A hybrid heuristic optimization of maintenance routing and scheduling for offshore wind farms
(Peer reviewed; Journal article, 2019)As the operation and maintenance (O&M) costs constitute a substantial portion of the overall life-cycle cost of offshore wind farms, routing, and scheduling of maintenance are very important for cost reduction. With the ... -
Hybrid Metal Extrusion & Bonding (HYB) - a new technology for solid-state additive manufacturing of aluminium components
(Journal article; Peer reviewed, 2018)This paper demonstrates a concept for a new additive manufacturing process for aluminium alloys, based on the Hybrid Metal Extrusion & Bonding (HYB) technology, along with the potential for further development of the ... -
Hybrid Modelling for Dynamic Reliability Assessments in Subsea Oil and Gas Processing Systems
(Master thesis, 2017)Traditional reliability methods such as fault tree analysis and reliability block diagrams were not designed to account for the complex dynamic behavior of most industrial systems. These traditional reliability methods ... -
A hybrid multi-stage methodology for remaining useful life prediction of control system: Subsea Christmas tree as a case study
(Peer reviewed; Journal article, 2023)With the improvement of control system composition and operation process complexity, the uncertainty in its operation process increases and real-time observation data is difficult to obtain, and the influence of noise also ... -
Hybrid Prognostic Model for Residual Useful Life Estimation of Degraded Equipment
(Master thesis, 2015)As the consequence of the more widely used complex systems, there has been a shift in maintenance strategy. The traditional corrective maintenance is gradually replaced by preventive maintenance or even more advanced ... -
Hybrid Welding of 45 mm High Strength Steel Sections
(Journal article; Peer reviewed, 2017)Thick section welding has significant importance for oil and gas industry in low temperature regions. Arc welding is usually employed providing suitable quality joints with acceptable toughness at low temperatures with ... -
Hydraulic capacity of culverts under sediment transport
(Master thesis, 2014)Sedimentation frequently causes an extensive blockage in culvert which may reduce its design capacity. Culvert guidelines which are extensively used reveal little details about sedimentation in culvert. Requirement of the ... -
Hydraulic capacity of culverts under sediment transport - Multibarrel Setup
(Master thesis, 2014)As a part of the research program Natural hazards Infrastructure for Floods and Landslides (NIFS), the hydraulic performance of the culverts are presently investigated in a scale model study carried out in the NTNU ... -
Hydraulic Fluids for Offshore Applications – the Lubrication Mechanisms of Water-Based Fluids
(Doctoral theses at NTNU;2018:268, Doctoral thesis, 2018)Components used in offshore drilling applications such as hydraulic cylinders wear out earlier than expected due to the combined effect of multidegradation processes like friction, wear, mechanical stresses and corrosion. ... -
Hydraulic Performance of Advanced Treatment Media to Improve Quality of Stormwater from Airports Exposed to De-icing Chemicals
