Abstract
This study investigates the development of non-conventional concepts for inspection, maintenance, and repair (IMR) using remotely operated vehicles (ROVs), with particular focus on shore-based control rooms and implications for integrity assessment of subsea facilities. The increased use of such concepts leads to lower carbon footprint, improved working environment, and greater flexibility. Challenges are related to communication quality, the data basis for integrity assessments, access to tools, and the need for robust procedures and training.
It is recommended to ensure that the choice of ROV-IMR concept is suitable for the criticality of the operation, to strengthen training and procedures in line with Human Factors and Man-Technology-Organisastion-principles, and to follow up on communication quality as a critical factor. Further work should focus on experiences from ROV pilots, new technology, and the evaluation of IMR inspection methods.
