Program Number

20.819

Program objective

MARAD will use the projects results and data for a variety of purposes including to further the current efforts that address the curtailment of aquatic invasive species within the Chesapeake Bay and coastal waters throughout the United States as associated with ballast water operations of commercial shipping.

Additional program information

  1. 2016

    The three facilities are continuing their work with conducting verification and certification testing of ballast water management systems. Also, collaborating with the USCG and RDC for verification of variable fluorescent fluorometers for ballast water compliance monitoring. The goal of the project is to determine what portable tools can be used by inspectors when conducting a compliance inspection. A specific aquatic species of concern is not an issue as the focus is on the USCG ballast water numerical standard. The geographical area is not specific; in this case the effort will be conducted in brackish and other water determined by the University of Maryland Center for Environmental Science and the Naval Research Lab. Work also continues on hull husbandry research; bio-fouling of ships’ hulls is another source of non-indigenous species entry into the ecosystem. The facilities are also conducting shipboard ballast water technology certification tests.

  2. 2017

    Verifying ballast water monitoring tools, testing ballast water management systems, surveying hull bio-fouling, recommending changes to USCG testing protocols vis-à-vis un-hatched eggs and phytoplankton characteristics.

  3. 2019

    Developed a methodology for evaluating the efficiency of technologies to remove and capture “heavier” bio-fouling from ships’ hulls.

  4. 2022

    one ballast water treatment system, award of a sub-contract for a shipboard installation of a ballast water treatment system for real-time testing over a variety of challenge conditions, development of test plans for risk-based mesocosm tests of Great Lakes water, development of a data base that contains water conditions at selected Great Lakes Ports

  5. 2023

    Finalized and released Guidelines for Testing Ship Biofouling In-Water Cleaning Systems Completed the first diver biofouling surveys on the M/V Cape Wrath (in Baltimore, MD) for the Armbach/Greensea fully-autonomous, proactive in-water cleaning system Completed a year of monthly sampling of water at the Dundalk Ro/Ro Terminal (Baltimore, MD) to understand the variability in levels of antifouling coating metal (e.g., copper and zinc), microplastics, and basic water quality parameters (e.g., total suspended solids, particle size distributions) in port waters as a result of commercial ship activities. Data is now being assembled and analyzed. Published 3 peer-reviewed papers related to marine biofouling/bio-security Completed an ISO standard on test protocols for independent evaluations of ballast water compliance monitoring devices; preparing to trial the completed standard protocols. Initiated the effort to develop ISO guidelines for testing ship biofouling in-water cleaning systems

  6. 2024

    Cooperative agreement awarded which will advance the use potential of ballast water reception facilities in the United States Great Lakes region by initial development of designs for equipment needed to interface between two Great Lake vessel types and a port-based ballast water reception facility.
