3 Stopping and Speed Control Characteristics in Deep Water

Parent topic: Appendix 3 - Manoeuvring booklet

3.1 Stopping ability

  3.1.1 Stopping test results (trial)

 Test conditions, ship's tracks, rpm, speed, track reach, head reach and side reach

 Two or more tests should be carried out including a test of full astern from full sea speed ahead and a test of full astern from full ahead speed

  3.1.2 Stopping ability (estimated)

 Information and diagrams should be given of the track reach, head reach, side reach, time required and track reach deceleration factor (distance/one knot reduction) of a ship in both full load and ballast conditions covering the following modes of stopping manoeuvres:

  • full astern from full sea speed ahead
  • full astern from full ahead speed
  • full astern from half ahead speed
  • full astern from slow ahead speed
  • stop engine from full sea speed ahead
  • stop engine from full ahead speed
  • stop engine from half ahead speed
  • stop engine from slow ahead speed

3.2 Deceleration performance (estimated)

  3.2.1 Deceleration ability (estimated)

  • Information and diagrams should be given concerning the track reach, time required and deceleration factor of the ship in both full load and ballast conditions for the following engine orders:

    • full sea speed to “stand by engines”
    • full ahead to half ahead
    • half ahead to slow ahead
    • slow ahead to dead slow ahead

3.3 Acceleration performance (estimated)

  3.3.1 Information and diagrams should be given for track reach and time for the ship to achieve full sea speed ahead, from zero speed
