Modifications to Burner Boom Structure of Rig Hercules 31- M/S Cairn Energy India Pvt Ltd
This work was undertaken during the year 2007 and involved complete modification to jack house structure of the rig Hecules H-31. As the work was required to be undertaken while the rig was in operation, complete safety and utmost care during the work for the structure and the men had to be ensured. The complete modification to the structure included strengthening of the jack house and modification to the burner boom. The burner boom which was damaged was shifted on shore to jetty,
where the complete structure of the burner boom was renovated and the heavy machining for bushes made of Gun metal and En steels for the pins of 200mm dia and 350mm dia was undertaken in our machine shop. The support brackets for the booms were fabricated and welded to the burner boom support structure. New walk way was also fabricated for the booms. The fabrication of Approx 40 tons of Steel was carried out with Third Party certification of RT and MPI. On completion of the modification, the complete burner boom was load tested up to 22 tons with SWL of 11 Tons.
