It could take until the end of the week for the issues to be fully resolved after the ferry operator confirmed that nine lube oil pumps have gone wrong in the last 10 weeks.
Condor Ferries chief executive James Fulford said that the pumps on all of the four engines on the firm’s three fast ferries are being replaced with pumps of their own design.
Mr Fulford said they were talking to their supplier about compensation and had not ruled out taking legal action and he apologised for the impact on passengers which means the ferries are running slower.
Over the weekend ferries, including the Condor Rapide on the St Malo route, were running at 25 knots rather than the usual 35 knots.
As a result of the oil pump failures ferries are operating on three engines and Condor Ferries said that examinations and repairs are likely to continue until at least Friday morning (24 May). A spokesman said updates will be provided on the company website and passengers should check sailing times.
â€˜We will provide an update on how this work is going on Wednesday night and in the meantime we would like to apologise for any inconvenience this is causing,â€™ the spokesman added.
As of the latest information on Monday night (May 20) sailings are being rescheduled between St Malo and Jersey as follows; on Tuesday 21 May the 07.00 sailing will leave 15 minutes early at 06.45 and arrive at 07.30 instead of 07.20. From Jersey to St Malo the 16.40 sailing will leave on time but arrive 25 minutes late at 19.25. Similar delays are expected on Wednesday and Thursday.
There have also been problems with jet tube seat ring on the starboard outer main engine on Condor Express which operates between the Channel Islands and the UK mainland. It has a hard wearing section to protect the structure of the vessel and during a routine inspection it was found to have two cracks in it and a failed sealing ring.
Replacement involves the complete removal of the water jet which is currently being undertaken by divers in Weymouth.
