Ports & Harbor
We provide diving services for port structures, quay walls, mooring systems, and other harbor infrastructure – safely and efficiently in tidal and confined conditions.
We provide diving services for port structures, quay walls, mooring systems, and other harbor infrastructure – safely and efficiently in tidal and confined conditions. Our teams work in challenging marine environments to maintain and repair critical port infrastructure.
Services Include
Quay walls, piers, jetties: inspection and repair
We inspect and repair structural elements of port facilities, ensuring safe berthing and mooring operations for vessels of all sizes.
Key Services
- Structural surveys, defect mapping, and targeted repairs
- Protect safe berthing and mooring operations for all vessel sizes
- Reinforcements to extend service life and reduce risk
- Photo/video documentation for asset registers
Berthing areas: cleaning and debris removal
Our divers remove accumulated debris, sediment, and marine growth from berthing areas to maintain safe navigation and vessel access.
Key Services
- Remove debris, sediment, and marine growth from berths/approaches
- Improve navigational safety and berth availability
- Works scheduled around tidal windows and port traffic
- “Before/after” media for verification and billing
Underwater concrete, sealing, and welding
We perform structural repairs and reinforcements using underwater concrete placement, sealing techniques, and welding to extend the lifespan of port infrastructure.
Key Services
- Structural repairs with underwater concrete placement
- Leak sealing and steelwork to stabilize quay structures
- Reinforcements for dolphins, piles, and sheet-piles
- QA with testing and progress records
Navigation & berth condition surveys
We keep channels, berths, and turning basins safe and open with targeted seabed assessments. Our teams check scour and obstructions, deliver geo-referenced visuals for planners and regulators, and issue rapid reports that align with dredging and maintenance windows—complete with trend insights to flag hotspots and guide budgets.
Key Services
- Seabed/approach assessments, scour and obstruction checks
- Geo-referenced visuals for planning and regulator engagement
- Rapid reporting to support dredging and maintenance windows
- Trending to anticipate hotspots and budget needs
Safe operations in tidal & confined conditions
We plan and execute works in strong currents and low visibility using task-specific procedures, equipment, and experienced supervision. Method statements meet HSE requirements, with coordinated traffic control and marine safety plans so activities integrate smoothly with port movements and keep schedules on track.
Key Services
- Procedures and equipment tailored to currents and low visibility
- Experienced supervision and method statements for HSE compliance
- Coordinated traffic control and marine safety plans
- Delivery that keeps port schedules on track
