Model experiments were conducted in a towing tank to determine the fully appended powering predictions for a preliminary design of a Salvage Ship (ARS-46) fitted with stock propellers. Powering predictions for the ship going astern and for the ship in bollard-pull and towrope-pull conditions are presented. The results of a wake survey experiment performed in the plane of the propeller disk are presented. The harmonic analysis of the circumferential distribution of the longitudinal and tangential velocities are also presented. (Author)
