Abstract
This paper discusses the development and makeup of unbonded flexible pipe technology for the Offshore and Onshore Oil & Gas Industry. Focus is given to the design, manufacture, and testing of unbonded flexible pipe to meet the challenges of shallow and deep water floating production systems. Flexible pipe is a multi-layer structure of helically wound metallic wires and tapes and extruded thermoplastics. Layer by layer, the typical materials employed in the flexible pipe are described along with their functional requirements within the overall pipe structure. From micro finite element analysis to predict the behaviour of the layers of the pipe to global finite element analysis which takes into consideration the environmental and vessel loading on the pipe structure are considered herein. Functional and design requirements are described, along with material selection and manufacturing requirements. The documentation generated with the product design and manufacture is presented. Finally the factory acceptance tests performed prior to load out are described, as well as packaging and a brief overview of installation.
