LEADING dredging and marine construction expert Jan De Nul Group has provided specialised services for port infrastructure works, the offshore oil, gas and renewable energy industries for many years. The group’s civil engineering and environmental activities render its suite of services complete.

In the past eight years Jan De Nul Group has worked on 28 projects in Australia – many of them in Port Hedland. It has executed capital dredging projects in the South West Creek, Stingray Creek and Hunt Point Precinct, pre-cut high spots in the approach channel, and constructed as many as 12 new berth pockets for the inner harbour, including the related maintenance dredging of the harbour basin and access channel. The berth pockets were constructed for different clients, Fortescue Metals Group (five pockets), BHP Billiton Iron Ore (four), Hancock Mining (two) and the Port Hedland Port Authority (one). The creation of 12 berth pockets and their associated departure channels entailed the excavation of a massive 32 million cubic metres of treacherous seabed materials. The soils in Port Hedland are known to be extremely abrasive, so the site was set up was second-to-none to protect the equipment, including a massive metal workshop and clockwork logistics to maintain the dredge vessels.

Across the years Jan De Nul Group has also executed maintenance dredging works in Newcastle; dredging works for the tug boat harbour in Cape Lambert; and was a joint venture partner in the design and construction of Botany Bay container terminal’s 63-hectare extension.

Jan De Nul Group is currently involved with reclamation works for the new parallel runway at Brisbane airport. The project is scheduled to be delivered to the client on schedule.

The group also executes specialised offshore services in Australia. For example, rocks were installed for both the Pluto LNG project and the Reindeer Pipeline crossing to protect them. The group is also completing two projects at Wheatstone: one involves stabilisation work of subsea flow lines and pipelines, and services related to the installation of the gravity based structure; the second involves ballasting works to keep the structure in place.

Jan De Nul Group constantly strives to meet clients’ expectations and was recently endorsed on a performance record sheet: “We would definitely use Jan De Nul on another project”.
