The tanker arms of Vietnam’s PetroVietnam and Indonesia’s Pertamina are reported to have bought Sumitomo-built aframax tankers from two leading Greek shipowners.

Tanker brokers based in Europe claim that PetroVietnam’s tanker arm PVTrans has purchased Tsakos Energy Navigation (TEN)'s 105,000-dwt Sakura Princess (built 2007).

A firm price of $23m has been suggested for the deal. VesselsValue said the Sakura Princess is worth only $18.2m, while Maritime Strategies International indicated a range of $17.2m to $20.2m.

PVTrans and New York-listed TEN did not respond to requests for comment.
