Last year there were several safety deficiencies on the ship.
The captain of the cargo ship Solong, who collided with a tanker on Monday, is a Russian citizen, says a shipping company.
British police have arrested the captain on suspicion of gross negligence.
However, the captain, at least for the time being, is not suspected of intentionally causing the Haver.
The crew of the Solong ship, which was littered to Portugal, consisted of Russians and Filipino.
The investigation of the case has revealed that the ship had security checks in July in Dublin, Ireland and in October in Scotland.
Both inspections showed safety deficiencies, but the ship was allowed to continue.
