OK TEDI MINING LIMITED FUEL MANAGEMENT SYSTEM
The Ok Tedi mine is an open pit gold and copper mine situated near the headwaters of the Ok Tedi River in Papua New Guinea. The mine is operated by Ok Tedi Mining Limited (OTML), a state-owned company, that holds a large portfolio of exploration leases in the Star Mountains of Western Province, PNG.
SIGNIFICANT DIESEL FUEL USE
The OTML mining operation is energy-intensive and a significant user of diesel fuel in PNG. Diesel is used for all major transportation including:
- Powering of cargo ships and concentrate barges
- Road transportation of materials and goods
- A mining fleet consisting of trucks, shovels and ancillary equipment
- Supplementary power generation.
Due to diesel fuel consumption being a major component of the overall cost of running of the operation, in April 2013 OTML went to market pursuing a fuel management system to manage and reconcile all fuel deliveries and dispensing.
OTML required the FMS to operate over distances of 200 kilometres, in extremely rugged terrain. Temperatures varying from 10 to 50 degrees centigrade, very high humidity and rainfall of 12 metres per year are typical in a setting confronted with challenging communications links. Furthermore, the proposed system had to regulate 24 x 7 user access by way of double security, be simple to operate due to language barriers and even simpler to maintain.
A key OTML requirement was for the system to provide a fuel reconciliation function that reports operation wide fuel usage resulting in a daily snapshot of fuel availability. The report requirement was to provide information on the location and quantity of all fuel, including fuel in transit.
The Romteck Solution
Only Romteck Australia’s Fuel Management System met the list of challenging and demanding requirements in a hostile operational environment.
On engagement, Romteck Australia undertook a comprehensive site survey resulting in a detailed requirements and specification analysis document. Once signed off, the requirement that the system should be simple to install and maintain was addressed. An innovative customised plug and play console was designed and developed that met this necessity. The result was the FMS consoles could be easily fitted or replaced without the need to disturb electrical wiring.
A prototype was developed and the client participated in FAT to ensure compliance with their requirements. To cater for the remote nature of the installations, specialised installation diagnostics equipment was developed that ensured all electrical wiring was correctly installed prior to mounting of the consoles.
Installation and commissioning is currently in progress and the client has been extremely pleased with progress to date.
“Romteck Australia were cooperative from the outset,” said Alan Messenger, Slipstone Senior Lubricants & Fuels Technical Consultant.
“They were adaptive to the challenges presented and demonstrated a willingness to present options and solutions at every opportunity. Since the engagement, Romteck Australia have been responsive, supportive and consistently met and exceeded project targets.”
