Okeanis Eco Tankers, an owner of 14 large, modern tankers, has posted the biggest annual profit in its six years as a public company.

On Thursday, the New York-listed company reported net income of $145.3m for 2023, up from $84.6m in the previous year.

Profitability slowed down in the second half, given relatively weaker markets for the company’s eight VLCCs and six suezmaxes.
