1. 1. Evaluation of IMO second-generation intact stability criteria and examination of different fishing vessel designs to dead ship condition and excessive acceleration failure mode

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Pavlos Liatsis; [2023]
   Nyckelord :Ship Design; Second Generation Intact Stability Criteria; Excessive Acceleration; Fishing Vessels; Skeppsdesign; andra generationens intakt stabilitetskriterier; kraftiga acceleration; fiskefartygsskrovs;

   Sammanfattning : The main objective of this project is to investigate the applicability of the IMO second-generation intact stability criteria in enhancing the process of designing fishing vessels, which often face stability challenges due to their narrow hulls and harsh operating environments. The study involves analyzing the impact of these criteria, specifically focusing on dead ship conditions and Level 1 and Level 2 excessive acceleration criteria, on the design of three fishing vessels.

3. 2. Assessing Efficiency and Cognitive Load in Form Navigation for Operators in Combat Management Systems

   Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Omid Mircoram; Niklas André; [2022]
   Nyckelord :;

   Sammanfattning : In naval warfare, warships often need to perform several tasks simultaneously in an unpredictable fast-paced environment. Combat-related tasks are performed by operators in a Naval Combat Management System (NCMS). The challenging environment places high demands on the operators’ ability to work efficiently. LÄS MER

4. 3. Development and study of noise generation from propellers

   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Anton Anton Dunström; Fredrik Skjernov; [2022]
   Nyckelord :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.;

   Sammanfattning : 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. LÄS MER

5. 4. Introduction of UXV assets into naval fleet architectures through an MILP based fleet modelling tool

   Master-uppsats, KTH/Marina system

   Författare :Sjoerd Jan Sinnema; [2021]
   Nyckelord :Numerical cost optimization; Naval fleet modelling; UXV integration; MILP programming; Maritime engineering; Numerisk kostnadsoptimering; flottmodellering; UXV -integration; MILP -programmering; sjöfartsteknik;

   Sammanfattning : The problem of fleet design and fleet modelling; for decades problems regarding determining fleet sizes and optimized routing problems have formed the groundwork into the fleet design and fleet optimization for a wide range of business sectors. In most of these problems only single entities or fixed design resources are optimized for a certain route and delivery objective based on minimizing operational costs. LÄS MER

7. 5. Robust naval localization using a particle filter on polar amplitude gridmaps

   Master-uppsats, KTH/Optimeringslära och systemteori

   Författare :Carl Schiller; [2021]
   Nyckelord :Amplitude gridmap; particle filter; position monitoring; marine navigation.; Amplitudrutnätskartor; partikelfilter; positionsestimering; marin navigation.;

   Sammanfattning : Maritime navigation heaviliy relies on GNSS and related technologies for positioning and navigiation. Since these technologies are vulnerable to external threats such as signal spoofing, alternatives are needed for backup purposes. LÄS MER
