A London panel this week ruled against the Dubai-based tanker owner in the case against Chinese yards Zhoushan Jinhaiwan Shipbuilding, Grand China Logistics Holding and HNA Group.
Gulf Nav ordered the vessels in 2011 but the yard subsequently cancelled the contract after the owner tried to change the terms to make them more fuel efficient.
Including legal costs and interest, the company has provided for a loss of AED 230.2m
