Green Labelling a Sea Voyage using Real Time Data
Full text linkA case study research design of a sea voyage between Port A and Port B was chosen for this study. The goal was to identify challenges and bottlenecks of sea-going activities inside and between ports. The purpose is to contribute to the body of knowledge regarding green labelsin the maritime industry, as well as contributing to identifying parameters for a green framework. Three interviews were conducted: with the port authority of Port B, a VTS System Supplier, and a Norwegian environmental organization. In addition, secondary data sources were studied from Port A. An extensive literature review was carried out, analysed thematically to identify consistency of related research. The findings from the industry and the literature were eventually compared with the aim of identifying similarities and potential knowledge gaps between industry and research.
The findings suggest that challenging areas within maritime shipping can be related to regulatory, collaborative, standardization, and motivational factors. In terms of regulations, barriers, stopping sustainable progression, were identified in charter parties, encouraging shipowners and operators to sail full speed to port, rather than at economical speed, despite long anchorage times in ports. The maritime industry consists of complex stakeholder environments, where stakeholders represent different interests and financial models. Collaboration would increase communication, data sharing, and potentially increase efficiency. In ports, the visiting vessels, terminals, and VTSOs collect different data, which, if shared, could allow the stakeholders to make more efficient decisions. Standardization of parameters to measure environmental performance, methodologies, measuring- and analytical tools is vital to ensure that the market conditions are equal. Data sharing and different data formats are outlined as a cut barrier for adopting green frameworks. The maritime industry is known for its conservativity, suggesting that implementing innovations can be difficult. The motivational factors outlined in this study relates to reluctance of sharing and collaborating, “watch-and-wait” attitude, and business-as-usual approaches.
While many of the industry findings correlated with the literature findings, there were some differences, especially related to motivational factors for adopting green labels. Additionally, findings suggests that when conducting studies in the maritime industry, one should have a holistic view, where different stakeholder opinions are considered, to ensure the complexity of the industry is embraced
Situational awareness preparation in maritime navigational watch handover
Full text linkThis master's thesis explores navigators' time allocation and routines for preparation for establishing situational awareness before taking watch duties on ships. Through qualitative semi-structured interviews, the study investigates six navigators' practices through one-to-one interviews. The focus is on their preparation time to establish situational awareness before watch, assessment of time aspects and factors involved in night vision, as well as the use of checklists during watch handovers. The empirical findings were then compared with the study’s relevant theoretical framework.
The main findings of the study reveal variations both in time and routines in how navigators prepare for their watch duties, suggesting potential for improvement in optimizing time allocation to achieve better and faster situational awareness. The study also suggests a lack of knowledge regarding time factors related to night vision and situational awareness among navigators. Furthermore, the study uncovers considerable variations in the use of standardized checklists and highlights their practical ineffectiveness for navigators.
This study opens a new research area focusing on the time window from when the navigator arrives on the bridge until they take over watch duties. The study highlights a need for further research to better understand navigators' practices and needs related to establishing situational awareness before assuming watch duties on ships. It also recommends increased focus on training, personal dark adaptation measuring, and awareness about night vision, as well as more frequently revision of the use and content of watch handover checklists to improve safety and efficiency establishment of situational awareness in maritime operations
Autonomous ships and sustainability.
