Mackenzie has streamlined the group management committee (GMC), consolidating some roles.
“The composition and structure of the team reflects my commitment to a relentless focus on the safe execution of BHP Billiton’s strategy,” he said.
“The team will provide the company with the right balance of skill and experience needed to lead BHP Billiton effectively in the current environment,” he said.
Petroleum division president Mike Yeager will leave his role and the company on July 1.
Diamonds and specialty products president Tim Cutt, a petroleum engineer, will return to the petroleum business as its president from July 2 but will retain responsibility for potash.
Base metals president Peter Beaven will become copper president, which will comprise all of his current responsibilities under a different title.
Former energy coal president Dean Dalla Valle will take over responsibility for all of BHP’s coal assets.
Metallurgical coal president Hubie van Dalsen will leave the company.
Former ferrous and coal chief executive officer Marcus Randolph, currently on extended sick leave, will leave the GMC once Mackenzie takes over on May 10.
Former aluminium, nickel and corporate development CEO Alberto Calderon will also leave the GMC but will remain as an advisor to Mackenzie.
Former minerals exploration president Daniel Malchuk will take over as aluminium, manganese and nickel president.
Current manganese president Tom Schutte and aluminium and nickel president Glenn Kellow will assist Malchuk with the consolidation.
Jimmy Wilson retains the title of iron ore president.
Mike Henry, Graham Kerr and Karen Wood remain part of the GMC as health, safety, environment and community and marketing and technology president; chief financial officer; and people and public affairs president, respectively.
Herbert Smith Freehills partner Geoff Healy joins the GMC as chief legal counsel and group company secretary Jane McAllon joins the GMC as governance president.
“With the company’s focus having shifted to an even greater emphasis on operational excellence, the removal of a layer of management brings the operations closer to the CEO and ensures alignment between strategic and managerial leadership,” Mackenzie said.
“All of this will be critical in driving our productivity agenda.
“The new team will be tireless in its pursuit of best in class in terms of dollars spent per tonne mined and barrel lifted, maintaining our capital discipline, delivering sustainable returns for our owners and continuing to contribute to the communities and countries in which we operate.”
In taking over from Kloppers next month, the company said Mackenzie would receive a base salary of $US1.7 million ($A1.6 million), up from his previous pay of $1.2 million.
He’ll receive a pension of 25% of his base salary, down from 36%, a short-term incentive target opportunity of 160% of base salary, reduced from a maximum 320% and a long-term incentive award for 2013 of 400% face value of base salary, subject to shareholder approval.
Incentives comprise 72% of Mackenzie’s remuneration.
Kloppers will receive his base salary of $2.2 million and pension entitlement of 40% of salary until he leaves the company on October 1, with no severance to be paid.
BHP shares dropped 3% in early trade to $A31.08.
