The UK Government Implements New Measures to Reduce Harmful Noise During Offshore Wind Farm Construction

The UK government is taking proactive steps to address the challenges faced by developers of offshore sites, particularly wind farms, in dealing with harmful noise during construction. One of the key issues they face is the presence of unexploded ordnance from the First and Second World Wars on the UK seabed, which can pose significant risks during project development.

Recent reports indicate that there are over 300,000 pieces of unexploded ordnance in UK waters, with estimates suggesting the number could be as high as 500,000. In light of these findings, the government has introduced new regulations to ensure the safe disposal of such ordnance during offshore construction activities.

Shell’s recent discovery of an unexploded bomb near one of its gas lines in the North Sea highlights the urgency of the situation. Similarly, the uncovering of numerous ordnance during surveys for the Moray West project underscores the need for enhanced safety measures.

Dame Joanna Lumley, a prominent British actress and activist, has been leading the campaign Stop Sea Blasts, advocating for the use of advanced technologies in disposing of underwater munitions.

Government’s Plan for Change

The UK Government’s Plan for Change, launched in December 2024, aims to accelerate the transition to renewable energy and revitalize British industry. Central to this plan is the development of clean power systems by 2030, with a focus on reducing harmful noise levels in the seas.

Under the new provisions, developers are required to adopt low-noise disposal methods for ordnance clearance, with high-order detonations permitted only under exceptional circumstances. Additionally, efforts to minimize underwater noise during offshore wind turbine installation are now mandatory, with plans for setting future noise limits through public consultation.

Industry Collaboration and Innovation

The government has collaborated with The Crown Estate’s Offshore Wind Evidence and Change program, as well as industry experts, to explore quieter technologies for bomb clearance and pilot noise limits during construction. These initiatives aim to streamline the construction process, prevent delays, and ensure the protection of marine life.

Marine Minister Emma Hardy emphasizes the importance of balancing offshore wind development with environmental conservation, stating, “We need to protect the vulnerable animals of our seas while expanding offshore wind to make Britain a clean energy superpower.”

By implementing these measures, the government seeks to facilitate the construction of offshore wind projects while safeguarding marine ecosystems and ensuring sustainable energy growth in the UK.
