This paper delves into end-user perspectives on the adoption of Remote Inspection Techniques (RIT) that can serve the needs of the maritime transport industry (as examined under the European Union’s (EU) BUGWRIGHT2 project), highlighting their potential to meet classification and statutory survey requirements while adhering to regulatory standards...

Emerging technologies and technologies with emerging applications are starkcatalysts of transformation in the maritime industry. As the industryprogressively shifts to remote inspection techniques (RIT), there is a growingneed to identify and assess the potential hazards that exist within thebreadth and scope of vessel surveys and inspections. Such...

Circular economy business models are key enablers of the circular economy. However, they must also be economically viable to materialize in reality, since profitability is a major business driver. Assessment of the economic potential of circular economy business model is subjected to significant uncertainties and to a range of risks, due to their n...

The growing use of composites in various industries such as aerospace, automotive and wind turbine has increased environmental concerns regarding their waste disposal methods. Deploying circular economy practices to reuse composites could play a crucial role in the future. In this regard, this chapter addresses the development and implementation of...

Carbon fibre reinforced polymer is a widely used material in engineering applications and is expected to be extensively used in the transportation sector due to its light-weight properties. It is a high value, energy intensive material, which is mostly landfilled at its End-of-life, however, it could potentially be recycled and replace virgin mater...

Recent regulations are targeting the carbon footprint of ships and the International Maritime Organisation (IMO) has set a target to reduce the GHG emissions by 50% until 2050, compared to the 2008 levels. Therefore, attention has been placed on the variety of available fuels and technologies that can be potential pathways for decarbonisation and s...

The transportation sector is a great contributor of global carbon emissions, thus technical, regulatory, and behavioural efforts are being made to move towards more sustainable mobility, reducing the sector's environmental impact. Among the proposed solutions, car sharing is an appealing alternative for both environmental and societal reasons. Howe...

Batteries and hydrogen constitute two of the most promising solutions for decarbonising international shipping. This paper presents the comparison between a battery and a proton-exchange membrane hydrogen fuel cell version of a high-speed catamaran ferry with a main focus on safety. The systems required for each version are properly sized and fitte...

Recently, the shipping industry has been under increasing pressure to improve its environmental impact with a target of a 50% reduction in greenhouse gas emissions by 2050, compared to the 2008 levels. For this reason, great attention has been placed on alternative zero-carbon fuels, specifically ammonia, which is considered a promising solution fo...

The shipping sector has been under great pressure since the last decade to improve its environmental footprint, more so recently with the International Maritime Organisation target for a 50% reduction in greenhouse gas emissions by 2050, benchmarked to 2008 levels. These challenging goals have increased the interest towards alternative fuels and sh...

The shipping industry has been under pressure to improve its environmental impact leading to the accelerated development of alternative zero-carbon fuels. Ammonia-powered Solid Oxide Fuel Cell systems are proposed as a prominent solution that can tackle these environmental challenges. However, there are safety and reliability concerns that need to...

In April 2018, the International Maritime Organisation adopted an ambitious plan to contribute to the global efforts to reduce the Greenhouse Gas emissions, as set by the Paris Agreement, by targeting a 50% reduction in shipping's Green House Gas emissions by 2050, benchmarked to 2008 levels. To meet these challenging goals, the maritime industry m...

Wind energy installations are increasing rapidly and so is their end-of-life waste. Wind turbine blades consist primarily of glass fibers and are usually landfilled. Given the significant amounts of blade waste expected in the future, circular economy pathways need to be identified for this waste stream. This study investigates the feasibility of t...

2018, ο Διεθνής Οργανισμός Ναυτιλίας (ΙΜΟ) υιοθέτησε ένα φιλόδοξο σχέδιο για να συμβάλει στις παγκόσμιες προσπάθειες για τη μείωση των αερίων του θερμοκηπίου (GHG), σύμφωνα με την Συμφωνία του Παρισιού. Πιο συγκεκριμένα, ο ΙΜΟ έβαλε στόχο για τη μείωση των εκπομπών αερίων του θερμοκηπίου της ναυτιλίας κατά 50% έως το 2050, σε σύγκριση με τα επίπεδα...

The stringent regulatory framework for the emissions and safety from shipping operations as well as the market pressure to reduce the operational costs has led the cruise ship industry to pursue and investigate alternative solutions for both the new-built and the existing ships by using multi-objective optimisation methods. This study aims at inves...

Wind power is a key renewable electricity source for Europe that is estimated to further develop significantly by 2050. However, the first generation of wind turbines is reaching their End of Life and the disposal of their blades is becoming a crucial waste management problem. Wind turbine blades consist primarily of reinforced composites and curre...

The Energy Efficiency Design Index (EEDI) was introduced as a regulatory tool employed at the ship design phase to reduce the carbon dioxide (CO2) emissions and increase the vessel’s operational efficiency. Although it stimulated the greening of the shipping operations, its effectiveness is considerably criticised from various shipping industry sta...

The stringent regulatory framework for both emissions and safety as well as the market pressure to reduce the operational costs led the cruise ship industry to pursue alternative solutions. In this respect, multi-objective optimisation methods can be employed for decision-making for identifying optimal solutions with improved efficiency, lower envi...

The shipping industry has been facing increasing challenges due to the stringent regulations for anthropogenic emissions limits, the new targets for carbon emissions reduction and the potential carbon pricing introduction. These have led to an upsurge of activities towards improving the environmental footprint of cruise ships. This study investigat...

The shipping industry has been facing great pressure to become more sustainable, emanating from the increasingly stringent environmental regulations, fuel prices volatility and societal needs. As a result, a variety of technologies have been developed aiming to improve the environmental and economic performance of the modern ship energy systems, ho...
