Leak Detectives Use Victorian ‘Stick’ To Save 900 Million Litres Of Water

A crack team of leak detectives has tracked down and plugged more 18,000 hidden pipe leaks in the North West over the past 12 months –  thanks to a device that has been used since the Victorian era.


The 140 strong team from United Utilities saved an average of 900 million litres of water – the equivalent of 360 Olympic sized swimming pools – using wooden ‘listening sticks’.

The long wooden sticks with an ear-trumpet style end vibrate when a leak is detected, producing a distinctive sound. They have been used for more than 100 years and are still a staple for modern leakage engineers.

Many of the most wasteful leaks are underground and hidden from view, requiring the team to rely on good hearing, old fashioned know how and latest digital technology to find them.

Digital sensors and remotely operated pressure monitoring equipment are also used to turn the tide on hidden leaks.

Many leaks are detected late at night, when reduced traffic noise makes it easier to hear the sound of escaping water.

Hannah Wardle, United Utilities leakage manager said: “We’ve spotted and stopped thousands of leaks over the past 12 months, using a combination of tried and tested, old fashioned techniques, and cutting edge technology.

“These leaks are often hidden under the streets, with no visual signs that water is being wasted. We track many of them down at night, when it’s easier to hear the escaping water.

“We encourage our customers to save water around the home, as it makes good economic and environmental sense. Our nightly battle against hidden leaks is a way of keeping our own house in order. “

Disc Pack Coupling Range Expanded & Meets Standard API 610 for Centrifugal Pumps

CategoryCouplings   
  
Hits:
۶۹



The LP disc pack couplings range, made by R + W and available in the UK from Drive Lines Technologies Ltd, has been expanded with new sizes and updated to meet the latest API (American Petroleum Institute) standard API 610 for centrifugal pumps in the petrochem industries.


Disc pack couplings consist of two coupling hubs and a spacer tube mounted to the disc packs by high-strength screws and bushings. The disc packs are made of highly elastic, corrosion-resistant spring steel, while the hubs and spacer are made from high strength steel materials.

The updated models maintain the range’s established reputation for transmitting power solely by friction between the discs, with no shear forces being exerted on the bolts. This ensures a perfectly even distribution of load and thus avoids stressing of the bolts, minimising wear and, consequently, premature failure.

R + W has doubled the number of sizes of disc pack couplings it offers. The torque remains from 300 to 12,000 (Nm) rated torque and maximum torque ranging from 700 to 24,000 (Nm), but an extra intermediate option between each existing size has been introduced. This means that users can choose an optimum sized coupling rather than having to fit an oversized one.

There are also more options for customisation, such as shorter intermediate spacers, fully-split clamping hubs, and longer drive shaft. R + W expects that about half of users will require couplings that are significantly customised, hence the flexibility built into the new range.

Within the range, the LPAI model also meets all the requirements of API 610, ISO G6.3, and AGMA class 9 for minimum balance quality. It features an intermediate tube that is removable without disturbing adjacent equipment and has an integral safety catch in case of disc pack rupture.

API 610 relates to centrifugal pumping applications in the oil, gas and hydrocarbon industries, but also includes a section on couplings which defines the balance and handling requirements that need to be met so that smooth running is maintained at all times.

In summary the LPAI is a low wear and maintenance-free coupling that allows for easy-handling to access pumps and motors without having to disturb the adjacent equipment.

To help comply with API 160, the LPAI is described in Imperial physical dimensions and performance ratings rather than metric, a first for R+W.

Improving Worker Safety with Automatic Tank Gauging

Improving Worker Safety with Automatic Tank Gauging


By Christoffer Widahl, Senior Strategic Product Manager, Emerson Automation Solutions


The use of manual tank gauging is still common in the oil and gas industry, but it is a method which can compromise the safety of the workers making the measurements. In February, 2016, the U.S. National Institute for Occupational Safety and Health (NIOSH) and U.S. Occupational Safety and Health Administration (OSHA) jointly issued a hazard alert 1 for workers involved in manual tank gauging and fluid sampling at oil and gas extraction sites. This alert identified the health and safety risks posed by exposure to concentrated hydrocarbon gases and vapors, and exposure oxygen-deficient atmospheres—and the potential for fires and explosions when hatches are opened on production and flowback tanks, or other tanks containing process fluids.


