Great Ships Initiative


The Great Ships Initiative (GSI) is a regional effort devoted to ending the problem of ship-mediated invasive species in the Great Lakes-St. Lawrence Seaway System and globally. Since its establishment in 2006, the primary objective of GSI has been to accelerate research, development and implementation of effective ballast water management systems (BWMSs) on board ships like those that visit the Great Lakes region from abroad. Specifically, GSI provides independent status and certification testing services to developers of BWMSs at the bench-scale, at a land-based facility, and on board ships. GSI performs status tests for BWMSs that are in the research and development stage. It is part of two US Coast Guard-certified "Independent Laboratories" capable of freshwater certification efficacy testing of market ready BWMSs.

February 2016 - GSI releases a bench-scale technical report on the effects of UV irradiation on survival and reproduction of selected protist and zooplankton species. Click here to view the report.

October 2015 - GSI hosts a “Train-the-Trainerworkshop with the International Maritime Organization's GloBallast Partnerships Programme. More

September 2015 - GSI helps the Navy Research Laboratory (NRL) and the Alliance for Coastal Technologies (ACT) test emerging ballast water compliance tools in the Great Lakes. More.

December 2014 - How Well Do Today's Ballast Water Filters Perform in Natural Fresh Water? GSI releases findings from a series of land-based tests on eight commercially-available ballast water filter systems. More.
