Can Nanyang Maritime Safety Administration handle the crew service book?

Yes, you can. According to "People's Republic of China (PRC) Crew Law" and "People's Republic of China (PRC) Crew Service Book Management Regulations", Nanyang Maritime Bureau, as an institution with ship registration and maritime management functions, can handle the crew service book. The crew service book is an important document to prove the identity of the crew and the maritime work record, which records the personal information of the crew, the historical work of the ship and the certificates held. If you need to apply for a crew service book, I suggest you go to Nanyang Maritime Safety Administration to consult the specific procedures and requirements.
