Il futuro del calcio mondiale: LA VAR TECHNOLOGY

Un saluto a tutti i lettori del blog,

io sono Marco, un comune studente di ingegneria e appassionato di calcio e sport in generale. Grazie alla possibilità che mi è stata data dal corso di Rivoluzione digitale del Politecnico di Torino, ho potuto aprire questo blog insieme ad altri due compagni di corso riguardo “la tecnologia applicata allo sport”.

Sembra ormai ovvio, nel 2017, parlare di tecnologia per tutti gli ambiti della vita, sport compreso. Da buon italiano amante del calcio, non posso rimanere indifferente sulle continue discussioni che si vengono a creare riguardo gli errori arbitrali.

Per aiutare le terne arbitrali (che ormai sono diventati 5 collaboratori e un giudice di gara), gli organi di controllo del calcio europeo e mondiale, stanno testando la “VAR TECHNOLOGY”, che consiste in un ausilio tecnologico in SITUAZIONI OGGETTIVE per correggere in seduta stante eventuali errori commessi dagli arbitri.

Mi sembra ovvio, che ciò sia un cambiamento necessario per il miglioramento del gioco in un futuro prossimo. E’ sempre più probabile infatti, l'utilizzo di questa tecnologia durante il prossimo campionato della lega di serie A 2017-2018.

Molti altri sport come il basket e il tennis hanno, già da tempo, abbracciato l'utilizzo della tecnologia, traendone benefici a breve e a lungo termine.

Nonostante gli evidenti benefici che la tecnologia porterebbe, alcuni puristi del gioco affermano che l'introduzione della VAR TECHNOLOGY snaturerebbe l'essenza del gioco del calcio rallentando troppo il gioco.

A confutazione del rallentamento delle partite, sono già state fatte alcune prove con la VAR TECHNOLOGY sul tempo di decisione di un episodio dubbio, riportando tempi morti assolutamente esigui, magari riguardo un fuorigioco.

L'utilizzo della GOAL-LINE TECHNOLOGY è un esempio di come la tecnologia, se ben applicata, può portare benefici già nell'immediato, dando sicurezze maggiori ed evitando futili discussioni.

In conclusione è bene ricordare però, che la VAR TECHNOLOGY non andrebbe a sostituire il giudice di gara, il quale rimarrebbe detentore delle decisioni, si deve invece considerare come uno strumento da consultare per eventuali dubbi.

La VAR avrà sicuramente bisogno di un adattamento e gli assistenti all’inizio potrebbero commettere errori di valutazione nel guardare le immagini proposte, ma con il passare del tempo, il numero di errori corretti arriverà ad essere la vera conquista della tecnologia applicata al calcio.

VARTECH™ INDUSTRIAL SYSTEM CLEANER (ISC) HELPS ENHANCE TURBINE EFFICIENCY BY VANQUISHING VARNISH

Varnish is the nemesis of any gas turbine. A coating that adheres to internal surfaces, Varnish can take different forms, from a sticky coating to a hard lacquer, and ranges in color from gray to brown to amber. It has the capability to wear out equipment components, restricts performance and can ultimately cause failures. Understanding varnish and its formation is the starting point to vanquishing it.

It is formed when high operating temperatures deplete protective additives, causing the lubricant to oxidize and break down. The oil is further degraded by water, chemicals, particles, gasses and other contaminants also act to degrade the oil. Elements of this degradation, known as varnish precursors, attach themselves to internal surfaces. The tacky nature of these deposits only attracts more and more precursors, leading to the buildup of varnish layer by layer.

With the worsening of varnish, a vicious cycle is often set in motion. More degradation results along with less effective lubrication resulting in the creation of more varnish precursors & layers with the problem spiralling towards equipment failures.

Even the tiniest amount of varnish can cause poor system performance and equipment failures. Valves stick, bearings overheat, components wear out, oil inlets and filters clog, and the internal mechanics of your turbine malfunction, and in the long run, these issues only multiply leading to shortened oil life, poor efficiency of the turbines, and premature shutdowns.

This is when VARTECH™ Industrial System Cleaner (ISC) can make a world of difference. This solution utilizes proprietary technology to eradicate varnish that has infiltrated your turbine system by doing the most thorough and efficient cleaning job without creating operational constraints.

Its triple-action technology cuts through the hard varnish layers and removes them as micro-sized particles; captures and stabilizes these varnish particles in a protective barrier so they can be removed from your system without redepositing in other parts of the equipment; and is compatible with the in-service oil for optimum operational flexibility while maintaining performance during the cleaning cycle that prepares the system for change out to fresh oil.

Using VARTECH™ Industrial System Cleaner (ISC), turbines remain online and productive with varnish micro-particles that are gradually removed to avoid overwhelming. Its cleaning process is simple, streamlined, and economic, unlike conventional system cleaners that are more complex and require additional steps, external filtration, and multiple rinses and compatibility tests.

