The crane barge, Jams M. Keen, was built at Conrad Shipyard in Morgan City, Louisiana. The barge measures 110
feet, 6 inches by 60 feet with a molded depth of 8 feet 6 inches. In addition to barge construction, Conrad will
also install two government‐supplied cranes – a wicked lifter crane and a telescoping marine crane.

The barge is used to raise and lower the steel dam wickets and perform maintenance functions at the Olmsted Lock and Dam on the Ohio River.

To ensure crew safety, StableHeat was hired to install radiant heating beneath the open deck to prevent ice and snow buildup during inclement weather.
