Adnoc Logistics & Services (Adnoc L&S) has lifted its total spending on LNG carrier newbuildings to more than $1.2bn, with an order for four more vessels in China.

Shipbuilding sources said the Middle Eastern shipowner has returned to Jiangnan Shipyard and signed for four 175,000-cbm vessels, bringing the tally to six. Its earlier two ships were sealed in March.

Officials at Jiangnan declined to comment, citing contract confidentiality, while Adnoc L&S did not reply to a request for confirmation.
