Volume Three Appendix 12 Appendix 12 Determination of Wave Energy 1. Wash Rule 1.1 Means a Maximum Wave Energy of 9 kilojoules per metre, which may be exceeded no more than once in 10 sequential Wave Records. The sequence of Wave Records need not be contiguous where instrument or system failure or presence of non-calm conditions or missed passage of ships would make any particular Wave Record unusable or unavailable. 2. Technical Information to be provided with applications for consent 2.1 To demonstrate that a ship will comply with the Wash Rule, resource consent applicants must submit technical information prepared by a competent professional based on either: 2.1.1 Accepted and properly calibrated computational models, physical models, analytical or empirical analysis allowing for the specific characteristics of the ship concerned and all the relevant operating conditions, navigation tracks, physical effects and conditions within the National Transportation Route; or 2.1.2 Direct measurements specific to the ship concerned covering relevant operating and physical conditions; or 2.1.3 Combinations of the approaches outlined above. 2.2 Wave Energy must be calculated according to linear wave theory (also known as Airy wave theory), as outlined further below, based on the maximum zero down-crossing wave height and the corresponding zero down-crossing wave period in any Wave Record, as defined further in IAHR (1989). 2.3 Wave Energy must be determined at a standard depth of 3 metres for sites at which, in the opinion of a competent professional, are not significantly influenced by the effects of diffraction due to bathymetry and objects. 2.4 Applications for consent must include information detailing the following: (a) The Data Recording Device(s) intended for recording ship navigation details; (b) The intended format, mode of transmission and frequency of transmission to the Council of data recorded by the Data Recording Device(s) including any proposed protocols or arrangements for access to the Data Recording Device(s); (c) The intended format, method and location of storage of data generated by the Data Recording Device(s) that is held by the consent holder as archived information including any proposed protocols or arrangements for access to that archived information; (d) The intended maximum Ship Speed through the National Transportation Route including spatial definition of any areas of the National Transportation Route within which maximum Ship Speed is to be varied; App 12 – 1
