A large public sector oil refinery in Maharashtra faced 33 breakdowns in the first year and a half of its operations. The problem was pinpointed to the failure of the seals and couplings. Despite constant repairs, they kept malfunctioning. That is when Environics was called in. We found that all the couplings which were in a single line were cut by Hartmann Lines. We carried out the necessary corrections. Post correction reviews showed that the incidence of shutdowns had tapered off. Thereafter we were assigned further correction projects in other plants by this PSU.
