Engineering Services

Orana Engineering was engaged by Oaky Creek Coal to assist in design and construction of onsite camp accommodation, including an HV substation for power and potable water supply. Our brief included mechanical, electrical and control systems design, drafting and engineering for the project. Deliverables included scope of works, construction drawings, functional specification, drawing and equipment registers, commissioning and operating spares lists and equipment and instrument data sheets. Orana Engineering provided PLC configuration and commissioning assistance for pump control, acted as Client Representative during construction, managed onsite commissioning of the system, and provided a handover to operations for implementation. Operation & Maintenance Manuals for potable water storage and the HV substation were provided upon completion.

Following commissioning of their Process Water Reverse Osmosis (RO) Plant, Oaky Creek Coal received approximately 150 electrical drawings from the vendor. To provide site personnel with access to the drawings, Oaky Creek engaged Orana Engineering to register these within their existing drawing management system. There are many drawing management systems and tools on the market and Orana Engineering has the capabilities and resources to utilise whatever system is preferred by a client. Oaky Creek Coal sets a very high standard in the industry for the maintenance of drawings and in real terms realises the significant cost benefits that good drawing management delivers in enabling site personnel to perform effectively and safely.

BHP Billiton Cannington Mine, located in North West Queensland is a significant miner and exporter of silver and lead concentrate via the Port of Townsville.   Orana Engineering was engaged by Cannington site maintenance to provide workshop fabrication drawings for a replacement cover to address the issue of corrosion that was present around flanges and access openings on the existing SAG mill trommel sump cover.

To increase productivity and maintain compliance with legislative standards, Glencore Coal employed the services of Orana Engineering to design and manage the electrical aspects of an upgrade to their existing sewage treatment plant. The project was managed on-site by others, with Orana Engineering providing electrical engineering, design, project management and construction / commissioning assistance. Upon completion of installation, Orana Engineering updated all drawings to reflect any changes made, thus providing Glencore Coal with as-built drawings which will make any future maintenance or fault-finding work more efficient and cost effective, as well as providing legislative compliance.

The Coal Handling & Preparation Plant at Oaky Creek Coal utilises a Yokogawa Distributed Control System for control and monitoring of their operation. The system incorporates Yokogawa’s OPC server and Exaquantum data historian. OCC utilises multiple Programmable Logic Controllers for specific operational purposes, with a number of PLCs interfaced back to the DCS for control and monitoring functions. Since 2005, Orana Engineering has provided 24/7 support for Oaky Creek’s control system. Day to day support is provided by remote access, which is cost effective and highly responsive. Additionally, onsite support for hardware solutions and commissioning of larger projects is provided as required.

Melbourne Bio Diesel’s (MBD) James Cook University (JCU) research facility required an elevated level area to allow the installation of a series of tanks for the purpose of storing fresh sea water. Orana Engineering was requested to provide a design solution that not only increased efficiency with the tank draining but to also improve safety around the new tanks.

All mine and industrial sites will list safety as their highest priority within their day to day operations. In line with this philosophy, management at Carpentaria Gold’s Ravenswood Operation enlisted the assistance of Orana Engineering to design a fall arrest system that could be easily removed and repositioned above the multiple leach tanks on site to allow for the safe removal and servicing of tank agitators.

The Glencore Port Operations in Townsville operate an export facility for minerals concentrate and refined copper within the Port of Townsville precinct. The concentrate in-loading rotaside tippler was identified as being at end of life and a feasibility study was commissioned to review a like-for-like replacement option for refurbishment of the tippler. To facilitate feasibility-level costing, Orana Engineering was asked to provide electrical engineering and mechanical engineering assistance with provision of a concept design for the proposed refurbishment and upgrade. By working closely with Glencore, and other consultants engaged on the project, Orana Engineering was able to contribute as part of a collective "owners engineering team" to the feasibility assessment of a significant engineering project in the Townsville Region.

When tasked with a major repair to one of their leaching tanks, operations staff at Carpentaria Gold’s Ravenswood Operations enlisted the assistance of Orana Engineering to develop a solution that would allow for process operations to continue whilst leaching tank TK102 was out of service.

Glencore's Oaky Creek Coal (OCC) operation uses recycled water treated within an onsite RO plant to provide treated water for use by various operations on site. OCC recognised an opportunity to use this clean treated water for water supply to critical equipment such as Horizontal Belt Filters (HBF), improving the quality of water used for equipment, reducing downtime and maintenance requirements associated with poor quality water, in-turn improving the efficiency of the operation of the equipment.
