S.C. Code § 29-9-50
Such lien may be enforced by petition to the court of common pleas for the county in which the vessel was at the time the debt was contracted or in which she is at the time of instituting proceedings. The petition may be entered in court or filed in the clerk's office in vacation or may be served with the summons, with an order of attachment, and returned and entered as other civil actions and the subsequent proceedings for enforcing the lien shall, except as herein otherwise provided, be as prescribed for enforcing liens on buildings and lands, so far as applicable. At the time of entering or filing the petition a process of attachment against such ship or vessel, her tackle, apparel and furniture shall issue and continue in force or may be dissolved like attachments in civil cases, but such dissolution shall not dissolve the lien.
