Asset Protection Technology

PRP Units (Rock Bags)

Tekmar's PRP Units (Protective Restraint and Positioning Units), commonly known as Rock Bags, provide a flexible and highly effective stabilisation solution for subsea cables, pipelines and offshore structures. Designed to deliver rapid, adaptable support in challenging seabed conditions, PRP Units help improve asset stability, reduce risk and support long-term offshore performance.

A versatile and proven solution for stabilisation, free-span correction and asset protection.

Filled with graded rock or aggregate, PRP Units (Rock Bags) conform naturally to seabed contours and asset profiles, making them ideal for applications where traditional rigid solutions may be unsuitable. Combining fast deployment with proven offshore performance, PRP Units support offshore wind, oil and gas, interconnector and marine infrastructure projects worldwide.
