.... A total length of 790km pipelines and umbilicals has been installed at Snøhvit, in water depths down to 441m. Intervention on these pipelines has been a significant part of the pipeline scope. The organisation of the work is characterised by the remote location and the harsh environment of northern Norway...

... Engineering, The University of Western Australia Perth, Western Australia, Australia ABSTRACT. Subsea well intervention allows increased oil recovery from subsea wells by optimizing production. A method of subsea well intervention that can perform tasks economically and effectively is highly desired...

... Autonomous manipulation refers to the capability of a robot system that performs intervention tasks requiring physical contacts with unstructured environments without continuous human supervision. Today, few Autonomous Underwater Vehicles (AUVs) are equipped with autonomous manipulators. SAUVIM...
