to 1.2 metre spacing intervals to suit the cable weight.

Seaflex Dual Boom Floats are a range of cable floats designed for occasions when project parameters or vessel limitations require that the most efficient way to install buoyancy onto the cable would be to fit individual units from a workboat once the cable has exited the stern of the barge. Dual BoomTM range of cable floats offers up to 600 kg in buoyancy.
