Navy gives fresh lease of life to Covid patients


Teams from Visakhapatnam Naval Dockyard achieved a breakthrough in repairing two major oxygen plants in Nellore and Sri Kalahasthi bringing a major boost to the oxygen supply in the state during the ongoing oxygen crisis amid Covid second wave.

Based on a request from the government, the Eastern Naval Command (ENC) airlifted the teams of specialists from Naval Dockyard by naval Dornier Aircraft from Visakhapatnam recently.

The teams successfully repaired the oxygen plants on Sunday by overhauling the compressors and replaced certain adapters and accessories, which were manufactured within Naval Dockyard. The Krishna Teja oxygen plant in Nellore is a big cryogenic plant capable of charging 400 jumbo-type cylinders a day and has been non-functional for the past six years.

The naval team undertook the repairs of the plant and managed to achieve the cryogenic temp of minus 186 degrees Celsius and also achieved the requisite output oxygen pressure to charge bottles.

The analysis of the output is 98 percent oxygen, zero percent carbon monoxide and 0.01 percent carbon dioxide, meeting the requirements of medical-grade oxygen. The oxygen plant at Sri Kalahasthi near Tirupati is a big plant-based on VPSA technology and is capable of generating 16,000 liters per minute at five bar (direct feed to lines rather than charging). The naval team undertook repairs of the plant and achieved the requisite output proved for medical-grade oxygen above 93 percent, zero percent carbon monoxide and 0.02 percent carbon dioxide by carrying out necessary adjustment of column and moisture absorption of the plant.

A specialist team from the Naval Dockyard led by Commander Dipayan worked tirelessly for almost seven days, along with the engineering teams of the Health Department, to complete the task with the cooperation of the Collectors and the administration.
