The Police suspected that the helmsman of the "Sveabulk" has fallen asleep on the bridge before the grounding in the Raft Sound.
He was alone on the bridge when the accident occurred.
The "Sveabulk" had held course towards the land, instead of following the fairway.
The mate is subject of investigations in regard of negligence.
When the ship ran aground it suffered a 25 cm long and 1 cm wide gash in the forepeak.
In addition, 20 square meters of shell plating stretching over 4 meters in the keel region were dented. The ship remains at HAMEK for repairs. It was estimated that it would take about a week to repair the ship.
