Abstract： The flap rudder connecting sleeve assembly for a new large Small Waterplane Area Twin Hull （SWATH） vessel is supplied in its final state，requiring no post-instalation machining on the berth.This imposes higher demands on precision control during instalation.This paper detailscontrol measures for the installtion process of the connecting sleeve. Appropriate welding techniques are adopted to mitigate thermal deformation， and real-time monitoring of deviations between the inner bore center and the theoretical rudder system center is conducted during welding.This enables timely adjustments to the welding sequence，ensuring installation accuracy. Through rigorous analysis and practical application， these measures provide valuable insights for the construction of similar vessels in the future.

Key words： SWATH; flap rudder; connecting sleeve; process control
