Joint Maritime Bunker Hedging and Operational Consumption Based on CVaR Optimization

Maritime shipping is an important driver of global economic growth. Efficient green maritime technologies are critical for both the profitability and sustainability of shipping carriers due to the fact that fuel consumption has already made up 45–55% of the total operational cost of a ship. Moreover, the application of green maritime technologies also challenges the input/output of the maritime industry. Currently, there is a lack of coordination between the two strategies of maritime bunker management: one is the bunker procurement, which is faced with the fierce volatility of bunker fuel prices, and the other is the bunker consumption of vessel operation scheduling with applicable maritime technologies. To address the challenge posed by the new sulfur emission regulations, the two isolated strategies are inefficient. This study presents an integrated model that takes both the financial technology (bunker hedging) and the operational bunker cost efficiency (sailing speed and routing optimization under emission regulations) into account. The objective is to maximize the total rate of portfolio return considering the revenue and the cost simultaneously. By analyzing the Conditional Value at Risk (CVaR) risk measure, we examined the effects of the bunker spot, contract, and hedging in futures markets on the optimal joint solution. Numerical results from a real-world case study show that the optimized integrating financial and operational strategies yield the lowest expected total costs as well as the highest revenue with CVaR constraints. The findings provide a prospect for maritime shipping as an effective decision tool for bunker management under environmental regulations. The management insights of our study will benefit the corporate participants, policy makers, and researchers in liner shipping revenue and risk management.

Accelerating Research and Development in the US Arctic Reflections on a NOAA Program

Since 2015, the Innovative Technology for Arctic Exploration (ITAE) program has supported maritime technology development that contributes to economic growth, ocean health, and ocean management in Alaska. The program does this in multiple ways: through public-private partnerships, platform and small-scale sensor design, and research to operations, commercialization, and application of science-driven technologies. ITAE is a high-risk, high-reward research collaborative that provides support and expertise for creative scientists pursuing highly innovative research solutions with the potential for broad impact in US Arctic marine sciences. This program is funded through NOAA to support projects that may be overlooked in the traditional peer-review process because of their inherent risk. However, not all risks lead to success, not every risk leads to failure, and not all failures eliminate success. Development and growth are nurtured by risk and temporary setbacks. The science advanced by these researchers and collaborators forges new paths of discovery. While the Arctic is an excellent testbed, in part, due to its extreme conditions, the technologies and lessons detailed here are transferable to oceanographic research outside of the Arctic. This paper reviews the program as well as the successes and failures of this dedicated Arctic innovation collaborative at the NOAA Pacific Marine Environmental Laboratory.

Reflections on the Benefits of a Regional Development-Oriented University in Maritime: The Case of Tuzla Region

As universities gain new roles and expectations from them increase, they are transforming to meet them. One of the expectations that has emerged in recent years is that universities should contribute to regional and global development. In order to respond to this expectation, universities have started to engage in various activities, thus helping to revitalize economic, social, and cultural life in their regions. In parallel, some universities in Turkey have been identified as regional development-oriented universities. In this study, the contributions of regional development-oriented universities to their regions are examined in the maritime context and the contributions that a maritime-oriented university with a similar mission can make to the region are discussed. Then, all findings are analyzed under the assumption that a university located in the Tuzla district is designated as a regional development-oriented university in the maritime field. It is concluded that such a university can contribute in many areas from the dissemination of maritime culture to the training of new stakeholders for the increasingly important maritime trade, from pollution prevention to the development of maritime technologies.

Can a ship be its own captain? Safe manning of autonomous and uncrewed vessels

New maritime technologies -autonomous and uncrewed vessels- are already poised to revolutionize the shipping industry. However, they are virtually unregulated under the current maritime laws, which raises significant safety and social impact issues. Can their incorporation into the maritime legal order occur through a policy decision by the international community or are substantial amendments to existing laws or adoption of new international legal instruments necessary? While the possibility of expanding the notions of a master, seafarer, vessel and safe manning requirements under the existing international framework is analyzed, it is concluded that the adoption of a new, specialized autonomous and uncrewed vessels convention or a specialized code designed for those vessels seems a much easier and faster solution.

OCEANOGRAPHIC ENVIRONMENTAL ASSESSMENT USING UNDERWATER GLIDERS

REP(MUS) 21 is an annual exercise jointly organised by the Portuguese Navy, the University of Porto, NATO’s Centre for Maritime Research and Experimentation (CMRE) and the NATO Maritime Unmanned Systems Initiative. The exercise gives Allies and NATO partners a chance to field and evaluate new maritime technologies. A Rapid Environmental Assessment warfare group was formed using Maritime Unmanned Systems to perform an environmental assessment of this area, by collecting data from the upper ocean region (0- 200 m.), sea surface, littoral shallow waters, and river estuary. Underwater Gliders were used in the REPMUS21 exercise, brought by several partners, to conduct environmental observations from the underwater domain of the exercise’s Joint Operations Area (JOA). This paper focuses on the use of SeaExplorer underwater gliders to collect oceanographic data during the exercise, and the operational impact of using this knowledge to compile the Recognized Environmental Picture of the exercise area.

