... A technical study of an innovative steel catenary riser (SCR) installation technology is presented in this paper. This installation technology maneuvers the hull through ballasting to align its riser porch with the riser, which is philosophically different from conventional riser installation that relies...

...IRREGULAR WAVE SIMULATION AND ITS IMPACT ON RISER EXTREME RESPONSE FOR A PRODUCTION SEMI Shaosong Zhang1, Yongming Cheng Keppel FloaTEC LLC Houston, TX Yuanlang Cai, Ning He, Xiaolong Yang, Zhi Cao COOEC Tianjin, China ABSTRACT Steel Catenary Risers (SCRs) are widely used in deepwater and ultra...

... Abstract In order to enhance competitiveness of rigid risers for the Brazilian pre-salt, great effort has been devoted to study the feasibility of Steel Catenary Risers (SCR) directly connected to Floating Production Storage and Offloading (FPSO) units, where cost savings are expected from...

... to handle the full iceberg load • With and without crude oil storage in hull • Sacrificial or non-sacrificial mooring or risers • Steel riser configurations (freely hanging catenary, SCR vs. lazy wave, SLWR) • Hull with and without riser support Buoy • Location of mooring fairleads (on Upper hull...

... is conducted using a Monte Carlo simulation to evaluate the probability of failure based on incomplete ILI data and statistical characterization of other pertinent parameters. The results are compared against the conclusions of deterministic analysis. Corrosion Pitting Fitness for Service SCR Riser...

..., and that by only adding a corrosion allowance to account for loss of burst capacity, an inadequate design can easily result.

... The complex nature of seabed interaction with steel catenary risers (SCR) in touch down zone (TDZ) of SCRs makes serious difficulties for engineering design industry. Design must ensure that the curvature remains well within elastic limits, and that fatigue damage remains acceptable during...

... This paper presents a design of a deep draft wet tree semi-submersible with steel catenary risers (SCRs) for 4,000 ft water depth in the Gulf of Mexico (GoM). The integrated system of hull, mooring, and SCRs is discussed. The design challenges of SCRs are highlighted and results of SCR strength...

... Steel Catenary Risers (SCRs) are commonly used in deepwater field developments due to the cost benefits associated with their relatively simple geometry. Installation of SCRs by reel lay is generally the most cost effective approach. One of the major design challenges for SCRs is ensuring...

... The steel catenary risers (SCR) respond non-linearly to FPU motions, especially in extreme environments such as 100-year and 1000-year hurricanes. One of the design challenges is an accurate estimate of SCR response based on limited realizations. Due to the nonlinear nature of SCR response...

... joint or SCR seabed interaction can be modeled using springs and dashpots. VIVA calculates riser natural frequencies and mode shapes and also has the flexibility to import external modal solutions. In this paper, the applicability of VIVA for the design of straked steel catenary risers (SCR) and top...

... 22 05 2009 Several initiatives have been undertaken by the operators, engineering companies, product manufacturers, and regulatory bodies to enable increased use of steel catenary riser (SCR) design in development of deepwater and ultra-deepwater fields. Some of these efforts focus...

... Until recently, the feasibility of connecting Steel Catenary Risers (SCRs) to monohull FPU / FPSOs (Floating Production Units / Floating Production Storage Offloading) had not been proven for deepwaters offshore Brazil. Extreme deepwater applications have required the use of steel risers...
