Shipowner Adnoc Logistics & Services (Adnoc L&S) has pencilled in an order for up to six VLCC newbuildings worth more than $500m at South Korea’s Daewoo Shipbuilding & Marine Engineering, as the company moves to grow its crude trading fleet.

Brokers and shipbuilding sources said Adnoc L&S, which is the shipping arm of Abu Dhabi National Oil Co (Adnoc), has signed a letter of intent (LOI) for three firm VLCCs and a trio of optional berths.
