The Norwegian Maritime Authority (NMA) has said that low lubricating oil pressure likely caused engine failure on the cruiseship Viking Sky that led to a dramatic air rescue of nearly 500 passengers.
In preliminary findings, the NMA said that before entering the storm the ship had low lubricating oil levels although within the permitted limits.
When the 48,000-gt Viking Sky (built 2017) hit heavy seas, lubricating oil pumps stopped and alarms were triggered, which shut down the engines while it was off the coast of Norway over the weekend..
