Kosmos Energy has appointed Andrew Inglis as board chairman and chief executive with effect from 1 March, enabling current chief executive Brian Maxted to focus on his exploration role. Maxted, a founding partner of Kosmos, will serve as chief exploration officer and remain on the board, while current board chairman John Kemp will retire. Inglis joined Petrofac in January 2011 after 30 years with BP, most recently as chief executive of its exploration and production business.
