CLEAR GROUND FOR DETAILED INSPECTION DURING PSC INSPECTION

CLEAR GROUNDS:- Evidence that the ship, its equipment or its crew does not correspond substantially with requirement of relevant convention or that the master or crew members are not familiar with essential shipboard procedures relating to the safety of ship or prevention of pollution.     Clear grounds to conduct a more detailed inspection include:- 1) The absence of principal equipment or arrangements required by convention :- e.g. MARPOL annex 1 requires that ship above 400 GRT and above must have an OWS with automatically stopping device, if effluent exceeds 15 ppm. Absence of this principal equipment will lead to detention. 2) Evidence from a review of the ship's certificate that it is clearly invalid: - e.g. Safety equipment certificate found invalid since no renewal survey was carried out. 3) Evidence that the ship's logs, manuals or other required documentation are not on board, are not maintained or falsely maintained:- e.g. ORB part 1 not present on board or in
