Still the majority of the operational failures are not operated by one aspect only. They tend to be the outcome of minor concerns that are not addressed and accumulated. These problems may begin as small inefficiencies with a bad choice of equipment, missed maintenance, and bad design.
Some of the operational decisions may appear sound and prove evidently harmful with time as the number of safety accidents and quality malfunctions increases. To ensure your business is profitable and running, it is necessary to know how to identify the root of these failures.
Equipment standardization and material choice matter
Table of Contents
The most frequent operational blind spot particularly in manufacturing set up is the inconsistent equipment specification across plants or manufacturing lines. Reliability decreases whenever there are multiple processes in which there is a dependency on a variety of materials and standards. This is particularly in systems that deal with fluids which may have the chance of corrosion and contamination. You have no desire to have some of your systems optimized fully, yet the others are sub-standard. Standardizing all systems around durable components – like stainless steel centrifugal pumps for highly corrosive applications – will reduce downtime and extend the life of every system.
Purchasing on the basis of reducing costs in the short run or by what is accessible at the moment will result in integrating incompatible materials, which will hasten the corrosion and contamination. To illustrate, the stainless steel centrifugal pumps are usually used in industrial conditions as it offers high degree of resistance against corrosion, thermal stability, and cleaning is also simple as compared to carbon steel pumps or plastic pumps. When you purchase a cheap pump and you are trying to save money, you will compensate the money by experiencing a shorter life cycle and failure in the middle of the way.
Standardization needs to be ensured, which means breaking down the operating silos and ensuring that each purchase is planned with long-term viability. The outcome is fewer maintenance requirements, steady production and reduced downtime.
Never defer maintenance to support production
Deferred maintenance is a form of costliest and most devastating operational practice in the industrial plants. By cutting the maintenance process to produce more, you risk more failures of the equipment. The approach to maintenance, where maintenance is treated as optional, may have a domino effect of failures that may get into a complete failure.
The best maintenance plans are preventive and predictive. Reactive maintenance to address failures may be up to three times more expensive taking into consideration the cost of emergency repairs, overtime work, equipment downtime, and lost profits.
Proper maintenance can be achieved by starting with the use of the routine check and frequent lubrication which might delay the process in case the production is at the peak. Failure to observe inspections and maintenance programs and schedules may lead to faster wears and rips in bearings and seals and damage rotating elements in pumping and compressing machines. When it cannot be stopped to carry out some maintenance, then it is worth investing in the acquisition of secondary backup equipment that will be able to take over the tasks whilst the primary equipment is being serviced.
Don’t underestimate energy inefficiencies
Consumption of energy is a manageable cost however the inefficiency is not easily visible without sensors placed on the equipment. You have to have a sensor to inform you when equipment is being inefficient. But what the sensors do not say. You must also take into considerations the following:
- Mismatched or oversized equipment. Not buying the right-sized pumps and motors intentionally is what companies will usually do, which leads to inefficiency. To contain electricity consumption, it is also important to properly adjust the size of mechanical parts.
- Lack of variable speed controls. Fixed-speed equipment compels systems to go full blast when they are not needed. Variable frequency drive items can be used to minimize energy usage by adjusting output to the needs of the process at any change.
- Aging systems. The equipment in use has a tendency to become ineffective with age. This is why it is necessary to test and maintain regularly.
Alarms will not be rung by every source of inefficient energy, but it always costs profits.
Remember to consider failure when designing systems
In case the industrial processes are developed with respect to the optimal operating conditions, then they fail to consider the behaviour of the systems under loads or systems that fail. These potentials should be tackled when designing the system, no matter how insignificant the small issues are, they can magnify themselves. As an example, systems must have redundancy to minimise the possibility of a complete shutdown in case of failure of one of the components. It is also important to make systems easy to service so as to make the time of repairing the systems to be safe and reasonable.
The equipment will also require repairs here and there and that is the reason why systems have to have isolation valves and bypass loops. As a result, you will have to do a complete system shutdown on the smallest of repair orders. Disruption planning systems help to make them more robust.
Manage operational risk early
Quite several decisions appear rational individually, but when implemented in industrial systems, they become hazardous. Each decision is important, including components and service, design and materials. It is possible to avoid weak points, minimise the downtime and make operations stable even in case conditions are not perfect by making the correct decisions at the beginning.
