Abstract
The disaster concerning the "Deepwater Horizon" platform at the Gulf of Mexico in 2010 raised the discussion on the efficiency of the safety systems employed on offshore well, more specifically Shear Ram BOP (Blow Out Preventer) - SRBOP, or BOPs of shear Rams. The use of such equipment is the last resort, in cases of extreme risks, in order to maintain the environmental and material safety of a marine platform, when there is a "Blowout" or "well kick" – which are abrupt eruptions of gases and oil in high pressures and temperature conditions. The function of the SRBOP is to cut the production or the drilling pipe, allowing a safety seal of the well. Then. After this accident, it was estimated a high increase in insurance costs for equipment and facilities of offshore explorations, being 50% for deepwater wells. These new rules affect directly the Brazilian Pre-Salt operations. Thus, this work aims to study the shear force estimation of an SRBOP using the Finite Element Method (FEM) with element-deletion algorithms, considering a material failure criterion known in the current literature.
