Waging a 'Blind, Underwater Battle'


BALTIMORE—Scores of highly trained divers wielding specialized marine equipment are preparing to embark on a near-blind mission to save the rotting infrastructure below the massive Port of Baltimore.

In a 440-day, $8.9 million maintenance project detailed by The Baltimore Sun, the elite teams will plumb "zero visibility" waters as they work to replace timber and concrete structures below the port's piers, said Terry Clarke, president and owner of Marine Technologies Inc., the Baltimore-based contractor that will carry out the project.

The work targets timber structures from the 1920s and concrete structures from the 1930s, The Sun reported in a front-page feature Friday (April 17).

Above the work, global shipping traffic at the nation's second-busiest port will continue uninterrupted.

The report details the planning, training and equipment—from floating cranes to decompression tanks to low-light underwater video—being mobilized to execute the highly specialized, and very dangerous, round-the-clock project.
