Baptism and start of southbound TBMs

15 Nov 2016

The two southbound Follo Line Tunnel boring machines were baptised Tuesday 15th of November by Project Manager Anne Kathrine Kalager from Jernbaneverket. Simultaneously one of the two machines started its journey towards Ski.

Two of the four machines have already commenced boring northbound towards Oslo. Now the journey begins for the two southbound machines, with the TBM "Anna from Kloppa” first in line. In early December, the second southbound TBM, "Magda Flåtestad", will start boring.

- Thanks to good cooperation, good planning and considerable effort from AGJV the project is on track and tunnel boring in direction Ski can start as planned. We look forward to having all four TBMs boring simultaneously, says Anne Kathrine Kalager, Project Manager TBM.

- We are now starting the southbound excavation with the third TBM. So far the boring is ahead of schedule and productivity is as expected, hence we are very pleased with the progress. The main focus is always safety first. Other key factors are to maintain productivity and enhance logistics, maintenance routines and productivity. Our success factors include a good collaboration with Jernbaneverket, good planning, innovation and a strong team with great international knowledge and experience, says Fernando Vara, Project Director for Acciona Ghella Joint Venture.

Four machines
A total of four tunnel boring machines will excavate and construct the main part (18,5 km) of the 20 km long tunnel between Oslo and Ski, a tunnel which will be the longest railway tunnel in the Nordic countries when it is completed in 2021. So far the two northbound machines are on schedule, and have bored respectively approximately 660 m and 370 m tunnel.
