We build jet plough (blades) since the 90s.
They consist of one foot (the blade), in which the rinsing nozzles sit, a cone,
any number of extensions and the flushing head.
While running wires, the complete jet plough (blades) is laterally moved on the ship.
Above the flushing head the water is directed with huge pressure into the jet plough (blades),
which occurs again under the injectors from the bottom and slices a furrow into the seabed.
Through a role bow the submarine cable will simultaneously lower the blade and a built-in blade channel
will be driven into the gutter.
Jet ploughs (blades) are always following a basic principle; differ only in a small range of the cable channel.
Due to the harsh constraints, they are made of wear-resistant steel.
