Other salvage projects from the period Titanic sank (1912/1915) than the magnet one?

[Aurélien WOLFF]

Hello, I know there was this idea of using magnets tied to a lot of ships to raise the wreck , but I can't find anything on other project from the period. If other things were proposed to salvage the ship in the aftermath of the sinking, can someone describe them here and if possible post pictures from the time showing the proposed salvage method?
Thanks for your answers!
