Automatic identification system (AIS) data has revealed that the 1,922-teu containership Delphis Gdansk (built 2017) was forced to avoid an oncoming ship shortly before it was involved in a collision with the 37,506-dwt bulker BBC Neptune (built 2010) off Denmark last week.

AIS data showing the movements of all three vessels in the moments before the crash is sure to play a critical role in the safety probe into the casualty being conducted by the Danish Maritime Accident Investigation Branch.
