Pipeline Support and Stabilisation

Pipelines and structures need supporting over stretches of uneven seabed and ravines – this is called free span correction.

FoundOcean is your single-source for the design, manufacture and installation of all types of fabric formworks. In fact, we hold the record for deploying the deepest fabric formworks at a depth of 1,224m.

Our fabric formworks are a flexible shuttering constructed from woven fabric which is filled with grout in-situ. The final shape of the support is defined by the shape of the fabric formwork. Fabric formworks may also be used to raise a pipeline or structure by jacking to a desired elevation.

We have experience of installing fabric formworks for supporting and stabilising pipelines, j-tubes and risers in both preventative and curative conditions, and depending upon the environment can be deployed by divers or ROVs to undertake this work.

The techniques developed by FoundOcean for deploying fabric formworks by ROV have been successfully used at water depths of more than 1,200 metres. In addition, FoundOcean provides specialised grout mixing and pumping equipment together with experienced personnel for the successful installation of the formworks. Because FoundOcean is involved in the offshore work, all formwork designs take account of the practical aspects of installation. Detailed work procedures are provided to ensure that the diving or ROV contractor correctly applies the solutions.
