“…Reda et al [3] indicated that 35.4%, 22.9% and 11.5% of all failures in the medium voltage subsea power cable system in Greece were related to anchoring, fishing and instability events, respectively, as shown in Figure 1. Figure 2 shows a proportion of cable faults by cause, from a database containing 2,162 records spanning the years 1959-2006 [1]. It can be seen that 14.6%, 44.4 % and 3.7% of all cable faults were due to anchoring, fishing and abrasion, respectively.…”

“…Table 2 provides recommendations that can be implemented before installing any subsea umbilical/cable. Notes: 1 Installing hard ducts around the cable will make the yarn sheath suitable. 2 Provided that the depth of the burial is larger than the diameter of the cable.…”

“…Submarine power cables and umbilicals are becoming increasingly common features of offshore hydrocarbon field development and renewable wind farms [1,3,4]. The on-bottom stability design of the subsea cables and umbilicals tend to use the ultimate limit state, accidental limit state and serviceability limit state.…”

“…Steel has long been utilised in the oil and gas sector throughout the hydrocarbon value chain, from wells and rig equipment to onshore pipelines, marine risers, subsea cables, storage tanks, and refineries [18][19][20][21][22]. Composites, on the other hand, are gaining popularity due to the multiple advantages they provide over traditional building materials, such as steel and aluminium [23][24][25][26][27][28].…”

The increasing energy demand has led to more explorations in the oil and gas industry. To achieve this, marine risers and pipelines are used to convey fluid and other resources to meet the increasing demand. In recent years, hybrid flexible composite risers have become more adaptable. Flexible risers have already proven to be a popular riser solution for various floating production systems in shallow to deepwater in many parts of the world due to their good dynamic behaviour and dependability. The hybrid flexible composite riser is made up of numerous layers of plastics, flexible pipes, composites, and steel. Some innovative monitoring methods, such as Fiber Optics Bragg Gratings (FBG), are based on a clamped composite structure with embedded optical fibre. This study presents characteristics of the monitoring techniques of composite flexible riser technology. The advantages of the monitoring techniques include aiding composite riser measurements, recording data from riser deformation, improving integrity assurance, and dependability of design from stable readings. It also proposes some design approaches as guidelines that are advised, with some policy implications.
