Shareholders have in the past expressed concerns about Dudley's pay packet, but BP has repeatedly argued it needs to remain competitive and that its remuneration is lower than of most US companies.
In its annual report, board member Ann Dowling, chair of BP's remuneration committee, said the company delivered strong operating and safety performances throughout 2015.
"In an ever more challenging world BP executives performed strongly in 2015 in managing the things they could control and for which they were accountable," Dowling said in the report.
The company will face investors at its annual general meeting next month.
