LR III.6 Fatigue Design Assessment

  LR III.6.1 ShipRight FDA. This notation (Fatigue Design Assessment) may be assigned upon request when an appraisal has been made of the fatigue performance of the hull structure in accordance with the ShipRight FDA procedures.

  LR III.6.2 ShipRight FDA plus. This notation (Fatigue Design Assessment plus) may be assigned upon request when an appraisal has been made for a higher level of fatigue performance than that made for the assignment of ShipRight FDA. The appraisal may be made based upon a specific trading pattern, which is to be expressed in terms of either a Worldwide trading route, as defined in the ShipRight FDA procedure, or a North Atlantic trading route (that utilises the wave data from IACS Recommendation 34). The notation ShipRight FDA plus is to be followed by the number of years that the vessel has been assessed for the specific trading pattern for either the Worldwide or North Atlantic trading routes denoted by WW and NA respectively, e.g. ShipRight FDA plus (25, NA).
