Neptune Marine Services informed that its Subsea Stabilisation division recently completed the structural grouting of the riser support structure (RSS) under contract to a subsidiary of McDermott for the Inpex-operated Ichthys LNG project in Australia.
McDermott is the appointed main contractor for the subsea umbilicals, risers and flowlines engineering, procurement, construction and installation portion of the LNG project.
Completed offshore in Australian waters in January 2015, the project was the first of this complexity performed by Neptune. A team of seven Neptune personnel, including two engineers, performed 24 hour operations to complete the works safely and on schedule, Neptune said in a statement.
The offshore works commenced following the successful testing of the grout mix design at independent NATA accredited facilities. Subsequent to the project completion, testing was undertaken and the structural grouting passed all compressive strength requirements.
Following completion of the RSS scope of work, Neptune completed the initial campaign of subsea grouting of the scour protection systems (SPS). The SPS were designed, fabricated and installed to the subsea structures prior to installation.
