Key Messages



A time of unprecedented challenges
Worker force asked to do more with less
Number of expected retirements is
staggering
– Loss of experience and expertise


New, less experienced workers risk
mistakes as they learn
Simulators can help accelerate learning
– Superb training tool, but have been too costly and
complex

New automation technologies bring scalable
simulation within reach

Retirements Bring Challenges
Aging Workforce
How will you capture the wealth of existing
process knowledge to share with new
generations?
Regulations
Will new workers be able to avoid “learning curve”
mistakes that can result in violations, safety issues
and equipment damage?
Abnormal Situations
Is your staff equipped to deal with abnormal events?
How can you help them to prepare?

Growing Trend:
Retirees Are Sometimes Not Replaced





Some authorities plan, as a strategy, to
reduce staff through attrition
Politically less controversial than layoffs
Can result in critical positions being
compromised as positions are combined
Result: Inexperience combined with
reduced focus
Help needed to handle both jobs

Why Haven’t Simulators Been More
Popular?

Expensive – often 10’s of $M
– Typical previous uses in high-risk
environments
– Aircraft training and design
– Nuclear power operations


Complex model software development
Separate equipment required for the
simulator
– Duplicate control room plus simulator
computers
