Projects
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.
In January 2019, MMA was contracted by Woodside to provide accommodation and walk-to-work vessel services to support platform maintenance operations on Woodside’s Australian assets over two scopes.
The Subsea 7 Emergency Pipeline Repair System Project involved to provide facilities, equipment and personnel support to Subsea 7 as they assembled and tested the EPRS in Tuas, Singapore.
MMA has developed an innovative Subsea Valve System (SVS) that reinstates the full functionality of the XT without having to refurbish or replace the XT and with significant reduced production down time.
The Receipt & Storage of Ichthys Mooring Equipment involved the receipt of three large barge loads of mooring equipment that needed to be offloaded, transported and stored.
