[Inquiry] Top 20 shipping companies

[freeloadx]

I am currently embarking on my school project regarding the shipping domain.

I would like to find out which are the top 20 shipping companies that are accountable for majority of the transits through the Gulf of Aden.

Your help will be greatly appreciated. Any advice on how to go about doing the research is also welcomed. Thank You.
