Thomson Cruises said a lifeboat accident that killed five crew members onboard one its ships occurred when a cable snapped as the lifeboat was being raised back up to the ship after a routine safety drill. Eight crew members were on the lifeboat when it fell back into the water and overturned. Three crew members also were injured but have been discharged from the hospital.

The accident happened on the Thomson Majesty, which is owned and managed by Louis Cruises, on Feb. 10 in La Palma, Canary Islands. Thomson said it was waiting to hear from investigating authorities when the ship could resume the cruise. A passenger named John Bulpin posted on Facebook that he was on the ship and heard that the captain was “contemplating continuing the cruise” without one or two lifeboats.

A Thomson representative responded to the Facebook post: “Passengers that were assigned to the lifeboat that is now out of action have been re-assigned to other boats, and will take part in a drill to ensure they are aware of the new procedures. The second lifeboat you mention remains fully functionally but will not be used due to maritime law stating that we must have symmetrical boats. We have more than enough lifeboat and life-raft capacity for all on board, should they be needed, and all of the lifeboats and their launching apparatus are in the process of being checked by ship’s staff and by investigators. We will not sail unless the investigators confirm that they are safe. Should you have any queries, or need any assistance whilst on board, please speak to our team on board who will do their best to help.”

Thomson said it was working closely with Louis Cruises to determine exactly what happened and provide assistance to those affected by the incident. The company said it was working closely with the authorities and is cooperating with their investigations.
