National Apprenticeship Week 

At Crowcon we have a passion for gas detection, for over 50 years we have been manufacturing high quality gas detectors that are reliable and have technical innovation. In a week that brings businesses and apprentices together to highlight the positive impact apprenticeships have on individuals, business and the wider economy, we are delighted that we offer such apprenticeships here at Crowcon.  

With over 25 employees having completed an apprenticeship and three currently going through the process, we know apprenticeships are more than just a qualification, they offer experience to become a professional in a chosen trade, helping to make an impact in the business all whilst earning a wage.  

“Apprenticeships are still undercelebrated despite of all the benefits they bring to both the individuals and the business. They perfectly blend theory and practical skills together into a learning-working experience that is like no other. Crowcon has seen many of our colleagues successfully graduate form apprenticeships with HNC, HND and even bachelor’s degrees. I would strongly encourage today’s youth to consider apprenticeship route, especially females within STEM. I have no doubt that it will unlock many career opportunities for you” – Birute Infantado, Human Resources Manager. 

In the process of building your engineering career through an apprenticeship scheme at Crowcon, you will experience a work environment day-to-day in parallel whilst gaining the benefits from experienced colleagues and mentors who can help you build your skills and take them straight into the workplace. 

An advanced apprenticeship at Crowcon takes three years to complete. We work closely with local colleges to provide apprenticeship programs with the opportunity to continue your academic studies at both Newbury College that covers engineering or Abingdon and Witney College that supports business improvement. The scheme combines 80% work and 20% learning time. 

We believe that home grown talent is the future. Although higher education has now become an expectation in the workplace, the cost of higher education is leading many to re-think the automatic study routes. Vocational career paths have become widely available, offering a multitude of opportunities and development routes. People development is at the heart of our business success and working collaboratively to release the wider potential within our business is how Crowcon will continue to go from strength to strength. 

Following completion of the three-year apprenticeship, previous apprentices have developed the scope to move into engineering roles after a few years in the Line Technician position. Not only have all our apprentices been placed in permeant jobs within Crowcon following the end of their apprenticeships, but some have even continued with higher level apprenticeship studies. Some of the previous apprentices have taken roles in Test and Verification, Quality Engineering, Manufacturing Engineering and Project Management within R&D. 

Hear what some of our current apprentices have to say: 

“One of the things I particularly enjoy about the apprenticeship is the fact you earn while you learn, with the opportunity to continue into higher education all supported and sponsored by the company, meaning no hefty student loan. Additionally, with a tailored training and development plan directly related to the job – you pick up a lot of useful/ specialist skills along the way which puts you in line for great career prospects and progression. I would recommend the apprenticeship route as it gives you the opportunity to learn within the industry, whilst putting these into practice in real world scenarios, which is just as valuable as going to university” – Alex Watson, Test and Verification Technician 

“The apprenticeship gave me an insight and understanding into LEAN practice and has given me the tools to streamline production and improve processes.  Working in small teams with other apprentices doing the same course was good as we all had different opinions and views which was also a good learning process for me” – Debbie Murphy, Team Leader.  

“I am currently undergoing Level 3 Engineering Technician course, where I am learning the basics of electronics as well as building and testing my own circuit boards. The apprenticeship is allowing me to develop my social skills as well as get hands on by combining my learning and work together” – Ethan Shurmer, Line Technician.  

“Throughout my time at Crowcon, I have completed 4 apprenticeships from level 3 to level 6. The apprenticeships have allowed me to work in real world environments giving the options to gain the essential experience needed for future careers choices and have provided me with the skills and knowledge to progress further within the engineering industry” – Vikesh Patel, Junior Project Manager.

What’s the difference between a pellistor and an IR sensor?

Sensors play a key role when it comes to monitoring flammable gases and vapours. Environment, response time and temperature range are just some of the things to consider when deciding which technology is best.

In this blog, we’re highlighting the differences between pellistor (catalytic) sensors and infrared (IR) sensors, why there are pros and cons to both technologies, and how to know which is best to suit different environments.

