US owner Harley Marine has reportedly contracted two new bunker vessels in China.
The 7,500-dwt pair are due in December this year from Huangpu Wenchong Shipbuilding, broker Clarksons said.
No price has been revealed for the ships.
Harley last year ordered two ocean-going barges at Gunderson Marine in the US.
Confirmation of any new deal has been sought from the owner.
