Vessel displacement
The auto tune process (autotune) should be performed with the vessel loaded midway between light and
loaded displacement. Once in service, optimal JETanchor control performance occurs at the vessel
displacement used during autotune.
Weather and sea conditions
Autotune should be performed in relatively calm weather and sea conditions. As a general guide, auto tuning
is most likely to be successful and produce good quality results if wind speed is less than 10 knots and current
is less than 0.5 knots.
Note that some autotune tests require the vessel to be placed in a specific orientation with regard to wind or
current direction. Autotune is unlikely to be successful if weather and sea conditions cause significant vessel
pitch or roll when the tests are running.
