Current and Recent HOIS Projects

New projects for 2020/21:

  • Optimisation of PEC Technique for CUI by open trials and modelling
  • Corrosion mapping for small bore pipework
  • Development of a remote digital visual inspection recommended practice for unmanned pressure vessel IVI (akin to HOIS-RP-103)
  • HOIS inspection manual - a summary of key points form elected recent HOIS guidance and recommended practice documents.

Further examples of current and previous projects:

  •  Development of guidance:
    •  CUI and external corrosion scabs
    •  Trunnion pipe support inspection
    •  Heat exchanger tubing inspection
    •  Inspection of composite repairs
    •  Inspection of pipe supports
    •  Review and full update of recommended practice for Non-intrusive inspection of pressure vessels, HOIS-RP-103 (formerly a HOIS document but published by DNV GL as DNV GL RP 103)
    •  Guidance notes for HOIS-RP-103
    •  Non intrusive inspection of internally CRA clad vessels
    •  Recommended practice for precision ultrasonic thickness measurements
    •  Guidelines for UAV/UAS based external remote visual inspection (RVI)
    •  Guidance for effective inspection of pipework
    •  Guidance for in-service inspection of caissons
    •  Human factors aspects of NDT in offshore oil & gas
    •  Updates to HOIS RP for in-service digital and film radiography of pipes and input into ISO 20769:2018


  •  Trials and technique evaluation:
    •  Non-intrusive inspection at elevated temperatures
    •  Flange face corrosion
    •  IVI & NII trials on two ex-service pressure vessels
