Swiss tanker owner and operator Advantage Tankers has entered the MR product tanker sector, placing an order for four 50,000 DWT MR product tankers with Guangzhou Shipyard International (GSI), a subsidiary of China State Shipbuilding Corporation (CSSC), according to shipbroking and market sources. Delivery of the vessels is expected by 2029, though the contract price has not been disclosed. The order marks Advantage Tankers' first move into the MR segment. The company, which began operations in 2015, currently manages a fleet of 28 tankers comprising six VLCCs, 11 Suezmaxes, four Aframaxes and seven LR1 product tankers. It has been an active newbuilding buyer in recent years, previously focusing on crude carriers, particularly Suezmaxes and Very Large Crude Carriers (VLCCs), ordered from shipyards in China and South Korea. Fleet data on Advantage Tankers' official website lists 12 vessels in its existing newbuilding program, including four 320,000 DWT VLCCs from Hanwha Ocean, four 157,000 DWT Suezmaxes from DH Shipbuilding, and additional units from Dalian Shipbuilding Industry Corporation (DSIC), with deliveries scheduled between the second quarter of 2027 and the third quarter of 2029. The newly reported MR tanker order has not yet been added to that published list. GSI has emerged as a leading yard for MR product tanker construction, having secured orders for more than 20 vessels in this segment so far in 2026, including the Advantage Tankers contract.
