Projects
MMA Offshore was contracted by the Australian Government, Department of Defence to undertake the Cape Barren to Babel Island Hydrographic Survey.
MMA Offshore is a primary contractor to oil and gas operators, providing autonomous underwater vehicle solutions to collect seafloor and sub-seafloor data to assist in the engineering design of subsea infrastructure.
MMA Offshore was contracted by the Australian Government, Department of Defence to undertake the Mavis Reef (East), Bonaparte Archipelago Hydrographic Survey. The objective of the Survey was to update Australian Hydrographic Office Charts AUS730, AUS732, AUS320 and AUS323 through the provision of safety of navigation hydrographic surveys.
MMA was contracted by Allseas for the provision of grouting services and grout material on two drilling platforms that are to be decommissioned on the UK Continental Shelf.
MMA designed, fabricated and installed nine buoyant ‘sculptural reef flutes’ individually tethered to the seafloor by reinforced concrete and steel pyramids.
DPIRD awarded MMA an EPCI contract for an artificial reef to be installed 7km off the coast of Hillarys, Western Australia.
