AMOG's Longitudinally Grooved Suppression (LGS®) modules are set to be deployed off the coast of Australia, as part of Phase 1 of a multi-million dollar contract. Designed to reduce drag and suppress vortex-induced vibration on subsea infrastructure, this will be the first time they are applied to a shallow-depth field.

The project will include the in-situ installation of the LGS® modules, which are manufactured under licence by Matrix Composites and Engineering Pty Ltd, onto an existing installed pipeline off the coast of Australia. With huge capital costs associated with exploration and new installations, and the high operating costs of deepwater rigs, shallow water depths are starting to receive a greater amount of attention, according to Matrix' CEO Aaron Begley*.

LGS technology is a patented geometry that, when applied to drilling riser buoyancy modules, can be used to reduce drag and riser fatigue, as well as improve stability.

This is the third order for LGS® modules, the second installation having recently been deployed in a strong current region in the Gulf of Mexico. AMOG is looking forward to analysing these test results later this year, to provide greater insight into how this technology can benefit operators.
