With an understanding of degradation mechanisms, PATH’s services aim to achieve the design life and improve the durability of assets. The consequences of this can be reduced capital costs, operational costs, environmental impact, risk of failure and downtime whilst increasing safety, service and performance.
Services cover assets made from composites, plastics, coatings and rubbers. Tanks, process vessels and pipes cover 80% of the business. Other assets include ducts and infrastructure. We have extensive training in site health and safety including working at heights, confined space, first aid and fire.
Introduction of Polymer Materials:
Task: From the multitude of materials available, select one for the application.
A material selection study may be broad, such as deciding between the use of composites, rubbers and plastics. Alternatively the material selection may narrow down your choice, such as choosing the plastic material for the application from the many types available such as HDPE, PVDF, PVC, ABS, PP etc. The study may include significant detail, for example, for composite constructions this may include the selection of resin, reinforcement, fillers and lay-up.
Value: With correct material selection an asset lasts its design life with minimal maintenance. This reduces capital expenditure and operating expenditure. The risk of premature failure is reduced resulting in increased safety, increased client & political perceptions, reduced environmental impact, reduced downtime for workers and the asset.
Task: Define the requirements and performance criteria for an asset, a project, a product or a system. Different types of specification can be written depending on whether the purpose is to allow for asset purchase or for design and manufacture.
Value: If you don’t know what you want anything will do!
Task: Prior to constructing assets, document environmental conditions, materials, known deterioration modes and strategies to give reliable assets.
Value: All materials degrade over time. A reliability report is the start of the asset management process. This work gives an understanding of how and when the asset will degrade and what is to be done to reduce the effect of this on the business.
Task: Review designs/specifications/reports etc of 3rd parties.
Documents will be reviewed taking into consideration Australian and international standards, regulations, good industry practice, operating conditions and end use requirements.
Value: Improve engineering, increase reliability of asset.
Task: Verify quality of product at construction/installation. This typically requires inspection and testing for defects and determination of whether the product meets the design documentation. Our technical staff can travel to the site of the client or product manufacturer to provide quality inspection services.
Value: Faults which are picked up at construction and installation can in many cases be fixed immediately leading to longer operating life of the asset. Alternatively replacement may be required and this is more cost effective prior to service. Quality inspection gives the purchaser the security that product is what was ordered.
Polymer Materials Currently Being Used:
Condition Assessment & Monitoring/Corrosion Audit
Task: Determine current condition of asset. Over time monitor the condition of asset.
This typically involves inspection and testing to correlate evidence with design data and known deterioration modes. Inspection may be onsite whilst the plant is online or offline, i.e. PATH provides inspection services for plant shutdowns. PATH also conducts offsite laboratory testing.
Value: Allow planning of refurbishment and replacement of asset.
Task: Following condition assessment services, repair or replacement of the asset may be required. PATH can determine the materials and methods required. PATH can subcontract structural engineering work to registered professional engineers and manage this process.
Value: Provide the information required to get the asset up and running again quickly.
Task: Determine why asset failed.
Value: Learning experience for the client so that failure can be avoided in future. Provide input into remediation method.
Task: Aid client to manage the maintenance and replacement of assets.
Document a system and input the likelihood and consequences of failure of each asset to determine a risk value. Condition assessment, monitoring and remaining life information can be included.
Value: Enhanced management of assets with regards to repair and replacement. Prioritise work so that limited resources are maximised. Money can be saved in areas where the service life can be extended with greater confidence. Reduce failures, complaints and unexpected works by giving warning of assets about to fail. Reducing failures reduces capital costs, operational costs, environmental impact and downtime whilst increasing safety, service and performance.
