Portovaya LNG

On a small peninsula in Russia’s northwest edge, building workers, engineers and welders are chasing records. As part of a new LNG plant, Linde’s Engineering Division is building the realtred full-containment LNG storage tank in record speed: Thanks to fast-track engineering and procurement, sophisticated construction technologies an optimized time schedule is achieved. The 42.000-cubic-metre tank was scheduled to be realized only 22 months – despite the challenging Russian winter.  

Just two hours from metropolitan Saint Petersburg, heading northwest along route E18 towards the Finnish border, one of the last exits leads to a site of birch woodlands tinged with salty sea air. This is the site of Portovaya, where a complex for lqiuified natural gas (LNG) production, storage and shipment was erected. The plant has a yearly capacity of around 1,5 million tonnes of LNG, classifying it as mid-scale.
