Looking for some FEU data, please!

My son is a U.S. Merchant Marine Engineer and quite busy at present. I am attempting to take up a bit of slack for him and appreciate any contacts/insight/suggestions to help me get the answers to these questions for him.

He is preparing a business plan proposal to convert one-trip FEU’s into low-cost housing and has received some venture capital “interest”.

As it pertains to FEU’s (or TEU’s if that is the only info available):

  1. Worldwide number of containers fabricated each calendar year?

  2. Worldwide number of containers removed from circulation each calendar year?

  3. Worldwide number of “one-trip” containers used per calendar year?

  4. What is the rough cost to manufacture a FEU?

  5. What is the average number of loaded containers offloaded/delivered per port call?

Thanks in advance for your time; any help with this will be much appreciated!!

Best Regards,
L. C. Riales
