Welcome to Cal Maritime's Golden Bear Facility (GBF)

The GBF is a dedicated United States facility onboard the Training Ship Golden Bear that is available for your organization's testing and certification needs.


The GBF is a Cal Maritime and US Maritime Administration partnership that has created the first of its kind testing facility. GBF is a Research, Development, Testing and Evaluation (RDTE) facility aboard Cal Maritime’s 500-foot Training Ship Golden Bear. Available year round, the GBF is truly a unique environment for testing ballast water management systems to international and United States Coast Guard (USCG) standards. Our team’s primary focus is to evaluate the mechanical and biological efficacy of these systems in a real, onboard, environment.
