RÉSUMÉ : The oil exploration and production industry in Brazil is highly concentrated in offshore units. The national oil agency states in the 2016 statistical yearbook that national oil production reached 2.4 million barrels/d, 93.4% of which was extracted from sea fields on the previous year. This production concentration in marine units should increase further, with the growing exploitation of pre -salt fields. Thus, the development of decision – making mechanisms to better define supply vessel departure times from ports has considerable importance in ensuring operation efficiency and reliability. This study aims to present and evaluate mixed integer programming models for port berth scheduling. Two problem formulation types are developed and tested on instances. The final proposed model proves to be very useful for realistic applications, reducing the planning time from days to a few hours or, in some cases, seconds.