VARTECH TECHNOLOGY:  AN UNBELIEVABLY EASY METHOD THAT WORKS FOR YOUR GAS TURBINE

To understand how VARTECH Technology can work incredibly well for your Gas Turbine, it is important to understand varnish and the problem it creates.

Varnish is a broad term covering various kinds of deposits in oil systems. Some types are rigid and firm, others sticky, and others are commonly referred to as sludge. However, the common factor is that they typically begin from the degradation of the oil in the system.

Varnish usually forms and sticks in areas that are extremely hot or very cool and sluggish.

Now, measuring or finding varnish is an enormous challenge since varnish does not turn up in the oil, but on the metal surfaces. The only way to identify varnish is to see it on a surface or to experience its effect. For example, a sticky valve is an apt indicator of the presence of varnish.

It is triggered in many ways. The cycle of varnish begins with something that upsets the lubricant’s stability, such as excessive heat. This can lead to the degradation of the oil, resulting in the formation of impurities. For a while, these impurities often remain dissolved in the oil, causing no harm. But, as more and more accrue, however, they stick together, forming insoluble, suspended submicron particles and once they stick to metal surfaces, they become varnish.

Varnish accumulation reduces a lubricant’s heat transfer properties and causes your system to run hotter and hotter. The consequences won’t just jeopardise your equipment — it will cause de-rated equipment, unpredicted shutdowns, inefficient operation, enhanced maintenance labor management, and spending, higher costs, and lost profits for the owner.

In some turbines, varnish focuses on servo valves, causing them to stick and either delay movement or refuse to move, which can send the turbine out of operation, causing a complete shutdown. In a peaking turbine, one that is held in reserve for peak demand, stuck servo valves can lead to failure to start. Downtime and repair costs can run anywhere from $100,000 into the millions.

Varnish buildup in gas turbines is a big concern for our industrial lubricant customers. While some cleaners in the market are effective in certain circumstances, they may also present several issues. But, VARTECH Technology has addressed the issues of greatest concern, namely water separability; oxidation stability; and seal compatibility.

Residual dispersal/detergent cleaner remaining in the oil system when the oil is changed can ruin the fresh oil that is installed. To ensure that the cleaner is expunged from the system, a full flush is required.

This is where VARTECH™ Industrial System Cleaner (ISC), can come into play. A non-solvent-based solution that can be added straight to oil during operation, VARTECH technology cleans varnish and sludge from the system before a regular oil change. In exhaustive lab testing against existing products, Chevron VARTECH™ ISC showed very good seal compatibility, water/oil separability, and oxidation performance.

To understand how VARTECH Technology can be an incredibly easy method that works for your gas turbine, we can take a case in point of offshore production platforms with three turbines on board. The turbine in question had a severe varnish issue and the oil cooler had been contaminated, rendering the temperature rise to where the operators would have to shut the turbine down to replace the cooler.

VARTECH ISC was added and over one hour, the main oil header temperature dropped around 10 degrees, from too high to normal. The product had an immediate effect on the operating conditions of the oil cooler. In comparison, when the previous dispersant/ detergent product was used, it took two days to see a temperature drop.

That product was also blocking the filters in the system frequently with varnish debris. VARTECH ISC had no such filter plugging effect over the two-day test period. Subsequent testing continued, it revealed that VARTECH ISC outperformed many other commonly used cleaners in cleaning efficiency, effectiveness, and system compatibility without drastically affecting water separability and oxidation stability. This compatibility also reduces the performance impact for the fresh oil when flushing is unfeasible, and it does not need to be used in combination with a varnish filtration system. It is not recommended not to leave any varnish cleaner in a system indefinitely. Simply add VARTECH ISC before a scheduled oil change, and the removed varnish debris will come out with the old oil.

EXPERIENCING UNPLANNED DOWNTIME? USE VARTECH

Plant managers have a lot of challenges to overcome daily.

However, nothing is more dreaded than the sudden shutdown of a production unit or line because of equipment failure. According to recent studies and research, almost 82% of companies have experienced unscheduled shutdowns in the past three years, costing the industrial plant up to $260,000 an hour, cessation of delivery services to customers, and overall loss of customer trust and future sales.

These disastrous consequences mean that plant managers need to be watchful about averting unexpected outages. But, reality and research prove otherwise. Research survey reveals that most plant managers do not know when their vital production equipment is due for maintenance, upgrade, or replacement. According to the International Society of Automation, industrial facilities lose nearly $650 billion per year to unplanned equipment outages and missed production.

These alarming figures and statistics reveal that unplanned downtime is more than just a headache, one that most plant managers struggle with.

What causes these unplanned downtimes?

The big question that remains is the reason behind these unplanned downtimes. Three common causes of unplanned outages and shutdowns have been highlighted that need urgent attention in order to prevent financial losses.

