Where we work
Our worksites
From ports and bridges to locks and industrial infrastructure, our diving teams support construction and maintenance projects in demanding underwater environments.
PORTS & HARBOURS
Our diving teams support port authorities and contractors worldwide with inspection, maintenance and repair of quay walls, fenders, mooring structures and berths. We work in busy operational harbours, minimising downtime for terminal operations. From routine surveys to emergency repairs, we keep port infrastructure safe and fully operational.
MARINE STRUCTURES
We provide underwater inspection, maintenance and repair services for jetties, piers, breakwaters and other marine structures exposed to constant wave and current loads. Our divers assess structural integrity, carry out concrete and steel repairs, and support new construction works below the waterline. Every project is tailored to the specific environmental and structural conditions on site.
LOCKS & WATERWAYS
SUBMAR supports the inspection and maintenance of lock chambers, gates, sills and waterway infrastructure, ensuring safe and reliable operation of these critical assets. Our teams work closely with waterway authorities to plan interventions around lock schedules, minimising disruption to shipping traffic. Services range from routine inspections to complex repair works.
INDUSTRIAL INFRASTRUCTURE
We carry out underwater inspection, maintenance and repair works for industrial sites with water-based infrastructure, such as cooling water intakes, discharge structures and pipelines. Our divers work in demanding industrial environments, often under strict safety and operational constraints. We help clients keep critical infrastructure running safely and efficiently.
WATER TREATMENT PLANTS
Our divers support water treatment facilities with the inspection, cleaning and maintenance of tanks, basins, intake structures and pipework, without requiring plants to be taken fully out of service. This allows operators to maintain continuity while ensuring their infrastructure remains in optimal condition. We combine technical diving expertise with a clear understanding of process-critical environments.
