Lewa has delivered a total of six Ecoflow type LDH5 process diaphragm pumps to the Arabian Gulf in order to expand the pumping capacity of two offshore gas fields. The pumps are used to inject mono ethylene glycol (MEG) to prevent bore hole icing at critical points along the pipeline. This job follows two earlier major projects. As part of the largest job in Lewa’s history, a total of 40 process diaphragm pumps for MEG injection were built for the end customer, an international company, in 2013. A follow-up order in the summer of 2017 included the delivery of 12 Ecoflow series type LDH5 pumps, among other products. The experience, gained on the two previous projects has helped to handle the current, third project with even more speed and efficiency.

The major order arrived at the end of March 2018. Its goal was to increase the pumping capacity of two offshore gas fields in Saudi Arabia. For this purpose, an international oil and gas company ordered a total of six Ecoflow type LDH5 process diaphragm pumps from Lewa. They are installed on wellhead platforms (WHPs) together with the corresponding M8 pump heads. From there, the pumps will inject mono ethylene glycol into the pumping process. This will prevent methane hydrates from accumulating at critical process locations, thereby effectively countering bore hole icing. “The six LDH5 pumps work with an operating pressure of approximately 520 bar and are designed for a flow rate of 5000 l/h,” said Klaus Figgle, Senior Project Manager of Engineering at Lewa. “As such, they are ideally suited for the application and contribute to complication-free gas pumping.”

As part of the cooperative effort with the end customer, this current major project represents what is now the company from Leonberg, Germany’s third MEG-injection project for the Arabian Gulf gas field. The shipment of 40 process diaphragm pumps back in 2013 (as part of what was previously the largest order in Lewa’s company history) was supplemented in 2017 by the follow-up order of 12 process pumps and 8 boxer pumps. The company received the letter of intent for the current project Lewa in May 2018, and the contract followed in July 2018.  “Since the previous order involved the delivery of identical systems, we completed the project promptly and efficiently by November of the same year,” Figgle reported. “We were even able to shorten the delivery process of the first two systems by three weeks. The customer has expressed a high level of satisfaction with both the quality of the pumps and the course of the project.” The systems are currently being installed on the platform.

AR solution in the App Store
Augmented reality app enables 3D interior view of pumps

After the augmented reality app (AR) from LEWA, the Leonberg, Germany-based pump manufacturer , attracted lots of attention at the Achema 2018 and Hannover Messe 2019 trade shows, the range of applications is now being expanded. The app was originally intended for use during trade shows only, but it is now being offered to all interested users as a free download from the Apple App Store as of July 2019. After the AR app was launched at the leading trade fairs mentioned above, Lewa received many inquiries from customers and interested parties concerning individualized options for use. “The level of interest in the app and the frequent inquiries surprised us, since the program was originally developed to improve the visualization of the mechanics of our pumps at trade fairs,” reported Thomas Bökenbrink, Lead Product Manager Pumps at Lewa. The AR solution was further developed for Hannover Messe 2019 to display the model of an Ecoflow process diaphragm pump in the new LDZ drive size with three different pump heads on a tablet, and show how the pump can be freely positioned within virtual space. Using ground plane detection, the tablet’s camera detects the floor of the relevant room and positions the model inside the room on the screen. The pump can be viewed from all directions and viewing angles, and clearly shown thanks to the 3D depiction of the complex inner structure of the pump. The model is also freely scalable, enabling the size of the pump to be adapted to the available space. In addition, the app can animate pump operation and its behavior in exceptional situations.

“With pump visualization, we have the ideal virtual training and trade show exhibit. We can also imagine using in the service and maintenance segment to better explain the functions of the pump based on the virtual model,” said Bökenbrink as he explained the versatile app’s options. In the first version, available in the Apple App Store as a free download under the name “orange showroom,” the model of the Ecoflow process diaphragm pump in the new LDZ drive size is initially available for virtual viewing. The app runs on all Apple iPads with iOS 12.0 or later, the app is not available on the iPhone. Lewa is planning to successively add other pump types in the application. “To us, our AR app represents a big step forward with regard to the simple, clear visualization of our products. It enables us to always have our pumps on hand and produce them as a digitally savvy way to explain our pumps based on their virtual representation,” Bökenbrink summarized.
