This paper presents work carried out to develop and qualify a new type of lightweight composite hoop wound pipe for drilling riser applications. These tubes are made of a steel pipe reinforced by a prestressed winding of unidirectional thermoplastic-aramid composite. The winding parameters are carefully calculated to optimise the distribution of tension/compression stresses in the constitutive materials of the tube. After definition of operational specifications, the principal of them being a working pressure of 105 MPa, a steel yield limit reached at 160 MPa (proof test) and a burst at 235 MPa, a software was developed to control the prestressed hoop winding process and to predict the properties of the fabricated pipes. The theory was then validated through fabrication of representative pipes and verification of their mechanical and thermal properties, including pressure tests, long term creep in temperature and pressure fatigue cycling.
