Adamantios Lemos-controlled Unisea Shipping has halved an order for aframax tankers at Samsung Heavy Industries (SHI).

Unisea turned to the South Korean yard for a pair of 115,000-dwt crude oil tankers in March 2015 and followed it up by talking up two options that August.

Now, market sources advise that the contract has returned to just two vessels.

Hulls 2192 and 2193 are set for completion in July and September this year and will still join the Greek owner’s fleet.
