Blowout Preventers, BOPs, are essential safety equipment for oil & gas industry. Nevertheless, Brazil does not have a manufacturer that can provide this equipment and the Brazilian National O&G agency regulator has been pushing for O&G explorer and producers to use a minimum of machinery from local suppliers. With this regulatory demand, a BOP was developed from scratch. International Standards have been evaluated to understand what could be adapted as no standard is applied specifically to this equipment. Analytic and numerical simulations were performed and adjusted according to local suppliers’ limitations for materials and testing. Tree prototypes were built and tested to evaluate the design and functionality of the BOPs. At the end, the design was proven to work and the prototypes are being tested for long time without presenting any problems. This project was supported by an innovation agency EMBRAPII and was developed by SENAI CIMATEC to PERBRAS Company.
