Lean, Innovative, and Unique Project Solutions

Cianbro was able to mobilize and complete this project 10-weeks ahead of the original completion date in order to help support a change in the schedule for the arrival and overhaul of another vessel in the adjacent dry dock. The Cianbro team took this challenge head-on starting on September 2nd, 2002 and completed this aggressive project on August 9, 2003; ten weeks ahead of the original schedule. All this was accomplished while working through one of the coldest winters on record for the state of Maine.
