Hello Josail,

Thanks for the response.

I do believe that having this data could be beneficial to others and to prevent accidental damage to the seabeds. So having this data would be good.

The problem I still see however is that the CC BY 4.0 international license has some compatibility issues with the ODbL license OSM uses. 
See: https://blog.openstreetmap.org/2017/03/17/use-of-cc-by-data/
That blog post also contains a link to a waiver document that can be used to ask the authors for express permission. 

A further problem I see is that imports have very specific guidelines that must be followed.
See this page: https://wiki.openstreetmap.org/wiki/Import/Guidelines
This is to allow other users to chime in with regards to how they feel about this import, to asses the quality, how this import should be done and other things like that. I could not find any discussion about this import in the community forums nor in the import catalogue wiki page. 

Sincerely,
Taya
