Efficient cable burial

The power cable plough is specifically designed for the efficient burial of cables in shallow water. It features a robust chassis that can withstand tow forces up to 180t, to provide cable burial in hard seabed conditions. The power cable plough has a proven track record for cable burial across a number of offshore projects. 

  • raked share design maximising trench depth and plough stability 
  • symmetrical share design reduces tow force 
  • crane launch option available 
  • battery powered version available to reduce deck equipment and catenary handling requirements.

Innovative share design

Unlike other ‘vertical  knife’ ploughs, the forward rake of the Royal IHC plough share creates an additional down force during operation. This ensures consistent and reliable product burial, even in stiff clays and sands. 

Battery or umbilical powered plough

As well as the standard umbilical powered plough, Royal IHC have developed a battery powered option. This would eliminate any associated cost with an umbilical e.g. winch, flotation buoys, installation, etc. as well as freeing up deck space and reducing operational complexity and risk.
