The DCU heater having tripped put the entire plant into a tizzy. Firstly having to ascertain the root cause and finally the solution.
We were called to help out. A supervisor along with the director flew out to Assam to assist. We recommended the bottom tubes be opened and inspected. There were blocked. Options were a plenty to clean the same but time was short. On rummaging through the plants resources we found a high pressure machine with some lances.

Change of catalyst and gasket in reduction zone in platformer after a minor fire.
A minor fire in the reduction zone of the platformer brought the PX plant to a grinding halt. M/s Koins were once again called to help out. Time was of the essence, catalyst had to be unloaded under nitrogen, man entry had to be done under inert conditions to open the transfer pipes and the reduction zone had to be lifted for change of gasket which had given way. Non availability of large crane at such short notice, forced us into improvising a kind of chain block arrangement for the massive left using safety certified lifting jigs. The end result a 100% safe job bringing a smile to the face of plant personnel. |

Cleaning of product Lines upto loading Arm
The terminal was faced with a peculiar problem, of wanting to clean their product lines in the jetty area leading upto the loading arm. The lines were of 32" in diameter and over 500 meters long. Already being in service a cut was ruled out and conventional pigging was difficult as there was no outlet for retrieval of pig.
A combination of specially designed squeezy pigs from Korea with rotoflush technology proved successful with a repeat order for other lines.
