To go with these shipbuilding related posts, I found this interesting report from Boston Consulting group. Specifically, this image below:
The above statistics are very interesting and not what I would have expected. The US doesn't have drydock disadvantage (in terms of drydocks) against Korea or Japan, nor does it have a labour force or revenue disadvantage. Yet it has virtually has no commercial shipbuilding and its Naval output is struggling to expand.
IMO these are largely ambiguous figures.
1. Revenue - US ship building revenues would likely be from expensive aircraft carriers, nuclear power submarines etc while figures for Japan China and Korea are likely publicly available figures for commercial ships. Meaning less ships and small tonnages built in USA compare to others despite the cost per ship, example more than US$12 billion for only one 100,000 tons aircraft carrier, there is huge disparity between revenue earned and number/tonnages of ships built.
2. Workforce - what kind of skill levels and how much robotics are employed instead of human workers?
3. Dry docks - sizes, different capabilities and areas must be clearly stated.
4. Deepwater ports - more relevant to import/export than ship building capabilities.
5. Deepwater coastlines - irrelevant.
6. Industrial waterfront - SIze could be useful but shipbuilding infrastructure on the property is more relevant.
