Offshore Products › Risers & Flowlines
Wellstream’s unbonded dynamic flexible risers, static flowlines and quasi-static jumpers represent key integrating technologies connecting subsea structures with surface production units.
The versatility of flexible pipe to provide this range of applications is largely a function of their structure which comprises the helical application of metallic wires and tapes, and extruded thermoplastics to form a composite pipe structure designed to address field specific constrains such as
- Pressure
- Water depth
- Temperature
- Fluid characteristics
Wellstream's dynamic riser solutions include:
- Traditional flexible riser systems for traditional FPSO developments
- Fluid Transfer Lines connecting offset risers systems to floating production units
- Export systems, or Offloading lines connecting floating production units to off-loading buoys
Static flowline systems, connecting wellhead to riser serve to maximise infrastructure layout flexibility. Wellstream’s static systems are particularly competitive for marginal field developments which are tied-back to existing infrastructure, but may also be installed through existing rigid risers as part of field redevelopment or enhancement programmes again to make use of existing infrastructure.
Quasi static jumpers used to connect top tension riser systems to topside floater pipe work, complete the portfolio, with their ability to absorb vertical movements of the production unit without transmitting dynamic loadings into the topside pipe work providing a significant advantage.
