  1. 1. Study of semi-empirical methods for ship resistance calculations

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Emil Petersson; [2020]
    Keywords : ;

    Abstract : In the early ship design process a quick overview of which shipdesign that could be the optimal choice for the intended usage needsto be investigated. Therefore the feasibility and accuracy ofinterpolating between measurement data from model resistance serieswhen estimating unknown hulls were conducted. READ MORE

  2. 2. Efficient seakeeping performance predictions with CFD

    University essay from KTH/Marina system

    Author : Benjamin Lagemann; [2019]
    Keywords : added wave resistance; CFD; Courant-adapted time step; Euler ˛flow; FINE Marine; inviscid flow; k-ω SST-Menter; KVLCC2; RANS; regular waves; seakeeping; sub-cycling acceleration; time discretization; viscous flow;

    Abstract : With steadily increasing computational power, computational fluid dynamics (CFD) can be applied to unsteady problems such as seakeeping simulations. Therefore, a good balance between accuracy and computational speed is required. READ MORE

  3. 3. Parametric Hull Form Variation and Assessment of Seakeeping Performance

    University essay from KTH/Marina system

    Author : Aina Pons Roser; [2018]
    Keywords : ;

    Abstract : This Master Thesis is about the assessment of the seakeeping performance of different ships subjected to hull parametric variations. The latest version of the potential flow CFD software Shipflow in combination with a CAD platform (CAESES) have been used to carry out the evaluations. READ MORE

  4. 4. Relationship between Shear-Wave Velocity and Consolidation Parameters of Peat

    University essay from Lunds universitet/Geoteknik; Lunds universitet/Institutionen för byggvetenskaper

    Author : Oskar Markström; [2018]
    Keywords : shear wave velocity; peat; constant rate of strain; consolidation parameters; von Post; Technology and Engineering;

    Abstract : There is a need of developing methods for evaluating material parameters for peat. It is hard and costly to obtain undisturbed samples for laboratory testing of the peat. Therefore, in this thesis the possibility of using in situ measurements of the shear wave velocity for first order estimates of the consolidation parameters has been investigated. READ MORE

  5. 5. Super Duplex Stainless Steel Surfaces and their Effects on Marine Biofouling

    University essay from

    Author : Adrian Falk; [2017]
    Keywords : Marin tillväxt; superduplex; bottenfärg; havstulpaner;

    Abstract : Some of the world’s most ancient, but still viable, organisms have since the beginning of maritime caused problems for the industry. The problems affect both the longlivety and efficiency of ships which is caused by the mere presence of organisms attached to the ship hulls. READ MORE
