In marine engineering,risers carry the mission of connecting floating offshore equipment and underwater production systems,and are a key channel for the development and utilization of deepwater oil and gas fields.However,due to the need to withstand high-strength working pressure and the difficulty of welding construction,the riser has become the weakest link in offshore oil and gas production systems.Given the high standards and strict requirements of riser welding construction,the construction process generally only allows for one repair.Based on this,this article takes the commonly used X65 steel riser on domestic offshore platforms as the research object,summarizes the operational points and technical difficulties of riser welding repair technology,aiming to provide theoretical guidance and practical significance for the welding repair of riser on offshore platforms in China.
