Knowledge decay is a real problem for any worker in any industry. Where safety is absolutely essential, we want to ensure that any training sticks. The widely accepted hashtag#Thalheimer and hashtag#Ebbinghaus learning & forgetting curves demonstrate that forgetting is significant within hours after completion of initial training. To combat this natural phenomenon, training cannot be an isolated, one-time event. That's why IADC is developing its K.R.E.W. training program to meet the demands of the industry for our people in the field.

This concept is applied in Aviation for decades, on refreshing Simulators training for Pilots, every six months, based on the premise that after this period, even if you have good memory, you would remember 20% max.

For Semi-submersibles, the Ballast Control & Stability refreshing courses are every two years, due the costs of physical units. We aim to break this paradigm delivering advanced eTraining technology on cloud platforms.

Alex The 2 yearly refreshers are a recommendation only (non binding) and most companies ignore it. Unless it's in the safety case or a class/ flag requirement then it's almost impossible to get training approved/ supported. I agree that (lack of) retention of knowledge is of concern but unfortunately it gets little focus from companies unless it's highlighted by an audit or, worse, an incident investigation. This is despite many a BCO or Barge highlighting the issue to management.

I believe your approach provides a practical solution to address the loss of stability response capability and hope that flag/ class will drive it's adoption throughout industry.
