Wind and Current Forces Acting on Canadian Forces Ships During Tug Operations

Abstract

This report presents predictions of wind and current forces on Canadian Forces ships during towing operations. Longitudinal and transverse forces are treated as functions of incident flow direction. For the ship geometries considered, transverse forces arising from transverse flows are much greater than longitudinal forces from longitudinal flow. For winds or currents from the bow quarter (45degrees), transverse forces are much greater than longitudinal forces. The report includes tables of wind and current forces acting on HALIFAX, IROQUOIS and AOR ships. In an operational context, the greatest errors in force predictions will likely be due to errors in wind or current velocities.
