The Barossa project will require various offshore support vessels during operations. The nature of the offshore support will be:

1) Crew Boat

A crew boat is required to take up to 20pax between Darwin Port and Subsea7 Vessels at anchorage. The vessel will be needed during offshore operations between Q1-Q3 2024, and again in H1 2025.

Crew transfer of up to 6 or 12 pax is also expected between Heavy Lift Vessels and Subsea7 Construction Vessels anchored both within port limits and ~3km outside port limits. The vessel will be needed for 3 periods of approximately 4 days each where it will complete 1 run to/from the vessel every 12hrs.

These 2 requirements can be met by the same vessel or separate vessels.
