2 Manoeuvring Characteristics in Deep Water

Parent topic: Appendix 3 - Manoeuvring booklet

2.1 Course change performance

  2.1.1 Initial turning test results (trial or estimated, at the full load and ballast conditions), test conditions, diagrams of heading angle versus time and ship's track

  2.1.2 Course change test results (trial or estimated, at full load and ballast conditions)

 Curves of course change distance and point of initiation of counter rudder for the necessary course change angle (for both full load and ballast conditions)

2.2 Turning circles in deep water (trial or estimated, at the full load and ballast conditions)

  2.2.1 Turning circle test results

 Test conditions, test results (advance and transfer) and turning track at full sea speed ahead

  2.2.1.1 Turning circles in both full load and ballast conditions (stern track should be shown)

  2.2.1.2 The data presented should refer to the case of starboard turn only (unless there is significant difference for port turn)

  2.2.1.3 The initial speed of the ship should be full sea speed ahead

  2.2.1.4 Times and speeds at 90°, 180°, 270° and 360° turning should be specifically shown together with an outline of the ship

  2.2.1.5 The rudder angle used in the test should be the maximum rudder angle

2.3 Accelerating turn (trial or estimated)

  2.3.1 Data are to be presented for both full load and ballast conditions in the same manner as 2.2 for turning circles. The ship accelerates from rest with the engine full manoeuvring speed ahead and the maximum rudder angle

2.4 Yaw checking tests (trial or estimated)

  2.4.1 Results of the zig-zag and pull-out manoeuvre tests at the full load or ballast condition shown as diagrams of the heading changes and rudder angle

2.5 Man-overboard and parallel course manoeuvres

  2.5.1 Man-overboard manoeuvre (trial)

 Diagrams for cases of both starboard and port turns should be shown for both full load and ballast conditions

  2.5.2 Parallel course manoeuvre (estimated)

 Diagrams showing lateral shift to a parallel course using maximum rudder angle

2.6 Lateral thruster capabilities (trial or estimated)

  2.6.1 Diagrams of turning performance at zero forward speed in the full load or ballast condition should be shown, for bow and stern thrusters acting separately and in combination

  2.6.2 Diagrams showing the effect of forward speed on turning performance should be included

  2.6.3 Information on the effect of wind on turning performance should be given
