You drew the boundary in such a way that the cylinder-actuator belongs to the hydraulic system and not to the valve. That is perfectly legitimate. You can draw the boundaries in any way that you…

A common cause failure has the same failure mode in common with another failure elsewhere in the hierarchy tree view of the RCM knowledge base. Their appear to be four seemingly similar cases that need to be distinguished, but only case 2 describes a common…

In your living RCM offering do you provide models or templates for systems and components typical to the oil and gas industry? The short answer is yes. Generic templates may be used subject to the following cautionary note. A pre-packaged FMEA or RCM analysis can contribute to the process as do other forms of technical…

The facilitator must guide the analysts along a path…
