Determination of coverage and thickness of marine growth is a useful tool for determining structural loads and drags on marine structures and ships. In this work, we present an algorithmic program based on sonar and optical camera measurements, that estimates both the coverage and thickness of marine-fouling on off-shore structures. The marine-fouling composition is estimated using a Deep-Neural Network, trained using supervised methods, which can distinguish between hard/soft fouling species and the background water and structural components. The marine-fouling thickness is estimated using an HF Forward Looking Sonar, which is applied as a sensitive ultrasonic thickness gauge, when combined with a thickness measurement algorithm. Combined the measurements provide a localized estimate of the marine-fouling coverage and loadings across the structural surfaces, which can be used for automatic inspection evaluation and mission planning.
The purpose of this project is therefore to develop a software tool that can implement an automated intelligent registration (artificial intelligence) of the catch of cod on board the vessel. The project can both support the ongoing camera projects, but also functions as a forward-looking method where the concept of this approach is that the camera focuses on the catch and can be implemented without human supervision. This has a number of potential advantages, including that human supervision is avoided, the number of cameras can probably be reduced to just one (although possibly a stereo camera), labor resources are saved by automated monitoring, it will be possible to reduce the amount of data, fishermen can target selective fishing based on the information obtained, increased precision in relation to possible legal
use of the observations and overall it will reduce costs. The project supports the monitoring that has been initiated in the Kattegat, but should also be seen as a future development, including internationally, where the focus is on building monitoring/surveillance around the use of images as documentation of the catch. An extremely important element of the project is to create a high-quality dataset that can be used internationally to improve algorithms and intensify research.
This chapter assesses the role of state-owned enterprises (SOEs) in ports and shipping. Insights from regulatory economics are used to identify industry characteristics under which the SOE model is expected to be effective. With the use of these insights, characteristics of ports, terminals and shipping services that may lead to the establishment of SOEs are identified. The empirical overview of SOEs in shipping and ports shows a rather large use of SOEs, especially in container terminal operations and port development. The use of SOEs particularly in port development can be well understood with insights from regulatory economics. The majority of SOEs in ports, terminals and shipping are active internationally. This raises important additional research questions, most importantly regarding the strategic rationale of SOE internationalization and the role of geopolitical considerations in international activities.
The ongoing shift toward a circular economy, in which end-of-life (EOL) products are reused, remanufactured, or recycled, has major implications for seaports, especially seaports in metropolitan areas, as in such areas, huge amounts of EOL products are available. Ports are therefore relevant locations for circular economy activities. This chapter identifies the main commodities in volume terms and the set of associated activities and assesses resulting opportunities and threats for ports. Case studies of Dutch ports are used to illustrate this analysis.
This PhD theis focuses on identifying the opportunities and challenges that on-board maintenance and practical operation of vessels poses in the development of autonomous ships. Inspired by the rapid development of autonomous vehicles considerable effort and interest is now invested in the development of autonomous ships. So far however, most of the research has focused on the legal aspect of unmanned vessels and on developing a system enabling a vessel to operate within the maritime collision regulation without human interaction. Specifically, the theisi looks into three research questions: (1) How is autonomous technology going to affect the workload required for operating and maintaining modern cargo vessels? (2) How is autonomous technology going to affect the operational patterns of the vessels? And (3) How is autonomous technology going to affect the reliability and utilization rate of the vessels?
The study is planned in cooperation between Svendborg International Maritime Academy (SIMAC) and University of Southern Denmark.
This report presents the AEGIS roadmap for automated waterborne transport and is the result of the work related to Task 2.5 Roadmap for waterborne logistics redesign as defined in the AEGIS Grant Agreement. The task was to collect the results of the AEGIS work package 2 and 6, and the AEGIS use cases, to provide a publicly available roadmap for the redesign of more sustainable waterborne transport. Furthermore, the main AEGIS solutions that can be used to realize the redesign were to be identified, and benefits and possible costs were to be described, exemplified by future transport systems, including intercontinental transport. Furthermore, the focus was to be on unitized cargo (ie, containers and ro-ro trailers).
The report is based on the AEGIS use cases and outlines one logistics redesign for short sea shipping where the cargo is containers, and one for inland waterways shipping where the cargo is roro trailers. Intercontinental transport was not studied in detail within the AEGIS project, as it was not in scope. This means that no study investigating the applicability of AEGIS solutions for intercontinental transport has been done, and thus the background for creating a roadmap for intercontinental transport is missing. Instead, intercontinental transport is briefly discussed in a separate section of the report. Furthermore, even though the AEGIS solutions do not target the deep sea leg of intercontinental transport, they are highly applicable to the distribution and consolidation of cargo in the hinterland. For this part of intercontinental transport, the short sea and inland transport roadmaps are directly applicable.
