FMG4 Iron Ore Terminal Expansion

Client: Total AMS

Location: Port Hedland, Australia

Understanding client rquirements, LDD provided a 'best in class' drilling service for local Western Australian marine contractor Total Australian Mooring Services (Total AMS) as part of the construction of a 200m-long clutched tubular pile wall for FMG's T155 expansion in Port Hedland.

Significantly, this was our first project as LDD Australia, a division of LDD that was established in Perth, Western Australia in May 2011.

We mobilised to site and using our LD408 Reverse Circulation Drilling Rig, and combined with supply of a 914mm drill bit with under-reamering unit to suit, our team worked round the clock to facilitate a Drive-Drill-Drive (3D) process required to install the 1220mm diameter piles.

Through a collaborative approach, we assisted Total AMS in overcoming some significant challenges, such as variable soil and conglomerate layers. By implementing a change in design to incorporate the Drive-Drill-Drive method, LDD made cost and time savings for the client by eliminating the requirement for grout. This change in methodology was instrumental in ensuring piling was completed and met the milestone for planned dredging of the new berthing pocket without incident.

As James Tuckwell, LDD Australia (LDDA) General Manager said, “The benefits of proactively engaging with Total AMS through our local presence have resulted in a unified approach highlighted by the fact that the project milestones were achieved without incident in spite of some significant challenges. This has led to follow on work in the region for LDDA’s RCD drilling equipment and is testament to the efforts of LDD’s experienced site team.”
