The project
The Oil & Gas twin onshore pipeline system in the harsh subarctic environment of Sakhalin Island in the Russian Far East is a major component of one of the world’s biggest integrated oil and gas projects. The pipeline connects the Piltun-Astkhskoye and Lunskoye field’s landfalls in the NE of Sakhalin Island to the LNG Plant & Oil Export Terminal in the South.
The design, carried out at Saipem’s high value engineering centres in Italy, France and Russia, as well as the construction activities conducted in a very remote area, required overcoming significant challenges such as construction under extreme climatic conditions with temperatures often below 45°C and permafrost several meters deep, across varied terrains; mountains with steep slopes, swamps, ponds; crossing more than 1,000 lakes and rivers, seismic zones, forests and unexploded ordnances.
