I think its actually Sansevieria cylindrica, and as such, it needs higher light levels than many of the other varieties. Grown in bright daylight, it will be more erect and is less likely to collapse the way yours has done, though some stems may still splay to an extent. It also looks as if it needs to be set just slightly lower in its pot, so that the soil is supporting the base of the plant better.
If you can find a spot for it where it will get bright daylight, even with some sun, then I'd cut out the more splayed out stems, leaving the more upright ones. As the pot its currently in is almost full to the brim, I suggest you find a slightly taller pot, but not bigger otherwise, and repot, increasing by not more than quarter to half an inch the depth at which its planted, or just add horticultural grit to the top of the pot to provide a bit more support, again no deeper than quarter of an inch, and see what happens. With regard to the height of the pot, its better to always have one that's tall enough to leave a clear half an inch at the top with no soil or plant roots, to facilitate watering (stops it running over the edge before penetrating the soil). With better light conditions, it should produce more erect growth. More info about this plant generally in the link below - growing as a houseplant, scroll down the page
