Pangkah Block PSC is located in Offshore East Java. It’s a highly sensitive area due to massive fishing activity on and around 700 square kilometer area, as well as thousand hectares of fishpond located adjacent to the south of block’s boundary. Ujung Pangkah Field is the only producing field in Pangkah PSC block so far, located in active delta branches of the Bengawan Solo River. Large amounts of sediment materials are being transported from the land outflow to the sea by the Bengawan Solo River. It is estimated Bengawan Solo river delta has a huge mud sedimentation flow that deposited 17 million tons of mud per year. Operating in such harsh condition, Pipeline Integrity in Ujung Pangkah is critical to company’s success. Loss of pipeline integrity can result in leaks of crude oil or natural gas, which can negatively impact the safety of community, environment, and Pangkah Field operability. Pipeline integrity should be maintained through proper design, proper installation and robust maintenance program that consist of proper monitoring, proper inspection and proper intervention when required. Geomatics can be described as science and technology to collect, process, manage, analyze and display geospatial data and information. It includes the tools and techniques used in land and marine surveying, remote sensing, cartography, geographic information systems (GIS), global navigation satellite systems (GPS, GLONASS, Galileo, Compass). Geomatics have played an important role to promote Pipeline Integrity in Saka Indonesia Pangkah Limited (SIPL). This paper will describe how seabed stability and geomorphology survey helped SIPL operation team finding the root caused of 6” Gas Injection Pipeline Rupture in April 2011. The use of Geographic Information System, High Resolution Satellite Imagery and Intelligent Pigging data to identify and monitor construction activities around 20” Sales Gas Pipeline from OPF to PLN will also be discussed.
