24 Apr 2018 / Port Botany, Australia
By direction of the Harbour Master, notwithstanding the draft requirements stated in the Harbour Master’s Directions, the movement of sea going vessels entering and departing Port Botany are restricted under certain sea and swell conditions.
When swell conditions are greater than 3 metres at the Port Botany Channel entrance, a formula is used to calculate maximum permissible Draft. This formula is based on a minimum depth of 15.6m in the shipping channel entrance at Botany Bay.
Max. Permissible Draft in Metres = (15.6 + height of tide – max. swell at the channel entrance*) ÷ 1.1
Note: Maximum swell shall be the swell at the *Bombora Wave Buoy or the *Captain Cook Channel Wave Buoy, whichever is the greater.
The above formula is used as a guide for calculating the transit draft, however, the final permissible Draft is determined by the Pilot of the inbound/outbound vessel at Botany, at the time of arrival or departure.
Mariners, port users and persons in charge of vessels are advised to plan their arrival and departures from Port Botany accordingly.
