Optimization models for the plugging and abandoning of offshore oil and gas fields
(Doctoral theses at NTNU;2020:324, Doctoral thesis, 2020)This thesis applies operations research methods to planning problems related to the plugging and abandoning of offshore oil and gas wells. We consider two problem settings, for which we develop new models and solution ... -
Optimization of a Ship-Based Logistics System for Carbon Capture and Storage
(Peer reviewed; Journal article, 2022)Carbon Capture and Storage (CCS) is the process of capturing CO2 before it enters the atmosphere, transporting it, and then storing the CO2 in a permanent underground storage site. CCS is projected to play an important ... -
Optimization of a Supply Vessel Scheduling and Fuel Type Allocation Problem for a Hellenic Oil Company
(Master thesis, 2013)This master thesis is concerned with solving a combined fuel supply vessel scheduling and fuel type allocation problem. The problem is provided by a Hellenic oil company. The company has a small, fixed fleet of fuel supply ... -
Optimization of combined ship routing and inventory management in the salmon farming industry
(Master thesis, 2014)Fish feed is the largest component of a salmon farmer s production costs and lostfeed days are a large cost driver. Norway s largest salmon farmer, Marine HarvestNorway, hopes to cut costs and increase reliability of feed ... -
Optimization of complex simulation models with stochastic gradient methods
(Chapter, 2018)We describe the structure of stochastic optimization solver SQG (Stochastic QuasiGradient), which implements stochastic gradient methods for optimization of complex stochastic simulation models. The solver finds the ... -
