Water Cannon Repair
Date: January 2021
Project: Water Cannon Repair
Integrated Reliability Solutions have been involved with reliability for over 15 years and considered by many as an industry leader in this field.
Ageing Water Cannon
Integrated Reliability Solutions were approached by one of the Hunter Valley coal mines to inspect and come up with a suitable repair for the leaking water cannons. On inspection of the water cannon, it was noted that a number of components had worn due to lack of lubrication which allowed the water to leak when not in use.
Failure points
- “O” Rings
- Upper Bearing (coupling).
- Lower Bearing (Coupling).
- Nozzle.
- Isolation valve
Strip, Inspect, Quote & Repair
- The water cannon is stripped & photos taken.
- An inspection report is provided to the customer together with a quotation to repair.
- Once approval is provided & a purchase order is received IRS will start the repair.
- Coupling faces are repaired or replaced depending on the severity of wear/ corrosion.
- New bearing & seal repair kits are procured & installed.
- Grease is applied and water cannon assembled.
- Grease points are filled.
- A pressure test is completed to ensure that no leaks are detected prior to dispatch.
- The water cannon is painted & packed ready for dispatch.
- Transport is then arranged for water cannon to be returned to site.

During the repair of the water cannon, IRS modify the bearings to allow grease to reach the sealing “O” ring. This helps prevent corrosion and “O” ring tear.
IRS also recommend fitting a single point lubricator to the swivel points to ensure sufficient grease is present at all times. We have found that this addition extends the life cannon.
Assembled tested and painted. Ready for despatch
Case Studies
10,000 kg Grease Tank Solution
In early 2022 IRS was commissioned by a client to design and build a custom 10,000kg Grease Tank Solution. Features included: Overfill protection, Heater - Thermostat controlled, Sim Card for data transfer, Internal pressure relief and much more.
Underground 30,000 Litre Fuel Tank Module
Integrated Reliability Solutions was commissioned to design and build a 30,000 litre underground refuelling solution for a client in May 2022.

Breather and Sampling Point Audit - Nth Queensland
Glencore site Collinsville CHPP had requested that we undertake an audit on their current Breather and Sampling Points, to identify opportunities to improve the cleanliness of the air entering the compartments, oil and the accuracy and process of taking oil samples.
MagnaDrive saves Plant Feed Conveyor
On the 4th of November 2007, the plant feed conveyor failed to start after the operator attempted to restart operations following a plant stoppage.

MagnaDrive Coupling Air Preheater
Minnesota Power was experiencing vibration problems on their Air Pre-Heaters. In an effort to correct this problem, Minnesota Power implemented a preventative maintenance procedure that required all couplings to be re-greased during every outage.
Hose Down Pump
The Magnadrive Adjustable Speed Drive Coupling (ASD) was installed on the Hose Down Pump at South Walker Creek CHPP on the 4th October 2007.
Bearing Skidding
Over the last three years IRS has been monitoring motor bearings displaying various stages of fatigue.
Electric Motor Bearing Defects
The site was experiencing a high frequency of electric motor bearing faults. Condition monitoring reports had identified specific motors as manifesting bearing defects and had suggested that a “lack of lubricant” was a significant factor contributing to the defects.
Grease Contamination
Over the course of several months, site maintenance personnel observed that lubrication system components were failing at a rate higher then what would normally be expected.
