Examples of Industrial Work Performed by RBD Contracting Services

HYDRO TASMANIA:

RBD Contracting has been performing work for Hydro Tasmania across the state for the last 8 years.

We started by installing equipment to interface to the existing machine control as part of the Bass-link System Protection Scheme.

Recent installations performed by RBD Contracting are;

Complete electrical installation for an entire power station alternator and turbine at Tungatinah, including the decommissioning, electrical strip out of the old controls and cabling, then the complete electrical and instrumentation automation of each section of the machine with several hundred PLC I\O points and touch screen control, pressure, temperature and flow instrumentation installation, high voltage connections, earthing, fibre and communication installation, exitation transformer installation and assist with pre-commissioning and commissioning.

The mechanical and electrical installation of several Areva High Voltage Circuit Breakers at Catagunya and Poatina including HV cable terminations, busbar work and control wiring.

The installation of the Main Inlet Valve and Pulsation Protection Projects at Liapootah Power Station including the installation of cable tray, cables, cabinets PLC’s, field devices, control wiring and commissioning.

Reticulated power supply for the contractor’s site and equipment for the Catagunya Dam Strengthening Project.

Installation of the Lake Margaret Lower Power Station earth mat on the West Coast.

The electrical protection installation for the 7 generating machines at the heritage listed Lake Margaret Power Station on the West Coast.

The upgrade of Electrical Protection for the Mackintosh & Bastyan Power Stations including the Mackintosh Transmission Line Protection.

The installation of Electrical Protection of the SCADA and Synchroniser Upgrade Projects at John Butters, Tribute, Liapootah, Reece, Gordon and Catagunya Power Stations.

The installation of the Main Inlet Valve and Pulsation Protection Projects at John Butters, Tribute, Liapootah and Catagunya Power Stations. These projects required 2 – 18 week outages at each station for the work to be carried out.

This involved removing old equipment and wiring from the Machine Panels and installing new equipment and instrumentation, then installing, connecting and commissioning the cabling to interface to the existing system.

Australain Paper Wesley Vale Mill

Prior to the closure of Australian Paper’s Wesley Vale Paper Mill in 2010, RBD Contracting had been onsite at the Australian Paper Wesley Vale Mill since our company was formed. In that time we have performed a range of functions at the site.

These include:

  • Project management for electrical installations plus other civil work projects.

  • Electrical designs for capital projects.

  • Capital expenditure electrical installations.

Installations performed by RBD Contracting at the Wesley Vale site are:
