      In the salmon industry chemical delousing is done by enclosing the cage in a tarpaulin, and then mixing the chemical agent in the enclosed water volume. Correct dosage is important to obtain the wanted effect, and in order ...
    • 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 ...
    • 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
