Focus on solutions

Depressurization is a highly complex physical phenomenon. It demands insight into a variety of subjects to correctly analyze and interpret results from calculations, and insight and experience are also necessary to recommend solutions to issues that may be identified.

Petrell has performed numerous project for clients and projects world-wide. Blowdown and flare constitute important elements in the safety strategy, together with e.g. escape and evacuation, active and passive fire protection etc. We find solutions, together with client, that complies with relevant requirements and criteria, always aiming at the best possible solution from safety and economical points of view.

We encourage projects to address depressurisation in the early project phases, when there is time and space to look at alternative designs. See illustration here. Addressing the issue too late does in most cases imply application of passive fire protection. Starting out early, we can play with layout and arrangement, pipe schedules, materials, blowdown valve arrangement and orifice diameter, utilisation of flare capacity etc.

Coaching and support

We provide training, support and guidance. We can follow a project from concept phase to operation.

With our vast experience from design & engineering, we know what it takes.
