The Challenge
The Shetland HVDC Project presented a particular combination of physical and operational complexity. High-voltage transmission infrastructure was being built across a difficult landscape, with multiple large contractors running their own programmes in parallel, each with their own teams, their own rhythms and their own pressure to keep work moving.
In that environment, environmental compliance does not manage itself. Scottish environmental legislation and the project's own environmental plans set clear requirements, but the distance between a requirement written in a document and a contractor team applying it correctly in the field is where problems tend to appear.
The challenge for Ocean Winds was maintaining consistent standards across all of those interfaces, not just at the level of project documentation, but at the level of what was actually happening on site every day. Environmental issues in construction programmes like this one tend to emerge at the boundary between contractors, or in the gap between a site team's immediate priorities and the environmental controls they are supposed to be following. Left unaddressed, they become regulatory findings.
The Solution
ERSG placed Environmental Coordinators, Advisors and Permitting Managers within the programme - people who worked on site, not from an office, and who were present in the places where compliance risk was most likely to materialise.
The team conducted routine inspections across active worksites, which served two purposes. The first was identifying issues before they escalated. The second was making it normal for contractors to see environmental oversight as part of the construction environment rather than an external imposition, which tends to produce better results than purely reactive enforcement.
When issues were found, the team managed escalation quickly. A clear process for identifying, reporting and resolving environmental problems meant that findings did not sit unresolved, and that project leadership had visibility of any emerging risks in time to act on them.
Compliance records were maintained continuously throughout the programme. The Environmental Coordinators tracked inspection outcomes, documented site activities and kept records to the standard required for regulatory and audit purposes, which mattered both during construction and after it.
The Permitting Managers worked across the contractor interfaces to ensure that permit-related requirements were understood and that activities remained within the conditions that had been set.
The Outcome
The project completed construction with a clean environmental record and no regulatory findings. That is the clearest measure of what the team delivered, but it was the product of consistent, unglamorous work across a long and complex programme rather than any single intervention.
Contractors maintained more consistent environmental standards than might otherwise have been the case, in part because the environmental team was present, visible and engaged rather than periodic and distant. Issues that did arise were caught early and resolved without becoming delays or escalations.
Scottish environmental legislation and the project's own environmental plans were met throughout. Ocean Winds closed out the construction phase without the kind of compliance legacy that can follow a project into its next phase.
