A V.Group-managed tanker was holed in a grounding off western Scotland last year after crew ignored the electronic chart system that showed a big rock in the way.

An investigation by the UK's Marine Accident Investigation Branch (MAIB) found that the bridge team on the 3,500-dwt Key Bora (built 2006), owned by Key Shipping, preferred locally produced survey data that did not include the obstruction.

This was the second investigation involving the ship, following a jetty crash in 2013.
