After the third replica of the Bremen cog from 1380, the "Roland von Bremen" sank in the morning hours of January 28, 2014 at its berth at the Bremer Schlachte, the cog was launched again on March 20, 2021 after extensive renovation work.
The floating cranes "SK 1" and "Athlet" from BVT Chartering and Logistics GmbH performed the job, which was not an everyday job due to the design of the ship, routinely and reliably to the relief of those present.
