Description: Technical note
PURPOSE: This Coastal and Hydraulics Engineering Technical Note (CHETN) summarizes the Ankudinov empirical formula for ship squat predictions used by the U.S. Army Engineer Research and Development Center(ERDC) Ship Tow Simulator (STS). This CHETN documents the Ankudinov squat formulas and describes two FORTRAN programs that were written for single and multiple ship speed applications. Two examples are given for a Panamax bulk carrier and Panamax tanker for both programs. A companion CHETN compares and validates the Ankudinov squat predictions with laboratory measurements of a Post-Panamax containership and field measurements of a Panamax containership, tanker, and bulk carrier in the Panama Canal. It also compares the Ankudinov formula with several of the Permanent International Association of Navigation Congresses (PIANC) empirical squat formulas.
