A Bayesian approach to risk modeling of autonomous subsea intervention operations
Hegde, Jeevith; Utne, Ingrid Bouwer; Schjølberg, Ingrid; Thorkildsen, Brede (Journal article; Peer reviewed, 2018)The introduction of autonomy in subsea operations may affect operational risk related to Inspection, Maintenance, and Repair (IMR). This article proposes a Bayesian Belief Network (BBN) to model the risk affecting autonomous ... -
Applicability of current remotely operated vehicle standards and guidelines to autonomous subsea IMR operations
Hegde, Jeevith; Utne, Ingrid Bouwer; Schjølberg, Ingrid (Chapter, 2015)This paper employs a combination of literature review and case study methodology to assess the gap between current remotely operated vehicle (ROV) standards and future autonomous IMR operation requirements. With advent of ... -
Application of fuzzy logic for safe autonomous subsea IMR operations
Hegde, Jeevith; Utne, Ingrid Bouwer; Schjølberg, Ingrid; Thorkildsen, Brede (Chapter, 2015)Numerous technical and knowledge gaps pose challenges towards implementation of autonomous subsea intervention, maintenance, and repair operations. One such gap is related to development of methods for ensuring subsea asset ... -
