Where we work

Our worksites

Every dredging project presents unique challenges. From inland waterways to offshore installations, SUBMAR provides efficient sediment removal solutions that improve accessibility, support construction activities and keep critical infrastructure operating safely and efficiently.

TUNNELS

Efficient dredging solutions for tunnels and confined underground structures, where restricted access and challenging ground conditions require specialist equipment and experienced operators.

LOCKS & WATERWAYS

Locks and waterways require continuous maintenance to ensure safe navigation and efficient water management. Our dredging teams remove sediment, restore design depths and support maintenance projects with reliable equipment and experienced personnel, minimising disruption to daily operations.

CONSTRUCTION WELLS

Specialist dredging services for construction wells and excavation pits, ensuring efficient sediment removal and safe working conditions in confined and challenging environments.

OFFSHORE SITES

Specialist dredging services for offshore construction, renewable energy and marine infrastructure projects. Our compact equipment enables efficient sediment removal and seabed preparation in challenging offshore environments.

Dredge support for decommissioning

Supporting decommissioning operations with specialist dredging services, including sediment removal and seabed clearance around offshore structures and subsea assets
