Abstract
The Bremen Cog from AD 1380 is one of the world’s largest ship finds. It is 23.27 m long, 7.62 m wide, and 7.02 m high to the top of the capstan on the castle deck. Its conservation took 19 years. A specially developed two-step PEG-treatment was employed to an extraordinary scale; the conservation tank held 800 m3 PEG-solution. The stabilization of the once-waterlogged timbers is good, residual shrinkages average 2.3%, corresponding to an anti-shrinkage-efficiency (ASE) of 84%. The novel conservation method was a success, and the concept of rebuilding the ship before conservation proved to be valid. -- SCMRE
