Clear scope before work begins. We identify equipment from plot plans, piping and instrumentation diagrams and site inspections, then prepare practical work packs.

  • Equipment and joint identification
  • Gasket and packing specifications
  • Bolt-loading information
  • Labour, inspection and installation requirements
02

Site supervision

Experienced technical support for demanding shutdown and turnaround environments, working alongside your contractors and suppliers.

  • Installation oversight and quality control
  • Contractor and supplier coordination
  • Technical troubleshooting
  • Progress monitoring and reporting
03

Valve repacking programmes

Support for individual problem valves through to programmes involving hundreds of assets, with attention to both installation quality and operating performance.

  • Packing-box inspection and dimensional checks
  • Packing selection, removal and installation
  • Live-loading assessment
  • Leakage review and maintenance recommendations
04

Joint integrity & flange management

A coordinated technical focus across identification, specification, bolt loading, assembly and documentation.

  • Gasket selection and flange inspection
