Abstract
Shipbuilding is an energy-intensive industry and has negative environmental impacts. Given the contribution of the production phase to ships' air emissions throughout their life cycle, there is no international regulation to monitor, control or reduce air emissions during this phase. However, it may be covered by State’s Nationally Determined Contributions (NDC) under the Paris Agreement. Achieving a zero-emission shipping industry requires a broader, holistic, systematic and "cradle to grave" approach that takes into account the life cycle of the ship, from production to scrapping.
The aim of the study is to develop to a holistic and systematic approach to reducing air emissions and improving energy efficiency in the construction phase of the ship life cycle. By taking into account holistic and transdisciplinary approaches and combining socio-technical principles and multi-criteria decisionmaking (MCDM) methods, new approaches are proposed for a comprehensive evaluation of measures and tools to reduce air emissions and improve energy efficiency in shipyards. Case studies of shipyards of different sizes, geographical locations and with different portfolios are used to demonstrate these approaches.
The main contributions of the thesis are
• Classifying shipyards into clean and green shipyards on the basis of environmental pollution;
• Replacing one-dimensional thinking with holistic, systematic and transdisciplinary thinking to break down the silos between different disciplines in the shipbuilding industry;
• Identifying the measures and tools that can be used to reduce air emissions and improve energy efficiency in shipyards and classify them into five main areas;
• Designing and developing a holistic, systematic and transdisciplinary energy management framework to support decision makers in shipyards in the uncertain atmosphere in order to make rational and optimal decisions to improve energy efficiency and reduce air emissions and promote the concept of sustainability in their processes;
• Implementing the proposed energy management framework in five different shipyards and evaluating the sustainability of shipyards with reference to four sustainability theories, i.e. corporate social responsibility, corporate sustainability, stakeholder theory and green economy;
• Improving the sustainability of shipyard-cities through the implementation of the framework, which offers a comprehensive approach to address environmental, social, and economic challenges;
• Promoting shipyards as an energy hub in the maritime industry by providing renewable energy and alternative fuels;
• Creating hypothesis regarding sustainability performance of shipyards with respect to their sizes, geographical locations and portfolios;
• Designing, developing and implementing a transdisciplinary framework to identify barriers to energy efficiency improvement and implement it in one shipyard in a case study.
