JUDGMENT
1 HIS HONOUR: In November 2002, the owner, master and chief engineer of the 42.7 metre twin screw vessel "Seahorse Horizon" were, respectively, Defence Maritime Services Pty Ltd, Mr Allen Coates and Mr Danny Mahon. Each has pleaded guilty to a charge of polluting the waters of Sydney Harbour on 5 November 2002. The charges against the owner and master are under s 8 of the Marine Pollution Act 1987. The charge against the chief engineer is under s 8A. This judgment is concerned with penalty in relation to the owner and master only. Penalty in relation to the chief engineer is the subject of a separate judgment. The evidence against each defendant is not identical. For example, the evidence of the chief engineer is not in evidence against the owner and master, and the evidence of the master is not in evidence against the chief engineer. The prosecution's evidence in chief against all three was presented at one hearing, after which the evidence for the owner and master and the evidence for the chief engineer were heard separately.
2 The owner pleaded guilty to a charge that on 5 November 2002 it was the owner, and the master pleaded guilty to a charge that on that day he was the master:
…of a ship named Seahorse Horizon from which a discharge of oil occurred into State waters namely the waters of Sydney Harbour, in contravention of Section 8 of the Marine Pollution Act 1987.
3 Section 8(1) of the Marine Pollution Act 1987 provides:
(1) Subject to subsections (2) and (4), if any discharge of oil or of an oily mixture occurs from a ship into State waters, the master and the owner of the ship are each guilty of an offence punishable, upon conviction, by a fine not exceeding:
(a) if the offender is a natural person - $500 000, or
(b) if the offender is a body corporate - $10 000 000.
4 The movement of the vessel on the day in question may be briefly described as follows, although it will be necessary later to go into more detail. At 0845 hours the vessel was un-slipped from Goat Island and various trials were carried out within Sydney Harbour when an overheating problem in the port shaft and a drop in the port header tank were observed. At 1000 hours the vessel was docked at Garden Island where a problem was detected. At 1053 hours the vessel left for Goat Island for the purpose of slipping it there in order to investigate the problem. The vessel stood at the approaches to the slip at Goat Island for a time. However, due to the congestion at the slipway and a falling tide it could not be slipped at that time. The vessel therefore proceeded to the naval establishment HMAS Waterhen at Balls Head Bay, where it was secured at 1140 hours and an oil containment boom was placed around the vessel.
