Power Take-Off (PTO) Clutches - Oil and Gas Applications

By Ed Gallucci
October 11, 2016 Category: Oil Gas, Power Take Off (PTO) Clutches Oil And Gas Applications

In this Oil Gas vehicle application, the Logan SAE 600 series Direct Drive PTO is mounted on a typical 2-pad live PTO pump pad, sandwiched between a CAT 3412 Diesel Engine and an Allison 8900 Series Transmission. The Logan 600 series Direct Drive Power Take-off (PTO) clutch will connect or disconnect the single and tandem pumps mounted to the live PTO pump pad. The pumps are used only on the job site, and remain disconnected(via the Logan PTO) when the vehicle is idle and not in use, or when driving to and from the job site. This option to clutch-in and clutch out the pumps minimizes wear and tear on the pumps, reduces unnecessary fuel consumption, and the chances of over speeding the pumps (since they are disconnected from the drivetrain) when the vehicle is at highway speeds during transport.

Western Towboat Company Inc. is a family-owned business operating 19 tugs from its base in Seattle, Washington. The tugs regularly tow rail, container, general cargo and bulk aggregate barges to Alaskan ports. Western has also undertaken tows to the Hawaiian islands, Panama Canal, the US Gulf and east coasts, and South America. The company prides itself on providing customers with one of the most modern tug fleets on the west coast. Each tug features a design that originated at Western Towboat and was built by Westerns own craftsmen. Ed McEvoy, fleet port engineer, contacted Logan Clutch when he was informed that an azimuth thruster clutch assembly he had already installed in two other boats was no longer available for a new boat under construction. I had worked successfully with Logan in the past on a winch clutch replacement project and so I decided to contact Logan for this project too, he explained. Logan engineers went to work with the goal of designing an assembly that improved

Flywheel Mounted Logan PTO Replaces Mechanical on Tug

When Canadian towing and barge services provider Island Tug and Barge encountered problems with the mechanical clutch system on one of its tugs, it turned to Logan Clutch to provide a solution. Island Tug, based in Vancouver, British Columbia, offers towing and barge services, including ramp-equipped deck barges, aggregates and general cargo, as well as cable installations. The companys towing services extend to the Pacific Rim, and it also has facilities on Canadas eastern seaboard. Island Tug had been running two generator sets on the tug Island Scout. These ran pumps for the main hydraulics and bow thrusters off the back of the engines. In order to do this, both engines were equipped with conventional, mechanical lever actuated PTO clutches to drive the pumps. The problem was that these clutches started to fail during full rev/min engagement. Generator sets normally run at 1,800 rev/min and cannot be slowed down to allow for clutch engagement. These failures were creating frequent

Logan CH 1050 series clutches proved to be just what was needed when New York-based Reinauer added fast and maneuverable articulated tug and barge units to its fleet. Reinauer Transportation Companies, based in Staten Island, New York, is a leader in the US maritime petroleum and chemical transportation business. Established in 1923 by Bert Reinauer, the company successfully weathered the Depression and the war years, and has continued that trend through the past several decades. In the 1990s, Reinauer demonstrated that it could adapt to the stringent regulatory changes imposed by the Oil Pollution Act of 1990, completely revamping its fleet by moving forward with innovative double-hulled vessel designs. These innovations manifested themselves in the form of articulated tug and barge (ATB) units, of which there are now a total of 17 in the Reinauer fleet. The most recent series of ATBs added to the Reinauer fleet were delivered by Senesco Marine, of North Kingstown, Rhode Island. There

Founded in 1889, Seattle-based Foss Maritime offers a complete range of maritime services and project management to customers across the Pacific Rim, Europe, South America and around the globe. With one of the largest fleets of tugs and barges on the American West Coast, Foss operates two shipyards and offers worldwide marine transportation, emphasizing safety, environmental responsibility and high-quality service. Logan Clutch is proud to have been involved with the conversion of the Dolphin Class tug Campbell Foss into the Worlds second Hybrid Tug. The Campbell Foss was built in 2005 in Rainer WA in the Foss Yard and was originally a conventional tug powered with two 2540hp Caterpillar 3512C engines coupled to Rolls-Royce US205 fixed pitch azimuth thrusters. The conversion involved adding a new Logan LCT Bell Housing clutch on to the 21 flywheel output of the 3512s with an integrated Centa torsional coupling. The flange output of the clutch was connected by a shaft to the motor generators
