The requirement from IMO regarding an environment-friendly approach has prompted ship owners and shipbuilders to make sure their vessels complying the regulations. Green shipyards, incorporating best practices and technology, can reduce th polution generated during vessel construction. This paper investigates the current trends of green shipbuilding and proposes potential practices of green shipyard. A systematic review was conducted using publication databases such as Scopus, Science Direct, and Taylor & Francis from 2010 to 2022. It can be concluded that most of the studies have been discussing the Industry 4.0 (I4.0) technologies to be implemented in the shipyard where 16 potential practices and technology-based in the green shipyard were figured out. This study also found that automation is the most discussed topic in I4.0 technologies followed by an alternative fuel (LNG/LPG fuelled engine) and 3D printing and design. Furthermore, the study on green shipbuilding attracted the attention of China and Spain as these countries have published most papers. This study will help Malaysian shipbuilders and stakeholders to have a better view regarding the green shipyard concept and related practices and technology. [ABSTRACT FROM AUTHOR]
