Precision Rock Placement Unit (PRP)

 

The PRP units consist of 3mm polyester, 25mm mesh with 14mm high strength lifting ropes. The stone filled net unit is designed to encase the stone, preventing it from breaking down or migrating from its intended location

PRP boasts a one point lift and is easily positioned by diver or ROV for a multitude of applications within the Oil & Gas, OWF and Marine Civil sectors.

  • Multiple units can be deployed at the same time using Pipeshield’s lifting beam.
  • Can be installed as a temporary or permanent solution for subsea asset protection.
  • Units will over time encourage marine life and become a permanent habitat.
  • Rock Shield products provides a more accurate alternative to rock dumping.
  • PRP units are highly flexible and are very adapting to undulant geography of river and sea beds.
  • Typical applications include protection and stabilisation of pipelines, cables, infill of subsea trenches and free span correction.
