Greece's Top Ships has snapped up more tanker newbuildings from the private fleet of chief executive Evangelos Pistiolis.
The Nasdaq-listed owner said it is paying just $18m to a company affiliated with its boss.
In return it gets 100% ownership of three Marshall Island companies that each own one ultra-high specification scrubber-fitted 50,000-dwt MR vessel.
All are under construction at Hyundai Mipo Dockyard (HMD) in South Korea.
