A.H. Beck was involved in a project replacing an old launch rail system in the shipyard "LaShip" in Houma, Louisiana.
The project was to design, demolish, and replace the existing launch rail system within Edison Chouest Offshore Companies’ largest shipyard, LaShip in Houma, Louisiana. The launch rail system was experiencing differential settlement during vessel fabrication and launch. The old launch rail system was completely replaced and the launch transfer bulkhead hinges were retrofitted to isolate the launch system from the adjacent bulkhead structure. The ground improvements consisted of a series of paired Grout Columns along the entire length of both launch bays, a total of 1070 LF of rail system.
Applied Foundation Testing provided load-testing capabilities to verify required capacity of the Grout Columns. The retrofitting of the transfer hinges consisted of installing high capacity Post Grouted Drill Shafts. All work was performed as vessel fabrication and assembly continued within the facility.
