  The Electron-Ion Collider (EIC) plans to utilize the local crabbing crossing
scheme. This paper explores the feasibility of adopting a single crab cavity
with adjusted voltage, inspired by the successful global crabbing scheme in
KEKB, to restore effective head-on collisions. Using weak-strong simulations,
the study assesses the potential of this global crabbing scheme for the EIC
while emphasizing the need for adiabatic cavity ramping to prevent luminosity
loss. Additionally, the research outlines potential risks associated with beam
dynamics in implementing this scheme.
