Can Xinxiang crew have two certificates for physical examination?

As far as I know, Xinxiang crew can get two certificates for physical examination. Specifically, the crew's physical examination is divided into two certificates: one is the national ship competency certificate (also known as the maritime competency certificate) and the other is the crew's health certificate (also known as the physical examination certificate). The ship's national certificate of competency is a necessary document for seafarers, which is used to prove that seafarers have the ability to adapt to navigation posts; Seafarers' health certificate is a physical examination report, which is used to prove that seafarers' health status meets the post requirements. Therefore, Xinxiang crew can obtain these two certificates after physical examination. It should be noted that these two certificates are very important in seafarers' recruitment and internship, and their absence may affect seafarers' employment.
