ENGINEERED PRESERVATION
PSM Upstream solutions
Methodology
Service Offering
PSM specialises in preservation of critical spares in the energy sector. Preservation is a core business within PSM, with extensive in-house research and development carried out to ensure fit for purpose solutions are implemented. With years of experience, we are confident that we can successfully preserve any type of asset, from any industry and in any condition.
Asset Preservation
From sensitive labyrinth seals, bearings of all types, electric motors, pumps, valves, to complex turbo machinery, oversized transformers and subsea equipment. We have the skillsets, method statements and systems in place to successfully inspect and preserve all assets and provide the Client with advice and details of its condition in reports and photos.
Proactive Protection
We prioritise preventive and proactive preservation of materials and are experts in corrosion protection through humidity control and application of temporary protectants.
Other preventive preservation is achieved by rotation of shafts, exercising seats and seals of valves, electrical diagnostics of motors and Electric Flying Leads and dust and humidity control of all types of assets. In all cases a combination of the use of temporary protections, oils, greases, vapour phase corrosion inhibitors (VpCI), vapour barrier and desiccants are utilised. All products are chosen with the environment and material compatibility in mind.
Our in-house designed and fabricated packaging creates a dust free and humidity controllable environment that ensures preservation and protection of the asset is maintained. They also double over as transportation compliant vessels suitable for any environment.
All our methods align with industry best practices, Australian standards and client requirements.
Method Statements
Our Inventory Management / Maintenance Management system Asset Panda drives the workflow together with specialised method statements creating a work order in the form of a service ticket for the Technicians.
Our method statements are designed to be a stand alone set of instructions, easy to implement by our Technicians. This is achieved by nominating all tooling, equipment and consumables required as well as a set of instructions and acceptance criteria for each step of the service.
Common to all our method statements are the following tasks:
General and close visual inspections
Retrieving all paperwork and recording/photographing part number and serial numbers
Cleaning all remnants of spent temporary protectant and any dust/ dirt
Clean and scotchbrite any surface corrosion as required
Photograph asset at every step of the method statement
Record and photograph any anomalies and quarantine as required
Perform asset preservation as per the specific method statement
Compile a detailed report at the end of the asset service, complete with photos
An excerpt from the method statement of commonly preserved assets is shown below:
Electric Motors
- Remove junction box covers and perform inspection
- Perform motor electrical diagnostics testing
- Rotate motor shaft
- Fabricate shaft lock if non present
Bearings, bushings and couplings
- Apply TP 6 / TP 9 to surfaces by spraying or fogging
- Place any loose items in VpCI EcoCorr sleeve
- Wrap unprotected threaded or sealing surfaces in denso tape
Valves
- Remove any flange protection and inspect valve internals, seats and seals.
- Grease actuator / gear box
- Slowly actuate valve open and close anomalies
Gears and shafts
- Release / vent any trapped pressure
- Remove clamp collars and note break out torques
- Rotate gear / shaft
Hydraulic Flying Leads (HFL)
- Remove protective covers on termination heads and coupler protective covers and inspect
- Connect HPU to hydraulic fluid supply, flush and take readings until required fluid cleanliness is achieved
- Perform pressure / leak test
- With T&F plates removed and with coupler protective covers installed on termination heads, pressure wash exterior of entire HFL
Valves
- Remove protective covers on connectors and inspect connectors and cabling
- Remove calcareous deposits using acid
- Verify wiring diagram
- Perform cleaning of connector faces
- Connect test connectors and perform continuity test and measure insulation resistance
- Perform preservation services
Sustainability
The sustainability and efficiency of products that we use are critical to us.
Desiccants
Our desiccant dosage adheres to the AS 2400.18 standard (Part 18 – use of desiccants in packaging) and we have successfully implemented a system where the desiccants can be re-activated and re-used. Being clay based and not silica derived, the desiccants can be disposed of as general waste instead of controlled waste.
Cardboard Boxes
Assets packaged in our cardboard boxes are padded with protective webbing made from repurposed cardboard. This solution provides the assets with outstanding protection while reducing packaging waste as its made out of cardboard that was earmarked for disposal.
Re-usable Crates
PSM crates are built with re-use in mind. They have been designed so they can be opened and the material within can be inspected without damage to the crate. Solutions such as hex screws instead of nails, humidity cards and desiccants which are easy to access and replace all minimise the wear and tear on the crate.
Biodegradable Materials
As part of our sustainable preservation methods, we are the only supplier in Australia that can offer biodegradable Cortec Eco-Corr wrapping sleeve. This product meets the EN 13432/ASTM D6400 – standard for commercial composting.
