Rocket rig joins hydro tunnel team

WorldWatch

NORWEGIAN CONTRACTOR Veidekke took delivery of its latest Atlas Copco L2C Rocket Boomer rig in January, the firm's fifth computerised rig and the 100th L2C sold in Norway. It has been put straight to work on Veidekke's contract at the Ovre Otta hydroelectric power project.

The project comprises 15km of tunnels, with cross-sectional areas of 20m 2, 35m 2and 45m 2, and a 50m long, 14m wide and 36m high power house cavern. The 25t, 2.5m wide, two boom machine will join Veidekke's two Rocket Boomer L3Cs and Rocket Boomer 185, to carry out about 1M. m of drilling on the project.

Atlas Copco says the L2C's ABC advanced boom control system can cover 104m 2, giving a smooth and accurate tunnel profile, with 'savings in mucking and concrete lining material'.
