Gulf Coast Trailing Dredge Under Construction At Twin City Shipyard

Construction of a 4,000-cubic-yard hopper dredge is progressing on schedule at Twin City Shipyard (TCS) in St. Paul, Minn. The 8,000- bhp vessel for Gulf Coast Trailing Company of New Orleans is being designed and constructed by TCS using the latest modular and zone construction methods.

TCS is using state-of-the-art, computer-aided drafting and steel fabrication programs. Modules weighing up to 125 tons are fabricated and assembled in the yard's large erection hall, moved out by hydraulic walkers, and lifted into place using a heavy-lift Ring Horse crane (photo).
