Two fishermen were killed and four others went missing after the ship 'ICGS Vaibhav' collided with their fishing trawler 'Sea Messiah' off south Goa-Karwar coast.
The Coast Guard has ordered a Board of Inquiry into the matter against the Commanding Officer of the rank of DIG and other crew on board the vessel, sources told PTI here.
The brand new ship was on a sea sortie and is yet to be commissioned into the force.
The "carelessness" of the ship's crew would also be looked into by BoI headed by a senior DIG of the maritime force, they said.
Earlier, there was a confusion on whether the ship belonged to the Navy or the Coast Guard, but it later emerged that it belonged to the Coast Guard.
The vessel built by the Goa Shipyard Limited was to be formally commissioned by Defence Minister A K Antony on May 11 but it is learnt that the Coast Guard function is likely to be cancelled, Navy officials from Goa said.
