Cyclone Mooring Pile Grouting

Subcon was contracted by TAMS to perform the grouting operations for the installation of thirty-two cyclone mooring pies at Mangrove Passage, Onslow. These works were completed in three phases to accommodate the pile installation schedule and cyclone season.


  • The SGM1000 is safer and quieter to operate and faster to mobilise
  • Dust extractors prevented exposure of cement dust to people, equipment and the environment
  • Specially designed grout mix was provided to supply a high strength product

The project utilised Subcon’s compact SGM1000 Jet Mixers. These unique skids include an integrated recirculating jet mixer, agitator tank and a monopump. Our “single skid” philosophy minimises handling, freight, seafastening, hoses on deck and electrical wiring.

The SGM1000 is safer and quieter to operate and faster to mobilise. Dust extractor on the hood of the mixer ensured that the personnel, vessel and environment were not exposed to cement dust.

A purpose grout mix designed was developed and tested in conjunction with a leading additives supplier to provide a high early strength, low shrinkage grout with high sulphate resistivity and a 28 day strength

Subcon’s preparation, safety culture, our employees’ onsite work ethic and reliable equipment meant that each phase of the project was completed ahead of schedule.
