Energy - Marine

We deliver specialist marine and landfall works for the energy sector, forming the critical interface between onshore infrastructure and offshore assets. These projects demand precise coordination, robust engineering and disciplined execution, particularly where pipelines, cables and tunnels transition through complex coastal and nearshore environments.

Our capability spans landfall structures, coastal and nearshore works, shafts, cofferdams and enabling works, supporting the installation and protection of offshore transmission cables, pipelines and subsea connections. These elements are often delivered in conjunction with trenchless tunnelling methodologies, including HDD, Direct Pipe and segmentally lined tunnels, to minimise environmental impact and reduce disruption to sensitive intertidal and shoreline zones.

Our engineering approach is grounded in a deep understanding of complex geotechnical conditions, tidal behaviour, metocean influences and environmental constraints. Marine projects require careful integration of construction sequencing with tidal windows, weather exposure and offshore installation programmes. We plan works meticulously to manage these variables while maintaining safety, quality and programme certainty.

We ensure that all activities are delivered in compliance with applicable marine regulations, environmental permits and recognised British and international standards. Environmental management is embedded throughout delivery, with particular attention to coastal habitats, water quality and sediment control. Close coordination with offshore installation contractors ensures seamless integration between marine and terrestrial works.

Our experience includes involvement in major marine energy schemes such as Aramis, a significant carbon capture and storage development, and the Emergency Sea Outfall (ESO) project in Kuwait, where technically demanding marine and tunnelling interfaces were successfully delivered. These projects demonstrate our capability in managing offshore recovery operations, nearshore construction and complex landfall connections in challenging environments.

By combining marine engineering expertise, trenchless construction capability and rigorous assurance processes, we provide a trusted marine works capability that enables safe, resilient and long-term connections between offshore and onshore energy infrastructure in the UK and internationally.
