What We Do
Reliability, integrity &
Reliability, integrity &
maintenance optimisation
When assets underperform, the answer starts with understanding the failure modes, maintenance decisions and operational constraints behind the problem. Optimal combines engineering expertise with practical implementation to help improve reliability, manage integrity risks and make better use of asset data.
Our services cover reliability-centred maintenance (RCM), failure analysis, risk-based inspection, predictive maintenance, spares optimisation and operational readiness. We also support asset management governance and preparation for ISO 55001 certification.
Through ARaaS® — Asset Reliability as a Service, we bring these disciplines together in an ongoing improvement framework, building on your existing maintenance systems and processes.

frequently asked questions
Practical answers on reliability engineering, maintenance improvement and where to start.
What is the difference between asset integrity and reliability?
Asset integrity focuses on an asset’s physical condition and its ability to operate safely within its design limits. Asset reliability focuses on the probability that it will perform its required function for a specified time under stated operating conditions. For example, corrosion in a pump casing is an integrity concern; recurring bearing failures are a reliability concern. The two disciplines work together to support safe, dependable operation. Read our full integrity vs reliability guide.
What is asset performance management?
Asset performance management connects asset strategy, reliability engineering, maintenance activity and performance information to improve lifecycle value. It helps organisations prioritise work according to asset condition, criticality and business risk. Explore our asset performance services.
How can we reduce unplanned equipment downtime?
Start by identifying critical assets, recurring failure modes and weaknesses in the current maintenance programme. Reliability analysis helps prioritise defect elimination, appropriate maintenance tasks and condition monitoring. The right approach depends on the equipment, its operating context and the consequences of failure. Explore maintenance strategy and RCM.
What is reliability-centred maintenance (RCM)?
RCM is a structured approach to deciding how equipment should be maintained. It examines required functions, potential failures and their consequences to identify appropriate maintenance tasks and other actions. Optimal provides RCM studies and maintenance strategy development.
What is ARaaS® — Asset Reliability as a Service?
ARaaS® is Optimal’s ongoing framework for improving asset performance. It connects reliability engineering, maintenance strategy, digital insight and continuous improvement through a cycle of Design, Execute, Monitor, Optimise and Repeat. Discover the ARaaS® framework.
Can Optimal work with our existing CMMS and maintenance data?
The ARaaS® framework builds on existing CMMS information, condition monitoring data and maintenance processes. An initial review establishes what information is available, how it is used and where better data or processes would improve decisions.
Can Optimal help us prepare for ISO 55001 certification?
Optimal provides asset management gap assessment and advisory support to help organisations identify improvement priorities and prepare for ISO 55001 certification. Certification itself is a separate assessment process. Explore ISO 55001 gap assessment.
