to the next level , by using tech to help drive something called “ prescriptive maintenance ”.
He says : “ Imagine you have two identical assets . One ' s nicely tucked inside a factory and so is in a fairly constant environment , but the other asset is exposed to the elements on the seafront . Clearly , you ’ re going to have different performances from those two assets , and so you create prescriptive maintenance cycles that take environmental conditions into account . It ' s an individualised maintenance strategy .”
The energy and chemical sectors use prescriptive maintenance tech most heavily , because of the vast environmental differences in which they operate .
Having fine-tuned maintenance cycles - whether predictive or prescriptive - is important for preventing over-maintenance as much as under-maintenance , Hancock stresses .
“ If you ' re over-maintaining an asset you ’ re wasting money and resources . Why do an overhaul every six month when it ’ s not necessary ? With predictive maintenance , you can use historical information via IoT sensor data and extend the maintenance cycle to seven or eight months , with no negative impact on the machinery .”
This is why predictive maintenance has huge sustainability benefits , because assets cost less to run over their lifetime . Also ,
