Valve Integrity Management

Valve Integrity Management

EnerMech has developed a clear and structured approach to Valve Management pulling together all of the lessons learned from both our In House and External Expertise. This allows EnerMech to deliver either a fully integrated service or discrete scope of work that encompass proven best practise.

Our approach to Valve Management allows us to conduct a criticality study as a stand-alone piece of work or as part of a wider approach to all of your valve needs.

As a multi-disciplined mechanical services organisation we pride ourselves in being customer driven, responsive, cost effective and flexible in providing competent and experienced personnel to deliver our customers requirements.

Our primary corporate goal is to ensure EnerMech staff undertake activities in a manner which not only protects their own Health and Safety and the environment, but which also creates a safer workplace for our suppliers and customers.

We will support our customers through the Health and Safety Executive KP4 initiative to assure availability, reliability and management of risk on their asset.

Services include:

  • Commissioning Support
  • Onshore repair and recertification
  • Offshore shutdown and maintenance support
  • Maintenance strategy development
  • Technical Support
  • Valve Stock Management
  • Valve Procurement

Maintenance and Criticality Development

EnerMech has a robust and proven approach to Valve Maintenance.

Our system ensures that Valve Maintenance is carried out in a structured and auditable manner ensuring that the valves are maintained, inspected and certified to meet our clients' operational cost and safety metrics.

Maintenance strategy selection will be made based on detailed analysis using Failure Modes Effects Analysis (FMEA) and Failure Modes Effects Criticality Analysis (FMECA) tools. EnerMech will utilise the failure modes and data from the OREDA database to assign tasks.

Offshore Maintenance and Shutdown Support

EnerMech can deliver breakdown, maintenance and shutdown service packages in support of our customers support operational requirements on a 24/7 basis.

Our Breakdown service delivers a superior response time by giving our customers access to a pool of over eighty field technicians.

"....Customer called EnerMech PSV Manager at 06:45...Technician reported at heliport 08:30...Technician on board Offshore Platform at 13:00.”

Our Maintenance programmes are accurately planned and budgeted and visible to our customers through regular communication ensuring optimised maintenance routines based on criticality studies.

Our Shutdown support draws upon expertise from across our business (valves maintenance, leak testing, flange management,bolting and onsite machining). Our planning procedures confirm work-scopes, identify risk, manage the supply chain and introduce modern technologies and techniques.

EnerMech reduces shutdown costs through, planning, multi-skilled technicians, low cost equipment hire and years of technical expertise in process pipeline services.

  • Break and operating torque testing of emergency shutdown valves
  • Cycle testing of all valve types
  • Pressure testing calibration of safety, vacuum, thermal, pilot operated safety valves
  • Repair/testing of gas hydraulic and pneumatic actuators
  • Valve conversions: to butt weld end, pup extension spools, RTJ — RF thermal jacket manufacture on plug, ball, gate
  • Manufacture, fitting and testing of actuator extension spools for buried service
  • Large capacity machining, including vertical and horizontal turning and boring
  • Ball grinding up to 40" diameter managing component weights over 5 ton
  • Internal and horizontal lapping
  • Weld cladding of stellites, inconnel, CrMo, titanium, low temp materials
  • API trim upgrades including explosive decompression seals
  • Certified specialist pressure welding of pup ends and pressure components
  • Welding of bypass systems, drains, purge points to all valve types
  • Hydraulic bolt tensioning
  • Electric and pneumatic actuator fitting, load testing and closure testing
  • Specialist painting and coating systems internal/external for subsea and offshore requirements

Sealweld sealweldcrop

EnerMech has a strong track record in delivering fit-for-purpose and innovative valve maintenance and integrity solutions.  In support of this service offering we have established a collaboration and distribution agreement in the UK with Sealweld® - a company who, over the last five decades, has developed a range of products and services for routine valve maintenance and emergency valve sealing.  By encompassing the strength and depth of EnerMech and the product knowledge of Sealweld, together we can fundamentally transform valve integrity management.

Through this collaboration agreement, EnerMech is now one of only two companies globally trained and licensed to inject Chameleon Emergency Sealant.  This emergency sealant is a non-hazardous, proprietary blend of semi-synthetic compounds designed specifically for sealing severe valve seat leakage in downstream seating ball & gate valves and can also be used in pipeline situations.  EnerMech has successfully used Chameleon Emergency Sealant on a number of occasions with positive feedback from the client each time.
