Plant installation

The professional installation of plants, equipment, machines and systems is a decisive factor in the industry. With our experts, we work to ensure smooth commissioning and trouble-free operation of your plant.

We are specialized in the creation of what are known as Mechanical Execution Concepts which enable us to apply our many years of expertise in a time and cost-efficient manner for our customers at an early planning stage.

We have decades of experience in various industries, including the chemical and pharmaceutical industry, power plant and mechanical engineering as well as in the new industries associated with the energy transition, such as battery production, hydrogen and CCUS.


In industrial processes, temperature control is very important. Tracing, or heat tracing, ensures that products and raw materials remain at the required temperature level for optimal process conditions. The petrochemical-, food-, offshore- and other markets contain pipes, storage tanks, pumps and instruments filled with liquid products and semi-finished products. Through tracing, the desired temperature is controlled. Bilfinger has broad and in-depth expertise in both steam tracing and electrical tracing. In combination with our insulation services, we can achieve optimal process conditions.

Our knowledge and experience are important pillars for a perfect and future-proof design and implementation. We work brand-independently and can therefore always put together the right tracing system for you. Thanks to a well-considered design, your installation will meet all requirements, be user-friendly, safe and require minimal maintenance costs. We are also happy to help you think about energy-saving opportunities. For example, through smart electronic control and uniform engineering 

With the expansion of tracing methods (electric, steam, hot oil, water) and of the types of pipes (carbon steel, copper, stainless steel), tracing remains a craft. That is why Bilfinger has created an Evaluation and Training Center Tracing.

Steam tracing

Steam tracing involves using hot steam to bring the pipe to the desired temperature. Where steam is available, or where high power is required from tracing in a customer's production process, it is the most energetically logical to use steam to keep the production process at temperature.

Electrical tracing

Electrical tracing works by means of conductive cables lying around the installation and giving off heat through electrical resistance. Electrical tracing always offers a solution in the absence of steam and has a wider temperature range than steam.

Services for rotating equipment

From manufacturer-independent consulting and maintenance to ongoing optimization and repair, Bilfinger offers comprehensive services throughout the entire service life of rotating equipment. We monitor ongoing operations and guarantee process safety and maximum reliability. This service package is complemented by a large rental pool that includes 20,000 pieces of equipment consisting of pumps, drive motors and frequency converters.

High availability, time efficiency, cost savings

Pumps, reciprocating compressors and turbomachinery are at the heart of many production plants. They convey liquid or gaseous raw materials as well as process industry end products and ensure they are in constant motion. Because they generally operate around the clock, they are significantly responsible for the availability and economic efficiency of process industry plants.


Bilfinger Rotating Assessment

With the Bilfinger Rotating Assessment (BRA), we help our customers develop risk-based and sustainable maintenance for their rotating equipment. BRA is a tool for identifying optimization potential and recommending measures to reduce costs and improve availability.
