Tenneco’s Marine SCR Gets DNV GL Classification
Tenneco, a leading global supplier of Clean Air after-treatment technologies, has been awarded two approved in principle (AIP) certificates for its high horsepower selective catalytic reduction (SCR) system from DNV GL, one of the world’s leading classification societies and a recognized advisor for the maritime industry. The certificates cover key components of the system, including the complete dosing and control system, injectors, load sensors and the human machine interface (HMI) remote monitor, as well as catalyst and reactor hardware configurations for IMO Tier III applications. “We’re pleased to receive this important classification.
Emissions Control Takes Center Stage for Workboat Engines
Today’s workboat operators must navigate increasingly stringent IMO and EPA environmental and emissions regulations in and around ports and rivers. As the drama unfolds, selective catalytic reduction or SCR is emerging as a viable vehicle to do just that. At the same time, fears about space constraints for smaller vessels and the hassle of carrying and handing urea for these systems are rapidly evaporating, as well. Two different firms – both familiar names in propulsion markets – have embraced SCR as the way forward. Both, Tenneco and Volvo Penta, rely on deep roots in these markets and significant experience in the effort to reduce emissions from engines.
Tenneco, Texas A&M Partner on Emissions Solution
Sea trials, training and scholarship program designed to educate students on clean air technologies. Tenneco, a global supplier of Clean Air aftertreatment technologies is helping engineering midshipmen at the Texas A&M Maritime Academy learn firsthand how advanced aftertreatment technology can help diesel engines meet new emissions regulations while efficiently and effectively powering the ships of the future. Midshipmen received hands-on experience this summer with Tenneco’s latest large engine selective catalytic reduction (SCR) diesel aftertreatment technology on the TS General Rudder, which is operated by the Maritime Academy. Midshipmen helped conduct field tests during their training cruises in the Gulf of Mexico to demonstrate how the system’s form…
Tenneco SCR System Receives ABS PDA Certificate
Tenneco has been awarded three product design assessment (PDA) certificates from the American Bureau of Shipping (ABS) for its new selective catalytic reduction (SCR) system for large engines. The PDA certificates cover key components of the system, including the complete dosing and control system, injectors, load sensors and the human machine interface (HMI) remote monitor, as well as catalyst and reactor hardware configurations for both EPA and IMO applications. Tenneco’s SCR…
New Large Engine SCR Systems Debuts at Workboat
Tenneco (NYSE: TEN) has announced that it has introduced a complete urea dosing control, fluid handling and catalyst solution for selective catalytic reduction (SCR) aftertreatment, enabling large engines to meet EPA Tier IV and IMO Tier III regulations. The company will showcase the complete system at the 2014 WorkBoat Show in New Orleans, Dec. 3-5, 2014 (Booth #2152). The system is designed specifically for high-horsepower engines in the marine, stationary and locomotive markets, providing precise and reliable delivery of liquid urea.
Gevo Supplies Test Fuel to USCG
Gevo, Inc. has begun supplying the U.S. Coast Guard R&D Center with initial quantities of finished 16.1% renewable isobutanol-blended gasoline for engine testing. “Gevo’s proprietary isobutanol-blended gasoline is truly a drop-in fuel, deliberately designed to be fully compliant with marine fuel specifications, including fit-for-purpose properties,” said Patrick Gruber, Gevo’s chief executive officer. The U.S. Coast Guard R&D Center is using the Gevo-blended fuel as part of a 12-month, long-term operational study on marine engines that began during June. The testing is being performed under a Cooperative Research and Development Agreement (CRADA) between the U.S.
Caterpillar’s Marine Center of Excellence
Highly automated, fully variable assembly process allows Cat to provide uniform service to a myriad of marine customers. But, MCOE is only one part of Cat’s new business strategy. In August of 2007, the first Cat marine engine left Caterpillar’s new Marine Center of Excellence (MCOE) in Greenville, South Carolina. In the ensuing years, countless engines have gone through the same process. Caterpillar Marine Power Systems brings together all the sales and service activities for Cat and MaK branded marine products within Caterpillar Inc. The organization provides marine power solutions (high and medium speed with outputs from 11 kW to 16,000 kW) and customer service from a single source for the global ocean-going, commercial and pleasure craft markets.
