Sullom Voe Terminal Begins Decommissioning Phase with Key Removals

Details regarding the decommissioning process at Sullom Voe Terminal (SVT) have been unveiled, outlining significant infrastructure removals. The initial phase will involve the removal of six crude tanks and three ballast tanks. Additionally, topside infrastructure from two jetties is also slated for removal. This initiative aligns with SVT operator EnQuest’s plans to modify its processing facilities, aimed at creating a smaller infrastructure footprint reflective of “substantially” reduced production rates.

Decommissioning Strategy and Environmental Considerations

The early decommissioning details are outlined in a newly released environmental impact assessment scoping document submitted to the planning service. This strategy focuses on dismantling equipment that has reached the end of its operational life while ensuring continuous service for oil and gas operations east and west of Shetland. The document highlights that the decommissioning programme “creates potential re-use opportunities,” as foundational structures, drainage systems, and road infrastructure will remain intact for future developments.

All six crude storage tanks, which have not been in service for many years, present a “risk to people,” according to the document. These tanks contain hydrocarbons and will undergo thorough cleaning before removal. Similarly, the three ballast tanks, which have also been decommissioned, are considered a risk and are included in this initial phase. Alongside these tanks, a pipe track, cabins, and a transfer facility are also scheduled for removal.

Future Phases and New Energy Developments

The decommissioning process at SVT is structured into four distinct phases. The second phase is anticipated to commence in 2030, followed by the third phase projected for 2050. The final phase will focus on site remediation. The timing of these subsequent phases is expected to correlate with the relinquishment of the SVT lease.

Plans for new energy developments at the site are also in the works, with the potential for hydrogen production and carbon capture/storage initiatives. This transition reflects a broader shift in the energy landscape, as infrastructure is repurposed to accommodate modern energy solutions while addressing environmental concerns.

As SVT embarks on this decommissioning journey, the focus remains on safety and sustainability, ensuring that the site’s legacy contributes positively to future energy projects.
