Justice R Subbaiah adjourned to February 26 the petition filed by B Viyaya Bharathi wife of Bhavani Shankar seeking a high-level inquiry into the death of her husband and the co-worker and compensation.
Shankar and Mahendran died while four others took ill on January 27 after inhaling "poisonous" gas when they opened a manhole on the deck while undertaking welding work for towing the submarine.
Petitioner said her husband was the only breadwinner for their family and sought adequate compensation.
