NEWBUILDING HOPPER BARGES

Project Summary

For the construction of 3 new 4,500 ST dwt inland hopper barge at the Gunderson Yard in Portland, OR, Argonautics Marine

Engineering, Inc. provided Owner's Representation. At irregular intervals, the yard was visited to monitor progress and inspect the

construction quality. Meetings with the yard's internal QA inspectors were held to review their findings. Final detailed hull surveys

were conducted before and after each launch. The first barge was successfully delivered in November 2007. The second barge was

delivered in March 2008, followed by the third and last barge in January 2009.

After the launch and delivery of each barge, trip & tow surveys were provided.
