Management of valves is one of our core skills and has got us to where we are today as a company. Delivered within or separate to our Asset Management Framework is a focussed Valve Management Framework detailing valve criticality, optimised insurance and operational spares holding as well as detailed inspection, testing, maintenance and diagnostic strategies. Our Valve Management Framework can be broken down into Four categories of valve:
Primarily critical to the safety of your plant, correctly performing actuated isolation valves such as RESDVs, ESVs, SDVs, BDVs and XVs are critical in ensuring safe isolation and system blowdown is available when and as required. Our strategy takes into consideration performance standard requirements that may already exist for some of the valves within this population and develops and expands to ensure all valves within this critical group of valves are managed effectively.
Primarily critical to the operational performance of your plant, correctly performing control and choke valves are vital in optimising your performance efficiency. Ensuring optimal performance is achieved through the analysis and development of a suitable strategy of your installed control and choke valve population.
Often assessed as a subset of the valve population, a PSV is a safety device used to protect equipment from over pressure conditions and so it is imperative that when required to operate, a PSV will open at the predetermined set pressure, flow at the rated capacity at the specified overpressure and then reseat once the system pressure has returned to the normal safe operating level. Due to this, we will build you a specific PSV register with enhanced detail unique to these types of valve using the asset P&IDs to extract a list of all PSVs associated with your operations and then using the test certification history, datasheets and CMMS data we build a profile for each PSV so that we can confirm the exact PSV installed in every location, it’s current operating characteristics and when it is next due for maintenance.
When looking at the total valve population, it is easy to quickly identify some critical valves by their function. These valves are namely PSV’s, Control & Choke Valves and Actuated Valves which form their own specific strategies. However, within the remainder of the population which we will refer to as General Valves, there will be critical valves to your operations which we will identify and establish a suitable strategy for the management of. These will be critical equipment manual isolation valves providing production critical isolations for maintenance of items such as vessels, pumps, compressors, trains, SECE and valves to prevent full plant outages.
