SKYRIDERS HAS A BLAST DEPLOYING UHP CLEANING AT LARGE PETCHEM TANK Ultra high pressure (UHP) washing is a highly-effective and environmentally-friendly cleaning method using water jets to remove old coating systems and industrial dirt and contamination, without the use of potential contaminants such as detergents or grit. Skyriders washed the tank and prepared the surface and then applied a specific protective coating. 14 Leading rope-access specialist Skyriders recently deployed UHP to clean the top part of a large tank, which is exposed to the harsh elements, and therefore subject to the worst weathering, for a major petrochemical producer in Mpumalanga. The scope of work for Skyriders was to deploy UHP at 2 800 bar in order to wash the tank and prepare the surface, and then to apply a specific protective coating system. This consisted of a primer and an intermediate coating, followed by the final two coatings. “The client, which has stringent health and safety and quality standards, had a documented specification for the application that we had to adhere to rigorously at all times,” Skyriders marketing manager Mike Zinn comments. This was necessary to guarantee the integrity of the entire protective system. Major industrial customers such as petchem and chemical plants and refineries, among others, often have separate budgets for both maintenance and access. “On this specific project, for example, we were able to prove to the client that our per-square-metre rate, which is all-inclusive of both access and maintenance, represents a significant costand time-saving,” Zinn asserts. He adds that Skyriders’ holistic approach to access and maintenance generally translates into a 20% to 25% budget saving for its clients, in addition to benefits such as enhanced health and safety and guaranteed quality of any work undertaken. The traditional means of cleaning such large tanks is grit blasting, which leaves behind a residue that itself needs to be cleaned up. This sand can also pose a safety risk during the cleaning process, as the tank remains operational during maintenance so as not to impact on productivity. The high-pressure water used in UHP, on the other hand, simply evaporates. Skyriders intends to expand the scope of its UHP service offering, as this cleaning method is ideal for major industrial structures as diverse as smokestacks, silos, and storage tanks. “It is not only an important valueadded service, but is an integral part of the turnkey access and maintenance solutions we can offer,” Zinn concludes. About Skyriders Skyriders (Pty) Ltd., established in 1998, is a leader in the South African rope access industry, providing cost- and time-saving solutions to clients in the power generation and petrochemical industries who require rope access aided inspection, NDT and maintenance work to be done in difficult to reach, high-up locations.

MOBILE CO2 MEASURING DEVICE The measurement of CO2 emissions throughout industry is a critical activity. Across many industries CO2 leaks in equipment resulting from non-maintenance, mechanical damage or wear and tear can impact on the wellbeing and safety of not only employees but also on the manufacturing processes involved, for example in the food, beverage and refrigeration industries. Adding to their already extensive range of instrumentation, Greisinger, part of the GHM Group of Companies, has launched its brand new G 1910-2 and G 1910-20 CO2 mobile, handheld measuring devices. They offer benefits to the user such as a compact CO2 monitor with an integrated sensor and an optical and acoustic alarm function with a large rechargeable battery life, easy charging and a wide measuring range. “From breweries, wine presses and dispensaries to heating, ventilation and air-conditioning to energy management in buildings and use in research and education, this newly launched, compact CO2 handheld measuring device fits perfectly into the hand and can be taken anywhere. It is the most cost-effective portable device available” said Jan Grobler, Managing Director, of GHM Messtechnik South Africa. “Every mining or pulp and paper plant, for example, has to monitor the environment and this device offers a wider measuring range than usual that can reach up to 2,000 ppm in the G 1910-02 version and as much as 19,999 ppm with the G 1910-20 model. Additionally, having a calibration connection enables the customer can recalibrate the device themselves, or we can do it for them. This eliminates the need to for devices to leave the place of operation for recalibration purposes” said Grobler. The devices are equipped with benefits such as: a long-lasting rechargeable battery with very low power consumption which enables measurements over a period of 24 hours. Standard AA NiMH batteries can be used and recharged via the Micro USB connection with a standard Micro USB charging cable without the need for a special mains adaptor. The device has an easy to read display, with backlighting. The instruments have alarms for many applications in air quality monitoring, green houses, energy management. The CO2 is measured with a high-class non-dispersive infrared (NDIR) sensor via an opening at the instruments head. The display of the time-weighted average over eight hours (TWA) or 15 minutes (STEL) can be read simultaneously. Grobler added “CO2 is dangerous at a concentration of >3%, these new portable instruments of CO2 monitoring are ideal for warnings of moderate but non-dangerous levels. They offer an impressive price/ performance ratio and a high durability as has come to be expected with German precision manufactured instrumentation”.
