... the stress at the touchdown zone (TDZ) within acceptable limits and improves fatigue life when compared to a Steel Catenary Rigid (SCR). The state-of-art concept eliminates the necessity of buoys in a SLWR concept. Further, there will be saving in installation time, this combined reduces the CAPEX...

... Abstract This paper discusses steel catenary riser (SCR) design challenges subject to complex bi-modal and bi-directional seastates offshore West Africa in ultra-deepwater (2,600m). Metocean data is key to determining the design of SCRs. As offshore exploration continues in remote regions...

... Catenary Risers (SCRs) and Top Tensioned Risers (TTRs) used for the DDCV. An independent global performance was analyzed by utilizing latest environmental data, as-built information, measured VIM motion data and the latest analytical tools. It computes the riser global performance including dynamic...

... Abstract This paper introduces new classes of hang-offs for Steel Catenary Risers (SCRs) and Steel Lazy Wave Risers (SLWRs). Bending and tension loads are totally decoupled in the riser hang-offs presented. The new hang-offs can be designed for any temperature or pressure that can be supported...

... Abstract Riser-soil interactions have significant influence on the fatigue assessment of steel catenary risers (SCRs) near the touch down zones (TDZs), and can be critical in realizing a competitive SCR design and in extending a SCR design life. The motivation of the paper is to share...

... Abstract The objective of the STREAM (Steel Riser Enhanced Analytics using Measurements) JIP is to provide a measurement based foundation for SCR and lazy wave riser modelling to ensure that the fatigue response is assessed with adequate but not overly conservative parameters. To achieve...

... Steel catenary risers (SCRs) are a cost effective option for deepwater developments. Throughout industry hundreds of SCRs have been deployed and have proven to be highly reliable. Nevertheless, as the inventory of SCRs across industry ages and as operators seek to extend the lives of deepwater...

... Abstract The role of soil response on fatigue life of Steel Catenary Risers (SCRs) has been investigated through a scaled sectional SCR (cut-out section) in a geotechnical centrifuge. The SCR model simulated a section of the SCR starting at 16 ft (4.9 m) above the seafloor and extending...

... Abstract The paper provides a review of the state of knowledge regarding the impact of soil response in the touchdown point region on Steel Catenary Riser (SCR) fatigue. For almost 20 years the impact of soil-pipe interaction on SCR fatigue has received considerable attention within...

... Abstract Steel Catenary Risers (SCR) are typically subjected to vertical and horizontal motions, as well as rotations, causing the SCR to interact with the seabed within an area described as the Touch Down Zone (TDZ). The interaction between the seabed and the riser at the TDZ induces bending...

... of opportunity. Steel Catenary Risers (SCRs) are the preferred solution in wet-tree applications due to their simplicity, robustness and low Capital cost (CAPEX) and Operational cost (OPEX) compared to other riser options. Also, Top Tensioned Risers (TTRs) have their well-known advantages in allowing direct...
