On May Day, the workers worked overtime and stuck to their posts to carry out maintenance work on the German heavy-lift ship Frauke. Frauke's new ballast water treatment system had many problems, including unclear electrical drawings and numerous maintenance items, which made the construction difficult and the overall maintenance time difficult to control. The engineering department communicated with the shipowner many times to analyze the problems and difficulties, and after the joint efforts of the workers, the Frauke heavy lift ship was officially completed and left the factory on May 11, 2023.
