After big crude carriers stole the limelight in the opening week of the year, the tanker sale-and-purchase market’s focus switched back quickly to smaller vessels carrying refined products.

Big players including ST Shipping — Glencore’s shipping arm — Tsakos Energy Navigation (TEN) and Navios Maritime Partners are being linked to deals worth about $300m for product carriers built between 2005 and 2011.

None of these deals have been officially confirmed so far.
