Alteração da topologia de rede Controlnet™ para Ethernet/IP™ para a estação de controle mestre de um sistema de produção submarino

Abstract

This study proposes the change of the network topology of the master control station in a production system comprising subsea equipment controlled in the topside, in a floating production, storage and offloading unit. It also provides an overview of a subsea production system, from its conception to the control systems detailing; besides the overview of industrial networks, comparing communication protocols, particularly the ones subjected to the proposed change, the current used ControlNetTM and the Ethernet/IPTM. The reason behind this proposal resides in the fact of the industrial platforms to be migrating for a more integrated and standardized solution, the Ethernet standard and to avoid both technological and marketing obsolescence, it is proposed such change in the master control station. As results, it is presented the feasibility study of the change, the required engineering detailing as well as a test bench implementation that will serve to validate the results, in future studies, with a methodology based on the network data transfer, communication failure rate and bit error rate to validate the robustness and reliability of the proposed solution.
