Core Project Outputs

Operations Manuals

Let us take this often labour-intensive task off your hands. Our experience in writing manuals means we know what works and what doesn’t, and we can pull on our library of templates to quickly and effectively deliver operations manuals for any size or scale of process or site, written clearly for the people who use them.

Maintenance Plans

Need help compiling existing maintenance tasks or deciding on what preventative maintenance should be done? We consult with all stakeholders and build schedules that are easy to read and use, while being practical to achieve. We also help write maintenance procedures for any new PM tasks identified.

Process Safety

We know what tools to understand and manage risk for a particular process, design, site, or organisation. We can recommend and facilitate BowTies, HAZOPs, mini-HAZOPs, QRAs, and qualitative assessments so that you can be confident that you have understood the risks and develop a plan to manage these.
