Two Chinese shipyards are being named as having won product tanker newbuilding deals from Tsakos Energy Navigation.
Sources linked Singapore-listed Yangzijiang Shipbuilding and privately owned New Times Shipbuilding to a series of scrubber-fitted 75,000-dwt vessels announced last week.
Shipbuilding sources said Yangzijiang would construct one vessel and New Times up to four ships, with two firm and two optional ships.
