Port chiefs at Milford Haven are to be pros-ecuted over their handling of the Sea Empress oil spill disaster, it was announced yesterday.

The criminal charges were announced by the Environment Agency, shortly before publication of an official disaster report detailing numerous mistakes made in the February 1996 disaster.

The report blamed the initial grounding of the 147,000-tonne vessel on the inexperience of pilot John Pearn, who was guiding her into port.

However, it was errors after that which caused the second grounding of the ship and the spilling of 71,800 tonnes of oil the Marine Accident Investigation Branch said.

The Environment Agency charges have been brought against the Milford Haven Port Authority and the port's harbourmaster Mark Clive Andrews.

The case is expected to be heard at Crown Court, and, if proved, maximum penalties could run to #1m or two years' imprisonment.

The MAIB official report concluded:

q Some non-essential personnel were, riskily, allowed on board during the early stages of the salvage operation;

q The operation took as long as it did (six days) because there were insufficient tugs of the appropriate power and manoeuvrability;

q There was also a lack of full understanding of the tidal currents in the area;

q The onshore management team became too large and unwieldy to cope with a rapidly moving salvage incident;

q The principal responsibilities of some persons within the com- mand/control organisation ashore for dealing with the salvage operation ''were not clearly defined and this led to some confusion;''

q The Marine Pollution Control Unit's national contingency plan was deficient.

q The whole salvage incident would have been better managed by a small command team, acting as a single unit, with a clear leader and fully operational on a 24-hour basis.

q The oil pollution would probably have been avoided in the initial grounding if the Sea Empress had been constructed to the double hull design.
