Subsea Construction & Maintenance

MMA offers a complementary range of subsea services to support construction, inspection, repair and maintenance, and decommissioning projects to clients in the oil and gas, renewable, shipping, defence, and marine infrastructure industries.

We own and operate a fleet of both work class and inspection class ROV systems and have partnerships with subcontracted ROV providers to offer unique and economic solutions with uncompromised performance and dependability.

Our in-house diving equipment is state-of-art, and with strategic allocation of resources and highly experienced personnel, our commercial diving team has the capability to complete projects of any scale to the highest industry standards.

We have an in-house capability to design, manufacture, supply, and install a range of pipeline stabilisation and protection systems, with our product range having been developed over years of research, product design, and offshore application. We also retain offshore grouting equipment providing structural grouting services and freespan correction services.