Full text linkThis literature review aims to analyze and comprehend the MASS (Maritime Autonomous Surface Ships) and if there is a relationship with sustainability, what characteristics and elements can be considered more sustainable against the manned ships, understand what are the most important forces that are moving the development of this kind of ship, and what would be the possible economic benefits of the implementation of this technology in the maritime industry.This literature review aims to analyze and comprehend the MASS (Maritime Autonomous Surface Ships) and if there is a relationship with sustainability, what characteristics and elements can be considered more sustainable against the manned ships, understand what are the most important forces that are moving the development of this kind of ship, and what would be the possible economic benefits of the implementation of this technology in the maritime industry
Maritime Workforce Transition: Competence and Training Needs in Maritime Electrification and Zero-Emission Transition
Full text linkDenne oppgaven undersøker hvordan elektrifisering i maritim sektor påvirker kompetansebehov og opplæring blant arbeidstakere og interessenter. Gjennom kvalitative intervjuer med norske havner og en fergeoperatør avdekkes hvilke utfordringer og barrierer som finnes ved overgangen til elektriske fartøy. Studien viser et økende behov for digital og teknisk kompetanse, samtidig som mangelen på standardiserte opplæringsprogrammer og klare internasjonale regler skaper usikkerhet. Oppgaven foreslår bedre samarbeid om utdanning, tydeligere kommunikasjonsstrategier og internasjonal standardisering for å sikre en rettferdig og effektiv overgang
Navigating collaboration: Exploring the dynamics between civilian and military project managers in complex projects from the contractor’s perspective
Full text linkIt is no secret that there have been challenges regarding complex projects regarding time and resource use within the public sector. Military procurement is one of those. Often, it can be prescribed to leadership or challenges in planning. This thesis takes a look at the challenges around cooperation between the parties involved in defence procurement. This thesis aims to analyse how differences between actors impact the success of defence procurement projects.
It uses examples and data from various projects and militaries, most predominant in this thesis, the United States and Norway, to explain the challenges through a qualitative and inductive approach. Through a critical literature review to build up a framework of knowledge and challenges for this thesis, and semi-structured interviews of five respondents within a phenomenological methodology to get a perspective on a project manager's lived experiences within the defence sector in Norway.
By analysing these findings, a pattern emerged that there are challenges in cooperation between the two sides. Though the military is a highly regarded and respected leadership institution, it is regarded as a very good cornerstone for the background of leaders. From the private sector perspective, project managers (PM`s) suggest that their military counterparts have an insufficient background to take on such a complex responsibility when assigned this duty. And adding factors such as a too rigid and complex bureaucracy as a challenge. The surprise was that NATO military leadership training, such as in Norway, emphasises that dynamic and proactive leadership styles (Operational leadership) seem to be checked by bureaucracy and inexperience, making these leaders passive and rigid. This hinders progress compared to the private sector, which relies heavily on dynamic and experienced PM`s. Private sector rules and regulations are a challenge, but as a group, they have more formal experience in project work and are not similarly bound by these constraints. This, in turn, creates a misalignment in their experience level, organisation, and culture that presents a challenge when collaborating.
This research can be used as an argument to delve deeper into the theme of inter- organisational cooperation challenges between the public and private sectors in the defence sector. It does not provide an answer but contributes to a deeper exploration of inefficiencies and offers insights into possible challenges and solutions to mitigate waste through improved stakeholder collaboration
Improving Internal Handover Processes in Offshore Shipping: A Case Study of Island Offshore AS
No full textIn offshore shipping, the handover between chartering and operations marks a critical transition from commercial planning to execution at sea. This internal process involves the transfer of documentation, responsibility, and operational expectations between departments that often work under different assumptions and time pressures. Despite its importance, the handover phase has received limited academic attention, particularly in the context of offshore supply and project vessels.
This thesis investigates how the handover process is structured and practiced within Island Offshore, a Norwegian offshore shipping company. Through a qualitative case study, the research examines how information flows between chartering, operations, and the vessel and how roles and routines are defined and enacted during this transition.
Empirical data were collected through five semi-structured interviews with personnel from both shore and vessel, complemented by an analysis of internal contract review documents. Thematic analysis was applied to identify recurring patterns and challenges in the handover process.
The findings reveal that although Island Offshore has implemented formal routines such as contract review meetings and digital documentation systems, the success of the handover often depends on informal communication, individual initiative, and shared understanding across departments. Variations between vessel types and project complexity also affect how handovers are carried out in practice.
The study contributes new insights to maritime logistics literature by linking internal coordination challenges to structural and cultural factors. For industry practitioners, the findings suggest that improving handover quality requires better tools and stronger collaboration and early involvement of key personnel across organizational boundaries
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
