In the morning of Aug 18 attempts were being made to correct the list of the floating dock Nordsøkedralen with the 'Hardhaus' inside at the Hirtshals Yard AS by shifting the water in the dock's ballast tanks. If it does not succeed, a very large crane will be needed It remained unclear what caused the accident, but one man in the covered dock remarked a big bang at 6.15 a.m. The man hurried out of the dock, and shortly afterwards, it partially broke down on the side. The employees usually start at 7 a.m. so it was fortunate that the accident occurred at the time it did. On Aug 17 the yard's management held meetings with experts and representatives of the insurance company all day long to make a plan for how the dock could be rectified with least damage. Divers were sent into the dock in the night.
