  • Tab 1: Seaway-Sized Bulk Carrier Model for Hydrodynamic Optimization of Ballast-Free Ship Design Click to Download
    Michael G. Parsons and Miltiadis Kotinis, University of Michigan
    The current research focuses on the design of a typical Seaway-sized bulk carrier and the construction of a scaled model to be utilized in subsequent towing tank experiments. A major part of the initial hydrodynamic analysis that was performed on the modified LASH vessel was based on the ship-specific Computational Fluid Dynamics (CFD) code SHIPFLOW ® [Flowtech Int. 1998], which has been shown to have significant limitations regarding the prediction of the important viscous flow near the stern. In the current research, the external flow around the Ballast-Free bulk carrier has been investigated numerically using FLUENT ® [Fluent 2005]. These external flow results have been utilized to obtain the necessary boundary conditions for numerical simulation (also in FLUENT ®) of the water flow in the longitudinal ballast trunks. The internal flow was simulated in order to estimate the flow rate scaling factor needed in preparation for the subsequent towing tank experiments.

    Peter S. Lindquist, Ph.D., and Mark A. Vonderembse, Ph.D., University of Toledo
    This project marked the beginning of a long-term endeavor to develop and manage a comprehensive data repository and information clearinghouse for the maritime industry in the Great Lakes. The system is envisioned to facilitate the acquisition, storage, management, analysis and exchange of data between analysts and decision makers within the industry. This system will thus serve as a resource for public policy decisions and for drawing the necessary link between maritime freight movements, economic viability, and environmental quality throughout the Great Lakes and St. Lawrence Seaway. As such, the system will serve as a central focus for diverse interests within the industry to support the promotion of sustainable maritime transportation in the region.
  • Tab 3: Tax Systems and Barriers to Great Lakes Maritime Commerce Click to Download
    Randall K. Skalberg and James A. Skurla, University of Minnesota Duluth
    This project inventories the tax impact on the Great Lakes marine transportation system imposed by federal regulations. This project also identifies the unique tax burdens placed on the commercial maritime regulatory process in the Great Lakes, and presents an analysis of the Great Lakes maritime tax structure focusing on its most significant tax, the Harbor Maintenance Tax (HMT). Finally this project discusses possible changes to the current tax structure to improve the efficiency of port maintenance tax collection and expenditure, and to improve intermodal transportation fuel efficiency.
  • Tab 4: Alternatives to Petroleum Based Fuel for Marine Vessels Click to Download
    Abu R. Hasan, Daniel Pope, James A. Skurla, University of Minnesota Duluth
    This project was proposed in two parts: The first part presents engineering aspects of biodiesel fuel use for maritime commerce. This alternative fuel can be used as renewable energy in current diesel engines. The literature suggests that biodiesel fuel has similar energy content to diesel and little impact on performance; the fuel has better lubricity than petro-diesel and it compensates for Ultra Low Sulfur Diesel (ULSD); and that biodiesel can use the current distribution infrastructure, with some modifications for cold weather. It is also noted that biodiesel biodegrades faster than petro-diesel, and produces reduced emissions. Part two follows this chapter and offers an economic impact analysis.
  • Tab 5: Feasibility Study: Usefulness of Modern Acoustic Methods to the Maritime Industry in Relation to Changes in Water Depth in the Great Lakes Click to Download
    Steven M. Colman and R. Douglas Ricketts, Large Lakes Observatory (LLO), University of Minnesota Duluth
    This project is a feasibility study to determine whether state-of-the-art acoustic imaging techniques, used in basic scientific research studies, can be applied in a way that is useful to the maritime industry. It addresses Great Lakes Maritime Research Institute (GLMRI) focus area “Marine transportation and port environmental issues,” and the specific research topic “Great Lakes Outflow Investigation” listed in the call for proposals.
  • Tab 6: Great Lakes Maritime Transportation K-12 Education Program for Teachers, Students and Communities Click to Download
    Joan Schumaker-Chadde, Michigan Technological University
    This project addressed the GLMRI Focus Area of K-12 public education and outreach programs. The project conducted two one-week teacher institutes in summer 2006, developed an interactive online web module for students, a K-12 Maritime Transportation Education website and a K-12 teaching trunk. A total of 21 K-12 teachers attended the two teacher institutes. They were extremely enthused about their experience and are now excited to teach about Great Lakes shipping in their classrooms. Thousands of students and others in the Great Lakes basin and nationwide will be reached in the coming months and years via the new lessons developed by the teacher participants, or by interacting online with actual photos and real-world challenges of Great Lakes maritime transportation through an interactive web module, website, and teaching trunk.

Inland Waterways LNG Stakeholders Meeting, St. Louis, Missouri

The Great Lakes Maritime Research Institute (GLMRI) in conjunction with and support from the Maritime Administration, Department of Transportation, hosted a meeting of stakeholders to discuss the possibilities of using Liquefied Natural Gas (LNG) as a marine fuel for the inland waterways".

Third annual meeting on regional Liquefied Natural Gas (LNG) potential held May 21st

LNG experts discussed LNG uses and the safety culture along with their experiences as current users. The afternoon panel highlighted the potential benefits of using LNG, themed "greening the supply chain". More details here.

Meeting to Discuss Base Local Demand and Siting for an LNG Liquefaction Plant

Potential LNG fuel users from mining, agricultural, trucking, rail and maritime sectors met to determine if there is sufficient base load demand within a 200 mile region to warrant development of an LNG liquefaction and fuel transport, storage and distribution network centered in Duluth/Superior. Work continues to consider siting and determine supply chain demand. Presentations from the meeting
