Abstract: An expansion joint is an important device in offshore oil facilities(deepwater drilling platform)and is pro-duced by foreign professional manufacturers. Due to wear,aging or other reasons,failure of expansion joints will affect the safe operation of the facilities. When one fault occurs,usually a whole set of equipment needs to be pur-chased from the manufacturer. In 2012,malfunction of expansion joints was found in an offshore oilfield in South China Sea. As the overhaul needed to be timesaving,but the purchase period was long and lacked economical effi-ciency,the repairing of expansion joints were performed domestically,which satisfied the normal operation of the oilfield. The repair process adopted mature techniques(not recommended or guiding techniques from the manufac-turer). After the repairing,the equipment is now under normal service conditions. This paper described the repairing process and matters worthy attention.
