Regular infrared inspections can help keep systems running safely, efficiently

21/01/2021 By Siemens

Infrared cameras are ideal for finding apparent temperature differences between components or materials that can point to a potential problem. Whether you’re looking for hot or cold spots or the apparent surface temperature of a component or target area, using infrared cameras with advanced focus systems, IR-Fusion technology, color alarms, and user-defined spot markers help you find problems fast.

How to measure output voltage from a VFD to a motor

21/01/2021 By Siemens

Learn the step-by-step measurement sequence for assessing output factors of a variable frequency drive when troubleshooting electrical signals

Learn the 5 steps to measuring output voltage when troubleshooting VFD problems

When troubleshooting the electrical signals within a motor/drive system, think in terms of input vs. output. A variable frequency drive (VFD) transforms the input mains of constant voltage and frequency into a voltage and frequency range that can be varied to control motor torque. Troubleshooting at the input starts with testing power and supply.

Automation for Oil and Gas

22/07/2014 By Siemens

Brutal competition

Today’s oil and gas sector is facing brutal competition for an increasingly limited resource so engineers can no longer rely on experience and gut feeling when drilling. Furthermore, getting things wrong can be very expensive.

It is well known that downtime in oil extraction is amongst the most expensive in any industry, with one hour costing up to $1 million in lost revenue, fines and maintenance activities. What’s more, the associated safety, environmental and reputation concerns also add to that cost.

Furthermore, oil companies come under extreme scrutiny from regulators, their communities and environmental observers. One way to ensure minimal downtime and zero accidents is to analyze big data.

Petroleum and gas exploration are real-time activities and engineers need “as you drill” information to make the right decision. Site operators need to know whether they are going in the right direction, whether to drill horizontally, vertically or stop altogether.

And this is a difficult undertaking. Everything noteworthy happens underground, miles inside the earth’s crust. Or, if you are lucky to be working on a sea rig or platform—braving the fury of the elements—additional environmental factors need to be taken into account.

Gathering data is crucial for scheduling maintenance activities. It allows site managers to anticipate malfunctions and pro-actively search for solutions while the systems are still functioning.

Beginning the process of looking for a solution once the drilling has been brought to a halt, potentially for safety reasons, is already a lost battle. Site operations personnel need to interpret big data and continuously make provisions in case something goes wrong in the future.

Having this pre-emptive big picture view saves money and potentially lives. What’s more, it gives engineers the insight they need to choose the best supply chain solution to suit their needs.

If you are drilling in the North Sea and realize that one of your pumps, motors or inverters is coming to the end of its life, then you must think ahead. Where can you get the part quickly and at a reasonable price? When you finally get it delivered, what guarantees do you have that it will work? When is the best time to schedule the repairs? Will you need additional support during maintenance?

Often you will be in a situation where, for traceability and validation purposes, the new part will have to be identical in every way to the old one. Unfortunately, thanks to the long lifespan of most upstream applications, the old part can often be obsolete, or at the very least extremely rare by the time it needs replacing.

It’s quite possible that you won’t have the time or financial resources to wait for the part to come from old stock elsewhere in your business. Equally, as a site manager you won’t be able to stock all the parts you may or may not need. It can be counterproductive to keep large stocks of rarely purchase items.

Just in time

Just-in-time philosophy teaches us that everything needs to be calculated with extreme precision. You shouldn’t have unnecessary stock taking up space in your warehouse and monopolising the company’s capital—this is the challenge set by lean industry thinkers.

Although the savings are considerable when applying lean techniques, oil firms subject themselves to very high risks. A fragile supply chain, with delicate links can result in millions of pounds spent on replacing broken components when an emergency arises.

So it becomes imperative that, as a site manager, you create provision for a robust logistics chain that will not disappoint. The best way to do that is to create relationships with spare part suppliers that are committed to delivering the products you require as you need them.

Try looking for a supplier that doesn’t rely on their warehouse alone, nor on those of a handful of preferred manufacturers. A good supplier will employ multi-sourcing tactics that ensure there is an entire network of manufacturers and distributors available to supply each type of component. This ensures that when a customer in a mission critical market places an order, the supplier can pick and choose the product with the best price and quickest delivery option.

This can sometimes be true even if you need an exact match for a component. For instance, did you know that many Omron and Yaskawa inverters are identical in every way, except the badge on the front? A good obsolete component supplier would,

Supplier qualification is another essential policy to apply to the logistics chain. At Industrial Control we don’t just look at the capacity of one manufacturer. We also do a risk assessment on the financial health of the company, its infrastructure, and product quality and last but not least, company culture.

Energy exploitation companies need to look at their supply chain and only place their trust in companies that can really deliver. However, even after satisfactory audits and financial checks you may end up with a less than ideal provider.

One way of sparing yourself the headache is to partner with a one stop shop that guarantees supply, repairs, service and exchange, alongside a sturdy logistics chain that will not break down.

Modern oilmen know that luck and gut feeling are no longer enough when drilling for that next big win. Assessments of all kinds, countless hours in the lab and big data analysis are the tools they need in order to ensure safe operations, free of unplanned downtime.
