On commission from the PSA, Ramboll has conducted a study on the evaluation of damage detection and the structural health monitoring (SHM) of offshore structures in the petroleum industry.
Technology and damage detection
In recent years, digitalisation has provided opportunities for the improved health monitoring of structures. Such digitalisation comprises wireless sensors, data acquisition and data processing, digital twins and machine-learning algorithms for damage detection. In principle, SHM aims at addressing parameters that indicate the state of the structure under investigation. For these SHM methods to be of use, it is important to assess whether the typical and significant damage to offshore structures that occurs can be detected by such methods.
Basis of the report
In 2022, Ramboll conducted a study for the Petroleum Safety Authority Norway to survey damage to structures reported to the PSA (and previously to the Norwegian Petroleum Directorate) from 1974 to 2021, and to assess the extent to which SHM methods and digital solutions could contribute to damage detection. The work also included a review of SHM standards from other industries.
The study builds on a number of previous projects in adjacent areas, both from the Petroleum Safety Authority Norway and other countries’ oil and gas authorities.
