Arrogant attitudes persist throughout petroleum management, many poor decisions are made as a result of ignoring contributions of experienced staff who aren't legacy deepwater employees due to ego.
Much of the drive for efficiency and continuous improvement has basically been undoing the costly mistakes and policy initiatives of previous management regimes despite management's continuous backslapping for doing themselves a great job.
Little to no accountability for poor results or mistakes, everything is chalked up as learning experiences and responsible managers are just shuffled around. Many supervisors are inexperienced, ineffective or both as a result.
Much time is wasted preparing and reworking presentations for management that end up being sanitized and mis-communicated or dismissed altogether.
Not able to succeed at onshore work where being nimble and efficient is key, legacy policies and mentalities from deepwater still override common sense at times - slow and inefficient due to overriding risk-intolerant culture from corporate mining bosses.
Career development is non existent, promotions are made irrespective of skill and talent and based on politicking, networking and ability to present yourself well and talk a good game, if you can tell everybody how good a job you did rather than actually do it yourself you are good. Despite the new policy of only being promoted through applying for posted positions it is still a political game.
