Low oil pressure combined with heavy weather stopped lubrication oil supply to pumps on the Viking Sky, triggering the shutdown of its engines, the Norwegian Maritime Authority has reported
Low oil pressure combined with heavy weather stopped lubrication oil supply to pumps on the Viking Sky, triggering the shutdown of its engines, the Norwegian Maritime Authority (NMA) has reported.
The cruise ship narrowly avoided disaster off Norway’s coast when its engines failed on Saturday 23 March. Working in collaboration, NMA and class society Lloyd’s Register have initially concluded that the engines were automatically shut down after an alarm indicating low lube oil levels.
Levels were within set limits, although low, when the vessel began to cross Hustadvika - the 10-mile stretch of coastline within which it later lost power. But heavy seas caused movements in the tanks which stopped the supply to the lubricating oil pumps, triggering the alarm.
NMA has drawn up a general safety notice about ensuring a continuous supply of lubricating oil to engines and other critical systems in poor weather conditions. It noted that this should be done in cooperation with the engine supplier and should be included in the ship’s risk assessments in the safety management system.
Viking Ocean Cruises said it had inspected levels on Viking Sky’s five sister ships and was revising procedures to ensure that the issue could not be repeated.
NMA granted the company a permit to sail on a single voyage to Kristiansund last night (26 March) to have repairs made.
“We will continue the constructive dialogue with the classification society, company and the Accident Investigation Board Norway in order to reveal underlying causes and identify appropriate measures,” the administration said in a statement.
