During a voyage from Visby to Oskarshamn, the vessel ATLANTIC ran aground just south of Oskarshamn. The master, who was alone on the bridge at the time and had the Bridge Navigational Watch Alarm System (BNWAS) turned off, has stated that he fell asleep just after he made the turn north of Öland towards Oskarshamn. The information is supported by the vessel’s AIS track, which shows that no course corrections were made following the turn.
