  1. 1. Studies on future Mine Countermeasure Vessels (MCMV)

    University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskap

    Author : Philip Somehagen; [2023]
    Keywords : Concept development; Mine countermeasure vessels; ROV; Sonar; Konceptutveckling; Minjaktsfartyg; ROV; Sonar;

    Abstract : Background Maritime transportation is vital for international trade, and any disruption to this flow can have severe financial and environmental consequences. Ship mines, both old and new, present significant risks as man-made obstacles. READ MORE

  3. 2. Real-time Optimal Braking for Marine Vessels with Rotating Thrusters

    University essay from KTH/Matematik (Avd.)

    Author : Sigurlaug Rún Jónsdóttir; [2022]
    Keywords : Nonlinear optimization; nonlinear optimal control; numerical optimal control; real-time solution; optimal braking; receding horizon; modeling; ship model; propeller forces; rudder forces; direct multiple shooting method; discretization;

    Abstract : Collision avoidance is an essential component of autonomous shipping. As ships begin to advance towards autonomy, developing an advisory system is one of the first steps. An advisory system with a strong collision avoidance component can help the crew act more quickly and accurately in dangerous situations. READ MORE

  4. 3. Sensor system for pressure measuring over a sail : Construction and implementation of a sail pressure measuring system

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Filip Palm; [2022]
    Keywords : Oceanbird; Sail pressure; KTH; pressure sensor system; Environment; Oceanbird; tryckmätningssystem; miljö; KTH; tryckmätning segel;

    Abstract : Wallenius Marine, KTH and SSPA are working together on a wind powered car carrier, that will ship cars over the atlatic. KTH has a small scale prototype of this vessel, and uses this prototype to test performance and new sensor systems, that can be used on the full scale vessel. READ MORE

  5. 4. Autonomous Docking of an Unmanned Surface Vehicle using Model Predictive Control

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Sofia Kockum; [2022]
    Keywords : Technology and Engineering;

    Abstract : Autonomous docking of marine vessels presents challenges different from the ones faced when travelling at open sea or in an archipelago. External disturbances due to the varying environment and accurate positioning at low speed are examples of these kinds of challenges. READ MORE

  6. 5. Development and study of noise generation from propellers

    University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Author : Anton Anton Dunström; Fredrik Skjernov; [2022]
    Keywords : Silent propellers; Propeller development; Noise generation; Skew angle; Blade Area Ratio; Openprop; NATO STANAG no. 1136; Swedish defense and Research Agency FOI ; James Fisher Defense.; Tysta propellrar; Propellerutveckling; Ljudskapande; Skevningsvinkel; Bladtäckningsarea; Openprop; NATO STANAG no. 1136; FOI; James Fisher Defense.;

    Abstract : Noise generation from underwater activities propagates into the marine environment.For marine vessels the propulsion system generates the most noise during itsoperations. Naval vessels that want to operate without being detected want to controlthe sound generating properties of the vessel. READ MORE
