Swedish owner Concordia Maritime is preparing to sell a suezmax against a backdrop of rising asset values.

The Stena-controlled company said it is marketing the chartered-in 159,000-dwt Stena Supreme (built 2012), which is valued at $37.5m by VesselsValue.

The ship remained employed in the spot market during the first quarter and had average earnings of $14,600 per day, up from $13,100 per day in the same period of last year.