Pellistor sensor

A pellistor gas sensor is a device used to detect combustible gases or vapours that fall within the explosive range to warn of rising gas levels. The sensor is a coil of platinum wire with a catalyst inserted inside to form a small active bead which lowers the temperature at which gas ignites around it. When a combustible gas is present the temperature and resistance of the bead increases in relation to the resistance of the inert reference bead. The difference in resistance can be measured, allowing measurement of gas present. Because of the catalysts and beads, a pellistor sensor is also known as a catalytic or catalytic bead sensor.

Originally created in the 1960’s by British scientist and inventor, Alan Baker, pellistor sensors were initially designed as a solution to the long-running flame safety lamp and canary techniques. More recently, the devices are used in industrial and underground applications such as mines or tunnelling, oil refineries and oil rigs.

Pellistor sensors are relatively lower in cost due to differences in the level of technology in comparison to IR sensors, however they may be required to be replaced more frequently.

With a linear output corresponding to the gas concentration, correction factors can be used to calculate the approximate response of pellistors to other flammable gases, which can make pellistors a good choice when there are multiple flammable vapours present.

Not only this but pellistors within fixed detectors with mV bridge outputs such as the Xgard type 3 are highly suited to areas that are hard to reach as calibration adjustments can take place at the local control panel.

On the other hand, pellistors struggle in environments where there is low or little oxygen, as the combustion process by which they work, requires oxygen. For this reason, confined space instruments which contain catalytic pellistor type LEL sensors often include a sensor for measuring oxygen.

In environments where compounds contain silicon, lead, sulphur and phosphates the sensor is susceptible to poisoning (irreversible loss of sensitivity) or inhibition (reversible loss of sensitivity), which can be a hazard to people in the workplace.

If exposed to high gas concentrations, pellistor sensors can be damaged. In such situations, pellistors do not ‘fail safe’, meaning no notification is given when an instrument fault is detected. Any fault can only be identified through bump testing prior to each use to ensure that performance is not being degraded.

 

IR sensor

Infrared sensor technology is based on the principle that Infrared (IR) light of a particular wavelength will be absorbed by the target gas. Typically there are two emitters within a sensor generating beams of IR light: a measurement beam with a wavelength that will be absorbed by the target gas, and a reference beam which will not be absorbed. Each beam is of equal intensity and is deflected by a mirror inside the sensor onto a photo-receiver. The resulting difference in intensity, between the reference and measurement beam, in the presence of the target gas is used to measure the concentration of gas present.

In many cases, infrared (IR) sensor technology can have a number of advantages over pellistors or be more reliable in areas where pellistor-based sensor performance can be impaired- including low oxygen and inert environments. Just the beam of infrared interacts with the surrounding gas molecules, giving the sensor the advantage of not facing the threat of poisoning or inhibition.

IR technology provides fail-safe testing. This means that if the infrared beam was to fail, the user would be notified of this fault.

Gas-Pro TK uses a dual IR sensor – the best technology for the specialist environments where standard gas detectors just won’t work, whether tank purging or gas freeing.

An example of one of our IR based detectors is the Crowcon Gas-Pro IR, ideal for the oil and gas industry, with the availability to detect methane, pentane or propane in potentially explosive, low oxygen environments where pellistor sensors may struggle. We also use a dual range %LEL and %Volume sensor in our Gas-Pro TK, which is suitable for measuring and switching between both measurements so it’s always safely operating to the correct parameter.

However, IR sensors aren’t all perfect as they only have a linear output to target gas; the response of an IR sensor to other flammable vapours then the target gas will be non-linear.

Like pellistors are susceptible to poisoning, IR sensors are susceptible to severe mechanical and thermal shock and also strongly affected by gross pressure changes. Additionally, infrared sensors cannot be used to detect Hydrogen gas, therefore we suggest using pellistors or electromechanical sensors in this circumstance.

The prime objective for safety is to select the best detection technology to minimise hazards in the workplace. We hope that by clearly identifying the differences between these two sensors we can raise awareness on how various industrial and hazardous environments can remain safe.

You won’t find Crowcon sensors sleeping on the job

MOS (metal oxide semiconductor) sensors have been seen as one of the most recent solutions for tackling detection of hydrogen sulphide (H2S) in fluctuating temperatures from up to 50°C down to the mid-twenties, as well as humid climates such as the Middle East.

However, users and gas detection professionals have realised MOS sensors are not the most reliable detection technology. This blog covers why this technology can prove difficult to maintain and what issues users can face.

