Greek shipowner Okeanis Eco Tankers (OET) will have a new chief financial officer from 1 December after recruiting from Borealis Maritime.

The Oslo-listed shipowner has appointed Borealis' investment manager Konstantinos Oikonomopoulos, who will replace interim CFO Thalia Kalafati, the company's treasurer.

She has been serving in the role since September when previous CFO John Papaioannou left.
