Sustainability and Environmental Considerations in Marine Welding

This chapter addresses the growing imperative of sustainability in marine welding operations, aligning with global initiatives such as the International Maritime Organization’s (IMO) decarbonization goals and the European Green Deal. It examines the environmental impacts of conventional welding, including energy consumption, emissions, and waste generation, before introducing strategies to reduce the carbon footprint of shipyard operations. Topics include energy-efficient welding processes, renewable energy integration, low-emission consumables, and life cycle assessment (LCA) for carbon accounting. The text also highlights recycling and eco-friendly practices, such as reusing scrap metals, developing low-volatile organic compound (VOC) fluxes, and adopting solid-state welding techniques like friction stir welding (FSW) and wire arc additive manufacturing (WAAM). Waste management, fume control, and eco-safe personal protective equipment are also discussed in the context of occupational safety. By incorporating sustainability metrics into welding engineering, this chapter emphasizes the shift toward green manufacturing, circular economy principles, and environmentally responsible shipbuilding, ensuring that the marine industry evolves in harmony with ecological and regulatory demands.
