1. 6. Överdäckningar – En analys av dagens riskhanteringsproblematik inom denna allt vanligare stadsbyggnadsstrategi

   Master-uppsats, Lunds universitet/Riskhantering (CI)

   Författare :Marcus Ahlström; [2021]
   Nyckelord :Risk management; risk analysis; risk evaluation; road tunnel; railway tunnel; dangerous goods; overbuilding; spatial planning; Technology and Engineering;

   Sammanfattning : The concept of road- and railway overbuilding is an increasingly popular method to use in spatial planning to get rid of physical barriers and create exploitable areas for residential, commercial, and recreational development. Despite the many benefits the method entails, it also brings a lot of problems and challenges regarding risk management with the main issue being how to evaluate and manage risks with extremely low probability and catastrophic consequences.

3. 7. Electrically powered manoeuvring of water jets

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

   Författare :Joel Engström; [2021]
   Nyckelord :Bachelor thesis; Thesis; Mechanical engineering; Uppsala University; Design; Product development; Marine Propulsion; Electrical Actuator; Water Jets; Water Jet Propulsion; Water Jet Manouvering; Steer-by-wire; Marine Technology; Examensarbete; Maskinteknik; Kandidatuppsats; Uppsala Universitet; Konstruktion; Design; Produktutveckling; Vattenjet; vattenjetaggregat; Elektrisk Manövrering; Steer-by-wire; Marinteknik;

   Sammanfattning : A shift towards electric and hybrid propulsion within the marine sector create new challenges for conventional water jet units manoeuvred by hydraulic systems. The high efficiency in high speed water jet crafts benefit from being powered by electricity but will be compromised by constantly running hydraulic pumps, draining available electric capacity on-board.

4. 8. Modular and Flexible Payload Arrangement : With Reconfigurable Floors and Sliding Bulkheads

   Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Liban Mohamed Hassan; Haris Hodzic; [2021]
   Nyckelord :Trendwatching; DNV-GL; Parametric CAD; Concept development; Cargo management;

   Sammanfattning : Background The shipbuilding trends have changed from being single purpose ships only to using modular and flexible parts or systems to carry out multiple missions with as few ships as possible to minimize the ecological and economic impact. A flotilla can become smaller by having multiple ships capable of carrying out various missions instead of single-purpose ships. LÄS MER

5. 9. Strength assessment of rig foundations for a sailing car carrier

   Master-uppsats, KTH/Lättkonstruktioner

   Författare :Alfred Rapaport; [2020]
   Nyckelord :Naval Architecture; Solid Mechanics; Finite Element Analysis; Concept development; Sailing; Skeppsbyggnad; Hållfasthetslära; Finita elementmetoden; Konceptutveckling; Segling;

   Sammanfattning : The wPCC project (wind powered car carrier) is carried out by Wallenius Marine, KTH Royal Institute of Technology and SSPA Sweden. By developing a car carrier mainly propelled by the wind, the emissions are estimated to be reduced by up to 90 %. This thesis deals with the structural aspects of the design. LÄS MER

7. 10. En bogvisirmodell : Underlag för ett PLC styrt bogvisir

   M1-uppsats, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

   Författare :Felix Turhede; Vladimir Suskin; [2018]
   Nyckelord :Bow visor; Bow ports; Bow doors; Estonia; Herald of Free Enterprise; Bogvisir; Bogport; Bogdörrar; Bogöppningar; Estonia; Herald of Free Enterprise;

   Sammanfattning : Syftet med den här studien har varit att presentera ett underlag till konstruktion av en bogvisirmodell som skall kunna gå att styras med en PLC-enhet och som kan användas i undervisningssyfte för PLC-programmering. Underlaget förankrades i verkligheten genom en fältstudie och en litteraturstudie. LÄS MER