AIS Trajectories Simplification Algorithm Considering Topographic Information.

With the development of maritime technology and equipment, most ships are equipped with an automatic identification system (AIS) to store navigation information. Over time, the size of the data increases, rendering its storage and processing difficult. Hence, it is necessary to transform the AIS data into trajectories, and then simplify the AIS trajectories to remove unnecessary information that is not related to route shape. Moreover, topographic information must be considered because otherwise, the simplified trajectory can intersect obstacles. In this study, we propose an AIS trajectory simplification algorithm considering topographic information. The proposed algorithm simplifies the trajectories without the intersection of the trajectory and obstacle using the improved Douglas–Peucker algorithm. Polygon map random (PMR) quadtree was used to consider topographic information on the coast, and the intersection between topographic information and simplified trajectories was efficiently computed using the PMR quadtree. To verify the effectiveness of the proposed algorithm, experiments were conducted on real-world trajectories in the Korean sea. The proposed algorithm yielded simplified trajectories with no intersections of the trajectory and obstacle. In addition, the computational efficiency of the proposed algorithm with the PMR quadtree was superior to that without the PMR quadtree.

Boats, Seafaring, and the Colonization of the Americas and California Channel Islands: A Response to Cassidy (2021)

ABSTRACT In a recent issue of California Archaeology, Jim Cassidy (2021. “A Technological Assessment of the North Pacific Seafaring Hypothesis: Informed by California Channel Island Research.” California Archaeology 13 (1): 69–92). provided a flawed assessment of the potential role boats and seafaring played in the initial peopling of the Americas, as well as the nature of watercraft used to settle Santarosae and California’s other Channel Islands. His arguments contain numerous errors and inconsistencies and are based primarily on his previously published interpretation of lithic tools from the Early Holocene component at the Eel Point site on San Clemente Island. Here, we point out the most obvious errors and weaknesses in Cassidy’s arguments and present a more realistic view of what we know and do not know about early seafaring and maritime technology in North America and southern California.

A Primary Research on Legislation of Leading Maritime City Development of Xiamen

Based on the relatively comprehensive evaluation system and definition constructed by Menon Economics and DNV in "The leading maritime cities of the world"[1], the government needs to consider shipping, finance and law, maritime technology, attractiveness&competitiveness when building a global leading maritime city five dimensions. This article will study from a legal point of view, taking Xiamen as a case study.
 If Xiamen wants to build a leading maritime city of the world, the legislation of the sea is an area that cannot be ignored. The Xiamen Municipal Government is very concerned about areas that can significantly increase GDP, such as maritime technology and marine industries. While, insufficient attention has been paid to the Legislation of the Sea. Like Shenzhen's political status, Xiamen is a "Special Economic Zone" and "Independent Planning Status". The Xiamen government enjoys legislative powers beyond that of general cities. However, due to the late start of constructing the Maritime legal system in Xiamen, there are many shortcomings: marine lack of collaboration mechanism, lack of soft power of the maritime rule of law, etc. Therefore, the Xiamen Municipal Government should first understand the importance of the legislation of the sea and then make up for the shortcomings as soon as possible. While reasonably learning from advanced international experience such as British law, we should promote the process of China's "Basic Law of the Sea" legislation and promote the progress of Xiamen's legislation of the sea to promote Xiamen's relevant laws such as sea-related dispute settlement. The establishment of service institutions enables Xiamen to actively participate in the governance of the global marine legal system, enhance the public's awareness of marine legal affairs, and cultivate specialized marine legal elites. (Independent Planning Status： Municipalities with Independent Planning Status under the National Social and Economic Development. ) Under the background of Xiamen's concentrated resources to build the world-leading maritime city, this paper analyzes the challenges faced by Xiamen's marine economic development, combined with China's national strategy. It analyzes the current situation of Xiamen from the perspective of law construction. Learn from experience with U.K. marine-related law. The feasibility of legislation in Xiamen is analyzed.
 The path of law construction is put forward: ① Constructing the legal system of the maritime rule of law; ② Constructing a settlement center for maritime disputes; ③ Paying attention to the global maritime rule of law governance; ④ Enhancing the soft power of the maritime rule of law.
 Legislative suggestions for local governments are put forward: ① Clarify the development orientation of the marine economy; ② Form a planning system and structural layout; ③ Establish an incentive mechanism and supporting measures; ④ Form a financial support service system; ⑤ Formulate safeguard measures for coordinated development; ⑥ Clarify the content of Taiwan cooperation and international development.

