Shutdown activity is going on which means a lot usage of water for cleaning purposes. In addition to that we have to conduct "Cleaning in Progress" (CIP) for the shell and tube heat exchanger. CIP is carried out to remove the scale and carbon deposited inside the shell and tube in order to improve the heat transfer. Unfortunately, suddenly the water supply was cut off without any notice. Worse than that, nobody realized the unavailability of the water supply for about 3 hours. Upon realizing it, we have to depend on our reserve water supply which is only about 1500 m3. The reserve water is normally saved for the utility boiler because steam is a necessity to run a plant. If steam is not produced with sufficient pressure, production will be affected and if too less, it will stop all plants.
All activity involving water have to be stopped. We have to save the water for the boiler. The plant shutdown cleaning activity was affected and delayed as well. Luckily, the water supplied was back a few hours later and we continued with our shutdown cleaning activities.
