“…In addition to having a lower density, FRP composites have a higher strength-to-weight ratio [231][232][233][234][235][236][237][238][239][240]. Excellent damping, thermal insulation and corrosion and fatigue resistance will result in greater savings by lowering maintenance costs by using composites [241][242][243][244][245][246][247][248][249][250][251]. However, appropriate testing and qualification is required to successfully use composite materials in marine risers.…”

In recent times, the utilisation of marine composites in tubular structures has grown in popularity. These applications include composite risers and related SURF (subsea umbilicals, risers and flowlines) units. The composite industry has evolved in the development of advanced composites, such as thermoplastic composite pipes (TCP) and hybrid composite structures. However, there are gaps in the understanding of its performance in composite risers, hence the need for this review on the design, hydrodynamics and mechanics of composite risers. The review covers both the structure of the composite production riser (CPR) and its end-fittings for offshore marine applications. It also reviews the mechanical behaviour of composite risers, their microstructure and strength/stress profiles. In principle, designers now have a greater grasp of composite materials. It was concluded that composites differ from standard materials such as steel. Basically, composites have weight savings and a comparative stiffness-to-strength ratio, which are advantageous in marine composites. Also, the offshore sector has grown in response to newer innovations in composite structures such as composite risers, thereby providing new cost-effective techniques. This comprehensive review shows the necessity of optimising existing designs of composite risers. Conclusions drawn portray issues facing composite riser research. Recommendations were made to encourage composite riser developments, including elaboration of necessary standards and specifications.

“…In the practical application of composite repair systems, the diversity in material categories and installation procedures may lead to poor bonding between the elements. Nevertheless, a non-slip perfect bonding assumption has been implemented in several numerical investigations, 6,8,[35][36][37][38] leading to a cooperative agreement with the experimental data and a significant decrease in simulation expenses. One composite patch layer with the equivalent repair thickness is only applied according to a perfect bonding assumption and the proposed theoretical approach.…”

While around 60% of pipelines transmitting oil and gas worldwide experience corrosion and metal loss, the composite repair technique has become a popular option developed in recent decades. Employing a theoretical methodology, this study deals with corroded metallic pipes repaired by composite repair systems such that the focus is the impact of elastoplastic deformations on the failure pressure. In this methodology, the elastoplastic strains are taken into account by employing the bilinear isotropic hardening plastic flow theory with the von Mises yield criterion. Three modes are recognized based on the region where failure occurs, and the results are presented. The findings revealed that when the failure happens in the defect region, the proposed formula estimates the failure pressure more accurately than when it occurs either far from the defect or in the composite sleeve. Moreover, studying the bonding strength between the pipe, infill material, and composite patch shows that the interface bonding strength between the pipe and the polymer filler plays a more significant role than the interface bonding strength between the polymer filler and the composite repair. The results of this study can assist maintenance engineers in better evaluating the reliability of composite repaired pipelines.

“…(3) Demagnetize the specimen. The flexural stress in the four point bending test can be estimated from simple beam theory [48], the maximum stress when a 50 kN load was applied at each loading roller being 462 MPa. Instead of loading the specimen direct to this maximum stress, the load was increased in three steps:…”
