Analysis of spar and semi-submersible floating wind concepts with respect to human exposure to motion during maintenance operations
(Peer reviewed; Journal article, 2022)Floating offshore wind turbines (FOWTs) are expected to experience onsite maintenances and inspections during their lifetimes. To carry out offshore maintenance activities, a crew will be transferred to an FOWT and spend ... -
Assessment of operational limits : Effects of uncertainties in sea state description
(Peer reviewed; Journal article, 2021-02)For operations dominated by waves, operational limits are normally expressed in terms of allowable sea state parameters, such as the significant wave height (Hs) and spectral peak period (Tp). The allowable sea states need ... -
Dynamic response analysis of a catamaran installation vessel during the positioning of a wind turbine assembly onto a spar foundation
(Journal article; Peer reviewed, 2018-05-11)Installation of floating wind turbines is a challenging task. The time and costs are closely related to the installation method chosen. This paper investigates the performance of an efficient installation concept – a ... -
Flow around two elastically-mounted cylinders with different diameters in tandem and staggered configurations in the subcritical Reynolds number regime
(Peer reviewed; Journal article, 2021)Flow around two cylinders with different diameters undergoing Flow-Induced Vibrations (FIV) in the subcritical flow regime is investigated using two-dimensional Unsteady Reynolds Averaged Navier-Stokes (URANS) approach. ... -
Joint description of waves and currents applied in a simplified load case
(Peer reviewed; Journal article, 2018-03)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 ... -
Numerical modelling of hydrodynamic responses of Ocean Farm 1 in waves and current and validation against model test measurements
(Peer reviewed; Journal article, 2021)With the continuous growing of the aquaculture industry and increasingly limited fish farming sites at close to shore areas both in Norway and worldwide, there is a need to develop fish farms suitable for aquaculture ... -
Numerical simulation of piggyback pipelaying under current loadings
(Peer reviewed; Journal article, 2023)For piggyback pipelaying operations, current-induced force and its effect on the piggyback pipe have not been thoroughly studied. In the present study, an improved method in hydrodynamic load calculation and structural ... -
An object-oriented method for fully coupled analysis of floating offshore wind turbines through mapping of aerodynamic coefficients
(Peer reviewed; Journal article, 2021-07)This work presents a novel object-oriented approach to model the fully-coupled dynamic response of floating offshore wind turbines (FOWTs). The key features offered by the method are the following: 1) its structure naturally ...
