The construction of the elevator in question does not meet the fundamental principles for safety integration. There were no safety devices to ensure and verify to the user that the elevator was securely closed and locked prior to lifting.
Comparable equipment with similar flaws provided by other suppliers and manufacturers may be in use on the Norwegian shelf.
