Also, some seafarers may have done their STCW safety courses a long time ago, or, as mentioned above, never done these courses in first place.Yet, techniques and technologies, in particular for firefighting, have evolved tremendously over that period.Which of these certificates the seafarer you will have to update depends on whether you hold a Co Cor not and if so, which Co Cyou hold.A table makes it much easier to understand: The MNTB, MCA and IASST worked together to establish the details for the updating training courses.The same applies to the updating training: From 1st January 2017 you won't be able to sail without documentary evidence of having completed the original training course or the updating training within the last five years regardless of your Co Cbeing in date or not.Also, the updating of the advanced training module does not except the seafarer from updating the basic module.
The good news first: It is relatively painless; updating training consists of very short courses, with the duration never exceeding one day.
The reason for this is that content is widely different.
Take fire fighting for example, where the updating course for the basic course primarily consists of practical exercises on the fire ground whereas updating for the advanced firefighting course consists of mainly theory based updates on new firefighting equipment and techniques.
The best way to think about this is to compare it to the ENG1: When revalidating a Co C, the ENG1 must be in date.
However if the ENG1 runs out shortly thereafter, it will have to be renewed.
It is estimated that we have forgotten 60% of everything we learnt on a safety course after only six months.