The alert states how opening tank hatches, often known as “thief hatches,” can cause high concentrations of hydrocarbon gases and vapors to be released. For workers performing this task, these exposures can have immediate damaging health effects and can even prove fatal. NIOSH and OSHA identified nine worker deaths from 2010-2014 that occurred while workers manually gauged or extracted samples from production tanks. Exposure to hydrocarbon gases and vapors and/or oxygen-deficient atmospheres was believed to be either a primary or contributory factor in those deaths.


What happens when a thief hatch is opened?


When a thief hatch is closed, hydrocarbon gas and vapors in the tank are often at a pressure higher than atmospheric. When the hatch is opened, a large volume of gas, mostly propane and butane, rush out. These gases can displace oxygen in the immediate work area, possibly asphyxiating workers in the vicinity. As the hatch remains open, heavier hydrocarbon molecules (pentane, hexane, heptane) also begin to leave the tank and enter the workspace. The rate of release is high, and these gases and vapors may reach toxic or flammable concentrations. As the hatch remains open, the gases and vapors in the tank approach equilibrium with the environment, significantly slowing the rate of emission.


When workers suffer acute exposure to hydrocarbon gases and vapors, their eyes, lungs and central nervous system can be affected. The NIOSH/OSHA alert states such exposure can sensitize the heart to stress hormones, such as catecholamines, causing abnormal rhythms and ventricular fibrillation, which can lead to sudden death. Even an exposure of less than 30 seconds can result in fatal cardiac arrhythmias, the alert adds.


Improving safety


Operators can take various measures to prevent workers from putting their health and safety at risk through exposure to hydrocarbon gases, vapors and flammable atmospheres, including:


  • Engineering controls such as fitting tanks with sampling taps and thief hatch pressure indicators

  • Improved training and work practices, and

  • Use of protective equipment such as flame-retardant clothing, respiratory protection and impermeable gloves.


However, number one on the NIOSH/OSHA list of recommendations for improving safety is the implementation of alternative tank gauging and sampling procedures, which enable workers to monitor tank fluid levels and take samples without having to open the thief hatch.


Automatic tank gauging systems


Automatic tank gauging (ATG) systems perform a range of measurements within a tank (Figure 1), and can also issue an alert to an operator when action is necessary, for example in the event of the fuel level being too high or low. Critically, these fully automatic systems eliminate the need for workers to climb tanks and open thief hatches, and therefore provide significant safety benefits.



Figure 1: Automatic tank gauging systems avoid potentially fatal hazards for workers while typically delivering greater accuracy than manual measurements.


Although a number of measurement technologies, such as servo and hydrostatic instruments, can be used to perform the principle level measurement, by far the most prevalent is radar technology. Guided wave radar instruments (Figure 2) such as Emerson’s Rosemount 5300, and wireless Rosemount 3308 or non-contacting radars (Figure 3) such as the Rosemount 5400, provide highly-accurate and reliable level measurements largely unaffected by process conditions such as temperature, pressure, density and turbulence. Guided wave radar also offers the benefit of interface level measurement, which enables determination of water and oil levels inside tanks.



Figure 2: Guided wave radar instruments can detect and measure an interface layer between water and oil in a storage tank.



Figure 3: Radar level instruments are immune to the typical application problems (heavy vapors, foam, etc.) typically found in oil storage tanks.


In addition to the guided wave and/or non-contacting radars for level measurement, ATG systems also incorporate temperature transmitters (Figure 4). On well pads, the wired transmitters communicate directly with a remote terminal unit (RTU), or a wireless gateway collects measurements from multiple wireless devices and communicates with an RTU, which in turn communicates with the control room, which may be at a distant location. Monitoring software enables operators to observe and check level and volume measurements easily and efficiently.

Regulations and standards still catching up


Automatic tank gauging is a viable option to keep workers safe on the ground and thief hatches closed, in line with the NIOSH/OSHA recommendations. However, while the hazards of manual gauging are well known, regulations and standards haven’t kept up with technology in the past. Gaps in the standards left manual gauging as the sole option for custody transfer applications on small production tanks.


