The Sujata operated for 19 years as an offshore patrol vessel but is now used exclusively for training.
The cadets spend six months on the 101-metre-long ship, exposing them to life at sea, shaping their skills on bridge watches, chart work, small arms handling and communications.
The ship arrived complete with its own 11-piece orchestra, which swung into action for an on-board reception last night, playing Indian music as guests from the local diplomatic community, the Royal Thai Navy and others arrived.
Later, the versatile musicians played the music for a karaoke session.
The ship will leave on Monday for the return voyage to India waters.
