Yokogawa acquires RAP International

Yokogawa Electric Corporation has signed an agreement with UK-based RAP International (RAP) for Yokogawa to acquire the company and make RAP a wholly-owned subsidiary.

RAP specialises in providing digitised solutions that support risk assessment, management of the permit to work (PtW) process, and governance of control of work (CoW) for all plant maintenance activities.

Integrating RAP’s electronic risk assessment and PtW software solutions with Yokogawa’s real-time plant condition monitoring will improve safety assurance, reduce turnaround times, and support customers in providing enhanced protection for their people, assets, and the environment.

Manufacturing plants rely on scheduled and unscheduled maintenance activities to keep operating, ranging from daily rounds by field service personnel to the replacement of major pieces of equipment that can require shutdown of the entire plant for days or more. Control of work is the setting in place of a predetermined system for maintenance so that all necessary steps are carried out to prevent accidents and injury to people, damage to equipment, and unwarranted release of materials into the environment. However, in many plants these CoW systems are still paper-based or semi-automated through a combination of bespoke spreadsheets and document management systems, which can contribute to human error during operations.

Since 1994, RAP has been developing and implementing software solutions with integrated best practices that let customers digitise their CoW processes to make their maintenance activities safer, more accurate, and more efficient. RAPnet, its flagship product, is a comprehensive and easy to use electronic CoW system for automating maintenance processes: it is built around a large knowledge base incorporating decades of accumulated first-hand knowledge and experience. The digitised off-the-shelf solution includes standard modules for safety risk assessments, PtW management, management of change, interlocks and overrides, and isolation management. The system is complemented by consulting services as well as mobile and cloud-based functionality to fully deliver on the digital ambitions of customers. With support for 25 languages, it has already been implemented at over 150 locations in 30 countries in the oil, gas, chemical, utilities, and steel sectors.

Yokogawa provides industrial automation solutions to optimise productivity and efficiency whilst at the same time assuring plant safety and asset integrity. The company offers solutions that can monitor the health of plant equipment, and a digital platforms to support field maintenance. RAP solutions will further enhance the Yokogawa asset and safety assurance value proposition. Yokogawa will expand the availability of RAP consultancy services and road-tested systems through its global sales network, starting in Europe. The company will also carry out development work to integrate these into its existing technology portfolio and create a digital transformation platform that enables real-time monitoring of both plant assets and maintenance procedures.

Simon Rogers, head of the Yokogawa Advanced Solutions Division, commented: “Yokogawa believes that to create unique value for our customers it is important to integrate domain knowledge into the technology solutions we deliver. RAP systems are built around manufacturing industry best practices developed over the past 25 years, enabling customers to digitise and transform their maintenance safety processes, better protect their workforce, and improve operational efficiency. One of the strategies laid out in our Transformation 2020 mid-term business plan is to expand our OPEX business, so in line with that we look forward to making this outstanding addition to Yokogawa’s safety assurance portfolio available to our customers around the world as soon as possible.”

The European Scene

The German organisation Profibus & Profinet International (PI) publishes annual statistics on the numbers of devices installed with interfaces equipped with their communication technologies, which also include ProfiSafe and IO-Link. The trend towards Profinet increased in 2017, with 4.5 million new nodes installed, an increase of 25% on the previous year figure, which brings the total number installed to 21 million. Possibly because of the rise in Profinet systems, the Profibus DP numbers added seem to have reached a plateau over recent years, with a population of 60 million.

Profibus PA and ProfiSafe node numbers are growing strongly in the process automation field, with the ProfiSafe adoption growing 25% in the year, adding 2m nodes to reach 9 million in total. Similarly IO-Link device numbers installed in the year increased 50%, adding 2.8m to achieve a population of 8.1 million, linking sensors and actuators to a PLC as a subsidiary network below the fieldbus/Profinet level. PI recently published an IO-Link wireless specification, and demonstrated the technology at the Hanover Trade Show earlier this year.

