“…Additionally, the authors underlined the potential for the combined implementation of these initiatives, suggesting that these could result in GHG emissions reductions of more than 75% by 2050. However, only a limited number of case studies show how emissions reductions from the implementation of combined initiatives could be achieved in practice (Styhre et al 2017;Searcy 2017;Baldi et al 2015;Johnson et al 2013).…”

The aim of this paper is to analyse shipping firms’ reactions to environmental challenges and identify how significant reductions in energy consumption and air emissions can come about by implementing a variety of voluntary initiatives. The paper focuses on the various sustainability initiatives implemented by the Swedish short sea shipping operator, Stena Line, either on a purely voluntary basis as part of their corporate social responsibility (CSR) strategy or as their chosen route for compliance with regulations. A conceptual model is developed based on stakeholder theory, the theory of planned behaviour and resource dependence theory to understand the main drivers of the firm’s adoption of sustainability initiatives and the factors affecting the integration of CSR in maritime companies. According to our findings, the company operates within a strongly enforced regulatory environmental framework and needs to exceed this framework to differentiate its service and strengthen its relationships with its customers by addressing their social and environmental concerns. As the firm’s competitive strategy focuses on service differentiation, a large pool of complementary resources is available for CSR and the implementation of sustainability practices. The results of this paper bring new insights to the potential of local private voluntary initiatives for the reduction of maritime air emissions. These include the provision of onshore power supply, the conversion of vessels to use methanol, ferry electrification, the construction of larger RoPax vessels and the implementation of an energy-saving program that focuses on crew involvement and continuous training. The environmental outcomes derived from a combination of local operational and technical energy efficiency measures are found to be significant and can contribute to the efforts for the achievement of sustainable maritime transport undertaken by international and regional organisations. The main barriers for the adoption of voluntary sustainability initiatives in the maritime sector are economic and technological. To encourage the wider adoption of these initiatives, the provision of economic incentives at national or regional level is crucial, as such initiatives usually imply high initial installation costs that should be somehow compensated for both vessels and terminals.

“…When induced wind current attacks a rotating cylinder, it retards the air on one direction and accelerates it on the opposite direction. High- and low-pressure regions will be formed around the rotating cylinder (Badalamenti and Prince 2008 ; Searcy 2017 ; Seifert 2012 ; Zdravkovich 1997 ). As a result of this pressure difference, lift and drag forces will be developed in the perpendicular and the parallel directions of the wind flow, respectively, as shown in Fig.…”

“…Recently, two 30-m-tall rotor sails have been installed on a Maersk Tankers vessel (Norsepower 2015 ). Arief et al ( 2018 ), Lele and Rao ( 2017 ), Searcy ( 2017 ), Seifert ( 2012 ), Talluri et al ( 2018 ), and Traut et al ( 2014 ) analyzed and evaluated the potential for implementing Flettner rotor systems for different ship types. As a step toward studying the applicability of the use of Flettner rotors in marine application, the present paper aims to analyze the Flettner rotor performance and to study the effect of different parameters on the turbine’s net output power.…”

Shipping faces challenges of reducing the dependence on fossil fuels to align with the international regulations of ship emissions reduction. The maritime industry is in urgent need of searching about alternative energy sources for ships. This paper highlights the applicability of harnessing wind power for ships. Flettner rotors as a clean propulsion technology for commercial ships are introduced. As a case study, one of the bulk carrier ships operating between Damietta port in Egypt and Dunkirk port in France has been investigated. The results showed the high influence of the interaction between ship course and wind speed and direction on the net output power of Flettner rotors. The average net output power for each rotor will be 384 kW/h. Economically, the results reveal that the use of Flettner rotors will contribute to considerable savings, up to 22.28% of the annual ship’s fuel consumption. The pay-back period of the proposed concept will be 6 years with a considerable value of levelized cost of energy. Environmentally, NO x and CO 2 emissions will be reduced by 270.4 and 9272 ton/year with cost-effectiveness of $1912 and $55.8/ton, respectively, at annual interest rate of 10%.

“…To approximate investment amounts across vessel types, wind-assisted propulsion (WASP) upgrades were used as an indicative technology benchmark. The propulsive potential of wind energy for new-builds and retrofits has been frequently reviewed [71][72][73][74][75][76][77]. A respective overview of the current technology status as well as future potentials of wind propulsion solutions was submitted to the IMO for the 75th session of the MEPC by Comoros [21].…”

Decarbonizing maritime transport is among the top priorities of regulators and continuously attracts significant research attention. However, the cost of renewing and greening the fleet has not been explored in detail. To address this gap, the paper provided a bottom-to-top estimation of the financial need associated with decarbonizing the global shipping fleet for the next 5 years, i.e., until 2026. By developing a model focusing on the main asset classes, the paper approximated the expenditure implied in the short-term fleet renewal (newbuilding and vessel demolition) as well as the expenditure linked to retrofitting the existing fleet. The results indicated an aggregate financial need of USD 317bn until 2026. Thereof, USD 235bn are associated with building new ships, while USD 114bn are allocated to retrofitting. Furthermore, proceeds of USD 33bn can be generated via demolition sales of old tonnage, reducing the total financial burden. The results entail important policy implications, as they document the monetary impact on investors, lenders, and shipping companies regarding distinct segments of the fleet. Considering the declining overall supply of capital towards shipping, the given results provide a transparent account of the absolute financial implications of decarbonization policies.
