Objectives/Scope:

The Sabah Sarawak Gas Pipeline (SSGP) is a 512 km x 36” O.D. Grade X 70 onshore natural gas pipeline that was completed in 2013 to transport 750 MMscfd of gas from the Sabah Offshore Gas Terminal (SOGT) to the Malaysia Liquified Natural Gas (MLNG) Complex at Bintulu, Sarawak, Malaysia. SSGP traverses through many different types of terrains. Two pipe parted incidents in June 2014 and January 2018 resulted in PETRONAS re-evaluating its pipeline repair and maintenance practices for pipeline constructed in geohazard active environment.

The pipe parted incidents triggered a reassessment of the weldment robustness against the...
