Amazing process and a staggering amount of money per metre too no doubt. Well done to work in those conditions.The maintenance crews in that cold that keep all machinery up and running w the knowledge spare parts etc must be one hell of a job.This looks like it could have been a good video if it hadn't been for the background music.First of all congrats to all the Crew and Team members they had done good job, here i have one ? how many days they had taken to complete the job of 2.00km Pipe Excavation,jointing,Lowering & Back filling