정책 네트워크로서의 한중해양협력

This study sheds light on what forms have been developed to institutionalized collaboration over both governments over the maritime boundaries between Korea and China, private maritime cooperation, and the policy network. The focus of this study is to analyze the governments and the main areas and actors of the cooperation of private organizations through the concept of the policy network and suggests the policy measures for the association. Specifically, the process of discussion or policy implementation related to the maritime cooperation between Korea and China led to the following results. First, the maritime cooperation between Korea and China has been promoted by regular conferences and accords between both governments. The discussion of the maritime cooperation between both countries has been diversified in areas and objects, such as regular conferences for the maritime boundaries, and the debate being prompted for the maritime business, science, technologies, nature, and environmental cooperation. Second, the various associates not only the central government but also non-government and private organizations have attempted to seek marine cooperation. According to the private marine organizations, they established marine cooperation comprehensively through long-term joint research and interactions between researchers. This is because private cooperation including the governments has prompted multilateral cooperation and manifested the specific outcomes in the marine science-technology. In other words, this study argues that it is needed to establish a mid-to-long-term and comprehensive maritime government, noting that the areas and actors in marine cooperation in government and private organizations are diversified.

NUMERICAL ANALYSIS SEAKEEPING AND MOTION SICKNESS INCIDENCE (MSI) ON HOSPITAL SHIPS BY ADDING FINS STABILIZER

The development in maritime technology to improve ship performance and operations are growing and diverse. One of the developments carried out is the addition of fin stabilizers to improve ship safety as support for comfort and ships. This research analyzes the effect of variations in the shape of the fin stabilizer on the seakeeping and Comfort Index for Hospital Ships using Maxsurf Modeler software. The parameters used in this research are fins stabilizer Gemini 30, Gemini 50, and modular NR 30. While the variation of ship speed 0, 14, and 18 knots. The direction of the arrival of waves 0, 45, 90, 135, and 180 degrees. Based on data analysis carried out on ship motion, the NR 30 type fin stabilizer is far superior to the others with a maximum value of 4.04- degree roll movement, 0.543- degree pitch movement, and 0.4116 heave acceleration movement. Type NR 30 also has the best comfort on the moderate Motion Sickness Incidence (MSI) Criteria.

Norwegian ship-owners' adoption of alternative fuels

The shipping sector's rising greenhouse gas emissions are often considered “hard-to-abate”. Some ship-owners have recently adopted or started to consider the adoption of alternative fuels, but systematic studies of this are still lacking. We address this gap by studying how ship-owners differ in both actual and intended adoption of alternative fuels. We analyze data from a unique survey with 281 ship-owners in Norway, a major ship-owning country and center for maritime technology development, with descriptive statistics and analysis of variance. We find early adopters among large and established ship-owners in offshore, international cargo and domestic passenger shipping segments, which are often subjected to specific contractual demands for alternative fuel adoption. Laggards were typically small and young ship-owners operating in shipping segments where demands for alternative fuel adoption are weak. Our findings also suggest that firms' business strategy and financial and knowledge resources may have relevance for ship-owner's adoption of alternative fuels. Our study has implications for national and international policymaking, highlighting for example how contracting mechanisms can be an effective tool in incentivizing the adoption of alternative fuels.

A Life Less than Ordinary: The Schooner Ocean (1821\u20131865)

The East Winner Bank Shipwreck takes its name from the southern sandbank on Hayling Island near Portsmouth, UK. Examination of the wreck indicates a 19th-century carvel-built vessel. The sandbank is an active environment, meaning the wreck is rarely exposed to its full extent. Discussed here is work completed on the site before and during the social-distancing restrictions imposed by COVID-19. Documentary sources and previous detailed surveys suggest a possible identification for the wreck. The site appears to be an example of an everyday 19th-century coastal trading vessel, rarely explored archaeologically in the UK, with potential to contribute to discussions of the maritime technologies and maritime cultural landscape of regular folk. The investigation represents an excellent example of combining historical and archaeological data sets to further the interpretation of both sources, revealing details about the ship and its lasting impact on this stretch of coastline.

Elektronik seyir cihazlarının deniz kazalarına etkileri

In recent years, maritime-related organizations and companies have moved to a risk-based approach. To determine the risks, it is necessary to understand comprehensively why accidents occur and how it develops. The most effective measures need to be identified to implement the accident prevention measures successfully. According to the results of scientific studies conducted in the past, 80% of human factors risks were effective in marine accidents. Nowadays, maritime technologies are the most effective method for reducing the risks of human factors. However, the use of electronic navigation devices has not eliminated accidents. In this study, the accident reports for collision and grounding due to the electronic navigation devices' risk was evaluated using Human Factors Analysis and Classification System (HFACS) method. As a result of the study, more than half of the visible (active) causes of accidents have been identified as operating failure factors in electronic navigation equipment. Recommendations to prevent the occurrence of accident factors have been made.
