Statoil said on Wednesday that five people were injured while working at the Sture terminal in Norway.
The Norway-based company said that five people were exposed to hydrogen sulfide (H2S) gas while working at a treatment facility for oily water inside the terminal area.
The five people were sent to Haukeland Hospital and their relatives have been notified.
Further details about the injuries have not been disclosed yet.
Emergency services and relevant authorities were notified of the incident.
Statoil mobilized its emergency response organization at both Sture and in Stavanger.
The company said that gas readings were carried out and there is no risk of further exposure.
Statoil has cordoned off the area and police have begun investigating the incident.
The Petroleum Safety Authority Norway will also investigate the matter.
Statoil will also carry out its own investigations to determine how the exposure occurred.
Statoil said it is “still too early to provide information about the cause of the incident.”
The Sture terminal is located in the Øygarden municipality in Hordaland.
The terminal receives crude oil and condensate from the Oseberg area through 71 mile pipeline and crude oil from the Grane field and Edvard Grieg field through a 113 mile oil pipeline.
About 200 to 500 ships call in at Sture each year, according to Statoil.
