Alafouzos family backed Okeanis Eco Tankers has secured a loan from one of its existing banks to support scrubber retrofitting.
BNP Paribas is behind the new $11m facility which will fund the equipment on two aframax and four suezmax tankers.
Okeanis told investors the loan, which has a five-year tenor, carries an interest rate of 2% over Libor.
It marks the second piece of business between the Greek shipowner and the bank this year.
In January BNP Paribas inked a loan covering one of the company’s VLCCs under construction at Hyundai Heavy Industries.
That $58.175m cheque covered 65% of the cost of the newbuilding, one of eight tankers in the series at the world’s largest shipbuilder.
Okeanis listed in the Norwegian capital markets system last year with a view to have scrubbers fitted across its full fleet with IMO 2020 in sight.
Okeanis has employed a mixture of conventional bank debt, lease financing and public equity.
