Sometimes it can be difficult to assess the damage caused by weather or corrosion. Digital twins are an emerging technique which creates a high-resolution virtual version of an asset that can be used...
Model-based Predictive Control
Technological developments are breaking down the traditional division between eco-friendly and high-performance industrial lubricants. The developments are being pushed by consumer demand. By Jody...
Lubricants/Greases
Cavitation involves the formation and collapse of micro-bubbles in a liquid, causing erosion and damage to pipework and pump impellers. This article first explores why cavitation occurs and how it...
Impellers
While there is no perfect way to treat large oil spills, a number of techniques have proven effective in mopping up much of them
Pollution Control
Ultrasound is especially good at early detection of bearing faults, lubricant condition, leaks, discharge in electrical systems and steam trap monitoring. Unlike vibration analysis, it generally...

Zinc and chrome coatings have been widely used to protect against corrosion an improve surface properties since the industrial revolution. However, these coatings have historically used hexavalent...
Protective Coatings
Not only are offshore wind turbines a long way from shore, their rotating machinery is housed tens of metres above the surface of the water. The financial incentive to minimise the need to perform...

Jody Muelaner explores how a building management system works and the range of equipment and systems with which it can work
Heating Systems
Operations Engineer explores the basic principles of the reverse engineering technique and how it can be carried out
Plant Refurbishing/Remanufacture
The Covid-19 pandemic has cast human hygiene into the spotlight with repeated messages of ‘wash your hands’. The vital importance of this is clear when it can directly impact on lives, but even at...
