operations and maintenance

As an operations and maintenance (O&M) provider we work in partnership with our clients.

We don’t just provide a service, we operate facilities as if they’re our own.

We share the common goal of improving performance and return on investment throughout the asset’s operational lifecycle.

px provides operations and maintenance services on some of the UK’s most strategic infrastructure. We work on facilities across a diverse range of high hazard industries including power, gas, fuel storage, waste, biofuel, renewable energy and petrochemicals.

Our services range from commissioning to routine operations and long term asset management, as well as being permit holder for safety and environmental legislation.

With an established presence, world class systems, highly trained staff, and strong relationships with regulatory bodies, we offer our clients O&M services that are reliable, secure and cost effective asset management solutions, maximising return and minimising risk.

We believe there are four critical success factors for O&M

  • Relationships – working in partnership with our clients is the only way an asset can perform at optimal levels.
  • Safety, health and environmental performance – we operate a number of Top Tier COMAH sites and the systems and processes used at these sites are used across our business.
  • Employees – we pride ourselves on our expert team, which includes some of the most experienced, highly trained and motivated people in the sector.
  • Proven track record –  25 years experience of operating and maintaining strategic industrial assets, and recognised and awarded by our industry bodies.
operational services

We ensure that operational and commercial activities are aligned to maximise profitability without compromising safety.
Our teams operate the plant and provide routine, planned and breakdown maintenance on the facilities.
In addition, the teams are involved in either a supervisory or monitoring role with all major maintenance on the facility equipment.

mobilisation and transition

We have extensive experience of transitioning existing operational teams into our business and recruiting and mobilising new teams.

Our key objectives during a transition are to:

  • maintain high levels of Safety, Health and Environmental (SHE) performance;
  • maintain high levels of reliability and availability;
  • progress the transfer of corporate systems, information and competence;
  • establish a full O&M structure providing a sense of stability for site personnel;
  • if applicable establish a thorough understanding of the facility and its history;
  • review operating procedures, method statements and risk assessments; and
  • where appropriate, evaluate maintenance sub-contracts and spares arrangements.


operational excellence

We are committed to delivering maximum return on investment for our clients while minimising risk. Each operational site is benchmarked against our operating model (based upon IOGP report 510) which covers key areas such as:

  • Process safety management and Management of Change (MOC)
  • Occupational SHE management
  • Behavioural safety management
  • Implementation of integrated management systems
  • Disciplined operations and maintenance
  • Continuous Improvement

health, safety & environment

We believe that harm to people, environment, asset and reputation, as a direct result of our activities, can and must be prevented.  Our ZERO Harm Charter outlines our commitment to world class standards of safety, health and environmental control and avoiding all cases of workplace ill health, injuries and incidents, including damage to the environment.

This is achieved by the creation of working conditions that encourage positive attitudes, behaviours and contributions from all personnel.

maintenance & plant development

We see our role, as plant operator, as determining the appropriate level of maintenance required to deliver plant reliability while maintain statutory compliance, controlling risks and minimising costs for our clients.
We have significant expertise in the optimisation of assets, providing our clients with high quality technical assistance across engineering disciplines.

maintenance and outages

We believe that a maintenance programme has to exceed the basic requirement of keeping the plant operating and we work with our clients to find a program which meets each plants short and long term objectives. The essence of the programmes we deliver is one of quality management – where the staff are in control of the plant equipment and not the other way around.

It is widely recognised that statutory inspections are the largest source of plant downtime. Managing this process is part of our O&M operations, and due to our best practice procedures we are able to reduce the duration and frequency of inspections with no impact on the quality of work undertaken.

They’ve led numerous optimisation projects at plants and facilities operated by px, as well as for independent clients. These include performance enhancing studies and modifications, life extension projects and reporting systems.
