Technical seaworthiness in maritime operations is resource-intensive, demanding operational efficiency through
waste reduction. This study investigates waste types in this sector, which faces unique challenges beyond
conventional manufacturing. Using a qualitative, single case study design within an interpretivist paradigm, the
research explored the nuanced interactions of waste in Sri Lankan maritime technical seaworthiness processes.
Eleven in-depth interviews and five focus group discussions were used to collect rich and context specific data
form the participants' through subjective experiences. Eight key waste categories emerged: unnecessary data
processing, capacity constraints, lack of standardisation, poor governance, inadequate human resources,
inconsistent culture, supply chain inefficiencies, and excessive bureaucracy. Contributing factors included poor
data accessibility, centralisation issues, resource scarcity, regulatory adherence, and insufficient training.
Categorisation of these wastes as value-added, non-value-added and necessary non-value-added activities further
clarified their impact. This study offers a framework for minimising non-value-added activities and optimising
others, enhancing operational performance. It provides critical insights into operational and process inefficiencies
within the Sri Lankan maritime context, guiding strategies for waste reduction and improved efficiency.
