Powers to inspect
8.—(1)  A ship to which these Regulations apply shall be subject in Singapore waters, to inspection by a surveyor of ships. Any such inspection shall be limited to verifying that there is on board in relation to that ship a valid Certificate referred to in regulation 11 or 12A of Annex II or a valid SNLS Certificate unless there are clear grounds for believing that the condition of the ship or its equipment does not correspond substantially with the particulars of that Certificate. In that case, or if the ship does not carry a valid Certificate, the surveyor of ships shall take such steps as he may consider necessary to ensure that the ship shall not sail until it can proceed to sea without presenting an unreasonable threat of harm to the marine environment. The Director may in such a case permit the ship to proceed to the nearest appropriate repair yard.
(2)  Upon receiving evidence that a particular ship has discharged noxious liquid substances or unassessed liquid substances carried in bulk or a mixture containing such substances contrary to the provisions of these Regulations, the Director shall cause the matter to be investigated by an inspector and shall inform the State which has reported the contravention as well as IMO of the action taken.
(3)  The Director may also cause a ship other than a Singapore ship to be inspected by an inspector when it enters Singapore waters if a request for an investigation is received from any State which is a Party to the Convention together with sufficient evidence that the ship has discharged noxious liquid substances or unassessed liquid substances carried in bulk or a mixture containing such substances in any place. The report of such investigation may be sent to the State requesting the investigation and the State in which the ship is registered.
