British oil major BP on Thursday trimmed its executive team down to 10 members and announced William Lin as the new head of the firm’s oil and low carbon energy business.

Lin replaces Anja-Isabel Dotzenrath, who will be retiring from the position.

The company also announced Emeka Emembolu as the new lead of BP’s technology functions, taking over from Leigh-Ann Russell, who is due to leave the group.

BP said that it was simplifying its organizational structure to support its delivery of the priorities outlined earlier this year “to grow the value” of the business.

“As I set out in February, bp’s destination from IOC to IEC is unchanged – and we need to deliver as a simpler, more focused and higher value company,” BP CEO Murray Auchincloss said in a statement.

“These changes will help us do just that, reducing complexity within bp, allowing our team to focus on delivering our priorities and growing the value of bp,” he added.

Shares of London-listed BP traded 0.6% lower on Thursday morning.
