PRP Units

Pipeshield’s Precise Rock Placement Units (PRP’s) are designed for easy handling via a single point lift, optimising handling and installation time.

PRP Units

The Precise Rock Filter Unit, or PRP, is a cost-effective alternative to rock dumping. Made from marine grade netting complete with masterlink assembly for a single point lift, the units can be handled and installed easily using a much smaller capacity vessel or land-based crane.

The stone-filled net is designed to encase the stone preventing it from breaking down or migrating from it’s intended location.

PRP units can be easily positioned by divers or ROV for a wide number of applications within Oil & Gas, Renewables, and the Marine Civils sector.

Pipeshield supply the units in 250kg, 2T, 4T & 8T sizes, although alternative sizes can be manufactured to suit. Pipeshield can also fill the units using graded rock sourced locally to the project, which significantly reduces transport costs.

Multiple units can be deployed at the same time using Pipeshield’s bespoke design lifting beam.

Rock placement units can be used as a temporary or permanent solution and in subsea conditions will over time encourage marine life becoming a permanent habitat.
