Abstract

In China's first deepwater project Liwan 3-1 gas field development, COOEC completed EPIC work of the SSIV system successfully. From system design to subsea facility manufacture, several technical challenges were conquered. Detailed FE analyses were carried out to study the behavior of umbilical installation and structural integrity of SUTA foundation. Theoretical static balance formulas were derived to support the detailed analyses. Another challenging work was offshore installation. Detailed installation procedures for umbilical and SUTA installation were developed. The SUTA launching and curve laying operations were both carried out smoothly. The practice accumulated good experience for such kinds of umbilical project in China.