Government Interferences

Legislative rulings have affected businesses and consumers across the EU recently, with the European Union’s General Data Protection Regulation (GDPR) causing avalanches of email asking for a subscriber’s permission to be re-registered with every firm they have ever dealt with, to allow them to record the fact. Even companies from outside the EU will face financial penalties, if they send out emailed newsletters or promotional messages into EU subscribers, without having these permissions confirmed, registered and recorded!

In the USA, the EPA, under the Trump administration, has dropped most of the more Draconian measures that they had originally proposed to impose on chemical plants, after the explosion at West Fertilizers in Texas that killed 15 fire-fighters and injured 260 people. The CSB report on the incident also listed 19 other Texas facilities that store large amounts of Ammonium Nitrate fertiliser, and are located within half a mile of a school, hospital or nursing home. One regulation that will be introduced in Texas is that local fire marshals will inspect all sites storing ammonium nitrate, once a year. Hopefully this might help prevent any further explosions that might result in large off- site consequences.

The changes that were proposed by the EPA and that will not now be introduced include (1) the need to evaluate options for safer technology and procedures that would mitigate hazards; (2) the requirement to conduct a root-cause analysis after a catastrophic chemical release or potential release incident; and (3) performing a third-party compliance audit after an accident at a plant involving the release or potential release of chemicals.

In the UK, Barclays Bank, rather than the Government, is reassuring UK exporters worried about Brexit and trading afterwards, with a survey that shows 39% of International customers would be more inclined to buy a product if it displayed the Union Jack. This was especially true for consumers in Asia and the Middle East (India, 67%; UAE, 62%; China, 61%), and also for younger consumers generally, where nearly half said this would encourage them to make a purchase. For over 55 year olds (who maybe had more life experience) the figure dropped to a quarter. It’s all statistics!)

Research projects

Splitting water into hydrogen and oxygen was first demonstrated by Fujishima and Honda using a titanium dioxide electrode. Since then, scientists have been on the hunt for the ideal material to perform the task, as Hydrogen is a very useful, green fuel for portable power. Now, a team from Exeter University has made a significant hydrogen energy breakthrough, developing an electrode that splits water using only light. The photo-electrode, which is made from nanoparticles of lanthanum, iron and oxygen, absorbs light before initialising electrochemical transformations to extract hydrogen from water. The team is currently working on further improving this material to
make it more efficient, to produce more hydrogen.

At the Drives & Controls Exhibition in the UK this year all the motor manufacturers were showing the condition monitoring capabilities of their offering, usually measured by vibration monitoring sensors. Possibly ABB went one step further, showing a sensor assembly that can be attached to almost any low-voltage motor, existing or on a new project. Transmitting information over Bluetooth, the sensors require no wiring, and are attached directly to the motor’s frame. Within the unit, sensors collect vital data points like vibration, sound and temperature, and upload that information via an ABB gateway or Smartphone to the cloud, where it is analysed. The results are sent back for optimising performance and predictive maintenance, just like a roving maintenance engineer!

Sales and marketing people to admire

With the Farnborough Air Show coming over the horizon, in 2018, I thought it might be relevant to look again at the story first told in the SA Instrumentation and Control journal in 2016, just after the last Farnborough event.

First, the retail example

There is a family-run DIY shop in Winchester: it does not have the attractive displays of the DIY Supercentres, it is crammed with stuff in crowded aisles, and you have to ask where to look for anything. But then the staff know exactly where it is, are knowledgeable about how to use it, and make a good guess as to why you want it, and suggest two other things that might also be useful. So you come out with more than you wanted, but with reassurance. More important, they made the sale, helped the customer, and sold a few more bits. You have to admire their sales expertise, and their business just keeps on growing. Back in 2016, they proudly boasted that it was Rick Stein’s favourite D-I-Y shop!

A different approach, in industrial calibration

The Trescal postcard give-away

Occasionally you recognize similar marketing initiative in industry. In the public display days at the Farnborough Air Show 2016 there were aircraft enthusiasts (like me) lined up along the barriers, all probably with jobs that impinge on aviation, or engineering, or similar. So while waiting all day for his 10 minute display slot, Jean-Marc d’Hulst, the pilot of a French Starduster SA300 aerobatic biplane, walked along the crowd line handing out postcards showing his aircraft, chatting to anyone interested, and listened to by everyone around.

