Optimization of Maintenance Processes within the Norwegian Railroad Administration: An ERTMS Perspective of the use of CMMS
(Master thesis, 2020)Abstract will be available on 2023-06-10 -
Optimization of maintenances following proof tests for the final element of a safety-instrumented system
(Journal article; Peer reviewed, 2020)Safety-instrumented systems (SISs) have been widely installed to prevent accidental events and mitigate their consequences. Mechanical final elements of SISs often become vulnerable with time due to degradations, but the ... -
Optimization of nozzles and branches welded to pressure vessels or pipes used in chemical processing plants
(Master thesis, 2015)The master project was ready to start in mid-February, so some time was lost in the beginning. The company, Cambi prepared a workstation for me in their office in Asker. The work started with reading about the problem and ... -
Optimization of periodic inspection time of sis subject to a regular proof testing
(Chapter, 2018)Periodic testing is a method to ascertain the availability of Safety Instrumented Systems (SIS). These systems are generally passive and are activated only on demand. Testing is then required to diagnose their current state ... -
Optimization of recertification intervals for PSV based on major accident risk
(Journal article, 2016)Overpressure is a major hazard in the process industry with the potential to lead to a major accident. Pressure Safety Valves (PSVs) are often used as the last layer of protection against such a hazard and require regular ... -
Optimization of Sample Size for Two-Point Diameter Verification in Coordinate Measurements
(LNEE;volume 484, Journal article; Peer reviewed, 2019)This paper investigates the possibility for reduction of sample size for inspection of two-point diameters with a coordinate measuring machine, by use of statistical methods. The statistical methods implement the parametric ... -
Optimize Operations and Future Development on Multi-Purpose Tana Beles Hydropower Project
(Master thesis, 2016)Abstract Different projects in Tana-Beles basins were identified as water resource development project and implemented to attain the country s development goals. One of these projects is Tana-Beles multipurpose hydropower ... -
Optimize Resistance to buckling under external hydrostatic Pressure of thin walled Composite Tubes
(Master thesis, 2014)Composite tubes are a very good alternative to steel tubes in applications requiring low weight and high stiffness. For composite tubes to replace traditional steel tubes in demanding environments, such as in the subsea ... -
Optimizing condition monitoring for dynamic health and risk management
(Doctoral theses at NTNU;2021:74, Doctoral thesis, 2021)This Ph.D. thesis explains the concepts of condition monitoring and associated challenges in maintenance modeling for subsea facilities. Thesis’s main objective is to develop systematic frameworks to assess the performance ... -
Optimizing Leather Cutting Process in Make-to-Order Production to Increase Hide Utilization
(Chapter, 2018)The growing trend of customization in the leather furniture industry has increased the need for many companies to switch from Make-To-Stock (MTS) to Make-To-Order (MTO) strategy. The shift to high-mix and low-volume presents ... -
Optimizing operations and network communications for oceanographic monitoring systems
(Master thesis, 2020)This thesis is concerned about oceanographic monitoring systems and the optimization of their operations, especially their network communications. Three research questions have been discussed, focusing them on the ... -