One of the major drawbacks of the technology is the liability of the sensor “going to sleep” when it doesn’t encounter gas for a period of time. Of course, this is a huge safety risk for workers in the area… no-one wants to face a gas detector that ultimately doesn’t detect gas.

MOS sensors require a heater to equalise, enabling them to produce a consistent reading. However, when initially switched on, the heater takes time to warm up, causing a significant delay between turning on the sensors and it responding to hazardous gas. MOS manufacturers therefore recommend users to allow the sensor to equilibrate for 24-48 hours before calibration. Some users may find this a hinderance for production, as well as extended time for servicing and maintenance.

The heater delay isn’t the only problem. It uses a lot of power which poses an additional issue of dramatic changes of temperature in the DC power cable, causing changes in voltage as the detector head and inaccuracies in gas level reading. 

As its metal oxide semiconductor name suggests, the sensors are based around semiconductors which are recognised to drift with changes in humidity- something that is not ideal for the humid Middle Eastern climate. In other industries, semiconductors are often encased in epoxy resin to avoid this, however in a gas sensor this coating would the gas detection mechanism as the gas couldn’t reach the semiconductor. The device is also open to the acidic environment created by the local sand in the Middle East, effecting conductivity and accuracy of gas read-out.

Another significant safety implication of a MOS sensor is that with output at near-zero levels of H2S can be false alarms. Often the sensor is used with a level of “zero suppression” at the control panel. This means that the control panel may show a zero read-out for some time after levels of H2S have begun to rise. This late registering of low-level gas presence can then delay the warning of a serious gas leak, opportunity for evacuation and the extreme risk of lives.

MOS sensors excel in reacting quickly to H2S, therefore the need for a sinter counteracts this benefit. Due to H2S being a “sticky” gas, it is able to be adsorbed onto surfaces including those of sinters, in result slowing down the rate at which gas reaches the detection surface.

To tackle the drawbacks of MOS sensors, we’ve revisited and improved on the electrochemical technology with our new High Temperature (HT) H2S sensor for XgardIQ. The new developments of our sensor allow operation of up to 70°C at 0-95%rh- a significant difference against other manufacturers claiming detection of up to 60°C, especially under the harsh Middle Eastern environments.

Our new HT H2S sensor has been proven to be a reliable and resilient solution for the detection of H2S at high temperatures- a solution that doesn’t fall asleep on the job!

Helping you stay safe during the BBQ season

Who doesn’t love a summer BBQ? Come rain or shine we light up our BBQs with usually the only worries being whether it will rain, or the sausages are fully cooked through.

While these are important, (especially making sure the sausages are cooked!) many of us are completely unaware of the potential risks.

Carbon monoxide is a gas that has received its fair share of publicity with many of us installing detectors in our homes and businesses, but completely unaware carbon monoxide is associated with our BBQs.

If the weather is poor, we may decide to barbeque in the garage doorway or under a tent or canopy. Some of us may even bring our BBQs into the tent after use.  These can all be potentially fatal as the carbon monoxide collects in these confined areas.

Equally with a propane or butane gas canister, we store in our garages, sheds and even our homes unaware that there is a risk of a potentially deadly combination of an enclosed space, a gas leak and a spark from an electrical device.  All of which could cause an explosion.

All of that said, BBQs are here to stay and if we use them safely, are a great way to spend a summer afternoon.  So, here is a selection of facts and tips from our safety team at Crowcon which we hope will help you enjoy a safe and delicious summer ahead!

 

Quick facts and tips about BBQ charcoals:

  • Carbon monoxide is a colorless and odourless gas so just because we can’t smell or see it, doesn’t mean it’s not there
  • Carbon monoxide is a by-product of burning fossil fuels, which include charcoal and BBQ gas
  • Always use your BBQ in a well-ventilated open area as it can accumulate to toxic levels in enclosed spaces
  • Never bring a charcoal into a tent, even if it seems cold. Remember a smouldering BBQ will still give off carbon monoxide
  • Be aware and act quickly if someone experiences the symptoms of carbon monoxide poisoning which include headaches, dizziness, breathlessness, nausea, confusion, collapse and unconsciousness. These symptoms can be potentially fatal

 

Quick facts and tips about gas cannisters:

