Washington ( CNN ) -- The public may have seen the last video images of the failed blowout preventer from the BP oil well disaster , as authorities expressed possible security concerns . The feed from a camera on board a salvage ship was discontinued Saturday after the apparatus was raised from the sea floor and placed on the vessel Q4000 . At his regular briefing with reporters Wednesday , National Incident Commander Thad Allen said additional questions about the unit would now have to go to the U.S. Justice Department and the Joint Investigation Team . When pressed about the video feed , Allen said , `` We 'll have to refer that to the Department of Justice . There were some constraints put on that videotaping based on the people that are looking at the blowout preventer and their identities and so forth , and I think there 's , there may be some security issues associated with it . '' Allen said the ship will carry the unit to shore , but that the timetable and other questions will no longer be something he can address as part of the disaster operations that he heads . As of Wednesday , he said , `` the blowout preventer is already up on deck on the Q4000 . The lower marine riser package has been separated , and they 're putting it on latching skids getting ready to move it closer to shore . '' He said `` exactly when it arrives and what the disposition would be , I would refer you to the Department of Justice , or the Joint Investigation Team , '' since `` from this point out it does n't involve the spill itself . '' Allen said after the ship moves off-scene , `` this will cease to be part of the national response that I 'm coordinating as the national incident commander . ''
The blowout preventer is on a ship in the Gulf of Mexico . A camera feed from the ship was discontinued Saturday . Thad Allen cited security concerns Wednesday on further videotaping of the unit . He referred questions to the Department of Justice .