Until recently, there had been no standard in support of cost-effective automatic tank gauging on smaller production tanks (less than 1,000 bbl), as the existing American Petroleum Institute (API) standard API MPMS 18.1 only covers manual gauging for custody transfer, while API MPMS 3.1B covers automatic tank gauging for custody transfer in inventory storage tanks over 1,000 bbl. Level instruments used for custody transfer, according to API MPMS 3.1B, are a non-viable option for small production tanks as the cost is assumed to be too high. However, a new standard has recently been published which will have a significant impact on how tank gauging is performed in the future.


API MPMS 18.2 standard


The new API MPMS 18.2 standard 2, published on July 1, 2016, allows automatic tank gauging to be used for custody transfer on production tanks. The accuracy requirements for API MPMS 18.2 correlate to what is already installed in the field in many applications, where thousands of radar instruments have been in use for level monitoring, overfill prevention and truck scheduling for years. Operators with existing radar level instruments can immediately start to adopt the new standard, relying on existing units for custody transfer, as long as they can prove the accuracy of the instruments.


As with all instrumentation used for custody transfer, a radar level instrument’s accuracy must be verified periodically. The verification of radar accuracy can be done in just a few minutes and does not require the thief hatch to be opened or any product to be transferred.


Temperature sampling


In custody transfer applications, the fuel’s mass needs to be established, and this calculation requires both its level and average temperature to be measured accurately. Previously—as with the level measurement—the temperature also had to be sampled by manual means. However, API MPMS 18.2 also covers standards for temperature sampling during custody transfer of crude oil from lease tanks to a truck trailer without requiring direct access to the tank’s thief hatch, therefore keeping workers off tanks and increasing safety.


Conclusion


Operators can now use automatic tank gauging for custody transfer applications on production tanks, as it not only complies with the new API MPMS 18.2 standard, but also enables them to follow the NIOSH/OSHA recommendations for increased worker safety.


Use of automatic tank gauging in custody transfer enables efficiency to be increased because:


  • There is no need to gauge manually before and after filling and emptying

  • Emissions are lower because the thief hatch remains closed at all times, and

  • Worker injuries and fatalities related to manual gauging can be avoided by keeping workers on the ground and avoiding exposure to hydrocarbon chemicals.


This combination of technology, industry standard practices and government imposed safety regulations makes for a highly advantageous situation where operational performance, environmental considerations and worker wellbeing all advance together.

InfinityQS Report: Enterprise visibility is the first step to Industry 4.0

InfinityQS Report: Enterprise visibility is the first step to Industry 4.0


February 17, 2017 – InfinityQS, an authority on data-driven enterprise quality, is imploring manufacturers to put down their pencils and papers and implement automated data collection technologies to attain enterprise visibility and begin to adopt Industry 4.0.


According to The Boston Consulting Group’s recent report, Sprinting to Value in Industry 4.0, “The value created by Industry 4.0 vastly exceeds the low-single-digit cost savings that many manufacturers pursue today. The new technologies promise to revolutionize manufacturing, thereby shifting the competitive balance among countries and transforming the industrial workforce.”


However, the foundation of Industry 4.0 is automation and data exchange, and InfinityQS found in its recent survey of 260 manufacturers that 75% of respondents are still manually collecting data. 47% of those rely on pencil and paper. The survey, which included some of the world’s largest manufacturing organizations, sought insight into the manufacturers’ needs, processes, and uses for data collection.


To facilitate Industry 4.0, manufacturers must automate and standardize data collection processes and create a centralized repository that is accessible to all stakeholders within the organization. When data is unified, from all sources, it’s possible to visualize more than a single aspect of operations. The outcome is real-time visibility of the entire enterprise, from end to end — including suppliers, incoming inspection, raw materials, in-process checks from shop floor operators and the quality lab, process data, packaging, and finished products. This visibility identifies potential opportunities to increase output, decrease costs, and improve quality across manufacturing operations.


Michael Lyle, president and CEO, InfinityQS, said, “To reach the full potential of digital transformation, it’s vital to find the right talent and resources to configure and deploy the technologies, as well as interpret the resulting data. However, what many manufacturers don’t realize is that it’s not an all or nothing proposal. There are small, less expensive steps that can be taken to adopt Industry 4.0 in a more iterative and agile manner.”