  • Gas barbecues tend to use propane, butane or LPG (which is a mixture of the two)
  • Gas BBQs have holes in the bottom to prevent a build-up of gas. This is because gas is heavier than air so will accumulate in low areas or fill a space from the bottom up
  • To avoid the accumulation of gas, cannisters should always be stored outside, upright, in a well-ventilated area, away from heat sources, and away from enclosed low spaces
  • If you store your BBQ in the garage, make sure you disconnect the gas cannister and keep this outside
  • When you are using your BBQ, keep the cannister to one side so it isn’t underneath and close to the heat source and position the BBQ in an open space
  • Always keep the cannister away from ignition sources when changing cannisters
  • Always make sure you turn off the gas at the BBQ as well as on the regulator on the cannister, after use

 

Chernobyl – a powerful safety message to the world

The recent Sky Atlantic TV series Chernobyl sent out a powerful message about the catastrophic and far reaching consequences of radiation gases, both to people and the environment.

The series is based on true events from the 1986 nuclear disaster in the then USSR; the largest uncontrolled radioactive release into the environment ever recorded. The accident resulted in an untold number of fatalities, as well as serious social and economic disruption for large populations within the USSR and beyond.

The Chernobyl explosion resulted in a radioactive gas cloud which travelled across Europe, including the UK; falling to the ground in the form of ‘nuclear rain’.

There are many disturbing facts we read about. Not least that according to the British Ministry of Health, 369 farms and 190,000 sheep in Britain still contain traces of radioactive fallout from the Chernobyl disaster.

Both human and mechanical error contributed to the disaster and thankfully safety standards, regulations, awareness and new technologies have significantly improved since the disaster.

The principal of safety, whether a huge nuclear facility or small manufacturing plant, must remain the same. Here at Crowcon we are dedicated to keeping people and the environment protected. Our technologies support organisations across multiple industries, including nuclear plants, improving plant and personal safety. Our technologies help our customers be protected from the dangers of gases.

At Crowcon, we welcome shows such as Chernobyl which document historical disasters such as this and highlight in a dramatic but real way, the importance of ensuring companies understand the need for safety measures, however big or small, are in place.  Protecting their people, the environment and the world.

Identifying Leaks from Natural Gas pipelines at a Safe Distance

The use of natural gas, of which methane is the principle component, is increasing worldwide. It also has many industrial uses, such as the manufacture of chemicals like ammonia, methanol, butane, ethane, propane and acetic acid; it is also an ingredient in products as diverse as fertilizer, antifreeze, plastics, pharmaceuticals and fabrics.

Natural gas is transported in several ways: through pipelines in gaseous form; as liquefied natural gas (LNG) or compressed natural gas (CNG). LNG is the normal method for transporting the gas over very long distances, such as across oceans, while CNG is usually carried by tanker trucks over short distances. Pipelines are the preferred transport choice for long distances over land (and sometimes offshore), such as between Russia and central Europe. Local distribution companies also deliver natural gas to commercial and domestic users across utility networks within countries, regions and municipalities.

Regular maintenance of gas distribution systems is essential. Identifying and rectifying gas leaks is also an integral part of any maintenance program, but it is notoriously difficult in many urban and industrial environments, as the gas pipes may be located underground, overhead, in ceilings, behind walls and bulkheads or in otherwise inaccessible locations such as locked buildings. Until recently, suspected leaks from these pipelines could lead to whole areas being cordoned off until the location of the leak was found.

Precisely because conventional gas detectors – such as those utilising catalytic combustion, flame ionisation or semiconductor technology – are not capable of remote gas detection and are therefore unable to detect gas leaks in hard to access pipelines, there has been a lot of recent research into ways of detecting methane gas remotely.

Remote Detection

Cutting edge technologies are now becoming available which allow the remote detection and identification of leaks with pinpoint accuracy. Hand-held units, for example, can now detect methane at distances of up to 100 metres, while aircraft-mounted systems can identify leaks half a kilometre away. These new technologies are transforming the way natural gas leaks are detected and dealt with.

