Breakwaters
We are the UK’s specialist national contractor for earthmoving, crushing & recycling, and flood, coast & marine defence works.
Engineering and constructing robust offshore and nearshore structures
Breakwaters provide primary coastal defence by reducing wave energy before it reaches the shoreline, harbour or critical infrastructure. OEC delivers engineered breakwater construction across the UK, forming robust offshore and nearshore structures designed to sustain, protect and enhance coastal environments.
Constructed using precisely graded armourstone and core materials, our breakwaters are built to strict engineering specifications, ensuring hydraulic stability, structural integrity and long-term durability under extreme tidal and storm surge loading. Addressing how breakwaters can be constructed to withstand wave energy. each project begins with detailed planning around bathymetry, tidal cycles and access constraints, enabling controlled marine placement and accurate profiling.
Our specialist plant fleet includes long-reach excavators, high-capacity loading shovels and articulated dump trucks capable of operating in challenging intertidal and shoreline conditions. Rock placement is carried out with precision grapples to achieve specified interlock and energy dissipation performance.
We protect communities and infrastructure by forming resilient wave barriers. We sustain coastlines by managing sediment transport and reducing erosion. We enhance marine settings through careful material selection, using LGP equipment and environmentally responsible working methods, including biodegradable hydraulic oils and strict environmental compliance.
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.
Whether forming harbour protection, coastal reinforcement or offshore attenuation structures, OEC provides disciplined, programme-driven breakwater construction with full operational support and 24/7 fleet reliability where tidal windows demand it in challenging tidal windows.
