R.E. Derecktor Delivers Tug To Great Lakes Dredge & Dock Co.
The Hoosier State, a twin-screw 556-horsepower tug, was recently completed by R.E.
Derecktor and Co., Dania, Fla., for the Great Lakes Dredge & Dock Co. of Chicago, 111.
Designed by S.L. Petchul, Inc., Naval Architect, Ft. Lauderdale, Fla., the Hoosier State is now in operation in south Florida serving as a dredge tender. The hull has a length overall of 46 feet, a 16-foot beam, and a draft of 6 feet 6 inches fully loaded.
Power is supplied by two 8V-71 diesel engines with 4.5 to 1 reduction gears and 52- inch-diameter four-bladed stainless-steel propellers.
The basic arrangement provides control both from the pilothouse and a fly-bridge station located on top of the pilothouse. A combination electric stove, refrigerator, and sink unit is provided in the pilothouse, along with suitable seating in the forecastle for dredge crew transfers.
The hull is heavily built with 5/16-inch side plate, 5/16-inch and 3/8-inch bottom plate, 4-inch by 3-inch by 5/16-inch angle frames spaced 18 inches center to center, and 7/16-inch bent plate fenders. The fuel capacity is 2,800 gallons, with 100 gallons of potable water carried in an aluminum tank.
Equipment includes radar, radiotelephone, hydraulic steering, potable water pressure set, hand and electric bilge pumps, dirty oil pump and dirty oil tank, engine room blower, skin cooling, and a 20-kw a-c diesel generator.
Designed for heavy towing, the Hoosier State has proven to be an efficient tug with excellent handling characteristics.
S.L. Petchul reports that recent activities have included providing detail engineering plans to shipyards on their new construction projects, stability studies and calculations for U.S. Coast Guard certificated passenger vessels, along with providing the service of assisting shipyards in the preparation of labor-material estimates for vessels they are bidding. For this latter activity, extensive current material pricing information is kept on file.
Plans have also recently been provided to the Caddell Drydock & Repair Co., Inc., Staten Island, N.Y., for a completely new designed 46-foot twin-screw tug with 350 horsepower using two 6-71 diesel engines, with 4.5 to 1 reduction gears, for power.
Propellers will be 48-inch diameter, fuel capacity is 4,000 gallons, and draft of hull is 6 feet 3 inches. The tug is to be used for shipyard service.
