pusher-barge combination ''Herakles-Bulk'' sank near the Grundkallen lighthouse. The combination had left Oxelösund two days earlier and was heading north with the barge fully laden with coal. On 2 March she ran into a storm and the captain, not certain if the vessel could be safely turned around in such conditions to seek shelter closer to the coast, decided to evacuate half of the crew by helicopter. When the port engine began overheating and later the starboard engine lost all power, the combination was no longer able to keep the bow into the wind and began to drift uncontrollably in the storm. The remaining crew was soon evacuated and shortly afterwards ''Herakles-Bulk'' collided with the lighthouse, causing superficial damage, and foundered in the nearby shallows.Työntöproomuyhdistelmä HERAKLES-BULK, vaaratilanne ja uppoaminen Selkämerellä 2.–3.3.2004

The 159-metre barge broke in two and an approximately 95 metres long section settled in the bottom on an even keel only tens of metres from the lighthouse. Part of the side structure and a ramp protrude above the surface. Another section, approximately 60 metres long, is located about 300 metres south-southeast from the lighthouse, with the forecastle of the barge protruding in an oblique angle above the surface.Swedish Maritime Administration
