Halter Marine Delivers The Point Liberty To Point Express Halter Marine, Inc., of New Orleans, La., recently delivered the Point Liberty, the third of four 191-foot tug/supply boats to Point Express, Ltd., of Mor- gan City, La. The Point Liberty is 191-feet long with a 40-foot beam and a 14-foot depth. She is powered by two EMD 16-645C diesel engines developing 1,950 hp each at 900 rpm. They drive two, 90-inch- diameter four-bladed propellers through Lufkin RHS 2120 re- verse/reduction gears with a ra- tio of 3.0:1. The vessel's six Smatco tanks each carry 1,000 cubic feet of bulk mud and four additional tanks carry 1,344 barrels of liq- uid mud. Dry mud is moved through the system by a Gardner Denver WCG air compressor and liquid muds are pumped by Mis- sion Magnum pumps. Some of the Point Liberty's other capacities are: 61,000 gal- lons of fuel oil; 1,824 gallons lube oil; 165,400 gallons ballast water; and, 16,888 gallons of fresh wa- ter. Her aft deck has nearly 4,000 square feet of cargo space. There are two Westinghouse equipped control stations aboard and a 56-point engine alarm sys- • tem provided by EMI. The hy- draulic steering system was man- ufactured by SSI. The vessel's maneuverability is enhanced by a Bird-Johnson model 20 bow- thruster driven by a Detroit Die- sel 8V71 diesel engine through Capitol reverse/reduction gears. The main switchboard and distri- bution panels were built by Con- tinental Electric. Auxiliary power is supplied by two Detroit Diesel 8V71-N die- sel engines generating 125 kw.
