Greek owner Okeanis Eco Tankers has promoted treasurer Thalia Kalafati to chief financial officer on a temporary basis to replace the departing John Papaioannou.
Kalafati was previously the company's CFO and oversaw the Alafouzos family-controlled company's listing on the Euronext Growth market, formerly the Merkur Market, in July 2018.
Okeanis said Papaioannou had decided to step down from his position from 1 September.
He will pursue "opportunities outside of crude tanker shipping", the company added.
Okeanis told TradeWinds the new role will be a broader one that is mainly unrelated to shipping.
Kalafati will serve on an interim basis until a suitable permanent replacement is found.
Candidates identified
Chairman and chief executive Ioannis Alafouzos thanked the outgoing CFO for his contribution to the shipowner during the past three years, and wished him success in his future endeavours.
"The board has commenced a comprehensive search process for John’s replacement. We have identified a highly qualified shortlist of potential candidates, and will provide a market update in due course," he added.
Papaioannou has more than 12 years of shipping experience in finance, capital markets and research.
He was previously the head of strategy, research and investor relations at BW LPG in Singapore.
Cyprus-born Kalafati joined the Alafouzos family's private Kyklades group in 1992.
Between 1981 and 1992 she was senior account manager at Barclays Bank in Piraeus.
In the second quarter, the Oslo-listed VLCC and suezmax owner logged a net loss of $8m against a profit of $37m last year, as revenue fell to $47m from $81m.
