Our personnel have experience in the design and construction of riser systems in shallow and deepwater applications whilst Peritus’ forward focus is on dynamic risers in deep and ultra-deep waters. These changes resulted in ~$50 – 80 Million dollars in potential cost savings for the client’s flexible riser procurement. Marine Risers Riser Engineering Capabilities Peritus’ capability in Risers is founded on our leading industry personnel, with experience to develop innovative solutions. Large suction piles required for holdback, but missed by design house (analysis issues)Īfter a detailed review of the original design criteria and riser configuration philosophy, Flexlife updated the specifications of the ITT, reducing the complexity of the design which allowed two additional vendors to bid on the pipe.

Resulting hang-off angle for risers = 10deg, free hanging catenary.No iterations on layout and configurations.Details of riser modeling, environmental data, and vessel particulars are described. Thus, 26 different models of risers (HRs, SCRs, and SLWRs) were analyzed to investigate the impacts of the various critical considerations on the riser structure. Most of the understanding of VIV is based on straight riser model, flexible riser and. The stress analysis was conducted based on the fundamental thoughts of SCR and HR. Umbilical configurations were designed first, then riser configurations designed to avoid clashing with umbilicals and compression. riser (SCR) in associated with vortex-induced vibration (VIV) is.Structures included expensive PVDF, Super-austenitic carcass, sour service wires, and multiple insulation layers.Review of flexible riser modelling and analysis techniques. Resulting pipe structures were at the manufacturers limits for qualification in multiple respects. Availability of diverse computation packages for marine risers eases structural assessment.
