The Minerals Management Service (MMS) mandated that offshore operators in the Gulf of Mexico participate in an annual survey program for the years 2000 and 2005. For 2000, MMS collected information regarding offshore operations. The purpose of the survey was to assist the MMS in constructing an emission inventory for the entire Gulf of Mexico. For the 2000 inventory effort, MMS funded the development of the Gulf wide Offshore Activities Data System(GOADS-2000) software in order to assist offshore operators in complying with the MMS mandate. The GOADS software assists users in recording information regarding emissions-related offshore activities and generates computer data files that can be delivered to the MMS.
