MS Estonia, 2021 Investigation, ROV's 3rd dive

As per the procurement of Estonian Safety Investigation Bureau, ROV surveys were conducted at the wrecksite of m/s Estonia on 14th and 15th of July 2021. The goal was to verify objects and images found with the sonar survey. Out of the seven dives made, the third one was made by the drone to observe the condition of the mudline as closely as possible across the entire starboard side of the wreck, including the narrow recess between the hull and seabed.
