1.1 About Evaco Valve Integrity Management System .
EVACO Valve Integrity Management System refers to the integrity of Valve system elements, these
elements consist of careful handling and storing of valves prior to installation, as well as following correct procedure during pre-commissioning, commissioning, operating, and maintaining the valve.
The integrity of all these elements ensures more efficient and safe operation with a reduced chance of
production loss and/or isolation failure.
All the above elements are recorded, reported, and analyzed through a computerized database system.
Valve Integrity Management System (VIMS) Services are:
Pre-Commissioning/Commissioning Services.
Scheduled Maintenance Service.
Emergency, Shutdown Services.
Machining / Refurbishment Services.
Personal advisor and in-house training service.
Pre-Commissioning/Commissioning Services .
This service is the most crucial step taken toward ensuring that a pipeline system runs
Efficiently and safely, and it will be applied as following:
Pre-Commissioning Services:
- Create proper procedures for valve handling, transportation and storage to prevent
contamination and damage of the valve assembly. - Review/Correct the valve selection parameter based on application required.
- Visual Inspection to ensure that all valve components as design drawing (injection fitting,
body vent/drain, gearbox ….etc.). - Replace the factory grease with high-quality synthetic lubricant, unless it was ordered
initially filled with synthetic grease. - Function and hydrostatic test the installed valves.
Commissioning Services:
- Identify and determine the valve location and specification according to PFD.
- Inspect the valves after installation to ensure a proper Installation and detect any missing
parts. - Top up the valve cavity with synthetic grease.
- Function and pressure test the installed valves.
- Tag each valve with the EVACO tag number, which will be used in tracking the valve, and create history records for pipeline valve systems.
Performing the previous few steps, ensure that the valve is properly installed and
Voided any undesired defects/malfunction during the initial operation.
Scheduled Maintenance Service
Thousands of valves in every sector of oil and gas industry are scheduled for replacement every year causing loss of production due to the lack of maintenance, by applying EVACO scheduled maintenance service, the valve reliability and integrity will be improved, reducing operational risk and down time .
Scheduled maintenance divided in two categories:
Preventive Maintenance (PM) .
• Visual Inspection.
• Cavity flushing
• Function test.
• Lubrication.
• Valve Packing Replacement “If Required”
• Pressure test.
Corrective Maintenance (CM) .
• Repair malfunction valves on site as possible.
• The un-repairable valves repaired off site, which can be performed in EVACO Client workshop.
As per the valves manufacturer recommendations, the valve PM schedule should be on semi-annual basis,
it may seem excessive, but a small investment in time and PM could potentially protect your investments.
Emergency and Shutdown Services
Emergency Services.
This service is subjected to solve the unexpected/ suddenly valves problems, likewise it can solve operation
problems, decrease the loss time and reduce/eliminate unplanned shutdown. This service covers the
following:
Preparing the bolts for fast and easy removal.
Prepare the spare parts and valves which will be used in shutdown.
Evaluate and control Emission / leakage.
Valve sealant (amount and type of sealant depend on leakage rate, application and valve size).
Repair the reported malfunction valve.
Replace the damaged parts/ valves on line.
Provide recommendations that reduce/prevent the occurrence of problems.
In case of temporally solutions, we will submit full procedures to solve the problems permanently.
In emergency cases, our services will void most of forced shutdowns .
Well Organized management of planned shutdown, will lead to reduction of shutdown time and production loss .
