Ship Motions and Mooring

  • Prepared Instructional video on Parametric Rolling for P&I Club
  • Evaluated motions and accelerations of a barge to determine design loads for barge mounted crane and container securing systems
  • Assessed motions of large, deep draft vessels transiting the San Francisco Bar Channel in heavy weather to determine acceptable under keel clearances as a function of weather and sea state.

Salvage and Oil Outflow Analysis

  • Developed casualty scenarios for rapid response training exercises and consulted on damage assessments
  • Conducted ultimate strength analysis of tankers for owner to better understand residual strength in case of a casualty
  • Developed a quantitative methodology for evaluating structural designs in the case of accidental damage (D4S and PRADS 2007 papers)
  • Provided expert witness support to owner for vessel sinking

Marine Engineering

Transportation Studies

  • Conducted market and cargo volume assessments for MARAD’s American Marine Highways program (2010-2011) in order to develop vessel service and performance requirements
  • Performed study of carbon footprint and transport efficiency of Asia – U.S. container services and compared alternative route options for deliveries to the US East Coast.  Routes studied included the widened Panama Canal, Suez Canal, and US West Coast with rail across the United States.
