Analysis of offshore transportation logistics by discrete-event simulation

Abstract

Logistics plays a fundamental role in the petroleum and oil industry, since large distances between offshore units and its onshore supply base demand an efficient supply chain. In this scenario, oil companies use huge infrastructure to service, maintain and develop operations of offshore units, composed by airports, ports, hubs, warehouses, specialized vessels, among other resources. Weather conditions, vessels off-hire rates and vessel waiting time to operate offshore units are the more sensitive variables that affect offshore supply operations. In this context, the present work aims to find the ideal amount of supply vessels necessary for the logistics of offshore cargo transportation to fulfill its function without affecting the service level demanded. In this study, resource cost perspective will be incorporated for analysis purposes.
