Move/Offset Curves Perpendicularly

Still beginner level, but how could I move/offset these lines perpendicularly? Still wrapping my head around vectors so I hope for your patience guys, thanks!

post the script

Thank you for responding! I just came across the component OffsetCurveFromSurface in the Pufferfish plugin, and it achieved what i exactly needed. Cheers

Mark as solved.
