JANTRAN, the river towing subsidiary of Bruce Oakley Inc., has a new harbor boat it uses to shuttle barges to and from its fleets on the Arkansas and Mississippi rivers. It is the third of three new fleet boats the firm has built for its own use since 2013. A fourth is under construction, also at the company’s shipyard in Rosedale, Miss., where the others were built.
The twin-screw vessel is named the mv. Terrene, after a landing at Mile 592 on the Lower Miss, just upstream of Rosedale. The two boats that preceded it are the mvs. Rosedale and Logloader, likewise named for places on or around the river close to Rosedale, where the company is headquartered.
At 72 feet, the new boat is 10 feet longer than the other two. It is 26 feet wide by 10 feet high, with an operating draft of 8 feet, 3 inches and a pilothouse eye level of 27 feet, 6 inches. President Joe Janoush designed the Rosedale and Logloader, and had input on the Terrene, but for the most part it was built on the design of Hayden Pearson, who is a second-generation employee.
“The Terrene is a hybrid design of the other two,” said Pearson. “I deepened the tunnels to reduce vibration, and there is none, which I think is something for a 72-foot, 2,000 hp. boat.” Another factor that he considers special is that his father is now the captain on the Terrene.
The fourth boat will be a 56-foot, 1,200 hp. harbor vessel for Oakley’s Port 33. It will be named the mv. Legacy.
“We are very proud of the construction crew here at JANTRAN,” said Leslie Jenkins, human resources manager. “It has been very gratifying to see each vessel built from the ground up. Each one is solid and well-built, and the entire crew deserves all of the credit for their hard work.”
The 2,000 hp. Terrene is powered by twin Cummins QSK38-M1 diesel engines that turn 78- by 52-inch Kahlenberg propellers on 7-inch shafts built by Mosley Manufacturing, which also built the custom packing glands. The Duramax Johnson bearings were supplied by Humco. Reduction is 6:1 through Twin Disc MG540 gears. The main engines and reduction gears were provided by Cummins Mid-South.
The engines are cooled by Fernstrum Keel Coolers, monitored by Murphy alarms and equipped with Maxim silencers. Further sound and vibration dampening is provided for by Marine Industrial Insulation. Inside the hull is tankage for 15,000 gallons of fuel, 4,100 gallons of potable water and 750 gallons of lube oil.
The vessel utilizes an electric, follow-up steering system with an electric, non-follow-up backup from Custom Hydraulic Components. Two John Deere 4045 auxiliary engines with Marelli 50 kw. generators from Engines Inc. provide ship’s service.
The crew’s quarters consist of three bedrooms with double bunks and two baths. The interior features wood tongue-in-groove walls and ceilings, oak cabinets and rubber flooring. The boat is equipped with JRJ Alum Fab aluminum exterior doors. There are two 4-ton air conditioning and heating units and one 4-ton split unit, all installed by M&I Electric.
The electronics package, which features an FR8065 Furuno radar and AIS, plus a DeHart swingmeter, was installed by Wheelhouse Electronics. On top of the pilothouse are two Carlisle & Finch joystick-controlled searchlights from Dixon Marine.
Deck equipment includes two 40-ton Wintech winches and eight LED floodlights, also from Dixon Marine. The hull is protected by laminated fenders from Schuyler Maritime.
