Kimberley Marine Support Base (KMSB) – Broome Floating Wharf

Kimberley Marine Support Base (KMSB) - Broome Floating Wharf

Client: TAMS Group
Location: Port of Broome, WA

Project scope

Broome's ageing wharf was unable to keep pace with the region's extreme tidal range — up to 10 metres within six hours — which restricted port operations to short tidal windows and limited the town's potential as a 24/7 logistics hub for resources, defence, cruise and regional freight. TAMS was engaged by the Kimberley Marine Support Base consortium to design and construct a new floating wharf and approach causeway at the Port of Broome, eliminating the need for dredging and enabling all-tide operations. The completed facility — a floating wharf with an approach trestle causeway and link-span ramp — was completed at the end of 2025 and is a 2026 Australian Construction Achievement Award finalist.

Roam Marine's scope

Headstock installation engineering

Roam Marine designed the temporary access platforms for the headstocks, the installation rigging used to lift and position them, and the trunnions that enabled the headstocks to be safely installed.

Temporary piling & construction support

Scope included design of the temporary piling frame used across the works, crane mats to support crane operations, and "crowsnest" platforms designed specifically for pile cut-off work at height above the water.

Longitudinal beam installation

Roam Marine designed the installation methodology for the longitudinal beams forming the causeway and wharf structure.

Linkspan bridge & restraint jacket lift engineering

Roam Marine carried out the installation rigging design and lift analysis for the linkspan bridge and the restraint jackets, ensuring these major lifts could be executed safely given their scale and the marine environment.

Northern & southern dolphin installation

Roam Marine designed the installation methodology for both the northern and southern dolphins supporting the wharf and berthing structure.

Temporary access systems

Scope also included the temporary gangway design connecting the headstocks, access platforms for the floating barge restraint structure, and a dedicated rigging platform for the restraint jackets — the connective, safety-critical infrastructure that made the rest of the construction sequence possible.


Now operational, the floating wharf enables uninterrupted, all-tide access for resources, defence, bulk cargo, livestock and cruise vessels

Lumsden Point Marine Offloading Facility (MOF)

Lumsden Point Marine Offloading Facility (MOF)

Client: TAMS Group
Location: Port Hedland, WA

Project scope

TAMS was contracted to design and construct a land-backed wharf for FMG at Lumsden Point, Port Hedland. The wharf measures approximately 59m by 22m with a retained height of 16.5m. The main wall is supported by 55 piles at 1625mm diameter, with the anchor wall supported by 19 piles at 1067mm diameter.

Roam Marine's scope

Piling frame design & constructability

Roam Marine designed the piling frames for both the main wall and anchor wall, including all temporary support, access, and lifting arrangements. Our scope also included a constructability review of the client's wharf design.

The main wall piles were driven using a 25m-long, two-level gate frame capable of driving 11 piles at a time — reducing the installation to just 5 frame positions across the full wall. The frame was supported on temporary piles, with pile rollers designed to swing clear so the piling hammer could pass through.

The anchor wall used a simpler single-level gate frame, supported on a barge positioned on the mudflat, driving the anchor piles five at a time from the side of the barge.

Access & construction platforms

Access platforms were installed along both sides of the full length of the pile wall to support welding access, while cube float pontoons were used on the mudflats to provide working access for the anchor wall.

Navigational aids

Roam Marine also designed six permanent gravity-base navigational aids / leads for the MOF, two of which were fitted with lead lights and daymark shapes. The bases were precast concrete with a bolt-on steel central post and upper section.
