It is difficult and expensive to do vessel-specific training well. This is probably why, unlike certification training, it is under specified, and in many cases poorly implemented - often via job shadowing. But there is a technology which is an excellent tool for vessel-specific training, and every vessel operator should be aware of it. It is called adaptive learning. This article describes adaptive learning and examines one vessel operator’s deployment of it in order to facilitate vessel-specific training across its fleet of 35 vessels.
