Herbjorn Hansson's Nordic American Tankers has made perhaps its most aggressive expansion move with the addition of four suezmaxes.
New York-listed NAT will splash out $106m to buy the quartet in a swoop that will take its fleet to 30 ships.
While NAT has not named the ships individually, it does say they are four sisters from a world class shipyard and will enter the fleet this summer.
