Observations of bridge stay cable vibrations in dry and wet conditions: A case study
(Peer reviewed; Journal article, 2021)The characteristics of wind- and rain-wind-induced vibrations of bridge stay cables are studied by using ambient vibrations records acquired on a cable-stayed bridge. Mean wind speed and wind-cable angle, as well as the ... -
Offloading operation bivariate extreme response statistics for FPSO vessel
(Peer reviewed; Journal article, 2023)The Floating Production Storage and Offloading unit (FPSO) is an offshore unit producing and storing crude oil prior to tanker transport. An important design concern is an accurate prediction of risky dynamic hawser tensions ... -
Offshore tethered platform springing response statistics
(Peer reviewed; Journal article, 2022)This paper demonstrates the validity of the Naess–Gadai method for extrapolating extreme value statistics of second-order Volterra series processes through application on a representative model of a deep water small size ... -
Offshore Wind Turbine Loads and Motions in Unstable Atmospheric Conditions
(Peer reviewed; Journal article, 2019)Even though it is widely known that unstable atmospheric stability conditions can lead to higher turbulence, the use of proper turbulent wind models considering unstable conditions are not often used in the simulation of ... -
Offshore wind turbine wake characteristics using scanning doppler lidar
(Journal article; Peer reviewed, 2017-10)Within an offshore wind park, wind flow characteristics are quite complex and govern both the energy production and the structural wind turbine response. An experimental study focussed on assessing the spatial variability ... -
Oil tanker under ice loadings
(Peer reviewed; Journal article, 2023)As a result of global warming, the area of the polar pack ice is diminishing, making merchant travel more practical. Even if Arctic ice thickness reduced in the summer, fractured ice is still presenting operational risks ... -
On Competition-driven Teaching of Multidisciplinary Engineering Education: Implementation cases at University of Stavanger
(Peer reviewed; Journal article, 2017)This article will reflect the experience gained on problem-based learning (PBL) projects implemented in the last six years at University of Stavanger (UiS). The PBL projects were implemented by establishing two ”student-driven” ... -
On the three-dimensional effects of the water entry of wedges
(Peer reviewed; Journal article, 2023-09)Three-dimensional (3D) effects on the total and spanwise slamming coefficients and the pressure reductions acting on the wedge surface during water entry are modeled in a unified manner. First, the water entry of wedges ... -
On the wake flow behind a sphere in a pipe flow at low Reynolds numbers
(Peer reviewed; Journal article, 2020-10)Numerical simulations are carried out to investigate the flow around a stationary sphere in a pipe. Seven sphere diameters d = 0.1D–0.9D (D is the diameter of the pipe) are chosen to investigate the effects of the blockage ... -
On-Bottom Stability of Umbilicals and Power Cables for Offshore Wind Applications
(Peer reviewed; Journal article, 2019)With the increase in offshore wind farms, the demands for umbilicals and power cables have increased. The on-bottom stability of umbilicals and power cables under the combined wave and current loading is the most challenging ... -
Operational reliability study of ice loads acting on oil tanker bow
(Peer reviewed; Journal article, 2023-04)As a result of climate change, the Arctic glaciers start to melt, and the summer season arrives, making it acceptable for trade ships. There is still shattered ice in the saltwater even though the Arctic glaciers melt in ... -
Optimal Rotary Wind Turbine Blade Modeling with Bond Graph Approach for Specific Local Sites
(Peer reviewed; Journal article, 2022-09)The wind turbine blade is an important component for harnessing wind energy. It plays a vital role in wind turbine operation. In this work, a study was conducted to investigate the dynamic behavior of an optimal rotary ... -
Overview study on challenges of additive manufacturing for a healthcare application
(Peer reviewed; Journal article, 2021)Additive manufacturing is a rapidly evolving manufacturing technology bringing numerous and wide opportunities for the design team involved in the process by creating intricate and customized products with saving labor, ... -
Parametric study of different unbonded tendon layouts in pre-stressed concrete flat plates
(Peer reviewed; Journal article, 2020-11)Post-tensioned unbonded tendons are widely used in fat slabs/plates when there is a demand for large span lengths, durable tendons and a reduction in the weight of structure. For post-tensioned fat slab/plates, diferent ... -
Pedestrian Wind Comfort Assessment Using Computational Fluid Dynamics Simulations With Varying Number of Wind Directions
(Peer reviewed; Journal article, 2022-07)The construction of a building inevitably changes the microclimate in its vicinity. Many city authorities request comprehensive wind studies before granting a building permit, which can be obtained through Computational ... -
Pipeline shore crossing approaches in Arctic conditions
(Peer reviewed; Journal article, 2019)The development of the Arctic region will entail the construction of new infrastructure, in particular, subsea pipelines. Considering the lack of actual field practice, ecosystem vulnerability and lack of common Arctic ... -
