Khamis Juma Buamim is no longer at the helm of Dubai-based tanker operator Gulf Navigation Holdings.

TradeWinds has learned that Buamim submitted his resignation to the company’s board at the end of December and left the company earlier this month.

Gulf Navigation has yet to announce the appointment of Buamim’s successor and in the interim Omar Abu Omar, president of maritime and operations is said to be holding down the fort.

While no reason for Buamim’s resignation has been disclosed, his departure coincides with a new major shareholder coming on board.
