How FPT Industrial engines power the world’s longest immersed tunnel project

The Fehmarnbelt tunnel, a colossal project that will connect Denmark and Germany across the Baltic Sea, is being built with the help of FPT Industrial engines. The brand of Iveco Group, specialized in advanced propulsion technologies, has supplied its F36 Stage V engines for power generation to CGM, a leading producer of gensets. These gensets, distributed by Bimotor S.p.A., are currently in operation at the massive Fehmarnbelt construction site, which includes the largest concrete factory in the world.

The Fehmarnbelt tunnel, co-financed by the European Commission and due for completion by 2029, will be the world’s longest immersed tunnel with a length of 18 kilometers. It will consist of 79 standard and 10 special elements, each measuring 217 meters long, 42 meters wide and 9 meters high, and weighing 73,500 tons. The tunnel will contain two tubes for motorway, two for railway and a service passage. The tunnel elements will be fabricated at a nearby factory, then towed by tugs to the installation site, where they will be lowered into a trench dredged on the seabed and connected together.

The construction of the tunnel requires a significant amount of reliable, ready-to-use energy, and the project has entrusted this to the CGM gensets powered by FPT Industrial engines. The F36 engine, which meets the Stage V/Tier 4F emissions standards, features high performance (up to 100 kVA PRP at 50 Hz) and high efficiency. The engine comes in an integrated solution, with cooling pack and air cleaner pre-installed on the engine, and with a preassembled and pre-validated ATS, offering fast, simple installation. The engine also boasts best-in-class service interval (600 hours), one-side serviceability, hydraulic tappets and lifetime ATS, allowing for minimum maintenance costs and maximum uptime.

The Fehmarnbelt tunnel will offer the quickest and most direct route between Scandinavia and Central Europe, reducing the travel time across the Femern Belt to 10 minutes by car or 7 minutes by train, compared to today’s 45-minute ferry crossing. It will also benefit the environment, as it will reduce CO2 emissions and free up capacity on roads and railways. FPT Industrial is proud to be part of this monumental project that will enhance the European transport network and aligns with its commitment to sustainability.

The following table summarizes some of the key features and benefits of the FPT Industrial F36 engine for CGM’s gensets:

Feature Benefit
Stage V/Tier 4F compliant Low environmental impact
High performance and efficiency Adequate power and fuel economy
Integrated solution Easy installation and integration
Long service interval and lifetime ATS Reduced maintenance and downtime
