Cummins Wartsila Engines To Power New Tug

Inland Bulk Inc. will be adding a third tug to its Lake Erie fleet in a few months. The 110 x 34 ft. (33.5 x 10.3 m) vessel will be pri- marily dedicated to pushing a 10,000-ton capacity limestone barge from its quarry on Kelleys

Island, some 60 miles east to their

Cleveland facility on the Cuyahoga

River. The first tug to be built in

North America with the all new

Cummins Wartsila series of engines, the vessel is under construction at the C&G Boat Works yard in Bayou La

Batre, Ala. The boat will be powered by two

Cummins Wartsila 16V170 engines generation 2,467 hp at 1,600 rpm. The engines will drive through Reintjes WAF871 gears with a 7.087:1 reduction to turn 99-in. Kaplan propellers in 100-in. nozzles. With a molded depth of 16 ft. (4.8 m) and a draft of 14 ft. (4.2 m) the tug is designed to have a towing speed of 10 knots.

Electrical power will be provided by two Cummins 6BT 99 kW gen sets. A 277 hp Cummins CTA 8.3 liter engine will power the deck winch. Although much of her time will be spent in the open waters of

Lake Erie, she will be equipped with four flanking rudders for notch pushing the barge in the river. Naval architect Frank

Basile of Entech & Associates in

Houma, La., reports that the hull is a sistership to the Chevron

Richmond in San Francisco.

Tug Delivered to Caillou

Island Towing

Caillou Island Towing, Houma, La., recently took delivery of a like-new boat that emerged from the charred remains of a 16-yr. old hull. "We replaced ribs and hull plating," said Rory Dupre, operations manager. "We totally rebuilt the house; it's basi- cally a brand new boat."

For power, the company chose a pair of six-cylinder Cummins KTA 19M engines, turning shallow-pitched 62 x 42 in. open wheels. The 1,200 hp tug is 62 x 24 ft., and carries a full slate of

Simrad electronics in the wheelhouse, including radar, autopilot and

GPS/Loran combination. With accom- modation for six, the vessel is involved with inland rig moving and offshore pipe barge movements. She is equipped with electric deck winches for rigging face wires to push equipment and H-bitts aft for soft line towing of barges. The boat is also equipped with a pair of Cummins four-cylinder, B- series, 3.9-liter, 35 kW gen. sets.
