Remote digital visual inspection and robotic inspection of pressure vessels during the GLNG turnaround.

GLNG Turnaround

In 2021 Vertech delivered the inspection services for the Gladstone LNG plant turnaround for Santos. The scope included inspection engineers, advanced NDT, rope access, in-service inspection of pressure equipment and remote digital visual inspection (RDVI) teams.

The turnaround was delivered safely and to a high standard, with exceptional client feedback on the execution.

Pre-Shutdown Work

Review inspection work packs to determine inspection scope requirements in terms of labour and equipment; estimating all equipment and labour hours, providing detailed RDVI, CVI and NDT work packs that included scaffold and lagging requirements as well as organising all equipment and specialist inspection personnel to mobilisation to Site.

Scope of Work

An RDVI crawler lighting the way as it scours the bottom side of a pressure tank as part of a testing procedure.

Vertech successfully completed the based scope of work and several additional inspections that were identified during the shutdown. Our teams of AICIP, NDT, rope access, advanced NDT, tube inspectors and RDVI inspectors completed inspections on time, on budget and with an exceptional safety record:

  • 8 yearly internal and external inspection of hot oil trim cooler and pipeline gas preheater
  • 5 yearly internal and external inspection of 4 lean solvent coolers.
  • 8 yearly internal and external inspection of HP and LP fuel gas ko drum absorber ethylene purger condenser section.
  • 8 yearly internal and external inspection of hot oil surge drum and fuel gas heater lean solvent cooler.
  • 8 yearly internal inspection of ethylene purger absorber section and surge drum.
  • 8 yearly internal and external inspection of propane purger adsorber section, refrigerant accumulator and purger condenser sections.
