Underwater Installation of an Environmentally Friendly Mooring System

A special revision of our 400H can be used by divers to install and environmentally friendly mooring system in depths up to 10m.

The unique hollow shaft 400H can drive ABC 60R screw anchors from the centre lugs, and then the end, of leads and 2m extensions.Hydraulics power is usually from a petrol power pack at the surface.

The driver operator maintains full control using the integral control valve. An extended torque reaction arm engages with the seabed for safety. A Mooring swivel is bolted to the final extension prior to being driven just below the seabed to prevent boat grounding damage. At maximum torque and 3:1 factor of safety the working load exceeds 40kN (4 Tonnes). The driver will also extract an anchor when necessary.