Remote sensing is achieved using infrared laser absorption spectroscopy. Because methane absorbs a specific wavelength of infrared light, these instruments emit infrared lasers. The laser beam is directed to wherever the leak is suspected, such as a gas pipe or a ceiling. Because some of the light is absorbed by the methane, the light received back provides a measurement of absorption by the gas. A useful feature of these systems is the fact that the laser beam can penetrate transparent surfaces, such as glass or perspex, so it may be possible to test an enclosed space prior to entering it. The detectors measure the average methane gas density between the detector and target. Readings on the handheld units are given in ppm-m (a product of the concentration of methane cloud (ppm) and path length (m)). In this way, methane leaks can be quickly confirmed by pointing a laser beam towards the suspected leak or along a survey line, for example.

An important difference between the new technology and conventional methane detectors is that the new systems measure average methane concentration, rather than detecting methane at a single point – this gives a more accurate indication of the severity of the leak.

Applications for hand-held devices include:

  • Pipeline surveys
  • Gas plant
  • Industrial and commercial property surveys
  • Emergency call out
  • Landfill gas monitoring
  • Road surface survey

Municipal Distribution Networks

The benefits of remote technology for monitoring pipelines in urban settings are now being realised.

The ability of remote detection devices to monitor gas leaks from a distance makes them extremely useful tools in emergencies. Operators can stay away from potentially dangerous leak sources when checking the presence of gas in closed premises or confined spaces as the technology allows them to monitor the situation without actually gaining access. Not only is this process easier and quicker, but it is also safe. Moreover, it is not affected by other gases present in the atmosphere since the detectors are calibrated to only detect methane – therefore there is no danger of getting false signals, which is important in emergency situations.

The principle of remote detection is also applied when inspecting risers (the above-ground pipes carrying gas to the customers’ premises and normally running along the building outside walls). In this case, the operators point the device towards the pipe, following its route; they can do this from ground level, without having to use ladders or access the customers’ properties.

Hazardous Areas

In addition to detecting gas leaks from municipal distribution networks, explosion-proof, ATEX approved devices can be used in Zone 1 hazardous areas such as petrochemical plants, oil refineries, LNG terminals and vessels, as well as certain mining applications.

When inspecting an LNG/LPG underground tank, for example, an explosion-proof device would be required within 7.5 metres of the tank itself and one metre around the safety valve. Operators therefore need to be fully aware of these restrictions and equipped with the appropriate equipment type.

GPS Coordination

Some instruments now allow spot methane readings to be taken at various points around a site – such as an LNG terminal – automatically generating GPS tracking of the measurement readings and locations. This makes return trips for additional investigations far more efficient, while also providing a bona-fide record of confirmed inspection activity – often a prerequisite for regulatory compliance.

Aerial Detection

Moving beyond hand-held devices, there are also remote methane detectors which can be fitted to aircraft and which detect leaks from gas pipelines over hundreds of kilometres. These systems can detect methane levels at concentrations as small as 0.5ppm up to 500 metres away and include a real-time moving map display of gas concentrations as the survey is conducted.

The way these systems work is relatively simple. A remote detector is attached beneath the aircraft’s fuselage (usually a helicopter). As with the handheld device, the unit produces an infrared laser signal, which is deflected by any methane leakage within its path; higher methane levels result in more beam deflection. These systems also utilise GPS, so the pilot can follow a real-time moving map GPS route display of the pipeline, with a real-time display of aircraft path, gas leaks and concentration (in ppm) presented to the crew at all times. An audible alarm can be set for a desired gas concentration, allowing the pilot to approach for closer investigation.

Conclusion

The range of remote methane detection systems is increasing rapidly, with new technologies being developed all the time. All these devices, whether hand-held or fitted to aircraft, allow quick, safe and highly targeted identification of leaks – whether beneath the pavement, in a city or across hundreds of kilometres of Alaskan tundra. This not only helps prevent wasteful and costly emissions – it also ensures personnel working on or near the pipelines are not exposed to unnecessary danger.

Because the use of natural gas is increasing worldwide we foresee rapid technological advances in remote gas detection in applications as diverse as leak survey, transmission integrity, plant and facilities management, agriculture and waste management, as well as process engineering applications such as coke and steel production. Each of these areas have situations where access may be difficult, combined with the need to put personnel protection at the top of the agenda. Opportunities for remote methane detectors are therefore growing all the time.

 

Explosion hazards in inerted tanks and how to avoid them

Hydrogen sulphide (H2S) is known for being extremely toxic, as well as highly corrosive. In an inerted tank environment, it poses an additional and serious hazard combustion which, it is suspected, has been the cause of serious explosions in the past.

