Investigation report into marine accident including what happened, safety lessons and actions taken:
MAIB investigation report 18-2018: Celtic Spirit

During the morning of 1 March 2018, the UK registered general cargo vessel Celtic Spirit started to drag its anchor in heavy weather on the River Humber, UK

The watchkeeper did not immediately identify this and Celtic Spirit subsequently collided with the research and survey vessel Atlantic Explorer and the general cargo vessel Celtic Warrior, which were at anchor.

All three vessels sustained shell plate damage, but there were no injuries and no pollution.

The report highlights the importance of ensuring taking tidal and environmental conditions fully into account when going to anchor and ensuring that the frequency and accuracy of position monitoring is commensurate with the conditions experienced.
