Wind and wave investigations

These studies involve floating Light, Detection and Ranging (LiDAR) equipment which is a remote sensing technology used to determine wind speed, direction and other atmospheric variables like temperature and pressure.

A wave buoy is used to understand waves, tides, water levels, currents and sea surface level temperature.

These investigations support planning and design of the offshore windfarm including maximising energy capture.

Environmental surveys

These surveys are carried out to identify and understand plants and animals present in the study area such as marine mammals and birds.

This data can be used to identify ecologically sensitive habitats and populations and will support development and design of the windfarm.

Geophysical investigations

Geophysical investigations are carried out by vessels to gather information such as the composition and features of the seabed including significant habitat and any pre-existing objects such as cultural heritage, shipwrecks etc.

Geotechnical investigations

Geotechnical investigations are conducted to assess the seabed geology such as rock layers, and are carried out by specialised vessels and drilling units.

Geotechnical data will help inform windfarm components such as the type of turbine foundations to be used.

These types of investigations require authorisations and approvals under the Environment Protection and Biodiversity Conservation Act 1999 (Cth) and/or Offshore Electricity Infrastructure Act 2021 (Cth).
