Algorithmic formulation of clay and sand pipe–soil interaction models for on-bottom stability analysis
(Peer reviewed; Journal article, 2021)This paper presents a new algorithmic formulation of the clay and sand pipe–soil interaction models recommended by the DNV-RP-F109 code for dynamic on-bottom stability analysis of submarine pipelines. The pipe–soil force ... -
An anisotropic friction model in non-bonded flexible risers
(Journal article; Peer reviewed, 2018-05)The present paper addresses small scale friction tests and an anisotropic friction model to predict friction for the interface between the anti-wear tape and tensile armors in non-bonded flexible risers. Small scale friction ... -
Analysis and Design of Floating Prestressed Concrete Structures in Shallow Waters
(Journal article; Peer reviewed, 2018-05)Prestressed concrete floating structures have been used for over a century with notable success in various parts of the world. However, there still exist issues related to the analysis and design, and the service performance ... -
Analysis of lifting operation of a monopile for an offshore wind turbine considering vessel shielding effects
(Journal article; Peer reviewed, 2014-12)This study addresses numerical simulations of the lifting operation of a monopile for an offshore wind turbine with a focus on the lowering process. A numerical model of the coupled system of the monopile and vessel is ... -
Design, Modelling and Analysis of a Large Floating Dock for Spar Floating Wind Turbine Installation
(Journal article; Peer reviewed, 2020-07)Installation of floating wind turbines at the offshore site is a challenging task. A significant part of the time efficiency and costs are related to the installation methods which are sensitive to weather conditions. This ... -
Directional wave spectrum estimation with ship motion responses using adversarial networks
(Peer reviewed; Journal article, 2022)The external environmental conditions around a vessel are essential for efficient and safe ship operation, among which the sea state is of key importance. Considering the ship as a large wave buoy, the sea state can be ... -
Friction models for evaluating dynamic stresses in non-bonded flexible risers
(Journal article; Peer reviewed, 2017-09)This paper addresses friction models used for evaluating dynamic stresses in non-bonded flexible risers. A review of the most commonly used methods to model friction between layers in such structures was performed. Four ... -
Inhomogeneous wave load effects on a long, straight and side-anchored floating pontoon bridge
(Journal article; Peer reviewed, 2020-07)In this paper, we present a numerical study on the hydroelastic response of a 4.6 km long fjord crossing floating bridge subjected to wave loads. The bridge is straight in design and supported by 35 pontoons along its full ... -
Low-velocity impact behaviour and failure of stiffened steel plates
(Peer reviewed; Journal article, 2017)The behaviour and failure of stiffened steel plates subjected to transverse loading by an indenter is studied in this paper. Low-velocity dynamic and quasi-static tests of stiffened plates with geometry adopted from a ... -
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 ... -
Stochastic dynamic load effect and fatigue damage analysis of drivetrains in land-based and TLP, spar and semi-submersible floating wind turbines
(Journal article; Peer reviewed, 2015-07)This paper deals with the feasibility of using a 5 MW drivetrain which is designed for a land-based turbine, on floating wind turbines. Four types of floating support structures are investigated: spar, TLP and two ... -
Validation of vessel seakeeping model tuning algorithm based on measurements at model scale
(Peer reviewed; Journal article, 2021)Wave-induced vessel motion prediction plays a critical role in ensuring safe marine operations. The operational limiting criteria can usually be calculated by applying presumed linearized vessel motion transfer functions ...
