Subsea Structures

Our subsea structural services support both greenfield and brownfield projects. Delivered by a multi-discipline team, we provide robust and proven solutions from initial concept development through detailed design and beyond.

Our services extend from complex manifolds and drill centres to the less complex structures. 

Our broad range of design experience includes:

  • Concept select
  • FEED
  • Detailed design
  • Complex finite element analysis
  • On-site site supervision of fabrication

For greenfield developments, our design competency covers complex subsea production manifolds in open water to small structures located in fishing exclusion zones, and everything in between. Our design approach accommodates all external factors which influence configuration, such as tie-in and fishing requirements.

Our integrated project team addresses all design aspects, including pipework routing, equipment configuration and foundation design, to offer a one-stop service. Our niche experience is a constant thread through our design work; for instance, pipework is designed by a team with extensive experience in highly specific fatigue issues.

With over 15 years of experience in completing rigid riser projects, our strength and skills in the design of retrofit risers and associated assemblies for brownfield facilities is unparalleled. 

Our capability offering expands to provide design services for structural repair and riser routing, modification, configuration and installation studies, supporting the project through the fabrication and installation phases.  In addition to our core structural and piping design service, we also provide tender and fabrication assistance with both installation and decommissioning studies.
