During winterisation of the rig the shaker house had to be installed. The first wall segment was lifted by crane in a upright position. Shortly after having parked the wall segment, the upper sliding door (weight 95 kg) moved and dropped out of the rail, fell down from a height of 3,15m and hit the rigger in the neck before it finally dropped on the ground and covered the victim¿s body. Due to the heavy impact, the victim died shortly later, although the rig doctor tried to resuscitate for more than one hour.
