Experimental investigation of drag and lift forces on hydroid fouled nets
Teige, Maria (Master thesis, 2019)Marine begroing vokser på nett som brukes til oppdrett, og det er et alvorlig problem for bransjen. Det påvirker fiskens helse og velferd, og i tillegg fører den til større belastninger på notposen. Hydroiden Eructra ... -
Experimental study of an offshore aquaculture cage concept
Voldsund, Maria (Master thesis, 2023)Behov for bærekraftig matproduksjon øker betydelig i takt med en økt global befolkning og global oppvarming. Nye klimavennlige løsninger må integreres og utvikles for å møte den økende etterspørselen etter mat, hvor ... -
Geometry and Kinematics of Breaking Waves
Lader, Pål Furset (Dr. ingeniøravhandling, 0809-103X; 2002:32, Doctoral thesis, 2002)The objective of this thesis is to experimentally study different breaking waves cases. This is done by measuring in detail the free surface geometry and the internal kinematics of the waves as they approach breaking. Three ... -
Hydrodynamic Loads on Net Panels With Different Solidities
Føre, Heidi Moe; Endresen, Per Christian; Norvik, Carina; Lader, Pål Furset (Journal article; Peer reviewed, 2020)Drag forces on nets represent the largest contribution to hydrodynamic loads on traditional fish farms, and will have a large impact on total loads on new designs utilizing netting as containment method. Precise methods ... -
Influence of internal rotational flow on wave response of a flexible closed containment system
Dreyer Moe, Preben (Master thesis, 2022)Denne oppgaven studerte påvirkningen av en intern rotasjonsstrøm på bølgeresponsen til en lukket fleksibel merd. Eksperimentelle tester ble utført på en modell i en skala 1:30. Modellen besto av en elastisk flyter, ... -
Modeling of Hydroelastic Response of Closed Flexible Fish Cages due to Sea Loads
Strand, Ida Marlen (Master thesis, 2013)Norway is presently the worlds biggest producer of Atlantic salmon. The traditionally used open-net-structures are probably the most important reason for the Norwegian success.The very nature of aquaculture, where fish is ... -
Numerical and Experimental Study on the Seakeeping Behavior of Floating Closed Rigid Fish Cages
Kristiansen, David; Lader, Pål Furset; Endresen, Per Christian; Aksnes, Vegard Øgård (Chapter, 2018)The present paper addresses the seakeeping behavior of a rigid type of floating closed fish cages, with focus on effects of sloshing on the coupled motions and mooring loads. Closed cages have gained much attention recently ... -
Numerical study of closed rigid fish cages in waves and comparison with experimental data
Su, Biao; Tsarau, Andrei; Endresen, Per Christian; Kristiansen, David; Lader, Pål Furset (Journal article; Peer reviewed, 2021)Closed fish cages have gained increased interest in marine aquaculture. However, knowledge on the seakeeping behaviour of a floating closed cage and the influence of the contained water inside the cage are still limited. ... -
Operational limits for aquaculture operations from a risk and safety perspective
Yang, Xue; Ramezani, Ramin; Utne, Ingrid Bouwer; Mosleh, Ali; Lader, Pål Furset (Peer reviewed; Journal article, 2020)Current decision making regarding whether to abort a high-risk aquaculture operation in a Norwegian fish farm is mainly experience-driven. The on-site personnel decides whether to start/delay/abort operations primarily ... -
Passive Oscillating Foils for Additional Propulsion under Calm Conditions
King, Marlene Judith Taranger (Master thesis, 2019)Denne masteroppgaven tar for seg ulike konsepter som kan bidra til å øke hastigheten til the Ocean Cleanup sitt pilot prosjekt, System 001. Ettersom systemet opererer i Stillehavet, mellom Hawaii og California, var det ... -
Produksjonsanlegg for rur
Gjørtz, Truls Victor (Master thesis, 2019)For å utvikle et konsept for produksjon av rur er det først utviklet rammebetingelser. De er delt inn i biologiske og tekniske betingelser. De biologiske betingelsene gjør rede for rurens forhold til natur og miljø. Fjærerur, ... -
Random wave-induced current in shallow water using deep-water wind and wave statistics
Myrhaug, Dag; Lader, Pål Furset (Peer reviewed; Journal article, 2020)This paper addresses the random wave-induced current in shallow water based on deep-water wind and wave statistics, where the wave-induced current is expressed in terms of the deep-water seastate wave parameters, significant ... -
Review of cage and containment tank designs for offshore fish farming
Chu, Yunil; Wang, Chien Ming; Park, Jeong-Cheol; Lader, Pål Furset (Journal article, 2020)Fish farm operators worldwide are planning to move offshore due to lack of available nearshore production sites in heavily utilized coastal zones, where there is increasing community opposition to coastal development and ... -
Sloshing in a rotating liquid inside a closed sea cage for fish farming
