The Great Lakes St. Lawrence Seaway Development Corporation (GLS) is conducting market research to identify qualified sources for the ABS special periodical survey drydocking of the towing vessel M/V Seaway Guardian. The work requires drydocking for hull and load line surveys, followed by wet lay berth time for additional ABS surveys and trials, with a performance timeframe of one month. Interested shipyard firms must be located within a 500-mile radius of Massena, NY, and demonstrate specialized experience in ABS surveys, past drydocking projects, and capacity to complete the work. The response deadline for submissions is May 18, 2026, and firms should submit a capability statement with three similar projects completed in the last three years. No budget information is specified in this notice.
