Pipeshield can supply bulk aggregates in special subsea rated bulk bags. A simple filling of scour holes, free-spans and supports can be carried out using sand and grout bags
Used as a method of bulk rock or gravel deployment, our subsea rated drop bags are designed with a large chute in the base and lifted and activated using one of our standard quick-release frames or beams. Commonly available in 1t & 2t sizes, we can source and supply pre-filled bags using locally sourced rock or aggregate. Rock can be supplied certified to a certain grade or density as required.
Rigged up to one of our specialist frames or beams, multiple bags can be installed simultaneously and activated either by a diver, ROV or using our hydraulic release kit (HRK)The bag is then recovered to the surface. This method can offer huge cost reductions compared to conventional rock dumping as a much less capable vessel is required.
Pipeshield supplies various Grout, Sand and Gravel products for use in offshore and onshore applications.
We offer a vast selection of different products, the most common being a 1Te offshore rated bulk bag with a minimum safety factor of 10:1. This ensures safe deployment through the wave zone and can be bulk filled or packed with 25kg, 40kg or 50kg individual bags. These are manufactured in polypropylene as standard although they can be supplied in biodegradable hessian sacks or double lined for extra durability.
Pipeshield can also offer larger 2Te offshore rated bulk bags with double the weight capacity.
