Mechanical Engineering Consultants

Mechanical engineering is the use of energy to create motion while considering environmental influences, material properties and dynamic effects on and between bodies that are in motion.  An in-depth understanding of how things move, behave or interact is required so that these properties can be accommodated within any good mechanical engineering design.

Mechanical engineering requires an understanding of core concepts including mechanics, motion, thermodynamics, materials science, structures and energy.  Using this broad knowledge base, our mechanical engineers are able to analyze the properties and constraints and pull together the different elements required to create solutions and designs that suit operational requirements or resolve problems for our clients.

Orana Engineering has the capabilities and resources to provide mechanical engineering services including:

We provide specialist mechanical engineering services to coal, metalliferous, oil and gas clients as well as industrial and commercial clients. Explore the case studies below for more information on mechanical engineering services by Orana Engineering.

Orana Engineering Mechanical Engineering

UG Conveyor Installations - MG Mechanical Installation

Detailing the installation of mechanical equipment and conveyor structure is one of the final steps for completing a maingate drive-head design. Installations designed by Orana Engineering (MG32, MG33, MG33C, MG34, MG35 & MG36) for Glencore’s Oaky No.1 underground coal mine typically detail the arrangement of drives, transfer stations, take-up units, maintenance equipment and overhead structure to support the carry belt. more


UG Conveyor Installations - MG Civil Installation

The site engineers at Glencore’s Oaky No. 1 underground coal mine have requested the assistance of Orana Engineering to determine the extent of the civil work required to effectively utilise the drive-head equipment in newly mined chambers for conveyor installations for MG32, 33, 33C, 34, 35 & 36. more


CHPP Conveyor Capacity Audit

Vale Carborough Downs Coal Mine (CDCM) required details of the current and possible future capacities of their Module 1 & 2 product conveyors at their coal processing plant in Central Queensland. As a result, Orana Engineering was engaged by the CDCM site engineering and maintenance team to perform the necessary site visits, calculations and reporting. The study consisted of 8 plant conveyors and outlined high level recommendations of modifications required for the plant to achieve higher tonnages. more


Wall Kit Drafting

BHP Billiton Cannington Mine is a significant underground Silver and Lead mining operation located in Western Queensland. Following completion of the ore extraction from each stope, paste backfill is used to fill the open void, which stabilises the area and allows for mining of adjacent stopes. This is achieved by constructing a fill wall across roadways, which provides a stable wall for areas that are being back filled, eliminates intrusion from back filled areas, and allows the back filling to achieve a higher density. more


Tippler Refurbishment Feasibility

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 has been identified as being at end of life and a feasibility study was commissioned in order to review the like-for-like replacement option for refurbishment of the tippler, considering the increased demand on the tippler moving forward. more


Treated Water Boost Pumps

The 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. more

Heavy Vehicle Washdown Facility

MMG’s Karumba Port Facility engaged Orana Engineering to design a heavy vehicle washdown facility to assist with management of concentrate for vehicles and machines used onsite. The project time frame was very short due to operational requirements, whereby Orana Engineering had to work from concept to IFC drawings within 7 days. Orana Engineering’s quality assurance system allowed the design to be completed quickly whilst ensuring a high level of quality for our client. more


UG Conveyor Installations – MG32 Tripper Mechanical Design

In high capacity longwall conveyor arrangements, the installation of a tripper will typical occur after the chamber has been fully developed.

Fire System Audit

BMA Gregory Crinum requested Orana Engineering to perform an audit and inspection of the Crinum underground mine surface fire water system with respect to providing adequate pressure and flow for the Crinum North conveyor system, and in particular the stockpile conveyor. more


Mill Gear Box Frame

The IMT project team at MMG’s Century Zinc operations enlisted the assistance of Orana Engineering to produce a set of fabrication drawings for an existing gear box frame which required replacing. Although the frame itself had been in operation for quite some time, there were no detailed drawings available that could be used for the construction of a replacement unit. more


Flotation Cell Upgrade

In an effort to increase the efficiency of their concentrator, Eloise Copper Mine enlisted the services of Orana Engineering to provide engineering and design assistance for the installation of 3 new copper concentrate scavenger cells, within the existing processing plant. more

MIA Services Audit

Orana Engineering was requested by the BMA Projects Department to assist in completing an audit of air, water and wastewater services at BMA Blackwater Mine in Central Queensland. The work was required in order to determine if the addition of new go-line infrastructure would adversely impact the existing mine industrial area services, and if additional infrastructure or infrastructure upgrades were required. more


Underground Workshop Concept Design

Due to expanding operations, Oaky North underground operations considered that there could be benefit to having an underground workshop including refuelling stations to reduce vehicle travel times and increase efficiencies of vehicle movements. Orana Engineering was engaged to provide concept design and estimating assistance for internal project approvals. more


Crane Lifting Beam

The mother beam of the 40T ship loading crane at the Port of Townsville had been in service for over 30 years and was nearing the end of its service life. With regulatory compliance changes and much improved safety practices in the past 30 years, Xstrata Copper (now Glencore) engaged Orana Engineering to redesign the mother beam based on the existing beam and incorporating required changes to meet the current compliance requirements. This was also an opportunity to improve the current design by incorporating feedback from the crane operators and maintenance personnel. more


UG Conveyor Installations – MG32 Tripper Chamber

Maingate roadways mined to accommodate longwall conveyors at Glencore’s Oaky No. 1 underground coal mine can vary from a few hundred meters to over 4 kilometres in length. Transporting vast quantities of coal over long distances requires a significant amount of power. In some cases the drive-head power is insufficient or is constrained by the allowable belt tension and an additional drive/ power source is required to meet the required operating capacity. Commonly this additional power will come in the form of a driven conveyor tripper installed at a nominal point along the conveyor, which requires the appropriate excavation for the tripper installation inclusive of drives, tripper frame, braking and belt starter. more


Conveyor Upgrade Project

The Carborough Downs Coal underground mine located in Central Queensland, transitioned from a Bord and Pillar mining system to Longwall mining and as a result required to upgrade the capacity of their coal clearance conveyor system. Orana Engineering was engaged to provide Clients Engineering assistance to deliver the final underground conveyor equipment to meet the Longwall production schedule. more
