedings continue, the damaged cable remains a symbol of the financial and operational stakes tied to modern infrastructure. Whether responsibility ultimately falls on the contractor, the insurer, or a combination of parties, the decision will likely resonate across the construction and insurance industries.
The outcome may help define how risks are shared when essential systems beneath the water’s surface are accidentally destroyed—and who bears the price when prevention fails.
