Feasibility of Investment in Renewable Energy Systems for Shipyards

Abstract

SummaryShipbuilding industry is generally considered as one of the key global industries. It consumes a significant amount of energy and leaves a strong footprint on the environment. It is therefore required to try to increase renewable energy sources in the shipbuilding industry in accordance with the adopted international legislation. This will improve energy efficiency of shipyards and reduce their impact on the environment. The present preliminary study contributes to those goals as application of sustainable renewable energy systems in ship production industry is considered. The analysis is performed for solar panels, tidal and wind turbines with respect to their technology readiness and investment costs, as well as for the total energy consumption. While in the present work the research hypothesis is studied on example of a typical Croatian shipyard, the general findings are expected to be widely applicable to all shipyards. The solar panels are considered as the most suitable renewable technology, while the investment return period for introducing solar panels to satisfy the entire electrical energy demand in this particular case is approximately seven years. The impact of introducing this green shipbuilding approach is considered beneficial in comparison with current conventional electrical energy production based on conventional energy sources.

Sustainability Concept in Turkish Shipyards

“…Technological innovations should be cost effective for an energy efficiency of main engine and a sustainable improvement (Xie et al [20]). Solar panels are considered as the most suitable and sustainable technology (Hadžić et al [21]). Gaining wood durability, adopting alternative native wood or wood cored sandwich composites may be a solution to enhance the artisanal boatyard's sustainability (Walter et al [22]).…”

Energy‐related clean and green framework for shipbuilding community towards zero‐emissions: A strategic analysis from concept to case study

“…In addition, the development of smart shipyards using data envelopment analysis has been shown by Woo et al 46 and the implementation of Industry 4.0 at shipyards using fuzzy AHP-TOPSIS hybrid method has been explained by Cil et al 47 The utilization of different types of renewable energy in shipyards has been investigated in various studies. Hadži c et al 48 identified the feasibility of investments in renewable energy systems for shipyards and the use of a photovoltaic power plant for a shipyard, and the potential of wave power parks for shipyards in Portugal was explored by Miglietta 49 and Neumann et al, 50 respectively. At the same time, the implementation of floating offshore wind platforms in shipyards was addressed by Castro-Santos et al 51,52 Energy efficiency decisions and the selection of main engines in a sustainable shipyard supply chain were addressed by Xie et al 53 and Krishnan et al 54 examined optimal cargo handling in a shipyard.…”

“…The human element (such as Training, 126 Governance and Corporate Social Responsibility, 127 Education, 128 Capacity building, 129 Awareness Raising, 130 Research and Development (R&D) 131 ) was chosen as one of the disciplines in the EnMF because within the complex socio-technical system and shipyard sectors plays a crucial role and is continually being transformed and redefined by technological advancement. 132 Moreover, technology and innovation (including Digitalization (fourth Industrial revolution), 133,134 Micro Grid, 135 Renewable Energy, 48 Electrification (Battery, Fuel cell etc. ), 136 Alternative clean fossil fuel (Natural gas etc.…”

“…55 Moreover, policy and regulation discipline including Environmental regulations (International, Regional, National, and Local), 146 Life Cycle orientation, 147 Green Products, 148 Innovation, sustainability, and competitiveness, 149 Energy Management System (ISO 50001), 150 Environment Management System (ISO 14001), 151 Cyber security, 152 Circular Economy, 153 and Voluntarily agreement 154 is one of the most important factors to assist the shipping industry in achieving its ambitious goal for a substantial and swift reduction for carbon emissions reduction and the sociotechnical transition within the sector. 155 Finally, economic factors and analysis including Financial Source, 156 Cost of energy, 157 Levelized cost of energy, 52 Lifecycle cost, 48 Societal cost, 158 Economic competitiveness, 31 Cost saving, 157 Incentive 159 due to its important role in decision making and competitiveness within the shipyard and the maritime cluster 160 were chosen as the fifth discipline in the EnMF.…”
