The cruise ship Viking Sky with 1373 passengers and crew aboard narrowly escaped a major accident on 23 March 2019, when her engines failed during a severe storm. The ship drifted rapidly toward the coast of mid‐Norway in very rough waters, but was finally saved by the anchors less than 100m from land. All engines tripped almost at the same time because of a low‐level signal from the level transmitters in the lubrication oil tanks. This system is installed to protect the engines from being destroyed if the lubrication is lost. The level of oil was not critically low, but the heavy seas probably caused movements in the tanks that fooled the level transmitters. The (preventive) shutdown of the engines was therefore a typical systematic fault, caused by a specification or design error of the lubrication oil tanks and/or the placement of the level transmitters. If not modified, the same engine shutdown will reoccur the next time the ship meets the same weather conditions.
