Marine demolition
We are the UK’s specialist national contractor for earthmoving, crushing & recycling, and flood, coast & marine defence works.
Removal of coastal structures and redundant sea defences
Marine demolition demands controlled execution within tidal, environmental and structural constraints. OEC undertakes the removal of coastal structures, redundant sea defences, harbour installations and marine assets with precision and regulatory compliance.
Our teams assess structural stability, tidal influences and environmental sensitivities before phased dismantling begins. Materials are segregated for recycling wherever possible, aligning with our commitment to sustain and enhance coastal environments.
Specialist long-reach excavators and heavy-duty attachments enable safe removal in challenging conditions. Operations are programmed around tidal windows to ensure safe access and minimal disruption from land or marine plant.
We sustain environmental responsibility through material recycling. We protect surrounding infrastructure and habitats during dismantling. We enhance future coastal schemes by preparing sites for redevelopment or upgraded defences or marine infrastructure.
With a proud reputation for having one of the most modern fleets, OEC continues to invest in low-emission and hybrid plant to reduce environmental impact without compromising performance. Our fleet incorporates fuel-efficient, hybrid and Stage V compliant machinery, significantly lowering carbon emissions, fuel consumption and noise levels across operations. This allows us to operate more sustainably in sensitive coastal and urban environments, while maintaining the power, reliability and productivity required for demanding marine and earthmoving projects.
Our expert operators, many with decades of coastal and marine experience, ensure consistent, reliable performance in complex and changeable environments. Their understanding of tidal conditions, ground stability and precise material placement is critical to maintaining safety, programme certainty and build quality where there is little margin for error.
OEC provides disciplined marine demolition backed by experienced personnel and reliable plant support.

Need to Know More?
OEC delivers marine demolition through phased, risk-assessed dismantling sequences that account for structural stability, tidal ranges and environmental sensitivities. Works are programmed around tidal windows and coordinated access constraints to maintain safe, controlled execution in dynamic coastal environments.
OEC undertakes the controlled demolition and removal of coastal structures, redundant sea defences, harbour assets and marine installations. This includes dismantling, material handling, segregation for recycling and full site clearance in preparation for redevelopment or upgraded coastal works.
OEC prioritises material segregation and recycling wherever feasible, recovering concrete, steel and armourstone for reuse or processing. All works are delivered in accordance with environmental regulations, with controls in place to protect marine habitats, reduce contamination risk and minimise disturbance to surrounding coastal infrastructure.
