HUET is not as universal as you make think..... or wish. There are 45,000 offshore workers in the Campos Basin, Brazil, whose (Petrobras) employers have been persuaded NOT to introduce HUET. I am not exactly sure who has persuaded who but it is not been mandated and it is a regrettable lapse.
There is a first class HUET training facility in Macae but, alas it was just ticking over last time I was there.
