Browne is described by journalist and author Tom Bower as responsible for a " ruthless " programme of cost-cutting at BP that compromised safety , and thus the man most responsible for a string of major accidents including the Texas City Refinery explosion ( 2005 ) and the Deepwater Horizon explosion ( 2010 ) . Bower also accuses Browne of tolerating only " sycophants " in his " corporate court " , said to include Tony Hayward who succeeded him as BP Chief Executive . Browne has rejected Bower 's account , saying that he ( Browne ) increased the number of engineers appointed to BP
