ODYSEA, Subsea7 deploy Proxxima technology on Gulf of Mexico pipeline


ODYSEA has announced a landmark achievement in offshore pipeline installation, employing its cutting-edge Goldilocks (GDLX) insulation technology, powered by ExxonMobil’s Proxxima polyolefin thermoset resin systems. This project, involving the installation of approximately eleven kilometers of deepwater pipelines, has been completed successfully with zero safety incidents and ahead of schedule. The utilization of GDLX insulation technology marks a significant advancement in the energy sector, showcasing exceptional performance and efficiency in the Gulf of Mexico.

At the core of this achievement is ODYSEA’s Goldilocks insulation technology, described by CEO Tanmay Desai as “an innovative and game-changing solution.” This technology was applied to flowline and riser pipes for a global supermajor energy client, with Subsea7’s Seven Oceans reel lay vessel executing the offshore installation. Goldilocks insulation represents a leap forward in thermal insulation systems for line pipe, field joints, and subsea structures, offering a faster, safer, and higher quality alternative to traditional methods.

GDLX, a castable thermal insulation coating, leverages a unique molding process that simplifies the traditionally time-intensive, multi-layer application process. This innovation not only enhances portability, enabling on-site insulation worldwide but also significantly reduces waste generation. By accelerating the insulation process, ODYSEA enables clients to achieve operational milestones, such as first oil, sooner than with conventional insulation methods.

The collaboration with ExxonMobil introduces the Proxxima resin system into the GDLX technology, providing a polyolefin thermoset characterized by super-low viscosity and a fast, controllable cure. This resin system boasts a remarkable balance of strength and toughness, resistance to extreme temperature and pressure, no depth limitations, and superior hydrophobic properties that prevent water uptake, thereby preserving insulation integrity.
