Oil giant Shell has confirmed the discovery of a suspected unexploded ordnance near a crucial gas pipeline in the North Sea. The find, made during a routine inspection in December 2024, has prompted an investigation and raised questions about the safety of offshore energy infrastructure.
The potential explosive device was found approximately 80 kilometers (50 miles) east of Shetland, in close proximity to the Far North Liquids and Associated Gas System (FLAGS) pipeline.
This pipeline is a critical component of the region’s energy infrastructure, responsible for transporting gas from the Northern North Sea to the St Fergus Gas Terminal near Peterhead, Aberdeenshire.
A Shell spokesperson stated: “We are working with a third party to further investigate and fully identify the object. We continue to liaise with relevant authorities including the Maritime Coastguard Agency, and have positioned a guard vessel at the location.”
The company has assured that the FLAGS pipeline is currently operating normally, despite the concerning discovery.
The presence of unexploded ordnance in the North Sea is not uncommon.
Last March OEG Renewables business Hughes Subsea identified and undertook clearance work of UXO at ScottishPower Renewables’ 1.4GW East Anglia Three offshore wind farm.
Brandon Mason, an archaeologist with Maritime Archaeology Ltd, commented in 2023 that offshore development work is likely to lead to an “avalanche” of such discoveries. The North Sea has a history of military activity, particularly during World War II, which has left a legacy of potential hazards for modern offshore operations.
In response to the discovery, Shell has taken immediate precautions. A guard vessel has been positioned at the location to ensure safety while further investigations are conducted.
The company is working closely with relevant authorities, including the Maritime Coastguard Agency, to manage the situation effectively.
This incident highlights the ongoing challenges faced by the offshore energy sector. While the discovery of unexploded ordnance is not unusual in the North Sea, it underscores the importance of regular inspections and robust safety protocols in maintaining the integrity of critical energy infrastructure.
