Capabilities & Projects


Thanks to decades of experience in thousands of projects around the world, HDI Lucas, a subsidiary of Spiecapag Australia and sister company of HDI France, is a key player in the field of horizontal directional drilling.

Our reputation is built on our continuously evolving engineering and our ability to adapt to any kind of project. The skills of our teams and the reliability of our equipment allow us to redefine the limits for pipeline installation beneath natural or artificial obstacles whilst respecting the environment.

HDI Lucas’ drilling rigs offer a pulling capacity ranging between 35 and 400 tons. They allow for the installation of small size pipelines over short distances as well as large diameter pipelines (up to DN 1400) over very long distances.

Rigs are trailer or crawler mounted and consist of a central beam rack with a carriage moved by pinions powered by hydraulic motors. Hydraulic rotary motors located on the carriage provide the necessary rotary force.

Each drilling rig has its own control cabin, steering kit, high pressure pump and other ancillary equipment forming a complete and autonomous drilling spread. The HD 650 and HD 350 models are designed and manufactured in-house.

Client: APA
Location: Darwin (NT), Australia
Completion: 2021
Pipe Diameter: 12” (DN300)

Territory Generation operates the Channel Island Power Station, which is the largest power station in the Northern Territory and the main source of electricity for the Darwin-Katherine interconnected system.

The section of Amadeus Gas Pipeline that crosses the Channel Island Bridge near the power station reduced in nominal diameter from DN300 to DN200. This existing DN200 pipeline under the bridge needed to be replaced by installing a replacement DN300 pipeline under the waterway.

A new 1350m long HDD crossing was completed through varying geology up to 250mpa rock strength. The profile was very complex with a compound curve arrangement completed to minimum pipe bending radius during the last 400m of the crossing.


Client: Newcrest
Location: Lihir Is, New Ireland, Papua New Guinea
Completion: 2021/2023
Pipe Diameter: 48” (DN1200)

The first Lihir Island Tailings Pipeline Rehabilitation Project TK050 involved the recovery and reinstallation of a DN1200 HDPE liner pipe used for the placement of tailings to water depth of more than 100m. The project was located on Lihir Island at a gold mine with dense infrastructure, 643km off the coast of mainland Papua New Guinea. At over 200m in length the tailings pipe was connected to a submerged tank that gravity fed to the ocean at an angle of 37 degrees.

The second, TK2050, involved the relining of another existing DN1200 pipe (approximatively 300m. in length) laid at 33 degrees.


Client: JTC Corporation
Country: Singapore

Pipe Diameter: 10″ (DN250)

A significant reclamation project being completed by JTC Corporation at the Tuas Western Coast in Singapore. It was necessary for SingTel’s undersea cable systems, to be diverted to allow the dredging works to proceed.

Two 700m shore approaches (250mm OD Casing) were installed 45m deep beyond the proposed dredging zone.

Project works included all required support activities; construction and maintenance of launch pit and work area; provision and transportation of consumables, material and equipment.


Client: Fletcher (Watercare)
Country: Rosedale, Auckland, North Island, New Zealand
Completion: 2020
Pipe Diameter: up to 20” (DN500)

The Northern Interceptor Pipeline Project is new wastewater pipe designed to redirect flows from the North-western areas of Auckland (New Zealand) to the Rosedale Wastewater Treatment Plant in Albany.

The final pipeline design incorporates dual DN500 HDPE PN16 sewage rising mains and a DN200 HDPE conduit for future fibre optic cable installations under the Upper Waitematā Harbour and Te Wharau Creek.

The total drilling length was more than 5,000m with each of the triple harbour crossings each exceeding more than 1,100m in length and through parallel curves. The triple Te Wharau Creek crossings each exceed 560m in length.
The crossings were completed in challenging rock and clay conditions, requiring detailed planning and preparation to ensure the crossings were constructible and risk was as low as possible. The bottom hole assemblies were manufactured utilising variable jet configurations to overcome the East Coast Bays Waitematā rock and sticky clay. The project also needed to complete detailed planning and negotiation to secure suitable stringing areas, as the urban location of the pipeline meant that options large enough to be safe and suitable were severely limited.

The world’s longest landfall at the time

Client: Shell Todd New Zealand
Location: New Plymouth, North Island, New Zealand
Completion: 2007
Pipe Diameter: up to 24” (DN600)

The project’s HDD landfall traverses a 33-metre cliff and an offshore reef. At 1,850m overall, at the time this was the world’s longest landfall.

One of the key challenges was traversing the many different geological layers along the HDD alignment. In order to drill through the surface layers of pyroclastic boulders and cobbles, a casing was hammered approximately 146 m using a 2,000-ton pneumatic hammer. We used an American Augers DD1100 rig. It has 500 tonnes of push/pull capacity and 136 kNm of torque. It is the largest rig in the Asia Pacific, and among the five largest in the world. We used a centrifuge to control the superfine cuttings from the siltstone and mud.

Project works included all required support activities, construction and maintenance of launch pit and work area, provision and transportation of consumables, material and equipment.
