Former Lloyd’s Register chief executive Richard Sadler has been appointed to a leading post at Peter Livanos’s GasLog and its spin-off GasLog Partners.

Sadler, who joins from the Foresight Group, replaces the retiring Graham Westgarth as chief operating officer of both companies.

Westgarth, who became a director of GasLog this summer, will work with Sadler to aid the transaction following his arrival next month, a statement says.
