Lund-Tønnesen, Magnus (Master thesis, 2018)The offshore industry is facing many challenges when it comes to maintaining operational efficiency. One of the biggest problems is related to flow assurance problems. To avoid such issues, different chemicals are transported ... -
Subsea Drilling and Well Construction Cost Model
Sund, Rikke Breivik (Master thesis, 2020)Avgjørelser tas gjennom hele livssyklusen til et felt, der den største muligheten til å påvirke kostnadene er i de tidligste fasene. Det er derfor viktig å ta nøyaktige beslutninger i planleggingsfasene av feltutvikling. ... -
Subsea Field Layout Optimization
Liu, Haoge (Doctoral theses at NTNU;2022:33, Doctoral thesis, 2022)This study focuses on building a systematic method for the subsea field layout optimization with the aim of minimizing the overall field development cost. The subsea field layout optimization is a very complex problem which ... -
Subsea field layout optimization (Part I) – directional well trajectory planning based on 3D Dubins Curve
Liu, Haoge; Gjersvik, Tor Berge; Faanes, Audun (Peer reviewed; Journal article, 2022)Directional well trajectory planning, which includes the optimization of the drilling site location and the trajectory between the drilling site to the completion interval, plays an important role in reducing subsea field ... -
Subsea field layout optimization (part II)–the location-allocation problem of manifolds
Liu, Haoge; Gjersvik, Tor Berge; Faanes, Audun (Peer reviewed; Journal article, 2022)The location-allocation problem of manifolds, which is a part of subsea field layout optimization, directly affects the flowline cost. This problem has always been studied as a mixed-integer nonlinear programming (MINLP) ... -
Subsea field layout optimization (part III) --- the location-allocation problem of drilling sites
Liu, Haoge; Gjersvik, Tor Berge; Faanes, Audun (Peer reviewed; Journal article, 2022)This study proposes an efficient method to optimize the subsea field layout with the aim of minimizing the subsea field development cost, based on the two methods introduced in Part I and Part II for solving the well ... -
Subsea templates for operation with subsea drones
Haukeland, Håvard Moberg (Master thesis, 2021)The next generation of subsea inspection, maintenance and repair (IMR) vehicles are drones capable of operating both autonomously and under human control. Many different technologies are required for the drones to as an ... -
System Design for the Next Generation Subsea IMR Vehicles
Henriksen, Eirik Hexeberg (Doctoral theses at NTNU;2018:196, Doctoral thesis, 2018)This thesis is about how to unlock the full potential of unmanned underwater vehicles to save cost and increase quality in inspection maintenance and repair (IMR) services for subsea petroleum extraction equipment. Today ... -
The Cost Model of Subsea Production Systems and Flowlines including Automatic Flowline Routing
Musayev, Shamsi (Master thesis, 2020)Nowadays, optimization of field development projects in a cost-efficient way is one of the crucial topics in the petroleum industry. The current economic conditions and unpredictable fluctuations of oil price force all ... -
The Traveling Circus - Automated generation of parametric wellbore trajectories minimizing wellbore lengths for different subsea field layouts
Lillevik, Eirin; Standal, Ingvild Evensen (Master thesis, 2018)It is known from the media that Equinor is trying a new generation of unmanned wellhead platforms on the Oseberg field. According to them, this will cut costs dramatically. The reason is that dry well components are used. ... -
Trajectory control, kick-detection and friction test: Transitioning to an automated drilling system.
Hiwa, Arman; Mannsverk, Jonas; Meyer, Vilde Romslo (Master thesis, 2020)Denne masteroppgaven var originalt tiltenk å dekke Fase 2 av Drillbotics konkurransen.
