Measuring skids for technical losses

Measuring skids for technical losses


The Serbian Oil Industry (Gazprom Neft) oil and gas field stations have only recently been refurbished to meet the most complex production processes. All facilities include a wide range of energy consuming devices such as heavy fuel and gas boilers, steam heaters, glycol dehydrators and compressors. Most of the systems are fueled by natural gas from the gas fields. In order to control the energy efficiency of each of their gas field stations, the company decided to monitor the natural gas consumption of their systems, as well as to detect technical losses due to soot formation in burners.


This project consisted of design and delivery of the project documentation, equipment supply, installation and start-up of the System for Measurement of Technical Losses and Own Gas Consumption in all oil and gas field plants. Given the volatile parameters of the medium, it was required that temperature andpressure measurement were included as a part of the solution. ATEX zones 2 Ex d ia approvals were also mandatory.

The solution included Krohne Vortex flowmeter OPTISWIRL 4070C installed on over 70 measuring skids, with integrated pressure and temperature compensation, thereby prevailing over solutions with turbine meters, rotary gas meters or multivariable transmitters as offered by competition. The instruments were mounted on bypass lines to allow easy dismantling without process interruption. The majority of these lines were meant to be part of a permament system of piping with different nominal sizes from DN 15 to DN 100 (classes 150 lb, 300 lb and 600 lb). Flowmeters with sandwich process connection were used at these measuring sites. Five other flowmeters were fitted at mobile metering systems that allow for a temporary flow measurement at 14 varying measuring sites. These flowmeters were installed with flanges.

Standard measuring skid consists of:

  • vortex flowmeter,
  • pressure gauge,
  • temperature gauge,
  • bypass ball valves.

Customer benefits

Main customer benefits on this project include:

  • better and more accurate overall bilance for their own consumption and technical losses,
  • integrated pressure and temperature compensation,
  • same technical solution for all 48 oil and gas stations,
  • unique staff training for maintenance,
  • unique spare part list,
  • easier maintenance.

Project Details


Our automation & control solutions range from conceptual design to start-up and commissioning and include control system configuration & integration, safety control systems, remote instrument enclosures (RIEs) & panels enclosure and panels design and traditional automation & control services combined with advanced applications offerings and field construction services

WIG offers an independent approach to vendor selection and application.

Our vendor-independent approach allows us to objectively assist in the selection process of the major controls in order to maximize operating efficiency and productivity. Also, as an engineering company, we have the internal knowledge and resources necessary to offer our clients turnkey solutions, from concept to commissioning and startup. Our extensive project management experience, paired with a structured implementation approach and early involvement in the project, can significantly reduce rework and associated costs later in the project.

WIG is one of the leading providers, in this part of Europe, of automation & control services, including system engineering, specification, integration and implementation.

Experience matters. We have built a reputation for innovation, quality and value through skillfully engineered automation & control systems to the upstream oil & gas as well as, water&wastewater, food and beverages and refining and chemical industries. We deliver projects to customers schedule, managing multiple and diverse technologies, automation, maintenance and business system integration and lifecycle costs.

We in WIG are fully aware that commissioning usually represents a critical stage in the life of a facility. Commissioning process may be considered as a series of vital checks undertaken before actual operation begins. Since the complete commissioning services play an important role in minimizing project risks and achieving performance goals from the very start, our job is to prove the integrity of all systems, identifying and correcting design and construction errors along the way. Our comprehensive approach helps our clients meet a host of challenges; regulatory, safety and environmental compliance; and naturally, operational performance.

We in WIG undertake complete responsibility for commissioning, whether we start in the engineering office, provide expertise in the fabrication yard or mobilize to a remote area.

Our confidence and wide range of options are the result of support and cooperation we have been cultivating for more than 20 years with our Principals and Partners.

We also promote products and represent our principal's interests with an accent to provide comprehensive customers support in instrumentation selection and application, consulting, distribution of products and systems created by our principals and partners. After that stage, we take care of long term genuine spare parts supply and provision of technical documentation and manuals, software tools for operating and maintenance and many other customer related aspects.
