En omfattande omflaggning av svenska fartyg har pågått under en längre tid. Tidigare har det främst berört andra segment av den svenska sjöfarten, men det senaste året har trenden med omflaggning även spridit sig till färjor. Syftet med denna studie har varit att kartlägga vilka utmaningar som finns med att bedriva färjesjöfart under svensk flagg och hur framtiden kan komma att se ut för svenska sjöbefäl inom färjesjöfarten. Kartläggningen gjordes genom intervjuer med fem representanter från rederier inom färjenäringen. Det gjordes även två kompletterande intervjuer med en representant från en facklig organisation och med ett aktivt sjöbefäl inom färjenäringen. Resultatet visade relativt entydigt att den främsta utmaningen för rederierna idag är bemanningskostnaden, både vad gäller de svenska avtalen och lönenivån i Sverige. Resultatet visade vidare att svenska sjöbefäl i framtiden troligen kommer få arbeta under mindre fördelaktiga avtal än de som finns idag, inte minst för att sådana avtal finns att tillgå i andra högkostnadsländer i närområdet, men att deras kompetens och kunnande värderas högt. / Change of Swedish ships’ nationality has been an ongoing process for several years. Even though this earlier concerned other segments of the Swedish maritime industry, the changing of a ship’s nationality is now common also amongst ferries. The purpose of this study was to find out what challenges there are in running ferries registered in Sweden. The purpose also included finding out how the future might look for Swedish maritime officers within the ferry industry. The study is based on interviews with five representatives from Swedish ferry companies and two additional interviews with a representative from a Swedish union for Swedish maritime officers and a Swedish maritime officer working in the ferry industry today. The result showed that the biggest challenge for the ferry industry in Sweden today is the cost of labor. This includes both the Swedish agreements and salary levels in Sweden. The result also showed that Swedish maritime officers in the future probably will have to accept working under other agreements less profitable than those existing today, especially as this kind of agreements can be found in other countries in the Baltic Sea Area. It also showed that Swedish maritime officers are highly respected for their competence and knowledge.

The purpose of this thesis is to investigate air quality in the James Bay neighbourhood of Victoria, BC, Canada, and determine the effects of emissions from cruise ships and ferries on local air quality. A combination of field monitoring and air quality modeling conducted during the 2007 cruise ship season in Victoria is used to achieve this objective. Pollutants examined include nitrogen dioxide (NO2), sulphur dioxide (SO2) and particulate matter (PM2.5 and PM10). Field monitoring provides long-term average concentration levels throughout the area, while the California Puff Model (CALPUFF) is used to predict concentrations from ferry and cruise ship sources at shorter time periods (1-hour and 24-hour). The two methodologies used for this research quantify air quality in James Bay and establish a baseline of concentration levels which can be referred to during any future air quality studies in the area. Results show possible, yet infrequent, exceedences of Capital Regional District and World Health Organization 1-hour NO2 and 24-hour SO2 air quality guidelines in the study domain. The potential implications of these exceedences on health of residents will be assessed by the Vancouver Island Health Authority.

Small open-deck roll-on/roll-off passenger ferries in Indonesia have a poor safety record. The Indonesian Government is interested in means by which the safety of these vessels can be improved, and this was the main catalyst for commencing research in this area. Any solution should be capable of being retrofitted to both existing vessels and new designs to improve their stability and, hence, their safety. The research therefore focused on the intact stability of the bare hulls, and with addition of side casings, for the vessels for which data was made available by the Indonesian Government. The research covered both quasi-static analysis, based on the objective of meeting the IMO intact stability criteria, and a dynamic approach using time-domain simulation in regular beam waves. A parametric study of the stability parameters of the twenty vessels demonstrated that, without the presence of side casings, the vessels had difficulties in complying with the IMO intact stability criteria. The problems were solved by introducing side casings (watertight spaces above the vehicle deck) either inboard of the vessel’s side-shell plating, or partially inboard and partially outboard of the side shell. The minimum extent (breadth) of side casings required was determined by iteration on each of the twenty vessels, incorporating variations in the height of the centre of gravity and loading conditions. The implementation of the minimum side casings showed that each vessel then met the IMO intact stability criteria. However, the assessment of the vessels’ dynamic stability characteristics using time-domain simulation provided inconsistent results for these vessels with side casings which met the IMO intact stability criteria. For some particular conditions, the existence and the different forms of side casings could decrease vessel survivability by increasing the roll motion amplitudes for both inside and outside casings and could lead the vessel to capsize. The results of the dynamic stability analysis also confirmed the vulnerability of small vessels with small stability parameters to large waves, and the different roll seakeeping behavior of the different vessel stability parameters.

Master of Arts / This work is the history of a particularly singular and strong human enterprise. Until the advent of several more recent interpretative works, Australian transport historiography has heavily emphasised engineering and operational development without examining the contextual social and economic forces. The Manly Ferry, with its unique contribution to the history of Sydney's development as a suburban city, provides a distinctive microcosmic example with which to illustrate the evolution of an urban society - with its emphasis on mobility - in the wake of the industrial revolution.

The maritime transport sector makes a significant contribution to greenhouse gas (GHG) emissions, playing a consistent and increasing part in global CO2 emissions. Electrification of marine transportation is a key and necessary step for achieving the goals of the Paris Agreement and for avoiding the worst consequences of climate change. Sweden is among the first countries pleading for zero-emission transportation within 2045. However, one of the key challenges facing the widespread adoption of electric boats is the availability and efficiency of charging infrastructure.  Wireless power transfer technology with more focus on inductive power transfer technology in the marine sector was investigated. The focus is wireless charging infrastructure for passenger ferries in Goteborg. Vesta was the ferry chosen for the case study and it operates on the Saltholmen to Vrångö route. The route, schedule, and ferry energy consumption were investigated to implement the wireless charging infrastructure. Swot analysis was performed to show the strengths, weaknesses, opportunities, and threats of the research. Based on this investigation, the power profile, energy storage, and adopted solution with its system were proposed.
