Computer vision and thermal monitoring of HMPE fibre rope condition during CBOS testing
Falconer, Shaun; Nordgård-Hansen, Ellen Marie; Grasmo, Geir (Peer reviewed; Journal article, 2020)Fibre rope usage in deep sea lifting operations is gaining more prominence in recent times. With rope minimum break loads (MBL) comparable to that of their steel wire counterparts, the use of high modulus polyethylene ... -
Condition classification of fibre ropes during cyclic bend over sheave testing using machine learning
Falconer, Shaun; Krause, Peter; Bäck, Thomas; Nordgård-Hansen, Ellen Marie; Grasmo, Geir (Peer reviewed; Journal article, 2022)Fibre ropes have been shown to be a viable alternative to steel wire rope for offshore lifting operations. Visual inspection remains a common method of fibre rope condition monitoring and has the potential to be further ... -
Condition monitoring of fibre ropes using machine learning
Falconer, Shaun (Doctoral Dissertations at the University of Agder; no. 368, Doctoral thesis, 2022)The application of fibre ropes in offshore lifting operations has significant potential for further development. With minimum breaking loads (MBL) equivalent to steel wire at similar diameters and almost neutral buoyancy ... -
Gas-Atomized Nickel Silicide Powders Alloyed with Molybdenum, Cobalt, Titanium, Boron, and Vanadium for Additive Manufacturing
Ibrahim, Mohammad; Du, Qiang; Hovig, Even Wilberg; Grasmo, Geir; Hulme, Christopher; Aune, Ragnhild Elizabeth (Peer reviewed; Journal article, 2023)Nickel silicides (NiSi) are renowned for their ability to withstand high temperatures and resist oxidation and corrosion in challenging environments. As a result, these alloys have garnered interest for potential applications ... -
Preparation and Characterization of Spherical Nickel Silicide Powder by Inductively Coupled Plasma Spheroidization for Additive Manufacturing
Tareq, Foysal Kabir; Aune, Ragnhild Elizabeth; Grasmo, Geir; Akhtar, Naureen; Sætre, Tor Oskar (The Minerals, Metals & Materials Series;, Chapter; Peer reviewed, 2022)Metal alloy powder with spherical-shaped morphology, high flowability, and packing density is the main requirements for metal-based additive manufacturing (AM). Among metal alloys, nickel silicide is considered as a potential ... -
Remaining useful life estimation of HMPE rope during CBOS testing through machine learning
Falconer, Shaun; Nordgård-Hansen, Ellen Marie; Grasmo, Geir (Peer reviewed; Journal article, 2021)Fibre rope used in cranes for offshore deployment and recovery has significant potential to perform lifts with smaller cranes and vessels to reach depths limited by weight of steel wire rope. Current condition monitoring ...
