Automatic image segmentation for boundary detection of apparently connected sea-ice floes
Zhang, Qin; Skjetne, Roger; Su, Biao (Chapter, 2013)Ice concentration, ice types, and floe size distribution are three important factors in the analysis of ice-structure interaction in a broken ice field. The use of cameras as sensors for offshore operations in ice-covered ... -
Autonomous Monitoring and Inspection Operations with UUVs in Fish Farms
Kelasidi, Eleni; Su, Biao; Caharija, Walter; Føre, Martin; Pedersen, Magnus Oshaug; Frank, Kevin (Peer reviewed; Journal article, 2022)In this study, a general control framework for autonomous operations in highly complex and dynamically changing environments such as fish farms is proposed and experimentally validated. Since fish farms feature an environment ... -

A Digital Twin is in essence a digital representation of an asset that provides better insight into its ... -
Experimental and Numerical Investigation of a Double-Acting Offshore Vessel Performance in Level Ice
Su, Biao; Skjetne, Roger; Berg, Tor Einar (Journal article; Peer reviewed, 2014)In this paper a numerical model and experimental data are used to investigate the level ice performance of a double-acting intervention vessel. The icebreaking capability and maneuverability in level ice are analyzed by ... -
Farmed Atlantic salmon (Salmo salar L.) avoid intrusive objects in cages: The influence of object shape, size and colour, and fish length
Zhang, Qin; Bloecher, Nina; Evjemo, Linn Danielsen; Føre, Martin; Su, Biao; Eilertsen, Espen; Mulelid, Mats Aarsland; Kelasidi, Eleni (Peer reviewed; Journal article, 2024)Underwater vehicles and other mobile platforms are seeing increased use as tools within fish farming, particularly due to current trends towards Precision Farming practices, and more exposed farming sites. Although many ... -
An integrated approach for monitoring structural deformation of aquaculture net cages
Su, Biao; Kelasidi, Eleni; Frank, Kevin; Haugen, Joakim; Føre, Martin; Pedersen, Magnus Oshaug (Peer reviewed; Journal article, 2021)The majority of present marine finfish production is conducted in flexible net cages which can deform when they are subjected to water movements generated by currents. The ability to monitor net deformation is important ... -
Machine learning based digital twin framework for aquaculture net cage system
Skauen, Håvard (Master thesis, 2022)I denne master oppgaven er det presentert et rammeverk for digital tvilling for fiskeoppdrettsanlegg ved å bruke numerisk simulering, maskin læring og sensor data. De numeriske simuleringene er utført med programvaren FhSim ... -
Modeling of Remotely Operated Vehicle (ROV) Operations for Aquaculture
Skaldebø, Martin Breivik; Amundsen, Herman Biørn; Su, Biao; Kelasidi, Eleni (Journal article, 2023)This paper proposes an extensive model for unmanned underwater vehicle operations in aquaculture and includes a dynamic 6 degrees of freedom (DOF) quaternion-based model of a remotely operated vehicle (ROV) and a model of ... -
Numerical assessment of a double-acting offshore vessel's performance in level ice with experimental comparison
Su, Biao; Skjetne, Roger; Berg, Tor Einar (Journal article; Peer reviewed, 2014)In this paper a numerical model is used to investigate the level ice performance of a double-acting intervention vessel, and the results are compared with a limited set of experimental data. The icebreaking capability and ... -
Numerical modelling of hydrodynamic responses of Ocean Farm 1 in waves and current and validation against model test measurements
Jin, Jingzhe; Su, Biao; Dou, Rui; Luan, Chenyu; Li, Lin; Nygaard, Ivar; Fonseca, Nuno; Gao, Zhen (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 ... -
Numerical Predictions of Global and Local Ice Loads on Ships
Su, Biao (Doktoravhandlinger ved NTNU, 1503-8181; 2011:154, Doctoral thesis, 2011)Ice loads represent the dominant load for ice-going ships, and it is important to estimate both global and local ice loads on ship hulls. The global ice load governs the ship’s overall performance in ice, and it is an ... -
