GM-Powered Towboat 'Jeanie-K' Delivered By Riverway Shipyard

Riverway Shipyard Company, Grafton, 111., recently completed construction of the 1,200-bhp towboat Jeanie-K (shown above) for Riverway Harbor Service, New Orleans. The new vessel will be used as a fleet boat and a shuttle boat in the New Orleans area.

The Jeanie-K is 65 feet long, 24 feet wide, and 10 feet deep.

She has an operating draft of 8 feet. The bow rake headlog and corners were built of %-inch plate with %-inch rub bars welded over the corners for added protection.

The towknees, headlog, and rigging deck were outfitted with rubber bumpers from B-J Marine Products. The rigging deck is also outfitted with a Class C-3 LOHED car puller.

The boat was built with a fully equipped galley, internal stairs, two bathrooms, quarters for six crew members, an e l e c t r o n i cs room, and a 9-foot by 10-foot pilothouse with a 26-foot eye level.

The main stack is removable for easy access to the engine room.

The two General Motors Detroit Diesel Allison main engines were furnished by Western Diesel Services. They are model 16V92, each rated at 600 bhp at 1,800 rpm. They are air operated from the pilothouse by AMOT air controls.

The Twin Disc reverse-reduction gears turn the shafts at 7:1 ratio, and were also supplied by Western Diesel. The stainlesssteel, four-blade propellers are 72-inch diameter by 64-inch pitch.

They were fitted to two 6-inch t a i l s h a f t s with three chrome sleeves each.

The two steering rudders and four flanking rudders have 6-inch stocks with upper and lower mild steel sleeves. The sleeves turn in brass bearings lubricated by grease. The steering and flanking rudders are individually controlled by double-acting hydraulic cylinders. Power and control to the cylinders is supplied by a two pump/motor combination of v a r i a b l e volume furnished by Skipper Hydraulics, Inc. Complete control of the motor operation is handled from the pilothouse.

Electric power is derived from two Detroit 3-71 diesels operating at 1,800 rpm driving 3-phase, 30- kw International Electric generators.

One generator is air start; the other battery start. Voltage is reduced to proper operating levels by transformers through a Simplex modular control system.

Compressed air for engine starting, engine controls and whistle is supplied by two Quincy air compressors with 5-hp, 1,800 rpm motors.

A Pan American Systems Corporation's 18-point monitoring and alarm system maintains a constant check on main and auxiliary engines and miscellaneous, associated equipment in the engine room. A pilothouse information panel provides auxiliary monitoring signals.

Deck machinerv includes two NABRICO hydroelectric 40-ton winches. Fire protection on the boat is provided by the standard r e m o t e l y operated fire pump hooked directly to two hose stations on the exterior of the vessel.

The interior is fully protected by manually operated portable C02 fire extinguishers.

The pilothouse, crew quarters, galley, and two bathrooms are fully insulated for heat, air-conditioning, and sound. The boat is air-conditioned for comfort. A St.

Louis Ship FAST System LS-1 was installed for treatment of sewage.

A Carlisle & Finch 500-watt xenon searchlight and two Carlisle & Finch 14-inch, 1,000-watt incandescent searchlights are located on the pilothouse roof. Directional spotlights are located on all four corners of the vessel at the second deck level. The pilothouse is fitted with a Kahlenberg airhorn and radar manufactured by Furuno.
