Linhares
Brazil, Linhares

A large-scale pipeline project was implemented in Espírito Santo, a State on Brazil’s southeast coast. Two pipelines of 77 kilometers in length were installed close to the city of Linhares to transport liquid gas and naphtha from a refinery to the port. The construction company chose to use Herrenknecht HDD equipment to cross the Monsaras and Rio Doce rivers.

A Herrenknecht HK250T HDD rig was used to lay the two parallel, eight-inch pipelines underground. It had already successfully installed pipelines with a total length of 19.5 kilometers in the Amazon Basin in Brazil, as part of the Urucu-Manaus pipeline project. Despite difficult geological conditions, it also proved its worth near Linhares. The first two 1,505-meter-long crossings were completed in just eleven days.

Thanks to daily performances of up to 530 meters, subsequent crossings, each of 1,701 meters in length could also be completed in a remarkable time – only 15 days. And the project overall was brought to a rapid and successful end. The expensive, complex and dangerous transportation of gas and gasoline by truck is now a thing of the past.
