A vessel classed under the IMO DP Equipment Class DP-1 or its equivalent is equipped with a DP system that may fail after a single point failure. The vessel has adequate thrusters and sensors in place for a DP system to monitor and keep the vessel in position and at the same heading for prolong period of time. However, the vessel lacks redundancy and as such a loss of any DP-critical component may render the DP system inoperable.
