Control Degrees of Freedom for Optimal Operation and Extending Remaining Useful Life
Verheyleweghen, Adriaen (Doctoral theses at NTNU;2020:188, Doctoral thesis, 2020)While the transition to renewable energy sources is happening faster than ever, traditional energy sources such as oil and gas still make up a large part of the energy portfolio, and will continue to do so for many years ... -
Framework for Combined Diagnostics, Prognostics and Optimal Operation of a Subsea Gas Compression System
Verheyleweghen, Adriaen; Jaeschke, Johannes (Journal article, 2017)The efficient and safe operation of subsea gas and oil production systems sets strict requirements to equipment reliability to avoid unplanned breakdowns and costly maintenance interventions. Because of this, condition ... -
Health-Aware Control of a Subsea Compression System
Gjøby, Julie Marie (Master thesis, 2018)Subsea processing technology is enabling production from oil and gas fields with larger water depths, longer tie-back distances and harsher climate conditions. Although moving production and processing facilities to the ... -
Model predictive control of an LNG liquefaction process using Jmodelica.org
Haugberg, Oliver Sale (Master thesis, 2018)In this thesis Model Predictive Control (MPC) theory has been used to develop a controller for a Liquefied Natural Gas (LNG) liquefaction process using the Jmodelica.org framework. Jmodelica.org is an open source platform ... -
Modelling and Simulation of a Two-Stage Refrigeration Cycle
Verheyleweghen, Adriaen (Master thesis, 2015)A two-stage refrigeration cycle was modelled and optimized in MATLAB. The optimum was found to be very flat, resulting in small losses from disturbances and implementation errors. The two unconstrained degrees of freedom ... -
Modelling Failure Mechanisms in Subsea Equipment
Hansen, Siri Kildal (Master thesis, 2016)The oil and gas industry is recently facing a challenge to increase the efficiency and reduce the costs. One way to reduce costs is to better optimize the maintenance strategy. By applying failure mechanism models it could ... -
Optimal operation of a subsea separation system including a coalescence based gravity separator model and a produced water treatment section
Das, Tamal; Heggheim, Sindre Johan; Dudek, Marcin; Verheyleweghen, Adriaen; Jäschke, Johannes (Journal article; Peer reviewed, 2019)In this work, we develop a model for a gravity separator, and we use it together with models from the literature to study the control of a subsea separation system that separates oil, gas, and water from well fluids in ... -
Optimal scheduling of flexible thermal power plants with lifetime enhancement under uncertainty
Rúa, Jairo; Verheyleweghen, Adriaen; Jäschke, Johannes; Nord, Lars O. (Peer reviewed; Journal article, 2021)Renewable energy sources have been the focal point to decarbonise the power sector. The large deployment of these intermittent power generation units requires mechanisms to balance the grid. Thermal power plants can provide ... -
Optimization of Operation and Remaining Lifetime of a Subsea System
Moen, Morten Aulin (Master thesis, 2016)A model of a subsea system was developed and optimization for operation and remaining life time. For the modelling of the remaining life time the compressor efficiency was used as there is no statistical or physical model ... -
Risk-based health-aware control of Åsgard subsea gas compression station
Ims, Julie Berge (Master thesis, 2018)Safe and efficient operation of subsea processing systems imposes strict requirements with respect to equipment design and reliability. This is to avoid accidental shutdowns, which can lead to expensive maintenance ...
