  • Project Name
    HydroScheme Industry Partnership Program (HIPP) Lord Mayor Shoal to Pitt Shoals Hydrographic Survey
  • Duration
    24 September 2023 – 02 December 2023
  • Client
    Australian Hydrographic Office, Australian Government
  • Location
    Lord Mayor Shoal to Pitt Shoals, Western Australia
  • Scope of Work
    MMA Offshore will perform a hydrographic seabed mapping survey off the coast of Lord Mayor Shoal to Pitt Shoals, along the inshore route through Lacepede Channel towards Cape Leveque and King Sound for the purpose of updating nautical charts to improve navigational safety. Activities will include:
    • Multibeam bathymetry and backscatter acquisition
    • Deployment and recovery of tidal infrastructure and current meters (offshore)
    • Installation of geodetic infrastructure (onshore)
    • Seabed sampling
    • Sound velocity profiles
    • Bioluminescence observations
    • Water clarity observations
    • Sea surface temperature
  • Survey Area
    Approximately 212 square nautical miles (approximately 393km)
  • Vessels
    • Third-party project vessels “Empress” and “Outer Limit”
    • Smaller vessel “Empress” will conduct 12-hour daylight survey works in shallow water
    • Primary vessel “Outer Limit” will pre-install GNSS buoy moorings, current meter frames and barometer buoys under 24-hour operations in non-shallow areas
    • Survey Speed 7 knots for both vessels
  • Equipment
    • Multibeam Echo Sounder
    • Subsea Tide Gauges (TG)
    • Subsea Current Meters (CM)
    • Oceanographic Tide Buoys

As part of the HydroScheme Industry Partnership Program (“HIPP”), MMA Offshore was awarded the contract to undertake the Lord Mayor Shoal to Pitt Shoals Hydrographic Survey by the Australian Hydrographic Office (“AHO”) on behalf of the Australian Government. The purpose of the hydrographic survey is to facilitate the safe navigation of domestic commercial, military and recreational vessels in the region and to provide confirmation of known, and identification of unknown navigational hazards. The bathymetry data delivered to the AHO will be used to update Australian Hydrographic Office navigation charts.

The Lord Mayor Shoal to Pitt Shoals survey area is located in the Kimberley Marine Park, extending North-East from previous HIPP surveys along the inshore route through Lacepede Channel towards Cape Leveque and King Sound. The survey area includes Lord Mayor Shoal, North of Pender Bay and Pitt Shoals, North of Cape Leveque. The total survey area is approximately 212 square nautical miles (approximately 393km). The offshore campaign will span for approximately three months – from 10 October 2023 to 2 December 2023.

MMA will be using a third-party vessel (“Outer Limit”) as the primary vessel for 24-hour operations in non-shallow areas, supported by a second, smaller third-party vessel (“Empress”) which will be deployed for 12-hour daylight survey works in shallow water. MMA will also be using a range of subsea equipment throughout the project including multibeam echo sounders, seabed tide gauges, seabed current metres, oceanographic tide buoys and low earth orbit (LEO) Starlink Satellite Communication Technology.

MMA will be employing a team of MMA Surveyors, Data Processors and Survey Engineers. The Empress will carry 8 crew and the Outer Limit will carry 16 crew.

To ensure the protection and conservation of the ecologically and culturally sensitive environment in which the project takes place, MMA has developed strong collaborative relationships with several local community groups, government departments and relevant stakeholders. These stakeholders include Parks Australia, the Bardi and Jawi Niimidiman Aboriginal Corporation, the Department of Biodiversity, Conservations and Attractions (“DBCA”) and the Department of Climate Change, Energy, the Environment and Water (“DCCEEW”). Working in accordance with our Australian Industry Capability and Indigenous Participation Plan, MMA has also provided marine mammal observer training to several Bardi and Jawi Indigenous rangers prior to project mobilisation, with the rangers to be employed offshore by MMA to conduct marine mammal observation scopes onboard the survey vessels.
