Crane Barge

The Shearer Group, Inc. (TSGI) designed a 200' x 72' x 14', ABS-classed floating crane barge, the OCEAN RANGER. The barge was built by Metal Trades, Inc., of Yonges Island, SC. Additional engineering for the crane boom and back-leg foundations and associated equipment was provided by TEEARC Engineering of Henderson, NV. The barge is certified at 500 short tons lifting and capable of being certified at 700 short tons lifting. Allowable deck loading is 3200 pounds per square foot. The boom was originally built by Manitowoc and installed on the ocean service crane barge CHEROKEE. It was refurbished and installed on the “OCEAN RANGER” by Stevens Towing. The OCEAN RANGER is equipped with a ballasting system to allow minimum trim when making lifts. The mooring winch is a diesel-driven Clyde Frame 8. The hoist winches are Skagit Model RB-90. The Shearer Group worked with Stevens Towing and TEEARC to analyze the operating requirements and maximum utilization of the vessel.