Hydrogen sulphide can be present in %vol levels in “sour” oil or gas. Fuel can also be turned ‘sour’ by the action of sulphate-reducing bacteria found in sea water, often present in cargo holds of tankers. It is therefore important to continue to monitor the level of H2S, as it can change, particularly at sea. This H2S can increase the likelihood of a fire if the situation is not properly managed.

Tanks are generally lined with iron (sometimes zinc-coated). Iron rusts, creating iron oxide (FeO). In an inerted headspace of a tank, iron oxide can react with H2S to form iron sulphide (FeS). Iron sulphide is a pyrophore; which means that it can spontaneously ignite in the presence of oxygen

Excluding the elements of fire

A tank full of oil or gas is an obvious fire hazard under the right circumstances. The three elements of fire are fuel, oxygen and an ignition source. Without these three things, a fire can’t start. Air is around 21% oxygen. Therefore, a common means to control the risk of a fire in a tank is to remove as much air as possible by flushing the air out of the tank with an inert gas, such as nitrogen or carbon dioxide. During tank unloading, care is taken that fuel is replaced with inert gas rather than air. This removes the oxygen and prevents fire starting.

By definition, there is not enough oxygen in an inerted environment for a fire to start. But at some point, air will have to be let into the tank – for maintenance staff to safety enter, for example. There is now the chance for the three elements of fire coming together. How is it to be controlled?

  • Oxygen has to be allowed in
  • There may be present FeS, which the oxygen will cause to spark
  • The element that can be controlled is fuel.

If all the fuel has been removed and the combination of air and FeS causes a spark, it can’t do any harm.

Monitoring the elements

From the above, it is obvious how important it is to keep track of all the elements that could cause a fire in these fuel tanks. Oxygen and fuel can be directly monitored using an appropriate gas detector, like Gas-Pro TK. Designed for these specialist environments, Gas-Pro TK automatically copes with measuring a tank full of gas (measured in %vol) and a tank nearly empty of gas (measured in %LEL). Gas-Pro TK can tell you when oxygen levels are low enough to be safe to load fuel or high enough for staff to safely enter the tank. Another important use for Gas-Pro TK is to monitor for H2S, to allow you judge the likely presence of the pryophore, iron sulphide.

Servicing for safety… A visit to the oil refinery

Working in the office makes it easy to focus on the individual tasks and get detached from how our products are making a difference to people’s lives. One of our customers was kind enough to facilitate an onsite visit so that Andrea (our Halma Future Leader on a marketing placement) could see first-hand how our products are used and who the end users are. This meant a visit to an oil refinery to see where our Crowcon portable gas detectors are used.


“The main thing that surprised me was the sheer size of the site. The oil refinery was very spaced out and it took us 10 minutes to walk from the entrance of the site to where the Crowcon engineer’s based. The engineers and employees around different parts of the refinery wore Hi Vis jackets, big safety boots, hard hats and all appeared to have personal gas detectors. During a quick site tour, I learned the products of the oil refinery are not limited to gas or petrol, but also tar, asphalt, lubricants, washing up liquid, paraffin wax and much more.

The products are all stored in big containers with pipes all over the site. Most of the products are highly flammable which explains the big focus on safety. In the distance, there were a few dome shaped containers which are pressurised vessels. If one of them were to explode, it would have a 10 mile blast radius. Suddenly I had the urge to leave and drive about 10 miles.

Crowcon’s engineer base was full of orange T4s, Gas-Pros as well as an army of “Daleks”, I mean Detectives, awaiting calibration and service. While the harshness of this industrial environment was evident from their appearance, they were otherwise in good working order, and the service engineer worked through the devices quickly.

The end users think of them as a simple device they have to wear to do their job, and they like the simplicity and reliability of Crowcon devices. The Detectives get thrown around and Gas-Pros are almost black is comparison to the usual orange, which just showcases how important the robustness of our devices is. The dangers of this working environment are not generally a big concern to the users, this is everyday life to them. Our devices help ensure they go home after a tough shift. Ensuring the devices are functioning properly is down to the service engineers, and they need to think for the users to ensure that the devices are being used properly.

