After the implementation of the rule 1 1, make-up shift of the unit will be carried out. For ordinary crew members, they only need to attend basic safety makeup training, and for senior crew members, they also need to attend makeup training with certificates of competency. If your fourth certificate says b0 1, you need to take a make-up exam.

B0 1 will be changed to z0 1 after the new version of the four small certificates is reissued. Require makeup training for seafarers (no personal participation). If you have six months' sailing experience before 20 120 10 1, you can directly renew z07z08 to 20 140 108.
