- Global competition: Glasgow's shipyards faced increasing competition from shipyards in other countries, particularly in Asia, where labor costs were lower.
- Technological change: The introduction of new shipbuilding technologies, such as containerization, reduced the demand for traditional shipbuilding skills.
- Economic restructuring: The decline of heavy industry in Glasgow and the UK more broadly led to a loss of demand for ships built in the city.
- Government policies: Government policies, such as the privatization of the UK shipbuilding industry in the 1980s and 1990s, also contributed to the decline of shipbuilding in Glasgow.
As a result of these factors, the number of shipyards in Glasgow has declined from over 100 in the early 20th century to just a handful today. However, the city's shipbuilding industry is still active, and there are plans to build new shipyards in the future.