Seeing Crowcon’s devices being used and the number of times someone enquired if the devices are calibrated and ready to go back into action, highlighted just how important use of portables as part of the safety regime  is considered. “Quality” and “robust” is how users describe Crowcon products and even though they may now treat them like the life saving devices they are, the devices are regularly used and valued. They make a very flammable and dangerous environment a safer place to be.”

“For anyone looking to start an apprenticeship I would say go for it, as it has been a great experience for me because you get to carry out practical activities on site at Crowcon and the theory side at college on a day release type format. This is vital as it gives me the knowledge behind carrying out certain activities and it all links together with my everyday work.” Ryan Jones

 

“For someone who was interested in technology and how things work in different industries, it was inevitable that engineering would be sector in which I chose to pursue a career. However, I am also a person who wouldn’t prefer to be learning in a classroom every day. Therefore, apprenticeships allow you to work in real world environments giving the options to gain the essential experience needed for future careers choices.

Working for an established company like Crowcon provided a clear training program, both in and out of the workplace that would provide me with the skills and knowledge to progress further within the engineering industry. Given the support provided by the company I have been able to push myself in the classroom to achieve the very best. This was reflected in being awarded a variety of accolades on both local and national levels during my time here at Crowcon.”  Vikesh Patel

We’re always looking at recruiting apprentices and graduate engineers to support in achieving recognised qualifications from NVQs at Level 2 to BTECs, HNC and in some disciplines, such as finance or purchasing, post graduate or professional certificates.

Home grown talent will be the differentiator of the future. The cost of higher education is making many re-think the automatic study routes. It is no longer necessary to become burdened with a large debt, via full time study, to achieve your potential in the work place. Vocational career paths are finally becoming more widely available, with a multitude of opportunities and development routes.

People Development is at the heart of our business success and working collaboratively to release the wider potential within our business is how Crowcon will continue to go from strength to strength.

Following a successful completion of the 3 year apprenticeship, you could follow a similar path to previous apprenticeships with scope to move into an engineering role after a few years in the Line Technician position. Previous apprentices have taken roles in Test & Verification, Quality Engineering, and Manufacturing Engineering.

After all, why would you take a job, when you can have a career?

Working together for safety at sea

Crowcon Detection Instruments is working together with Solent University’s Warsash School of Maritime Science and Engineering – all in the name of teaching engineering cadets, senior Merchant Navy officers, and Superyacht crews.

Solent delivers world-renowned yacht and powerboat design degree programs, a suite of international maritime studies courses and a wide range of specialist support services for the maritime industry. It is also conducting a large number of research studies that make a real impact on industry thought leadership.

Their partnership with Crowcon makes good sense!  The marine environment is a dangerous one – and not just the more obvious hazards like high seas, storms, or rocks and coral reefs.  Confined spaces on ships, high-risk cargo, and on-ship processes all present potential gas hazards.

To keep mariners safe, gas monitoring equipment is essential.  Gas detection equipment requires specific marine environment testing and certification to ensure suitability to the extreme environments it operates in.  The European Marine Equipment Directive (MED) approval is internationally recognised. Gas detectors used by mariners onboard a vessel registered in an EU country must hold MED approval, and show the wheel mark to demonstrate compliance.

Crowcon has provided the university with demonstration T4 portable multi gas detectors.  T4 provides effective protection against the four most common gas hazards experienced in the marine industry, and is robust and tough enough to deal with the demanding marine environments.  T4 is ideally suited to help vessels comply with multiple SOLAS requirements which dictate the need for gas detection onboard vessels.

John Gouch, lecturer at  Solent University, said: “I have used Crowcon instruments in industry for many years, and know how reliable and trustworthy their gas detectors are. Since joining Warsash 18 months ago, I have been keen to ensure students understand the important part gas detection plays within the on-board safety system.”

“By using demo units of these detectors within our marine engineering courses, we can show the importance of gas detection in a marine environment to hundreds of seafarers and mariners, keeping as many people as possible aware and safe.”

Louise Early, Head of Marketing at Crowcon, said: “We’re really pleased with our partnership with Solent University.  By developing our relationship with training establishments, our safety message gets out to the people who will benefit most. We are always keen to learn from industry and this program also offers Crowcon further insight into the way in which our equipment is used.”
