Boswell Underwater Engineering has been providing waterfront and underwater inspections/investigations for PANY/NJ in the New York Harbor on a continuous basis since 1989.

Over this period of time, Boswell has developed an excellent reputation for providing reliable and high-quality services. To date, Boswell has worked effectively and expediently on more than 350 assignments for the PANY & NJ, many of them concurrent and often requiring the fielding of four inspection dive teams during a single workday. More than 150 of these assignments involved quality assurance diving inspections during marine construction to assess the contractor’s compliance with contract documents. The majority of the services provided involved condition surveys of waterfront facilities such as piers, wharves, bulkheads, relieving platforms, and ferry terminals comprised of timber, steel, concrete and composite structural members. Thirty of these projects entailed both statistical random sampling and judgment sampling techniques to assess the full extent of biodeterioration caused by marine borer intrusion of timber structures. Core sampling techniques were used to assess the level of Teredo infestation.
