“…Resin polyester, carbon fibre (290 GPa), nylon 6 (PA6) and glass fibre-reinforced nylon 6/6 (PA66-GF) were also the choices of composite materials applied. The material properties were obtained from validated studies, published journal papers, company reports, material databases and previous investigations [53][54][55]. The hose in this present model measures 1 metre lengthwise.…”

“…This was implemented to keep the model design simple during the CAD stage, making the hose assembly easier while yet providing adequate simulation results. This method has been applied in modelling composite tubular pipes, ranging from CPR [31][32][33][34][35][36], to TCP/FRP composite riser tubes [51][52][53], composite pipes [54][55][56][57] and MBCH [58][59][60][61]. To replicate a localised part of the hose line receiving crush load from the reel drum, the same layering method was used to construct both a reeled and unreeled model using the same layering technique.…”

“…Figure 1 shows a field deployment of Trelleborg's Sealine floating hose. as in thermoplastic composite tubes (TCP) and composite production risers (CPR) [50][51][52][53]. This is due to their inherent properties, such as their high strength, light weight, high resistance to corrosion, high flexibility and some anisotropic characteristics.…”

With the exploration of oil trending deeper, from shallow waters to deep waters, there is a corresponding increase in the need for more sustainable conduit materials for production purposes. Secondly, there is an increasing demand for more energy from fossil fuels that are excavated with less expensive technologies. As such, short-service hoses are applied in the offshore industry. The industry has utilised composites to improve the material and solve different offshore issues. This study analyses a current problem facing the oil and gas industry at present regarding hose usage. This paper presents results from the local design and analyses of a marine bonded composite hose (MBCH), to present its result visualisations and nephographs. In this paper, the local design of a 1 m section of an MBCH was carried out in ANSYS under different loading conditions. Some design criteria were set, and other load conditions were used to simulate the model using the finite element model (FEM) approach. From this study, composites could be considered to improve conventional marine hoses. The findings of the study include the identification of linear wrinkling and damage sites on the helix reinforcement. An experimental investigation and proper content test are recommended for the bonded hose. Additionally, highly reinforced hose ends are recommended in the ends of the MBCH, as they had maximum stress and strain values. It is recommended that hose operations like reeling must be conducted under operational pressure and not design pressure, as the study shows that the design pressure could be high on the hose model.

“…Similarly in the former, OCYAN and Magma Global have also effectively configured m-pipes on CPR for pre-salt Brazil, as depicted in Figure 3. This has also led to advances in the use of TCP pipes on composite risers and related marine composite tubulars for water injection, transport, product transfer and loading and fluid discharge services [31,51,150]. Based on numerical models presented on different CPR models of well-validated composite risers with safety profiles from results of the stress analysis, conducted in ANSYS APDL [137][138][139][140][141][142] and ANSYS ACP [143][144][145][146][149][150][151][152], respectively.…”

Additionally, both researchers used different platforms-while the former used a TLP (tension leg platform), the later used a SPAR (single-point anchor reservoir) and a PCSemi (paired-column semisubmersible).…”

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.
