More recently, DLBA and WFM collaborated to outfit the barge with a Manitowoc 4100W Ringer Crane with 220ft boom, and eight Flexifloats. Using DLBA’s proprietary crane barge analysis routine, DLBA and WFA produced the US Army Corps of Engineers EM 385-1-1-required Naval Architecture Analysis, and designed and engineered the ringer support frame using finite element analysis. The DLBA team is excited to see this 180 x 60 x 10 foot barge out on the water, working on the historic Dry Dock 4 project and supporting our US Navy.
