Abstract

Due to H2S corrosion, the process piping in SDRB of HYSY111 FPSO dynamic riser system will be in the risk of oil leakage. In order to ensure the oil field production facilities integrity, it is necessary to find a solution to lay a new SDRB to replace the existing SDRB. This paper is to summarize the SDRB replacement strategy, the new SDRB structure design, mudmat & scour protection design, dynamic cable tray design and installation tolerance analysis& control method. The design idea and method described will provide reference for other similar subsea products design in South China Sea.
