Mermaid Marine Dampier Supply Base Expansion

ECM was appointed overall project manager of the $26m expansion which included a 4000t slipway, dredging works involving 750,000 m3 of dredging, design and construction of heavy load out wharf, quarrying, land reclamation and revetment work, installation of potable and fire water storage, pumping and distribution pipe work, storm drainage, pipeline spooling area. An idea of the scope of this work can be found on Mermaid Marine’s website which is at

Karratha Back Beach Boat Ramp (Shire Of Roebourne)

ECM successfully tendered for and constructed the boat ramp and jetty.

This entailed the demolition of the old boat ramp, earthworks, supply and installation of precast concrete panels, jetty fabrication and installation. Work was required to be completed within tidal windows.

Burrup Desalination Plant Supply of Inspection Services (Watercorp)

ECM tendered for the supply of construction project management services to the Watercorp and provided a civil inspector for the duration of the civil work.

Cape Lambert Dust Suppression Pipe work, Rio Tinto (SKM)

Engaged under contract to Rio Tinto with SKM as project managers, ECM was contracted to supply additional dust suppression capability to the iron ore stock piles at Cape Lambert Western Australia. This involved the supply and installation of several kilometers of dust suppression systems including the installation of HDPE and galvanized steel piping, thrust blocks and water cannons. This contract was completed on budget and ahead of program.

East Spar Equipment Building Extension (Apache Energy)

Contracted to Apache Energy, ECM was engaged to extend the existing building as part of an expansion underway on Varanus Island, off the coast of Western Australia. This work included the supply and installation of rock anchors, pre cast concrete footings, structural steel, cladding and other building elements within an operating gas plant. The quarantine and logistical issues required a high degree of planning and coordination.

Cockatoo Island Ship loader and Wharf Engineering Assessment (Cockatoo Iron JV)

ECM was engaged to do a preliminary engineering assessment with the view to ongoing inspection and repair work. ECM was subsequently required to design and install a steel fuel pipeline from the wharf dolphin back to shore.

On-going inspection and maintenance work is pending. Restricted access along the wharf required the design and use of a specific access system and careful design of the pipeline supports and the route.

Cockatoo Island is located at the northern end of the Kimberleys in Western Australia. Access to the island is by barge or light aircraft.

CFW Heavy Lifts

The construction of Phase 5 of the Woodside gas plant on the Burrup Peninsula in Western Australia was achieved using a module approach to assemble the plant. In the course of this work ECM were engaged to take care of the seven modules that needed to be placed onto the LNG wharf. This was different to the rest of the modules were essentially roll on roll off.

The seven modules comprised of 4 loading arms of 75 T each and three process modules at varying weights between 120T and 105 T.

These modules had to be loaded back on a barge using a Manitowoc 2250, the barge transported to the new LNG wharf, connected to a specifically designed mooring system, before being winched alongside(but not contacting), a jack up barge mounted Favco 1500 Crane for loading onto the jetty.

ECM were responsible for

  • Preparation of procedures
  • Lift studies for loading onto the barge
  • Lift studies for loading onto the jetty
  • Installation of Barge mooring gear including procurement
  • Barge deck layout, positioning of the jack up barge, provision of attendant vessels
  • Provision of all labour, supervision and engineering
  • Design and installation of mooring system (ably supported by International Maritime Consultants, Fremantle)
  • Barge, Vessel and Lift supervision

The job went to schedule and without incident.
