The aircraft is likely to be a Changhe Z-8, a Chinese copy of the SA 321 Super Frelon, according to an earlier press release by the ministry.
It had to make a force landing aboard the ship and was on fire, the deputy commanding officer of the vessel made a decision to push the aircraft off the deck after he discovered fuel was leaking while putting out the fire.
