Damen's DACS to Boost Fuel Efficiency of Amisco's Cargo Vessel
Damen Shipyards has secured the first order for its Damen Air Cavity System (DACS) with the system set to be installed on a cargo vessel owned by the shipping company Amisco. Damen has developed DACS to support maritime operators in their efforts to reduce fuel consumption and emissions."DACs is an air lubrication system, borne out of a collaboration between Damen and the Delft University of Technology (TU Delft). It maintains a thin layer of air over the flat bottom of a vessel’s hull, reducing resistance in the water, thereby lowering drag and friction.
INSIGHTS: Lorry Wagner, Ph.D., President, LEEDCo
Dr. Lorry Wagner has served as president of the Cleveland-based Lake Erie Energy Development Corporation (LEEDCo) since May of 2010.LEEDCo is the public private partnership behind the effort to construct Icebreaker Wind, a 6 turbine 20.7 megawatt offshore wind energy demonstration project in Lake Erie, 8 miles off the shore of Cleveland. LEEDCo has received funding from the U.S. DOE under its Advanced Technology Demonstration Projects award and has partnered with Fred. Olsen Renewables of Norway. Dr.
Eco-friendly Power for Container Ships in Hamburg Port
Port of Hamburg is taking a further step toward improving air quality at its port. Innovative technology developed right here in the city is set to enable large and very large container ships to switch off their auxiliary diesel supplies during lay time and instead draw the power they need for on-board operations from a new kind of mobile generator.Becker Marine Systems, Hapag-Lloyd AG and Hamburger Hafen und Logistik AG (HHLA) have been testing the new technology as part of a joint pilot project since the start of the year. Technology supplier Becker Marine Systems developed the mobile power generator, then partnered with Hapag-Lloyd and HHLA for the test phase.
WRRDA: Clearing the Channel for P3 Projects
Earlier this year, the U.S. maritime industry in general, and the inland waterways industry in particular, celebrated the long-awaited passage of the Water Resources, Reform and Development Act of 2014. Among the accomplishments of this legislation were provisions to address the funding needs of the ever-worsening condition of the inland waterways infrastructure. Among these provisions are Sections 2004 and 5014 of WRRDA. Of the two provisions, the public-private partnership (P3) pilot program under Section 5014 has received substantially more attention in the maritime press and at industry conferences than have the studies of federally tax-exempt bonds and potential sources of additional revenue for the IWTF under Section 2004.
ABB HPT Turbochargers Taken Up by MAN
ABB Turbocharging's high-pressure tuning (HPT) has been added to MAN Diesel & Turbo’s two-stroke marine diesel engine tuning options. HPT is a new engine tuning for part and low loads designed to fully leverage pressure ratio and turbocharger efficiency, two critical factors in a turbocharger that are often not used to their full potential. HPT forces more air into a two-stroke engine by increasing the pressure 0.5 bar above what would normally be expected from the turbocharger. Most turbocharging setups for part and low load require some extra hardware such as an exhaust gas bypass (EGB) or variable turbine geometry to reduce excess pressure from the cylinders.
