Key Lakes Shipping operates gigantic ore boats on the Great Lakes. The largest of these is 1,000 feet and regularly carried thousands of pounds of iron ore and other materials. Trident was asked to automate the ballast system so crew members could adjust ballast remotely from tablet PCs rather than walking up and down seven flights of stairs from hold to the pilot house. First, engineers had to automate a manual system for the barge, then enhanced it with wireless controls. Now the system can be controlled quickly, easily and accurately.
