Mariner Energy has been involved in a string of at least 13 offshore accidents since 2006 in Gulf of Mexico waters -- including a blowout and four fires -- that were investigated by the Minerals Management Service (now the Bureau of Ocean Energy Management, Regulation and Enforcement). Possible violations were reported in at least seven of the reported accidents and Mariner has paid at least two separate civil penalties related to accidents, records show.
