Experimental investigation of a closed vertical cylinder-shaped fish cage in waves
Shen, Yugao; Firoozkoohi, Reza; Greco, Marilena; Faltinsen, Odd Magnus (Peer reviewed; Journal article, 2021)Wave-induced response of a closed floating fish cage consisting of a vertical circular cylinder with an external toroidal floater is studied theoretically and experimentally. A main purpose was to investigate how the ... -
Implementation of Linear Potential-Flow Theory in the 6DOF Coupled Simulation of Ship Collision and Grounding Accidents
Yu, Zhaolong; Shen, Yugao; Amdahl, Jørgen; Greco, Marilena (Journal article, 2016)Ship collisions and groundings are highly nonlinear and transient, coupled dynamic processes involving large structural deformations and fluid structure interactions. It has long been difficult to include all effects in ... -
Numerical and experimental investigations on mooring loads of a marine fish farm in waves and current
Shen, Yugao; Greco, Marilena; Faltinsen, Odd Magnus; Nygaard, Ivar (Journal article; Peer reviewed, 2018)A realistic aquaculture fish farm system in both regular and irregular waves is investigated by numerical simulations and model tests. The main purpose is to develop a reliable numerical tool and in this respect to investigate ... -
Numerical study of a well boat operating at a fish farm in current
Shen, Yugao; Greco, Marilena; Faltinsen, Odd Magnus (Journal article; Peer reviewed, 2019)Dynamic response of a well boat operating at a fish farm in current is investigated numerically. An objective is to determine the operational conditions of the well boat. In terms of the fish farm, a realistic set-up (with ... -
Numerical study of a well boat operating at a fish farm in long-crested irregular waves and current
Shen, Yugao; Greco, Marilena; Faltinsen, Odd Magnus (Journal article; Peer reviewed, 2019)The dynamic response of a coupled well boat–fish farm system in irregular long-crested waves and current is analyzed numerically in the time domain. The main purpose is to investigate the influence of the well boat on the ... -
Numerical study towards closed fish farms in waves using two Harmonic Polynomial Cell methods
Shen, Yugao; Greco, Marilena; Faltinsen, Odd Magnus; Ma, Shaojun (Chapter, 2020)In order to avoid salmon lice and minimize environmental pollution, closed fish-farm concepts are gaining increasing attention in Norway. Violent sloshing of the water inside the closed cage then becomes an important issue ... -
Operational limits for floating-collar fish farms in waves and current, without and with well-boat presence
Shen, Yugao (Doctoral theses at NTNU;2018:367, Doctoral thesis, 2018)Dynamic response of a floating circular collar-type fish farm, without and with well-boat presence, in current, regular and irregular waves is analyzed. A modern design well boat and a realistic fish farm (with single cage) ... -
Wave and Current Effects on Floating Fish Farms
Faltinsen, Odd Magnus; Shen, Yugao (Journal article; Peer reviewed, 2018)The paper is partly a review on hydrodynamic and structural aspects of fish farms. In addition, new numerical results are presented on the stochastic behavior of bending stresses in the floater of a realistic net cage in ...
