Is this assessment or design?

Is this assessment or design?

Away from a collision course
Equipment integrity design and assessment methods are not only linked to different life stages. These methods are essentially different in their concepts. A strange mixture of design and assessment data can be observed in engineering reports where this difference is misunderstood. Let's consider some logic for engineering analysis tools selection from the decisions' confidence standpoint. The engineering 'Reality' I would describe the purpose of engineering activities as understanding and addressing the Reality for a continued safe operation of the equipment. Reality here is the equipment actual load bearing capacity in the environment of real operational loads and damage processes. This is a key element of the design Quality. Otherwise, not controlling the equipment integrity will always cancel cost/benefit aspirations and aesthetic emotions. Let's make a short departure towards the Quality…

Failure Probability vs Failure Frequency

Failure Probability vs Failure Frequency

Away from a collision course
Probability of Failure (PoF) is relevant to individual equipment units and is a function of time. Failure frequency is relevant to a population of generic units, and is averaged over a time span. Which level of consideration should we use? It depends on the context and, mainly, on our goals. Let's drill this option down from rocket science to engineering practice. There were 85 orbital launches in 2016 (refer this page). Two of them failed. The failure frequency is 2 / 85 ≈ 0.024. But does this tell us if the pictured rocket will reach the orbit? No, it doesn't. The failure frequency tells us what is the chance of reaching the orbit in any contemporary rocket, subject to the nowadays technical and managerial environment, if nothing changes. If any…

Is it possible to become 100% compliant and what for?

Is it possible to become 100% compliant and what for?

Away from a collision course
As we spoke in our 12/09/2017 post, the oil and gas immediate savings motive has a potential for safety issues.  Here we will discuss the safety compliance options, and will outline an umbrella against major incidents and their implications. We start from a brief of the Australian Health and Safety legislation (if you are within, familiarizing with the below references is highly recommended). It could also be consistent with other countries safety management main principles - please check your local health and safety (H&S) legislation. The Australian top level enforceable safety law is the Workplace Health and Safety Act (WHS Act, 2011), which is the legal framework for penalty decisions. It is supplemented by WHS Regulations, which are State specific, but all follow the same base model with minor changes…

Savings on staff explained in numbers

Savings on staff explained in numbers

Away from a collision course
Is your organization changing its staffing plan? Is there a voice that taking more graduates on board will be beneficial? Does it look like seniors (expensive and hardly manageable) are replaced by juniors (freshly thinking and self motivated)? This topic is coming up every noun again, and we decided to examine it in numbers from an organization capability standpoint. Assume a virtual engineering company which has 5 seniors and 5 juniors. This team currently does 100% of the monthly work and makes a gross monthly revenue of $150K average. The salary fund is 1/3 of this number and the seniors are paid twice more than juniors, thus we have the equation  5*2*x + 5*x = $50K, where from a junior gross salary is $3.300, and a senior is getting $6.600…
