Design and construction of floating modular photovoltaic system for water reservoirs
Dai, Jian; Zhang, Chi; Lim, Han Vincent; Ang, Kok Keng; Qian, Xudong; Wong, Johnny Liang Heng; Tan, Sze Tiong; Wang, Chien Looi (Journal article; Peer reviewed, 2019)In May 2018, the Housing & Development Board (HDB) of Singapore piloted the first locally-designed 100 kWp floating photovoltaic system at the world’s largest floating photovoltaic cell test-bed in Tengeh Reservoir. This ... -
Effect of modelling inhomogeneous wave conditions on structural responses of a very long floating bridge
Dai, Jian; Stefanakos, Christos; Leira, Bernt Johan; Alsos, Hagbart Skage (Peer reviewed; Journal article, 2021)Floating bridges are suitable for connecting land parcels separated by wide and deep waterbodies. However, when the span of the crossing becomes very long, the water environment exhibits inhomogeneities which introduce ... -
Effect of wave inhomogeneity on fatigue damage of mooring lines of a side-anchored floating bridge
Dai, Jian; Leira, Bernt Johan; Moan, Torgeir; Alsos, Hagbart Skage (Peer reviewed; Journal article, 2020)Mooring systems are important structural components of very long floating bridges. They effectively limit the transverse motions of the bridge under environmental loads. They also add viscous hydrodynamic damping to the ... -
Effect of wave-current interaction on a long fjord-crossing floating pontoon bridge
Dai, Jian; Abrahamsen, Bjørn Christian; Hansen Viuff, Thomas; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)Fjord-crossing floating bridges are sophisticated structures subjected to complex environmental loadings including combined action of wave and current. However, the effect of wave-current action is often neglected in a ... -
Effect of Wave-Current Interaction on Structural Responses of a Very Long and Side-Anchored Floating Bridge
Dai, Jian; Abrahamsen, Bjørn Christian; Leira, Bernt Johan (Chapter, 2020)This paper is concerned with a computational study on the hydroelastic response of a long, straight and side-anchored fjord-crossing floating bridge accounting for the wave-current interaction. The effect of this interaction ... -
Hydrodynamic analysis of partially filled liquid tanks subject to 3D vehicular manoeuvring
Han, Mengmeng; Dai, Jian; Wang, Chien Ming; Ang, Kok Keng (Journal article; Peer reviewed, 2019)This paper is concerned with liquid sloshing in a partially filled container due to 3-dimensional vehicle motion. The liquid sloshing is described by a set of linear modal equations derived from the potential flow theory, ... -
Inhomogeneous wave load effects on a long, straight and side-anchored floating pontoon bridge
Dai, Jian; Leira, Bernt Johan; Moan, Torgeir; Kvittem, Marit Irene (Peer reviewed; Journal article, 2020)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 ... -
Investigation of inhomogeneous wave conditions in Sulafjorden
Stefanakos, Christos; Dai, Jian; Leira, Bernt Johan (Chapter, 2021)Complex fjord topography (bathymetry and coastline) may differentiate significantly wave conditions not only compared with the offshore ones but in the vicinity of few tens of meters. In the present work, possible ... -
Large floating structure with free-floating, self-stabilizing tanks for hydrocarbon storage
Dai, Jian; Ang, Kok Keng; Jin, Jingzhe; Wang, Chien Ming; Hellan, Øyvind; Watn, Arnstein (Journal article; Peer reviewed, 2019)Hydrocarbon is a major source of energy for sustainable development. Storage of hydrocarbon products, however, requires a significant amount of land space to land-scarce countries like Singapore. This paper presents an ... -
Moving element analysis of high-speed train-slab track system considering discrete rail pads
Lei, Tuo; Dai, Jian; Ang, Kok Keng; Li, Kun; Liu, Yi (Peer reviewed; Journal article, 2021)This paper presents a study of the dynamic behavior of a coupled train-slab track system considering discrete rail pads. The slab track is modeled as a three-layer Timoshenko beam. The study is carried out using the moving ... -
Numerical modelling and dynamic response analysis of curved floating bridges with a small rise-span ratio
Wan, Ling; Jiang, Dongqi; Dai, Jian (Peer reviewed; Journal article, 2020)As a potential option for transportation applications in coastal areas, curved floating bridges with a same small specified rise to span ratio of 0.134, supported by multiple pontoons, are investigated in this paper. Two ... -
Structural Response Analysis and Fatigue Damage Estimation of a Floating Bridge Subjected to Inhomogeneous Wave Loads
Dai, Jian; Leira, Bernt Johan; Moan, Torgeir; Alsos, Hagbart Skage (Chapter, 2020)In this paper, a computational study of the structural responses of a floating bridge for crossing of the Bjørnafjord in Norway is presented. The study employs an idealized floating bridge model developed based on the phase ...
