Sea Tank Chartering-affiliated holding company Tank AS suffered a slump in annual profits for 2017, although the Norwegian chemical tanker owner and operator has experienced a better market this year.

Last year's result was partly due to higher bunker prices, as well as a somewhat weaker spot market for carrying chemical cargoes. The company adversely affected by currency fluctuations.

Tank AS logged a pre-tax profit of NOK 12m ($1.5m)
