Abstract： A company plans to convert a 5000t launching barge， originally designed for Inland River Class B navigation areas， into an offshore transport barge to better align with corporate development and current market demands.This paper analyzes the feasibility ofthe conversion scheme and focuses on the challnges in structural redesign under the requirements of the China Clasification Society （CCS），including longitudinal strength calculation beyond standard specifications，direct wave load calculation，structural compliance assessment，and global fnite element analysis.The proposed conversion scheme ofers simplified construction and provides reference for similar vessel modifications.

Key words： conversion design; semi-submersible barge; offshore transport barge
