Results of Karistads Mekaniska Werkstad (Sweden) tests of model representing 60,000-ton dw tanker; they show -- thrust from bow thruster jet does not change with speed; however, pressure distribution on hull is changed by jet so that resulting side force and turning moment vary with ship speed; with 1500 hp bow thruster, turning moment decreases to 50% at 4 knots and increases again for higher speeds, reaches zero at 15 knots; maneuverability is greater with both bow thruster and rudder than for ship with rudder only; at 8 knots turning moment for bow thruster and rudder is 28% higher than for rudder only.
