About this file
This document is a weight estimate for an 888-B115-01r1 150' x 38' x 10' deck barge. The weight estimate includes details on the structure, outfitting, and other components of the barge, with estimates for the weight, center of gravity, and moments for each subgroup. The total lightship weight is estimated at 914,328 lbs or 408.18 long tons, with a VCG of 6.54 ft. Margins are included for construction and design. This weight estimate appears to be supporting a federal contract opportunity for the procurement of three (3) welded steel deck barges to support the civil works mission of the U.S. Army Corps of Engineers' Detroit District. The principal dimensions, delivery location, and other high-level requirements for the barge procurement are outlined in the related federal contract opportunity.
