Corrosion Resistant Alloy Pipeline Installation for High Pressure High Temperature Requirement
This paper discusses on the methods of the installation of Corrosion Resistant Alloy pipeline for High Pressure High Temperature including its challenges and the subsequent mitigations. The experience is based on the successful installation of Anjung Gas Development Project which consists of 18” diameter X 8 km length of CRA Full Well Stream pipeline installed utilizing the DP-2 pipelay vessel. The methodology applied in the installation is via typical S-lay utilizing automatic welding system (for the pipelaying) and stalk-on (for the risers at both sides of the platforms). Additionally, Zero Radius Lay method was utilized at buckle triggers. On the existing KAKG-A platform, the riser installation is via suck-in method to avoid removal and reinstatement of the existing riser guard. Two numbers of anode sleds were utilized for cathodic protection. The scope for pre-commissioning performed was flooding the pipeline with fresh water, cleaning, gauging, hydrotesting, air drying, nitrogen purging and packing.
