The hopper dredge Frederick Paup made history when it entered service in early 2026. At 419 feet 10 inches long and 81 feet wide, she is the largest U.S.-flagged, self-propelled hopper dredger built in American maritime history. This latest addition to Manson Construction’s fleet is purpose-built to maintain and improve the navigability of waterways and harbors, something most of us never notice but which is essential to global shipping and supply chains. And while corrosion protection is critical for any working vessel, it’s especially important—and made more challenging—considering the singularly abusive conditions in which dredgers operate.
