This guide will let you know where to find Seamoth Fragments in Subnautica.
Starting from the coral tube sticking up out of the water, you can head northwest east, or you can head southwest until you reach the Grassy Plateau’s biome.
It is recommended to have a rebreather, a high capacity 02 tank, a sea glide, and you will also need a scanner.
There aren’t any major threats in the area that you need to worry about while searching for sea moth fragments.
The coordinates for the location are (-510, -91, -45).
Once you reach either one of the grassy plateau’s, you have to search around on the seafloor of the biome for sea moth fragments, and they can be a bit scattered out. You might have to do a bit of searching until you find enough fragments to get the blueprint.
If you give up on looking for fragments in the grassy plateau’s or you can’t find any, then the other place you can go is inside of the aurora in the sea moth bay in which you should be able to find fragments there if you weren’t able to in the grassy plateau’s.
