Industry giants with the likes of Shell, Exxon, BP, Total and any major players for that matter, have rules and standard set in place dedicated to one subject area called Energy Isolation. Energy source could be in various form such as electrical, heat or pressure energy. Different companies and state agencies will have varying regulations and engineering practices for system or equipment isolation during maintenance and intervention. Nevertheless, regardless how minor or how critical the isolation requirement, the objective is to always meet the minimum “safety requirements”.
