  1. 1. Towards sustainable shipping: Recommendations for the telescopic mast design of a sailing cargo vessel

    University essay from KTH/Lättkonstruktioner

    Author : Lukas Blau; [2021]
    Keywords : Oceanbird; telescopic mast; conceptual design; sailing cargo vessel;

    Abstract : A comparative study is carried out to investigate the most promising route towardsthe lightweight construction of a retractable mast for a sailing cargo vessel.Four design families are developed and compared. The primary criteria forjudgment are the structural mass, strength, and stiffness in relation to a providedbenchmark design. READ MORE

  3. 2. The Wake Effect and Wind Farm Clustering

    University essay from Lunds universitet/Institutionen för energivetenskaper

    Author : Igor Ciric; [2021]
    Keywords : wake effect impact; wake mitigation measures; farm to farm wakes; Southern Middle Bank; wind farm clustering; Technology and Engineering;

    Abstract : The wind energy industry is growing rapidly and as offshore wind expands in the Baltic sea, more and more clusters will be observed. The purpose of this work is to better understand the impact that wakes have on the electricity production for wind farm clusters in the Southern Middle Bank region. READ MORE

  4. 3. Electrically powered manoeuvring of water jets

    University essay from Uppsala universitet/Industriell teknik

    Author : Joel Engström; [2021]
    Keywords : 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;

    Abstract : 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.

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

    University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Lättkonstruktioner

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

    Abstract : 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. READ MORE
