Espirito Santo: Design and Operational Experience of the Use of Steel Risers on a Turret-Moored FPSO
The floating production, storage, and offloading (FPSO) facility Espirito Santo, located offshore Brazil in the Parque das Conchas (BC-10) field, is the world’s first turret-moored FPSO facility to use steel risers for fluid transfer.
Dynamic Plastic Deformation of Deepwater Steel Catenary Risers Under Extreme Cyclic Compressive Loading
Steel catenary risers (SCRs) on a large-heave-motion vessel are susceptible to compression in the riser touchdown zone (TDZ). In this paper, a finite-element-analysis modeling method is presented to simulate deformation, pipe ovality, and local pipe buckling.
Study on Severe Slugging in an S-Shaped Riser: Small-Scale Experiments Compared With Simulations
Severe slugging is characterized by large pressure fluctuations at the base of the riser and is accompanied by fluctuations in fluid delivery from the top of the riser. This instability has negative effects on downstream equipment.
Implementing a Deepwater-Pipeline-Management System
There are few deepwater-pipeline operators with expertise in pipeline repairs. This paper describes a strategy developed and implemented on deepwater-pipeline intervention, based on a deepwater operational experience built over a decade.
HIPPS-Based No-Burst Design of Flowlines and Risers
A methodology is proposed for design of subsea flowlines and risers coupled with a subsea high-integrity pressure protection system (HIPPS) for fields with high shut-in tubing pressure (SITP).
