“…Another comparison conducted on CPR models by Brown [246] showed that there is high potential for the utilisation of composite risers, as it shows good results from utilisation on flowlines and TCP pipes, as shown in Figure 15. Studies on the use of titanium alloys in CPRs for FPSO, TLP, and Truss SPAR found that titanium alloys have high mechanical attributes suitable for Composite risers [211,212,[295][296][297][298][299][300][301][302][303][304][305][306] but the configurations, fatigue, reliability, large-scale experiments and cost should also be considered [156,157,161,247,303,[306][307][308][309][310][311][312][313][314][315][316][317]. A bibliographical list of the comparative studies on composite risers is in Table 5.…”

“…In addition, in comprehensive investigations on the composite material makeup and the stack-up composition of the layers, it is very important to consider the configuration of the composite structure (like TCP flowline or composite riser), as it might be aligned vertically or in S-shape (such as steep-S, lazy-S, lazy wave, etc. ), which may vary in wave form, with respect to riser length, the sea bed type and the sea depth [23][24][25][301][302][303][304][305][306][307][308][309][310]. Application of composites have also been extended to marine hoses as marine bonded composite hoses (MBCH) [14,15,154,155,227].…”

Review of Composite Marine Risers for Deep-Water Applications: Design, Development and Mechanics

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.

“…These offshore structures and their component attachments can be made from different construction materials, ranging from steel, composites, concrete, titanium alloys, and aluminium, to additive manufactured components [ 145 , 146 , 147 , 148 , 149 , 150 , 151 , 152 , 153 ]. Steel grades are used to construct most oil and gas platforms, hence the need for robust designs [ 154 , 155 , 156 , 157 , 158 , 159 , 160 ], skilled personnel for drilling/production activities [ 161 , 162 , 163 , 164 , 165 , 166 , 167 , 168 , 169 , 170 , 171 ], reliability analysis [ 172 , 173 , 174 , 175 , 176 , 177 , 178 , 179 ], and adequate corrosion control measures [ 180 , 181 , 182 , 183 , 184 , 185 , 186 , 187 , 188 ]. Offshore operations are conducted using industry standards like ISO, BS, NIS, API, ASTM, NORSOK, etc.…”

Recent activities in the oil and gas industry have shown an increasing need for monitoring engagements, such as in shipping, logistics, exploration, drilling, or production. Hence, there is a need to have asset management of these offshore assets (or facilities). Much of the offshore infrastructure is currently approaching or past its operational life expectancy. The study presents an overview on asset management of offshore facilities towards monitoring, safe practices, maintenance, and sustainability. This study outlines the major considerations and the steps to take when evaluating asset life extensions for an aging offshore structure (or asset). The design and construction of offshore structures require some materials that are used to make the structural units, such as offshore platform rigs, ships, and boats. Maintaining existing assets in the field and developing new platforms that are capable of extracting future oil and gas resources are the two key issues facing the offshore sector. This paper also discusses fault diagnosis using sensors in the offshore facilities. The ocean environment is constantly corrosive, and the production activities demand extremely high levels of safety and reliability. Due to the limited space and remote location of most offshore operations, producing cost-effective, efficient, and long-lasting equipment necessitates a high level of competence. This paper presents the guidelines on asset monitoring, sustainable maintenance, and safety practices for offshore structures. In this study, the management of offshore structures were also presented with some discussions on fault monitoring using sensors. It also proposes sustainable asset management approaches as guidelines that are advised, with policy implications.

“…One of the most obvious of these applications is offshore oil production, which presents a substantial challenge to the product designer or offshore engineer [81][82][83]. Environmental loadings [84][85][86][87][88], hydrodynamics [89][90][91][92][93][94][95][96], hydroelasticity [97], corrosion [98], failure analysis [99], ocean wave mechanics [100][101][102][103][104][105][106][107][108], fluid content loadings [109][110][111][112][113][114][115], fatigue limits [116][117][118][119][120], reliability [121][122][123][124][125][126][127][128], and so on are all factors to consider ...…”

Offshore structures exist in a variety of forms, and they are used for a variety of functions in varied sea depths. These structures are tailored for certain environments and sea depths. Different actions for suitable equipment selection, platform type design, and drilling/production processes are required for the applications of these offshore structures, as given in Part I. This paper is the second part, which outlines various processes, loads, design approaches and project management of offshore platforms. To achieve these, proper planning must be conducted for lifting, transportation, installation, design, fabrication, and commissioning of these offshore platforms. Some historical developments of some offshore structures are presented, and some project planning routines are undertaken in this research. The ultimate goal is to provide a general overview of the many processes of offshore platform design, construction, loadout, transportation, and installation. Some discussions on the design parameters such as water depth and environmental conditions were presented. It also lists various software programs used in engineering designs. The review also includes information on cutting-edge offshore platforms and industry advancements. Ultimately, for long-term operations, various types of offshore platforms for specific seawater depths are available.
