“…Further developments on composite riser designs have been made over the past three decades (Wang et al 2015;Ochoa & Salama 2005;Pham et al 2016;Amaechi & Ye 2017). Previous research by joint industry presented the mechanical properties of composite tubes (Tamarelle & Sparks 1987;Sparks et al 1988;Sparks et al 1992;Salama 1986) and composite production risers for different design load cases (Baldwin et al 1997;Salama et al 1999;Baldwin et al 2002;Johnson et al 1999). Later, Doris Engineering presented a composite riser that introduced off-axis reinforcements at an angle of +/-55° in order to reduce riser weight and improve efficiency (Picard et al 2007).…”

There has been an increase in the application of composite structures in the oil and gas industry over the past four decades. This is due to more technological advancement and an increase in demand for the oil and gas. This trend has led to offshore exploration to transit from shallow water to deep water operations. Thus the need for more lightweight composite structures to reduce the deck loads and enable ease of operation. Composite risers are important as the properties of composite materials can be harnessed to improve riser performance and weight. This will enhance the development of deep water hydrocarbon reservoirs. In this paper, numerical stress analysis of composite offshore risers for deep water applications is carried out. ANSYS ACP is used for the finite element modelling of the composite riser for six load cases. From the design, recommendations for the design of the composite riser are made.

“…In the 1980s, the Institut Francais du Petrole (IFP) and Aerospatiale of France first evaluated a composite joint for their application in offshore industry. 5,6 The riser was designed for a concrete Tension-Leg Platform (TLP) for depths within the 500-1000 m range. The riser consists of internal and external buna liners, helical wound carbon fiber layers (AE20 ), and hoop wound glass fiber layer (90 ).…”

The high strength to weight ratio, good corrosion resistance, and excellent fatigue property make carbon fiber-reinforced plastics a competitive material solution to replace steel in deepwater riser application. In this work, scaled-down composite riser joints were fabricated using a filament-winding machine. The prototypes comprise several carbon fiberreinforced plastic layers wound over an aluminum liner. They consist of a middle tubular section and two metalcomposite interface end fittings for the transfer of load between joints. A series of mechanical tests, including tension and combined tension-bending loading tests were performed to characterize their structural capacity and evaluate the improvement in performance over a purely metallic mandrel. In addition, finite element analyses incorporating elasticplastic properties of the metallic liner, interfacial failure, and complex carbon fiber-reinforced plastics failure modes were carried out. The numerical predictions are in good agreement with the experimental measurements. The experimentally verified FE framework was then extended to design and analyze a full-scale composite riser model for performance prediction to accelerate the application of composite risers by shortening product development cycle and reducing prototyping costs.

The purpose of this paper is to provide the oil and gas industry with an evaluation of composite repair and reinforcement systems to properly evaluate how composite materials should be used to repair and reinforce high pressure pipelines and offshore risers. The contents of the paper will include discussions on what critical elements should be evaluated for each composite system, items of caution and concern, and the importance of evaluation to ensure safe long-term performance. Based on a review of available research, composite materials can be used to reinforce damaged pipe materials. Specific examples include reinforcing mechanical damage subjected to cyclic pressure service and reinforcing corroded offshore risers.Insights gained through the past decade can be used to apply composite repair technology to new systems and structures. The pipeline industry has led the use of these materials as a repair method in the same way the aerospace industry adopted this technology in the 1960s and 1970s. Using a "lessons learned" approach better positions us to understand the capabilities and limitations of this technology.
