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 ... -
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 ... -
Autonomous navigation of an ROV using tightly coupled integration of inertial and pseudo-range measurements
Seel, Katrine (Master thesis, 2017)Underwater navigation is one of the key issues that need to be addressed in order to make operation of underwater vehicles more autonomous. This thesis investigates two different methods for integration of inertial and ... -
ROV Control System for Positioning of Subsea Modules
Henriksen, Eirik Hexeberg (Master thesis, 2014)Installation of deep water Xmas trees for subsea oil production is sometimes done by lowering the tree using one wire. Xmas trees are interfacing with other equip- ment on the seafloor and will therefore need to be positioned, ...
