Stolt-Nielsen plans to buy back the remaining majority of $30m in shares that had been earmarked for repurchase two years ago.
The Niels Stolt-Nielsen-led tanker owner's board of directors in March 2016 authorised the company to buy common stock up to that amount.
At the time, Stolt-Nielsen bought $1.7m in shares, leaving $28.3m for future purchases.
The shares will be purchased through open market transactions and private offerings in accordance with applicable laws and regulations, the London-based company said.
