Construction work on the largest suspension bridge to span the Danube River and connect two regions of Romania began in 2018. The massive project, stretching almost 2 km, represents an important step forward in connecting the regions and improving the quality of life of inhabitants, who were previously dependent on a ferry to cross from one side of the river to the other.

Through its distributor, All Generating, Himoinsa has supplied 15 gen-sets providing more than 8 MW of power for construction of this major road linking Braila and Tulcea Counties and forming part of the Buzau-Constantia highway. The gen-sets powered the extraction pumps used to lay the bridge pillars and anchorages and the welding equipment used to secure all the metal parts of the bridge framework.

During the first phase of the project, Himoinsa supplied more than 4 MW of power to operate the water extraction pumps located both on the anchorages and on the central pillars of the bridge, one of which has been erected on an artificial island in the Danube.

To extract water from the first anchorage, a 1 MW containerized gen-set was installed; in the second anchorage, three gen-sets providing a total power supply of 1.5 MW were deployed. Both anchorages measure 40m in diameter and are 23m deep.

During the second phase, model HFW 600 T5 gen-sets mounted on slow-speed, four-axle trailers were supplied, generating almost 4 MW of power and running at least 20 hours per day for a minimum of three months. One of the requirements of the project was that the controller could monitor the generators via GSM for geolocation purposes and for parallel synchronization, if necessary. Attached to the gen-sets is a switchboard that connects the numerous welding equipment used during the construction of this infrastructure.

According to Catalin Stanciulescu, general manager at ALL Generating, “Our end customer has been very positive about the compact size of our generator sets with high-capacity tank we installed to increase the running time of the equipment and reduce the need for refueling, thus reducing the risk of contaminating the river. Another positive factor was the chassis which we designed to retain any possible spillage of liquids inside the canopy itself.

“The performance and responsiveness of the equipment, Himoinsa and All Generating’s know-how, as well as the quality of the generator sets are the reasons why our equipment was chosen for this project.”