Turning the postcard over you realize that it is advertising the Trescal Group – which explains the name painted on the side of the aeroplane. This group is a world-wide network of companies that provide calibration, repair and verification services, specialising in the requirements of the avionics industry. These days, with traceability and accountability paramount, such services are in high demand, not just from the aerospace industry, and are usually bought in from a third party, so the records can be seen as from independent inspectors, and the third party supplier takes on all the hassle of maintaining the traceability for their test equipment.

Jean-Marc d’Hulst is a VP of Trescal: the company news on their website shows they seem to acquire another laboratory in another country every few months. They now have 180 laboratories in 21 countries: these labs cover Europe, Asia, USA, South America and North Africa at the moment. Trescal also provide engineering training and consultancy on measurement problems to improve process performance for all types of industry. Jean-Marc has displayed this year at the Paris, Farnborough, Berlin and Marrakech air shows, and indeed his company expertise was also broadcast during the public commentary at each display. With these marketing skills also applied to the group acquisition and expansion strategy, maybe Jean-Marc will take his Starduster display to South Africa very soon!

2017 Update

While the comment about South African expansion was aimed at the readers of SAIC, the news this November is that Trescal has made another acquisition in South America, Trescal has acquired Teclabor, a calibration services provider based in Recife (Brazil). This is the third acquisition in Brazil, expanding their local geographical coverage into Pernambuco state.

Founded in 1985, Teclabor is an accredited one-stop-shop calibration laboratory, with strong capabilities in liquid flow, volume, mass (scales), temperature and humidity. Teclabor employ 30 people, generating a turnover of 3,3 million Brazilian Reais (approx 1,0 million Euro), and is mainly active in the Food & Beverage sector.

During 2017 Trescal has also acquired several other companies: Gebhardt Instruments in Germany, Acucal Inc in the USA, and Pyrometro Services in Malaysia.

 

The mystery of intelligent sensor diagnostics

The fashion, or trend, that has developed over the last few years for process and analytical instrumentation sensors is to use their on-board intelligence to monitor their own performance status. They achieve this by monitoring and tracking various diagnostic measurements – secondary parameters where consistent values are said to indicate the sensor is working as it should, and has not been subject to any changes since leaving the factory.

This approach is easily understood if you consider the possible effects of exposure of a sensor to excessive temperatures, which might soften the potting or glues holding a sensor to a ‘window’ – and it can be expected that this would be detectable. The addition of a diagnostic sensor, such as a temperature probe, within the sensor housing, could also be an option for checking the sensor condition, and alarming if the sensor exceeds a high or low set-point.

But how else do sensors check their own performance, and how relevant are these “checks”? This topic was discussed in the latest issue of the South African Journal of Instrumentation and Control, August 2017 issue: SAIC is a journal produced by technews.co.za.

Modern (intelligent?) sensors

So, over the past two years of attending and listening to presentations, and reading relevant articles describing the advantages of self-monitoring systems and sensor diagnostics, waiting for an engineer’s explanation as to how the clever monitoring system actually tells the factory instrument engineer anything, it is a bit of a disappointment to report that there seem to be no suppliers that actually make any significant disclosure. This applies across sensors ranging from ultrasonic and Coriolis flowmeters, electromagnetic flowmeters, level measurement systems using radar or ultrasonics, and level alarms. Obviously all the major suppliers are involved in such equipment, and compete with each other, but this secrecy seems a little extreme.

The problem is possibly that until a manufacturer can point to a failure that was detected – or anticipated – using their diagnostics, and decides to publish it, the user population has no idea what systems might actually work. But equally, by publishing a success for the diagnostics, the same manufacturer is saying that one of his sensors failed – and that is a very unusual event, these days. Plus also maybe not something they would wish to publicise.

