  • Simulation of a hub passenger in pre-salt offshore operations


    The Oil and gas operations in deep waters became the main challenge in the production chain studies worldwide. This paper aims to provide a simulation model for the passengers hub transfer to support the pre-salt operations in the Santos basin. The simulation model has been developed taking in account the sea and weather limit conditions for vessels and helicopters operations. The results show that both limitations cause a considered number of interruptions and the level of utilization and size of the hub was determined.


    Operations difficulties in distant oil platforms
    Subject to sea and weather conditions
    Mixed use of maritime and aerial transportation of passengers and goods(Stupalo 2013).
    Objectives of the simulation model
    A Discrete-Event Simulation modeling approach is used with taking account weather and sea conditions, restraining the operations
