This dissertation explores the potential of using marine algae, both microalgae and macroalgae, as efficient carbon capture agents, capable of absorbing CO₂ emissions up to 50 times faster than terrestrial plants. In addition, the study examines various carbon capture technologies, such as pre-combustion and post-combustion systems, and evaluates how algae-based systems can be optimized for onboard and onshore applications. Moreover, cultivation methods, including closed photobioreactors and open systems, are analyzed for their efficiency, scalability, and feasibility in maritime environments. Furthermore, this work highlights the potential for integrating algae cultivation with the Green Shipping Corridors initiative, offering sustainable pathways for vessel decarbonization through biofuel production and carbon sequestration. Finally yet importantly, the findings suggest that algae-based carbon capture can significantly contribute to reducing vessel emissions, promoting circular economy practices, and aligning with global climate targets. Further research into the economic and technical aspects of this integration is recommended to fully realize its potential.

Not only China is the second largest economy but is also a major shipping player, including shipbuilding and ship-financing services. The economic decoupling adds more uncertainty to an already shaken global environment of the last decade, shaped by several disruptions, such as Covid-19 pandemic, BREXIT, the Russo-Ukrainian War, along with the Trump Tariffs in 2018, create uncertainties that affect the shipping industry, representing more than 90% of global trade. This dissertation aims to provide answers by studying the disruption of US and China trade-war on Seaborne Trade. In the following dissertation it is proved that the interaction between the two economies and seaborne trade is decreased after 2018.

Authors: Ioannidi, Polyxeni-Eleni Abstract: This thesis is focused on the use of Electronic Bill(s) of Lading in the maritime industry. The idea of a paperless trade is not new; it goes back to the 1980s. Many projects tried to provide solutions for the electronic commerce but how did the shipping market react? Are we or will be ready eventually to leave behind the cost, risk and bureaucracy of the traditional trade or not? Has the legal framework and the technology changed enough to allow the shipping market to adopt for good the electronic Bills of Lading? The significance of the Bills of Lading and the developments of the dematerialization of the traditional, paper Bills of Lading towards the era of the Electronic commerce is displayed in the introduction. The problems of the paper Bills of Lading and the requirements for the validity and proper performance of the Electronic Bills of Lading will be analyzed. A retrospection to the first steps for the use of the Electronic Bills of Lading up to the latest developments in this scheme will be provided further below. The four key factors- Legal framework, Operational nature, Network of users and technology- in the use of Electronic Bills of Lading (EBL) will be discussed in detail in order to ascertain all those issues that keep alive the use of traditional, paper Bills of Lading instead if the Electronic type. At the second part, statistical data from the shipping industry will be exposed. The method is based on a survey, which was distributed electronically in a worldwide sample of key players in the shipping market, which make use of Bills of Lading. Interviews, opinions and comments from Ship-owners and traders will be also included for better understanding of the benefits and the drawbacks of Electronic Bills of Lading. Findings from this research will be reported in last part of this study. Critical review, estimations and future perspectives in the use of Electronic Bills of Lading will follow. Finally, brief summary of the issues and the key findings will be included in the conclusion, trying to present an answer to the question whether the Electronic Bills of Lading are/or will be a practical tool for the shipping industry or not.

The main principles of the marine insurance legislation stipulate that the vessel serves the role of the collateral under the insurance contracts and can be used for the extensive protection over financial institutions against damage. Today the marine industry is rich for the numerous companies owning from one to several ships. In this regard, it is clear that some companies lack significant resources in case of damage of the ship. Thus, the majority of the business units in the marine sphere rely on the mortgages insurances so as to avoid unnecessary payments for the causation of damage to the vessel. With the end of the financial crisis, the power of the ship-owners’ insurance has been increased. There is a variety of insurances that can be signed between the shipping companies and lending institutions for minimizing credit risks. Meanwhile, the financial institutions today are much more cautious in the conclusion of the insurance contracts with the ship-owners as they pose certain risk for them. Hence, this thesis explores the nature of the insurance contracts and mortgages’ insurances existing under the current marine English legislation of the global scope. The evaluation of the insurance protection evidences that the financial institutions are not given the adequate protection. In this regard, the recommendations for the banking institutions are considered through the thesis in order to have a smooth cover for both parties in the agreement.
