Draft increase

25 Oct 2021 / Torres Strait, Australia

Following trials conducted since 2019, the Australian Maritime Safety Authority (AMSA) has increased the maximum permissible draft limit for container vessels passing Torres Strait to 12.50m basis 1.025 SW density, commencing 1 November 2021.

Vessel transits of Torres Strait at drafts to 12.50m cannot be guaranteed every day whereas nearly every day there is sufficient tidal rise to allow transit windows for vessels with drafts up to 12.2M. As in the past, vessels may be required to anchor or slow down to await a tidal window that will permit a safe transit. These waiting times can vary depending on weather and sea conditions experience at that time. Vessels would also be required to proceed at slower speeds to minimise squat and ensure minimum permissible UKCs are maintained.

As a general guide, vessels can transit Torres Strait at 12.20m draft almost every day of the year. There may only be one tidal window available per day for the deeper transit and vessels may be delayed waiting for the next tidal window and therefore suggest vessel operators and Masters engage with the chosen pilotage provider early for passage planning purposes.
