2.1.1 Type of test facility

  2.1.1.1 The tests described by these Guidelines are intended to be undertaken in either a manoeuvring basin or in head and following waves in a conventional towing tank. The model may either be:

  • .1 towed from a carriage (preferably equipped with the capability for free-to-surge under constant towing force), with freedom to heave, pitch and roll; or

  • .2 self-propelled and remotely controlled, either by radio or by a lightweight umbilical attachment.

  2.1.1.2 The wave making facility should be capable of generating the requisite specific wave spectra with accuracy within + 2.5% on significant height, ±2.5% on TP, and ± 5% on TZ.

2.1.2 Scale

 The model scale should be as large as practicable with respect to the test facility employed, but the model should not be less than 1.5 m in length, and be:

  • .1 appropriate to enable the requisite full scale significant wave height to be generated; and

  • .2 capable of providing the equivalent of at least 1 min duration of operation at full scale per tank run at the maximum speed to be tested.