Reactive maintenance processes, where maintenance teams wait until there is an observed issue with equipment have been mentioned as a common reason. The problem with this process is it relies on a technician to find and identify a problem, such as a leaking pipe or damaged part before action is taken. The drawback of this process is that a problem could go unnoticed for some time if it’s not obvious and could become urgent by the time someone finds it. This often results in maintenance managers quickly re-prioritizing and communicating with their staff to fix the issue. Lack of spare parts could lead to delays of several days to order and get an additional part. Meanwhile, operations could be hindered or even shut down if the issue is serious.

A lack of clarity into maintenance work processes is another critical issue leading to unexpected downtime. Mainly because, managers issue work orders to field technicians in paper dossiers leaving them uninformed on a daily basis of what’s happening in their plant.

Poor communication between supervisors and field techs, precipitated by paper-based work order management processes, could also cause a mix-up.

Solution to the big question: Vartech

Caltex lubrication experts have created select GST ® Advantage turbine oils with VARTECH™ Technology. Using proprietary triple-action technology, Vartech ISC, in one sweeping move, can indirectly do away with unplanned downtimes.

How?

Even the smallest amount of varnish can lead to poor system performance and equipment failures. Valves stick, bearings overheat, components wear out, oil inlets and filters clog, and the internal mechanics of your turbine can malfunction. These issues worsen over time as more varnish builds up, resulting in reduced oil life, poor equipment performance, and untimely stoppages.

Vartech’s two-step, clean-and-control solution can help you protect equipment from varnish and ensure peak productivity in your operation. The advanced lubrication chemistry used in VARTECH™ Technology prevents the formation of varnish precursors, products of oil degradation that can deposit on internal surfaces and build up over time.  Additionally, after the existing varnish has been scrubbed from your gas turbines, Vartech’s advanced lubrication chemistry prevents the precursors that can form in your oil stream, deposit on internal surfaces and eventually become varnish. Moreover, Vartech ISC is also compatible with the in-service oil for optimum operational flexibility while maintaining performance during the cleaning cycle that prepares the system for change out to fresh oil.

VARTECH™ TECHNOLOGY – HOW RELIABLE IS YOUR EQUIPMENT AGAINST FLUID DEGRADATION?

Fluid degradation is bound to cause many kinds of equipment failures. A lubricant in service is often subjected to a broad range of conditions which can degrade its base oil and additive system. Such factors include heat, entrained air, incompatible gases, moisture, internal or external contamination, process constituents, radiation, and unplanned mixing of a different fluid.

However, today’s users of industrial lubricants are up against other challenges. Chief among them is deciphering the nature of the deposits or varnishes. Often, just by looking at the brown color of a deposit, one assumes it must be the same as the brown sample that was previously observed. These assumptions are risky since they can lead to taking the wrong corrective actions.

This is where utmost precaution needs to be taken and a careful plan of action followed.  

First, it is imperative that we broaden our thinking of sludge or varnish. This material is not just simply the oxidation or degradation products from the lubricant - it is the material coming out of the fluid with the potential to cause operational issues. Equipment reliability issues are not only caused by fluid degradation and varnish deposits but also by any material that is not a homologous single phase with the lubricant. Therefore, any foreign material causing deposits in the lubricant can potentially be categorized in this category.

Since there are many mechanisms that weaken lubricants, sorting deposits into classification bins is helpful to better discern the source of the deposits and determine the right remediation process.

Next, there is a need to carry out the root cause analysis (RCA) to identify what happened, why it happened, and what can be done to stop it from happening again. It involves examining the problem and considering proof from several viewpoints.

Often, the deposit components can also be spotted within the in-service fluid. Also, the overall condition of the fluid speaks volumes about the formation direction.

After accumulating as much data as possible about the fluid condition, the deposit can be characterized. A proper analysis of the deposit is often the root cause determination itself. Specifying the deposit source classification will help establish the actions to take when fixing the cause. Several times, the deposit contains over one deposit classification. That information can support this root cause determination.

With a root cause and deposit classification designated, one can focus the efforts toward the elimination and removal of the tar-ball deposits. The chemistry of the deposit details the mitigation strategy since any one deposit removal technology is incapable of removing all deposits. Also, it is often favorable to cease the deposit formation before trying to discard it.

This is when industrial operators need to take notice of VARTECH Industrial System Cleaner (ISC), a two-step, clean-and-control solution that uses proprietary technology to carry out efficient cleaning without creating operational constraints to protect equipment from varnish and ensure peak productivity in the operation. The advanced lubrication chemistry used in VARTECH Technology also inhibits the formation of varnish precursors, products of oil degradation that can deposit on internal surfaces and build up. You get exceptional oxidation stability, less degradation, and long oil life—a breakthrough approach to varnish control.
