If, after receipt of the information in the last answer, there are clear grounds for believing that the ship is not in compliance with the ISPS Code, it is likely that port State control officers will attempt to establish communication with the ship and the flag State Administration (i. e. MCA) in order to rectify the situation.
Should this fail, they may take proportionate steps including: (1) a requirement to rectify the non-compliance; (2) detention of the ship; (3) a requirement that the ship proceeds to a location specified in the State’s territorial seas or internal waters; (4) inspection of the ship if it is within the territorial sea; or (5) detention of the ship and/or denial of entry into port.
