Dynamic Response Analysis of Floating Storage Tank System Considering Hydrodynamic and Mechanical Interactions
Wan, Ling; Zhang, Chi; Magee, Allan Ross; Jin, Jingzhe; Han, Mengmeng; Ang, Kok Keng; Hellan, Øyvind (Chapter, 2018-06-25)For better utilization of ocean and coastal space, hydrocarbon products can be stored in the floating tanks, which can be enclosed by barge system. The barge system can be moored through pile foundations. The tanks are ... -
Experimental Study of Hydrodynamic Responses of a Single Floating Storage Tank With Internal Fluid
Chi, Zhang; Magee, Allan R.; Ling, Wan; Wang, Chen Ming; Hellan, Øyvind (ASME Digital colletion;OMAE2017-61867, Chapter, 2017-06-25)When floating structure with internal fluid compartment is close to other structures, the multibody interaction problem needs to be addressed in addition to the internal fluid influence. Furthermore, shallow water effects ... -
Global dynamic response analysis of oil storage tank in finite water depth: Focusing on fender mooring system parameter design
Wan, Ling; Han, Mengmeng; Jin, Jingzhe; Zhang, Chi; Magee, Allan Ross; Hellan, Øyvind; Wang, Chien Ming (Journal article; Peer reviewed, 2018-01-15)A modular floating concept for oil storage is proposed. The concept is composed of several modular floating tanks and barges. The floating tanks are self-stable and designed for storage of oil and hydrocarbon material. The ... -
Hydrodynamic Model Tests With a Large Floating Hydrocarbon Storage Facility
Fonseca, Nuno; Chi, Zhang; Rodrigues, José Miguel; Ren, Nianxin; Hellan, Øyvind; Magee, Allan R. (OMAE2019;96761, Chapter, 2019-06)The paper presents model tests with a floating hydrocarbon storage facility performed in SINTEF Ocean’s basin. The system may be considered a very large floating structure with a footprint of 300m × 310m. Hydrocarbons are ... -
Hydroelastic response of concrete shells during impact on calm water
Abrahamsen, Bjørn Christian; Grytten, Frode; Hellan, Øyvind; Søreide, Tore H.; Faltinsen, Odd Magnus (Peer reviewed; Journal article, 2023)Many ocean structures located offshore are supported by large vertical concrete columns. High and steep storm waves – in the process of breaking – may induce large local slamming loads on these columns. The present work ... -
Hydroelastic response of Froude scaled stiffened steel panels exposed to design-critical wave slamming
Abrahamsen, Bjørn Christian; Grytten, Frode; Andreassen, Erik; Hellan, Øyvind (Peer reviewed; Journal article, 2023)Stiffened steel panels of offshore ocean structures may experience violent wave impacts which needs to be accounted for in design. The slamming pressures are often measured in scaled wave tank tests and imposed on finite ... -
Initial Design of a Double Curved Floating Bridge and Global Hydrodynamic Responses Under Environmental Conditions
Wan, Ling; Magee, Allan Ross; Hellan, Øyvind; Watn, Arnstein; Ang, Kok Keng; Wang, Chien Ming (ASME Digital colletion;OMAE2017-61802, Chapter, 2017)In this paper, a floating bridge concept is proposed. This bridge concept comprises a two oppositely curves in plan, which enables the cancellation of the axial forces at the bridge as one arch will be under compression ... -
Internal Fluid Effect Inside a Floating Structure: from Frequency Domain Solution to Time Domain Solution
Jin, Jingzhe; Magee, Allan Ross; Han, Mengmeng; Hoff, Jan Roger; Hermundstad, Elin Marita; Hellan, Øyvind; Wang, Chien Ming (ASME Proceedings | Ocean Engineering;OMAE2017-62228, Chapter, 2017-06-25)Liquid inside a floating structure influences both hydrostatic and hydrodynamic response of the floating structure. Some examples of floating structure with internal liquid are: vessels with roll damping tanks, floating ...
