With growing pressures on marine ecosystems and on marine space, an increasingly needed strategy to optimize the use of marine space is to co-locate synergic marine human uses in close spatial–temporal proximity while separating conflicting marine human uses. The ArcMap toolbox SEANERGY is a new, cross-sectoral spatial decision support tool (DST) that enables maritime spatial planners to consider synergies and conflicts between marine uses to support assessments of co-location options. Cross-sectoral approaches are important to reach more
integrative maritime spatial planning (MSP) processes. As this article demonstrates through a Baltic Sea analysis, SEANERGY presents a crosssectoral use catalog for MSP through enabling the tool users to answer important specific questions to spatially and/or numerically
weight potential synergies/conflicts between marine uses. The article discusses to what degree such a cross-sectoral perspective can support integrative MSP processes. While MSP integrative challenges still exist, SEANERGY enables MSP processes to move towards developing shared goals and initiate discussions built on best available knowledge regarding potential use-use synergies and use-use conflicts for whole sea basins at once.
The legal limbo that defines the maritime space over which the process of delimitation of the outer continental shelf is applied appears today as an eminently practical question that needs to be addressed. The institutional framework provided by UNCLOS, which establishes the existence of an internationalized space on the seabed - the area - seems limited to respond to a debate that confuses Geology with Law. This article focuses on the powers of the International Seabed Authority as an agency authorized to act on behalf of Mankind by exploring its weaknesses in its exercise of this mandate in the context of that process. By analyzing the conflict between the expansionist goals of States and the embodied principle that gives the Authority the assignment to act on behalf of Mankind in securing a space that, according to the text of the Convention, belongs to it, we conclude that there are apparent inconsistencies in the institutional framework created the Montego Bay Convention. In our exegesis of Part XI of the Convention, we work on the cogent force of that principle and raise questions about the legal legitimacy of the entire process, ie in the absence of a clear statement by the above-mentioned Authority. We conclude that the text of the Convention provides the possibility of a direct intervention by the Authority but that there are still no political conditions for such a possibility to be realised.
This article discusses the development of second ship registers and their interconnections to the policy idea of maritime clusters. Through a narrative of the contemporary history of Danish maritime policy, the article shows how these apparently different policy measures were closely related and together constitute a coherent framework based upon specific values, views of cause–effect relationships, and perceptions of major challenges and their context. Danish maritime policy provides an excellent case for the study of the contemporary history of maritime policy-making. Denmark was among the first of the traditional shipping nations to set up a second register, and the concept of maritime clusters became part of Danish maritime policy before it emerged as a construct in European Union maritime policy. We provide detail on the unfolding of some of the most important recent events in Danish maritime policy and highlight its development as a process of learning that involves the prolonged drafting and fine-tuning of statements and ideas, and the borrowing and adjustment of policy ideas developed elsewhere.
The European Union (EU) seeks to become a global maritime-security actor, yet strategic challenges influence its maritime-security strategy process. Is there a distinctive and coherent EU approach to global maritime security, and how should the EU address the growing range of maritime challenges, including the intensification of militarized competition in the Indo-Pacific?
Maritime transport carries around 80% of the world’s trade. It is key to the economic development of many countries, it is a source of income in many countries, and it is considered as a safe and environment friendly mode of transport. Given its undisputed importance, a question is what does the future hold for maritime transport. This chapter is an attempt to answer this question by mainly addressing the drive to decarbonize shipping, along with related challenges as regards alternative low carbon or zero carbon marine fuels. The important role of maritime policy making as a main driver for change is also discussed. Specifically, if maritime transport is to drastically change so as to meet carbon emissions reduction targets, the chapter argues, among other things, that a substantial bunker levy would be the best (or maybe the only) way to induce technological changes in the long run and logistical measures (such as slow steaming) in the short run. In the
long run this would lead to changes in the global fleet towards vessels and technologies that are more energy efficient, more economically viable and less dependent on fossil fuels than those today. In that sense, it would have the potential to drastically alter the face of maritime transport in the future. However, as things stand, and mainly for political reasons, the chapter also argues that the adoption of such a measure is considered as rather unlikely.
