Hello, dear, I'm glad to answer your question: what are the four certificates of the crew? Where can I do it? The answer is: honey, you can go to the local maritime bureau to apply for the four certificates of seafarers. Before entering the exam, you need to go to a designated institution recognized by the Maritime Safety Administration for full-time study for about 40 days, and then you can take the corresponding exam. You can review with the help of the school seafarers' four certificates APP. After passing the examination, you can bring your ID card, physical examination certificate and other relevant documents and materials to apply for four certificates of crew. The "four small certificates" are the most basic documents for boarding the ship, and they shall be handled at the Fisheries Technical Training Center of the unit directly under the Municipal Ocean and Fisheries Bureau. Specifically: familiarity and basic safety training certificate, proficiency in survival craft and rescue boat training certificate, advanced fire protection training certificate, proficiency in first aid training certificate, advanced medical training certificate, ship security officer training certificate, safety awareness training certificate, crew training certificate with safety responsibility, etc. After passing the training of four certificates, you should know the relevant skills of ship rescue, fire fighting, first aid and raft operation. However, only four certificates can't be employed on the ship, and (the personnel of the Ministry of Affairs can, such as cooks and waiters) must also have certificates of competency for corresponding positions, such as mechanic's certificate, sailor's certificate, driver's certificate and engineer's certificate.
