Joint Acoustic and Electrical Measurements for Unfrozen Water Saturation Estimate—A Review
(Chapter, 2019)The previous laboratory study of joint electrical resistivity and acoustic velocity measurements is reviewed for both consolidated and unconsolidated permafrost in this paper. The relation of logarithm of resistivity log(R) ... -
Joint AVA analysis -Reflectivity below a strong reflector
(Master thesis, 2010)The reflectivity below a strong reector is a known problem. By looking at a real case and using real input values an evaluation of the modeling of such a case is done in this thesis. An introduction presenting all the ... -
Joint description of waves and currents applied in a simplified load case
(Journal article, 2018)In order to perform a more accurate analysis of marine structures, joint probability distributions of different metocean parameters have received an increasing interest during the last decade, facilitated by improved ... -
Joint Distribution of Environmental Condition at Five European Offshore Sites for Design of Combined Wind and Wave Energy Devices
(Journal article; Peer reviewed, 2015)The design of wind turbines requires information about joint data for wind and wave conditions. Moreover, combining offshore wind and wave energy facilities is a potential way to reduce the cost of offshore wind farms. To ... -
Joint Electrical and Acoustic Measurements for Unfrozen Water Content in Frozen Soil
(Master thesis, 2019)Innholdet av frossent vann bestemmer den mekaniske, termiske og hydrauliske egenskapene til den frosne bakken. Denne oppgaven foreslår å bruke en elektrisk og akustisk målemetode med en tilhørende ledningsmodell for å ... -
Joint Environmental Data at Five European Offshore Sites for Design of Combined Wind and Wave Energy Devices
(Chapter; Peer reviewed, 2013)The costs for an offshore wind farm, especially with bottom fixed foundations increase significantly with increasing water depth. If costs can be reduced to a competitive level, the potential for wind farms in deep water ... -
Joint maintenance and controller reconfiguration policy for a gradually deteriorating control system
(Journal article, 2017)This paper tackles the maintenance decision-making of gradually deteriorating control systems. The main feature of these systems is their ability within a closed-loop to drive actuators in order to set the controlled process ... -
Joint Maintenance Interval and Spare Parts Optimization using a Discrete-Event Simulation Model
(Master thesis, 2015)The goal of this report is to use discrete-event simulation (DES) as a method for optimizing maintenance strategies, such as spare parts levels and maintenance intervals. Firstly, the au- thor argues for spare parts ... -
Joint Optimization of Oil Well Placement and Controls
(Journal article; Peer reviewed, 2012)Well placement and control optimization in oil field development are commonly performed in a sequential manner. In this work, we propose a joint approach that embeds well control optimization within the search for optimum ... -
Joint optimization of performance-based contracting, condition-based maintenance and spare parts inventory for degrading production systems
(Journal article; Peer reviewed, 2024)As a novel supporting approach, performance-based contracting (PBC) ties the service supplier’s compensation to the performance outcome of the system owned by the customer. It enables the service supplier to implement an ... -
Joint Optimization of Well Placement and Controls for Petroleum Field Development
(Doctoral thesis at NTNU;2014:369, Doctoral thesis, 2014)In this thesis we optimize the drilling location and operational controls of wells in a joint manner to improve the overall development strategy for a petroleum field. In particular, in this thesis we treat the integrated ... -
Joint Probability Distribution of Environmental Conditions for Design of Offshore Wind Turbines
(Chapter; Peer reviewed, 2017)The design process for offshore wind turbines includes a fatigue life evaluation of the structure with the relevant environmental conditions at the specified wind farm location. Such analyses require long-term distributions ... -
Joint Rock Physics Inversion of Seismic and Electromagnetic Data for CO2 Monitoring at Sleipner
(Master thesis, 2018)The Carbon Capture and Storage project that is taking place at the Sleipner field involving the injection of CO2 into Utsira sandstone reservoir at 1012 m below sea level. The migration of CO2 must be monitored to understand ... -
Jordfeil i ROV-Umbilical: Effekten av Statisk og Dynamisk lastkarakteristikk
(Master thesis, 2013)DOF Subsea innehar en rekke ROV-systemer plassert på ulike fartøy rundt om i verden. Det er ønskelig at disse systemene skal ha høyest mulig tilgjengelighet, slik at undervannsoperasjoner kan gjennomføres uten at feil på ... -
Jordmodeller og utmatning av fritthengende stigerør