For each of the two segments short sea and inland waterways, the bassline "as-is" scenarios are discussed to provide insight into current challenges and areas with potential for improvements. Then a redesign is introduced, where the AEGIS innovations and concepts are used to gain efficiency benefits and zero emission transport systems. As part of the redesign discussion, the gaps towards realization are also discussed and identified. These are related to immature technology, certain issues that are currently not addressed and need both research and development, and issues related to uptake and investment risk. Next, one roadmap for short sea shipping and one for inland waterways is presented, and discussed in terms of short term, medium term and long term phases and what advancements need to be made (ie, what gaps need to be closed) within each of these periods. Finally, policy support and actions are discussed in terms of what will be required to realize the roadmaps.
The two roadmaps presented in this report include discussions for the short-, medium- and long-term periods. The roadmaps are structured this way to facilitate a discussion around which aspects are mature, and which require more research and has a longer expected horizon to market. The roadmaps are written with the purpose of allowing the implementation of the new transport systems in the short, medium and long term, and a discussion is made around the sustainability of the transport system at each maturity level.
What is the role of the sea in globalized capitalism? In their new book Capitalism and the Sea: The Maritime Factor in the Making of the Modern World, Liam Campling and Alejandro Colás explore this question through a historical and geographical lens. In this book, the authors track the larger history of maritime commerce and pursue new understandings of the role of the sea in the global economy. In doing so, they illuminate the understudied maritime spaces, systems, and flows that underpin the global economy and create the foundations of global material circulation.
Once known as an example of state collapse, Somali territories today see a number of competing public administrations, which, as this book argues, depend on a dynamic trade sector for revenues. Riffing on Tilly’s idea that ‘war makes states,’ the authors argue instead that ‘trade makes states,’ that the facilitation and capture of commodity flows have been instrumental in making and unmaking state-projects across the Somali territories. The volume draws on multi-sited research of everyday economic life along trade corridors in Somali East Africa, including parts of Kenya and Ethiopia. It examines how government officials, informal traders, militias, local businessmen, international investors, and donors feed into systems of regulatory control in ports, at marketplaces, and along transport corridors. Contributions to the volume draw attention to the ingenuities of transnational Somali trade and the ‘politics of circulation,’ providing important insights into contemporary state formation on the margins of global supply chain capitalism.
The energy system needs a range of forecast types for its operation in addition to the narrow wind power forecast that has been the focus of considerable recent attention. Therefore, the group behind the former IEA Wind Task 36 Forecasting for Wind Energy has initiated a new IEA Wind Task with a much broader perspective, which includes prospective interaction with other IEA Technology Collaboration Programmes such as the ones for PV, hydropower, system integration, hydrogen etc. In the new IEA Wind Task 51 (entitled "Foreacsting for the Weather Drive Energy System") the existing Work Packages (WPs) are complemented by work streams in a matrix structure. The Task is divided in three WPs according to the stakeholders: WP1 is mainly aimed at meteorologists, providing the weather forecast basis for the power forecasts. In WP2, the forecast service vendors are the main stakeholders, while the end users populate WP3. The new Task 51 started in January 2022. Planned activities include 4 workshops. The first will focus on the state of the art in forecasting for the energy system plus related research issues and be held during September 2022 in Dublin. The other three workshops will be held later during the 4-year Task period and address (1) seasonal forecasting with emphasis on Dunkelflaute, storage and hydro, (2) minute-scale forecasting, and (3) extreme power system events. The issues and conclusions of each of the workshops will be documented by a published paper. Additionally, the Recommended Practice on Forecast Solution Selection will be updated to reflect the broader perspective.
The safety of people and cargo onboard is a key functionality of a commercial ship.
The health and well-being of seafarers and passengers is protected through an extensive set of technical specifications, standards and norms that govern the design and commissioning of all vessels.
They differ by ship type and size, while the specific services to be provided and the specific geographic regions to be served also play an important role in this respect.
The requirements are of national and international character and vary also with the classification society that will commission the ship. Thus in a broader sense, all competences related to ship design are related one way or another to maritime health.
Much of the design of ships is overseen by a naval architect or marine engineer. It is rare to have the involvement of a medical professional except in the cruise industry.
Purpose and tasks
To ensure that the design of a ship includes the requirements to protect the health and well being of seafarers. More specifically, to identify areas of intervention that go beyond the usual engineering curricula where, nonetheless, the safety dimension is embedded through international standardization.
