Norway's Rasmussen Group had a record year in 2019 on the back of strong results in the seismic survey sector.
The diversified Kristiansand-based company saw its pre-tax profit increase to NOK 2.32bn ($238m) last year from NOK 344m in 2018.
This is largely due to Rasmussen writing up the value of the shares in seismic company Shearwater Geo Services by NOK 2.7bn.
