Offshore　oil　and　gas　development　requires　increased　corrosion　resistance　due　to　exposure　to　harsh　and　corrosive　environments.　The　use　of　lined　pipes　with　both　significant　mechanical　and　corrosion-resistant　properties　has　become　increasingly　widespread　in　the　offshore　oil　and　gas　industry.　The　potential　pipeline　torsion　trend　during　the　installation　stage　may　affect　the　structural　integrity　of　the　adopted　lined　pipe　and　has　become　threats　to　offshore　construction.　This　study　conducted　torsion　tests　on　lined　pipes　and　captured　the　structural　behaviors.　Finite　element　(FE)　models　were　developed　to　investigate　the　failure　modes,　the　developments　of　the　liner　wrinkle　and　the　interaction　stress　between　the　outer　and　liner　pipes.　The　mechanism　of　how　the　interaction　behaviors　developed　and　the　improvement　of　composite　action　between　the　constitutive　parts　had　been　quantitively　discussed.　Additionally,　a　series　of　parametric　studies　were　conducted　to　study　the　effects　of　the　outer　pipe　strength,　the　outer　pipe　thickness　and　the　length　of　the　lined　pipe.　Finally,　the　improved　method　for　the　design　torque,　considering　the　contribution　from　the　liner　pipe,　has　been　proposed.　This　study　can　provide　valuable　references　for　the　design　and　installation　of　lined　pipes　under　torsion.　©　2023　Elsevier　Ltd
