Stabilisation & Scour Protection
MMA’s stabilisation systems are designed to provide the most efficient form of stabilisation for subsea power and umbilical cables in both the offshore wind and oil and gas industries.
We have an extensive range of solutions including rock bolting, articulating concrete mattresses backed by geotextiles, precast concrete clump weights, high-performance armouring of buried pipelines, prefilled grout bags, custom-designed set-in-situ grout bags and grout skirts. Our stabilisation solutions combined with our artificial reef products provide the ideal combination of cable stabilisation and artificial reef habitat enhancement.
Our team of subsea engineers have a significant record of successful scour mitigation projects, with our range of engineered solutions to prevent scour well-tested and proven. Our engineers draw on these case studies to optimise a solution for every application, considering design life, budget, soil type and marine spread capacities.
MMA was contracted to design, supply and install a high performance freespan and stabilisation solution for an HDD pipeline located in the East Gippsland Basin of the Bass Strait.
To accommodate a new 170m long vessel, Citic Pacific required the port’s berthing pocket to be deepened from 10m to 11m.
MMA was awarded the full remedial scope for 23 caissons as part of the bi-annual maintenance program.
MMA's scope was to design and supply a support solution that would protect the J-Tubes from sagging fatigue, complete with a high shoulder to shield J-Tube from high flow velocities.
In June 2015, MMA successfully completed a displacement pile grouting project for Hyundai Heavy Industries Co. Ltd in Malaysia.
As part of their Schiehallion Quad 204 drilling campaign, BP employed a Generation-6 semi-submersible rig for the drilling operations.
