Greece's Okeanis Eco Tankers has made its case for an upturn in fortunes later this year, despite the second quarter shaping up to be even worse than the first three months.

The Oslo-listed owner of VLCCs, suezmaxes and LR2s said rates remain depressed in a market still "fundamentally long on ships".

But the company added that asset values have risen significantly in anticipation of market recovery and supported by strong time-charter levels.
