A simplified analytical method for predictions of ship deckhouse collision loads on steel bridge girders
(Journal article; Peer reviewed, 2018)Bridges across busy navigation channels are under the threat of accidental ship collisions. Many research works have been conducted to investigate the structural responses during ship bow-bridge pier collisions. However, ... -
Discussion of assumptions behind the external dynamic models in ship collisions and groundings
(Journal article; Peer reviewed, 2019)In the past decades, a prevailing way for the assessment of responses in ship collisions and groundings has been to decouple the problem into two parts: external dynamics and internal mechanics. The external dynamics deals ... -
Dynamic behaviour of aluminium alloy plates with surface cracks subjected to repeated impacts
(Journal article, 2018)This paper investigates the behaviour of aluminium alloy plates with and without initial cracks under repeated impacts. Three series of impact tests were conducted to study the behaviour of circular plate that do not have ... -
Laboratory experiments on shared-energy collisions between freshwater ice blocks and a floating steel structure
(Journal article; Peer reviewed, 2017)Ship collisions with floating ice in which the ship sustains damage are in the shared-energy regime – both the ice and the ship dissipate energy through inelastic deformations. The physics of these events are rarely studied. ... -
Numerical investigations of the dynamic response of a floating bridge under environmental loadings
(Journal article; Peer reviewed, 2018)Floating bridges across wide and deep fjords are subjected to the environmental wind and wave loadings. In this study, the dynamic response of floating bridges under such loadings is investigated. A floating bridge concept, ... -
Quantitative risk modelling in the offshore petroleum industry: integration of human and organizational factors
(Journal article; Peer reviewed, 2019)In-depth investigations of major offshore accidents show that technical, human, operational and organisational risk influencing factors (RIFs) all have crucial effects on the accident sequences. Nonetheless, the current ... -
Short-term extreme ice loads prediction and fatigue damage evaluation for an icebreaker
(Journal article; Peer reviewed, 2018)In this paper, the short-term extreme value statistics of the ice loads acting on ship hull and the fatigue damage due to ice loads actions are studied. Due to the stochastic nature of the ice-induced loads and randomness ... -
Thermal analysis of marine structural steel EH36 subject to non-spreading cryogenic spills. Part I: experimental study
(Peer reviewed; Journal article, 2021)Liquefied Natural Gas (LNG) spills may cause steel to embrittle, leading to the brittle fracture of marine structures due to the cryogenic temperatures. For the integrity assessment of marine steel structures in the event ... -
Thermal analysis of marine structural steel EH36 subject to non-spreading cryogenic spills. Part II: finite element analysis
(Peer reviewed; Journal article, 2021)In Part I of this paper, six liquid nitrogen (LN2) pool boiling tests were carried out to locally cool down six different EH36 steel plates to cryogenic temperatures. Leindenfrost and Critical Heat Flux (CHF) points of LN2 ... -
Thermal analysis of marine structural steel EH36 subject to non-spreading cryogenic spills: Part III: structural response assessment
(Peer reviewed; Journal article, 2022)An experimental study that allows for thermal-structural analysis of steel structures subject to non-spreading cryogenic spills is described. A local, non-spreading cryogenic spill was replicated by building a liquid ...
