Summary
Investigation of Saffier’s contact with an unmanned berthed tug at Immingham following excessive astern propeller pitch. Incorrect feedback calibration escaped post-repair testing, while unfamiliarity with backup controls and delayed emergency action worsened the event. Recommendations address full-range propulsion checks, emergency drills and clearer backup-control identification.