As policy makers acknowledge the high degree of supply chain vulnerability and the impact of maritime emissions on coastal population health, there has been a consistent effort to strengthen maritime security and environmental regulations. In recent years, overdependence on deeper and wider multinational supply and production chains and lean-optimization has led to tightly integrated systems with little “slack” and high sensitivity to disruptions.
This study considers the impact of Emission Control Areas and establishes a link between environmental and network resilience performance for maritime supply chains using operational cost and SOx emissions cost metrics. The proposed methodological framework analyzes various abatement options, disruption intensities, fuel pricing instances and regulatory strategies. The methodology utilizes a minimum cost flow assignment and an arc velocity optimization model for vessel speed to establish the payoff for various network states. Additionally, an attacker defender game is set up to identify optimal regulatory strategies under various disruption scenarios. The results are complemented by a sensitivity analysis on SOx emissions pricing, to better equip policy makers to manage environmental and resilience legislation. The methodology and findings provide a comprehensive analytic approach to optimize maritime supply chain performance beyond minimisation of operational costs, to also minimize exposure to costly supply chain disruptions.
In an effort to reduce the environmental impacts of maritime transportation, the International Maritime Organization (IMO) designated special Sulphur Emission Control Areas (SECAs) where ships are required to use low-sulphur fuel. In January 2015, the sulphur limit within SECAs was lowered to 0.1%, which can only be achieved if vessels are using pricier ultra-low sulphur fuel, or invest in abatement technologies. The increased operating costs borne by Ro-Ro operators in SECAs due to the stricter limits can result in the shutting down of some routes and a redistribution of cargo flows with land-based alternatives. The exact repercussions of the new sulphur limits are difficult to identify in the wake of significant recent reductions of the fuel prices for both low-sulphur and heavy fuel oil. This paper presents a modal split model that estimates modal shifts vis-a-vis competing maritime and land-based modes available to shippers. This allows examining the implications of the recent low prices to modal choice, and the influence a potential increase in fuel prices may have. The model is applied to seven routes affected by the regulation based on data from a leading European Ro-Ro operator. Sensitivity analyses on market share data, cargo values, freight rates, and haulers rates are conducted. Emissions inventories are constructed to assess the environmental efficacy of the SECA regulation. The novelty of the proposed model lies in the examination of the ex-post implications of shutting down a service and the redistribution of transport. Recommendations to mitigate and reverse the negative side-effects of such environmental legislation are proposed.
This chapter examines the development of the law of the sea at the time of the League of Nations with specific focus on the entitlement to the oceans and the use of the oceans. This chapter first addresses the entitlement to and jurisdiction over marine spaces by examining the issue of the territorial sea, the contiguous zone, bays and islands. The chapter then examines the issue of the use of the oceans, focusing on the regulation of fishing and navigational rights in straits. Finally, the chapter will conclude that the era of the League of Nations can be thought to be one in which the traditional paradigm of the law of the sea was being formulated. However, the paradigm was qualified by the absence of an agreement with regard to the breadth of the territorial sea and rules regarding the delimitation of the territorial sea. In this sense, the paradigm in that period remained incomplete. Furthermore, the time was not ripe to establish a global legal framework for the conservation of marine living resources. Overall the law of the sea at the time was characterised by the reconciliation of competing interests of individual states.
A major part of the world fleet of more than 47,000 merchant ships operates under conditions that hamper energy efficiency and efforts to cut CO2 emissions. Valid and reliable data sets on ships' energy consumption are often missing in shipping markets and within shipping organizations, leading to the non-implementation of cost-effective energy efficiency measures. Policy makers are aiming to remedy this, e.g., through the EU Monitoring, Verification and Reporting scheme. In this paper, current practices for energy consumption monitoring in ship operations are explored based on interviews with 55 professionals in 34 shipping organizations in Denmark. Best practices, which require several years to implement, are identified, as are common challenges in implementing such practices—related to data collection, incentives for data misreporting, data analysis problems, as well as feedback and communication problems between ship and shore. This study shows how the logic of good energy consumption monitoring practices conflict with common business practices in shipping companies – e.g., through short-term vessel charters and temporary ship organizations – which in turn can explain the slow adoption of energy efficiency measures in the industry. This study demonstrates a role for policy makers or other third parties in mandating or standardizing good energy consumption monitoring practices beyond the present requirements.
