"Pipeline" Foundations at Petrogal Refinery
Leça da Palmeira, Portugal
Petróleos de Portugal - Petrogal, SA
Petrogal technicians assembled the extremity of the pipeline connecting to the new ocean monobuoy using expansion joints in the pipes, replacing the current solution with flexible curves to absorb the forces caused by the expansion and contraction of the pipes in current operating conditions and/or by thermal variations.
There were designed solid foundation and concrete anchoring to the ground, sized to resist not only these forces, but also the internal pressure of the oil raw, especially in direction changes - special attention was given to the connecting metal parts between the pipes and the foundations, as they are elements of high efforts concentration.
