Subsea Rock Bags – 2T, 4T, 5T & 8T | Scour Protection & Pipeline Stabilisation Units
Oceanic Supply's Subsea Rock Bags are pre-filled, high-density filter units designed to deliver immediate and long-term stabilisation for offshore and subsea applications. Available in 2T, 4T, 5T, and 8T capacities, these rock bags conform naturally to seabed contours and infrastructure, making them ideal for scour protection, pipeline support, and gravity-based anchoring.
Key Features:
Available Sizes: 2T, 4T, 5T, and 8T (pre-filled with graded rocks)
Construction: UV-stabilised, marine-grade mesh netting
Central lifting eye for safe crane or ROV deployment
Self-forming to seabed and subsea assets
No diver intervention required
Reduces reliance on concrete mattresses and grout bags
Applications:
Scour protection for offshore wind turbine foundations
Subsea cable and pipeline stabilisation
Gravity anchoring for mooring systems
Flowline and flexible riser support
Environmental mitigation in erosion-prone areas
