Pipeline Supports

Single or multiple reinforced concrete Pipeline Supports are used to provide a crossing for a new pipeline over an existing pipeline, umbilical or other asset on the seabed.

SPS can manufacture these to its standard designs, clients own designs or we can work with clients to develop a Support system for any particular application.

Design issues will typically include, review of seabed conditions, seabed settlement and Support footprint, restraining the pipeline on Support, pipeline bearing surface on Support (e.g. low friction/high friction/low impact etc), pipelay tolerances, handling and installation of Supports, and design life requirements.

Full documentation and certification is provided as part of a SPS standard.

Fabric Formworks


Fabric formwork is constructed from a flexible woven fabric into purpose built bags for injecting subsea with a grout/cement mixture, to form a permanent shape for:

  • Pipeline and cable crossing support
  • Stabilization and protection for various subsea structures
  • Anti-scour protection
