Essoraffineriet på Slagentangen, Oil refinery in Tønsberg, Norway
Essoraffineriet på Slagentangen is a petroleum processing facility situated on the shores of Oslofjord near Tønsberg. The plant spreads across extensive industrial grounds with numerous structures and equipment dedicated to refining crude oil into various products.
Operations began in autumn 1960 under Esso Norge, an ExxonMobil subsidiary. Prime Minister Einar Gerhardsen attended the official opening ceremony in 1961, marking the facility's importance to Norway's industrial development.
The refinery shaped the local economy by providing steady employment and establishing the region as an industrial center. It remains visible in daily life as a major employer and a defining feature of the community's identity.
Access to the refinery itself is limited since it is an active industrial facility. Views of the plant are available from nearby roads and public areas that provide vantage points to see the main structures from a distance.
The refinery's 60-meter chimney is the tallest structure in the Vestfold region and shapes the skyline of the fjord area. This distinctive feature serves a functional purpose while also becoming a recognizable landmark in the local landscape.
