Capabilities
Assembly work
Components that must be positioned below water need accurate handling, secure fixing and verification. We carry out assembly work as part of a contractor's programme, coordinating directly with the site team.
Applications
- Bolting and fixing of steelwork
- Fitting of fenders, ladders and guides
- Installation of pipes and cable ducts
- Positioning of precast elements
- Fitting of gate seals
Structures
- Lock gates
- Quay furniture
- Jetties and pontoons
- Intake and outfall structures
Method
Fit-up is prepared dry wherever possible: tooling, torque values and lifting arrangements are agreed before the dive. Underwater the team works to a fixed sequence with topside confirmation at each hold point.
Equipment
- Hydraulic torque tools
- Lifting bags and rigging
- Underwater drilling equipment
- Video verification
Safety
- Lifting plan and load control
- Tool tethering
- Pinch and entrapment assessment
- Communication discipline during handling
