(SURF) Subsea Subsea Umbilical Risers And Flowlines Installation & Operation

Fairtex provide subsea solutions such as subsea umbilicals, risers and flowlines (surf). we provide tie-back solutions between new wellhead locations and existing processing facilities. this is a turnkey solution from concept to detailed design, procurement, and through installation and commissioning.

Our engineering and project management resource works with our client’s and will select the optimum solution for any subsea-tieback project.

Our SURF Solutions

• Engineering, design and procurement of flowlines, umbilicals, risers and associated accessories


• Installation engineering


• Installation of flowlines, risers and umbilicals


• Installation of manifolds, jumpers and spools


• Trenching and alternative protection methods including rock dumping

Our capability extends to design services for structural repair and riser routing, modification, configuration and installation studies, supporting projects 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.

We are at the forefront of subsea technology, establishing new industry standards, writing SURF industry guidelines, authoring the latest riser software and leading technology development.

Flexible Pipe Experience

IMPULSE GROUP provide technical support and has experience covered a wide variety of subjects from early FEED analysis through to manufacture, installation, and integrity management. We offer a dedicated flexible pipe design and integrity service with ongoing operations globally with significant engineering and support resource to client

Our Installation Ability Covers The Following

○ Layability analysis of rigid flowlines and sealines (J-lay, S-lay)
○ Installability analysis of flexible flowlines, risers and umbilicals with estimation of installation loads in the various scenarios/phases, among which:

• Initiation from the FPSO.


• Pulling head over boarding and lowering to depth.


• Connecting risers/umbilicals to FPSO pull-in winch.


• Pulling-in up to the Hang-Off point connection.


• Buoyancy Section installation if any


• Lay away towards the subsea structures and Lay-Down of the End Connector (riser) / UTA (umbilical).

○ Static and dynamic installation analysis of rigid pipelines, including:

• Start-up and laydown


• Shore pull


• Normal laying


• Contingency scenarios (dry and wet buckle)

○ Above Water Tie-In analysis
○ Pulling heads design (Start-up, abandonment and contingency heads)
○ Lifting analysis of expansion loops, spools, jumpers, risers, supports & structures
○ Transportation Analysis
○ Pipe stacking
○ Sea fastening
