Many organizations in the maritime industry do not have an administrative staff. The Exchange, therefore, provides support services for the Pacific Merchant Shipping Association (PMSA), the Puget Sound Harbor Safety Committee (PSHSC), the Washington State Maritime Cooperative (WSMC), and the Puget Sound Marine Firefighting Commission (PSMFC). The functions for PSMFC include a federal grant through the Port of Seattle to develop a model Marine Terrorist Response Plan. The services for all of these organizations include invoicing and accounting, coordinating meetings, and maintaining membership lists and meeting records.
The Exchange also manages and operates the West Seattle mooring buoys on behalf of BUOYS-R-US. This includes taking reservations, maintenance and billing for use of the buoy system, which is primarily used by the tug and barge industry.
