Repower News

Louisiana-based Cheramie Marine's offshore support vessel (OSV) Mary Cheramie has been refitted with a pair of new Mitsubishi engines, power solutions provider Laborde Products announced.The vessel's two new Mitsubishi Tier 3 S12R engines, each delivering 1,260 HP at 1,600 RPM, replace the older Caterpillar 3512 engines.According to Laborde Products, the new engines' fully mechanical design simplifies maintenance and operation while enhancing reliability and reducing emissions.

Laborde Products announced the completion of a repower project for the towboat Ned Merrick, owned by Canal Barge Company. The project featured the replacement of the vessel's previous engines with two Tier 3 S16R engines from Mitsubishi, each delivering 1,675HP at 1,600RPM.The 145-foot-long twin screw retractable towboat was previously powered by two EMD 567 engines. It was built by Southern Shipbuilding Corp., Slidell, La., in 1961.David Lane, Senior VP with Canal Barge Company…

Campbell Transportation Company has repowered one of its towboats, the M/V Louise S, as part of an ongoing effort to modernize its fleet and enhance operational efficiency.The vessel, a 150-foot-long triple screw towboat built in 1968, was previously powered by three EMD 12-645 propulsion engines. Its new Tier 3 Mitsubishi S16R-Y3 engines, provided by Laborde Products and each outputting 1,675 horsepower, bring the total vessel power to 5,025 horsepower, significantly enhancing the boat's capability and efficiency.

Scania was selected by Allen Marine Tours to power a pair of their eco tour vessels. The two 78-foot QUAD powered vessels will each be repowered with Scania V8 DI16 082M, 800 HP engines delivered by Cascade Engine Center. The custom-built catamarans are capable of 30 plus knots at their full capacity of 150 passengers, and speeds in excess of 35 knots with a lighter load.“We have seen a lot of interest in our V8,16-liter engines by tour operators in ecologically sensitive areas like Alaska due to their low environmental impact…

“We got 59,115 hours on those engines, without ever removing a head,” says Seaspan International’s Port Engineer Kevin Tweedy, “And they were still running. So, at 5,000 to 5,500 hours per year, we could easily have done 60,000 hours.”But the company schedule worked to do a like-for-like repower. The pair of 850-horsepower Tier 1 Cummins KTA38 diesels were pulled out, and a brand-new set of 850-horsepower Tier 2 KTA38s went in.The Seaspan Cavalier was built in 1974, along with three sister ships.

Ocean science is in high demand by scientists studying ocean acidification, wave energy, seabed composition, changing water temperatures, fish populations and dozens of other research projects. The Oregon State University (OSU) has a proud history in the field. The wide variety of research project require a variety of vessels.One boat that has made large contributions to research is the 54 by 16.5-foot Elakha which was built in 2001 at Rozema Boat Works of Mount Vernon Washington.

Dutch start-up Skoon Energy and the Port of Amsterdam have launched a floating battery service to bring mobile stored power into the port and inner city of Amsterdam.According to a release from the sea port, the battery, which is placed on a barge and powered by local, renewable energy, will help balance the electricity grid. Because it is placed on a barge, the battery can deliver electricity anyplace close to water.Skoon operates a platform that enables mobile battery sharing to optimize the economics for battery owners and user. This concept of battery sharing facilitates all services for energy users who are in temporary need of electricity.In April and May, the number of river cruise calls is at its peak, due to the flower field season.

As sometimes happens with boats in the maritime world, the recent repower of a tug shone a light on a pair of well known independent companies. The tug Gretchen H. (ex Harry Olsen, Polar Breeze) was built by Rodriguez Shipbuilding of Coden Alabama in 1997 and is currently owned, since 2005, by Boyer Towing.The Gretchen H is a good solid boat and her owners decided she was well worth a new set of engines. At 80 by 30 feet she has an eleven foot depth. As with many tugs out of the Rodriguez yard she has triple propellers and triple engines. She had an older set of engines rated at 700 HP each.
