  1. 1. Sensitivity Study of Semisubmersible Motions to Hull Form Parameters and Their Optimisation

    Master-uppsats, KTH/Marina system

    Författare :Elin Ogeman; [2014]
    Nyckelord :;

    Sammanfattning : An optimisation routine is developed to find the optimal size of a semisubmersible regarding the seven geometrical variables, column radius, column draught, pontoon height, pontoon beam, horizontal column distance and total underwater beam. Depending on the user’s input, the objective function consists of both heave, roll and pitch motions in several different wave directions. LÄS MER

  3. 2. Modelling of Elastic Ship in Waves

    Master-uppsats, KTH/Marina system

    Författare :Manohara Ranganath Draksharam; [2012]
    Nyckelord :;

    Sammanfattning : Ships in the seas undergo different distortions like bending, twisting or combined bending and twisting. The demand for increase in length and speed of the ships is increasing due to this the study for flexibility of structures is becoming important. LÄS MER

  4. 3. Vibration mitigation for High Speed Craft

    Master-uppsats, KTH/Marina system

    Författare :Katrin Olausson; [2012]
    Nyckelord :;

    Sammanfattning : The crew of small, high-speed marine craft (HSC) is exposed to high levels of vibrations and shocks that can imply risks for adverse health effects. The working environment needs to be improved by appropriately isolating the crew from the severe, non-linear accelerations that characterise the motions of small HSCs. LÄS MER

  7. 5. Manoeuvrability model for a Pure Car and Truck Carrier

    Master-uppsats, KTH/Marina system

    Författare :Daniel Zachrisson; [2011]
    Nyckelord :;

    Sammanfattning : This is a master thesis conducted during the autumn and winter 2010-2011 at KTH Centre for Naval Architecture in collaboration with Wallenius Marine AB. Traditionally the hull lines of typical Pure Car and Truck Carriers have been optimized for minimum resistance when going on a straight path and for maximum cargo capacity. LÄS MER