The older approaches

The whole idea of diagnostics and sensor monitoring has been around for a long time. From personal experience with Bestobell Mobrey, in the 1980s, Mobrey launched an ultrasonic version of a float switch, the ‘Squitch’, which switched a two wire mains connection through a load circuit. When not alarmed it just sat there taking a small control current. For customer reassurance that it was operating in this quiescent state, there was a blinking red LED to show that the sensor was ‘armed’ and operating normally. Mobrey called that a heartbeat indicator, a term that is now used more widely.

For custody transfer flowmeters, the classic approach to validate confidence in the reading is to use two meters in series, and check that both give the same answer. This has progressed to having two separate ultrasonic flowmeters mounted in the same flowtube, on some installations.

For the more safety conscious plant there are often requirements for duplicated sensors for such duties as high level alarms, where two different technologies are used by the sensors – e.g. by mixing float, capacitance or ultrasonic level alarms.

The modern approach

It seems that the ultimate approach is to let the sensor supplier link into your plant automation and data system to interrogate the sensor, and he will verify the measurement and performance diagnostics on a regular basis. With many and varied sensors, this leads to a lot of external interrogation of your plant assets, and possible worries over losing control of your plant.

Overall, it begins to look as though it is becoming impossible for a discerning plant engineer to decide which supplier has the best performing diagnostic system to monitor the relevant sensor’s performance. Rather like opening the bonnet of a modern car, and deciding it would be best to take it to a garage!

At a recent lecture on this subject, held by the InstMC Wessex section in co-operation with Southampton University, a detailed discussion concluded that the sensor suppliers now have all the real expertise in-house and a normal plant engineer could not be expected to cover the depth of this technology for all the many sensors and other equipment within his control. In the end the decision as to ‘which supplier to use’ returns to your own previous experience, including the service and support that has been and is now on offer, and the suitability of the product for the money available for that sensor task.

Yokogawa/Cosasco ISA100 deal

Yokogawa has signed a sales agreement with Rohrback Cosasco Systems, a US-based manufacturer of corrosion monitoring systems to distribute the Cosasco ISA100 wireless-based MWT-3905 and CWT-9020 corrosion monitors: also Cosasco will distribute the Yokogawa ISA field wireless system devices. Yokogawa systems operating to ISA100.11a-2011 include an application layer with process control industry standard objects, device descriptions and capabilities, a gateway interface, infrared provisioning, and a backbone router.

Yokogawa therefore has now added corrosion sensors to its line-up of field wireless devices that help customers efficiently maintain facilities and ensure safety at their plants. For Cosasco, the ability to offer its corrosion monitors in combination with Yokogawa field wireless devices is expected to increase sales.

Yokogawa Objectives

With a field wireless system, plant field devices and analysers are able to communicate wirelessly with host-level monitoring and control systems. The rising need to improve productivity and enhance safety by collecting more data on plant operations is driving the demand for field wireless devices, which can be installed even in difficult to access locations. Field wireless devices have the added advantage of reducing installation costs.

Yokogawa has developed ISA100 Wireless-based technologies and products such as wireless access points and management stations, and Cosasco has a long global track record in supplying various kinds of corrosion monitors to the oil and gas, petrochemical, chemical, and other industries. Through this agreement, Yokogawa aims to increase sales for its field wireless business by being able to offer a wider field wireless device lineup.

Cosasco Wireless Corrosion Monitors

Yokogawa IA - Cosasco MWT-3905 corrosion monitorCorrosion sensors monitor the thinning or deterioration of the metal walls of pipes and other installations. A variety of technologies are employed, including electrical resistance and ultrasonics. The Cosasco MWT-3905 and CWT-9020, the devices covered by this sales agreement, are direct measuring type corrosion sensors that use high speed electrical resistance and linear polarisation resistance (LPR) technology. This enables corrosion rate measurement at a low installed cost in all process environments, including hazardous areas. The units are particularly applied for the monitoring of corrosion in facilities at offshore platforms and other types of oil and gas installations, plus petrochemical plants, chemical plants, and water and sewage treatment plants.

Rohrback Cosasco is a part of Halma plc, a UK conglomerate.
