HOUSTON –The mini-Lazy wave SCR configuration is the most promising for application in deepwater West Africa, said Mason Wu of Acergy at the Deep Offshore Technology International Conference and Exhibition today.
Along with the flexibility and cost effectiveness of the bow turret moored FPSO, SCRs have been selected because of robustness and technology availability. Acergy and several operators investigated various configurations before centering on the mini-Lazy wave design.
"The mini-Lazy wave SCR configuration is the most promising solution due to better fatigue performance and its ability to avoid compressions at the touch-down point," said Wu. The preliminary study indicated that the mini-Lazy wave is promising because of the installation method.
The detailed study will assess installation, the optimum configuration for installation, and the overall performance of the design. VIV strakes, buoyancy modules and TDP interaction also will be on the test agenda, Wu said.
