In order to address the requirements of scientific multidisciplinary observation in diverse small-scale regions, we have introduced the Buoy-based Cable Seafloor Observatory System (BCSOS). This system offers a distinct advantage in contexts where the use of shorter cables is feasible, contrasting with the lengthy cables typically necessary for conventional observatories. The BCSOS consists of three primary components: the Real-Time Electric Communication (RTEC) Buoy, the Power Information Transmission System (PITS), and the Seafloor Observation Subsystem (SOS). The RTEC Buoy is equipped with instruments for measuring sea surface parameters and serves as a data and power hub. The PITS, comprising a robust EM cable, connects the buoy to the SOS, which houses instruments for seafloor observations. The system is designed for a maximum water depth of 100 m and has an expected lifespan of about 5 years. The BCSOS prototypes were deployed at the Huangqi Peninsula, Fujian Province, and successfully documented the process during Typhoon Doksuri (international code 2305) at the end of July 2023. The recorded data from the BCSOS revealed a significant increase in wave height and period as the storm approached the Huangqi Peninsula. Additionally, the RTEC buoy exhibited a notable response to the large waves. The data analysis revealed a distinct pattern between the buoy response and the direction of wave propagation across various sea conditions, that the buoy’s angular movement in pitch and roll directions follows a regular elliptical distribution corresponding to different wave propagation directions. Upon thorough evaluation, future enhancements to the system are slated to concentrate on refining its design, with a particular emphasis on bolstering stability and enhancing corrosion resistance. These improvements are aimed at cementing the system’s long-term viability and performance within the challenging marine environment.
... The use of offshore platforms in deep water locations creates significant challenges for oil operators in the O & G sector, which should also be considered to ascertain asset life extensions [83][84][85][86][87][88][89][90] . High sea depths, severe weather, extremely windy circumstances, and high significant wave heights are some of these difficulties [91][92][93][94][95][96][97] . As a result, facilities management is required, which may lead to additional factors including the development, deployment, and commissioning of offshore facilities [98][99][100][101][102][103] . ...
The demand for monitoring activities has been more evident recently in oil and gas “O & G” activities such as exploration, drilling, production, logistics, or shipping. Consequently, these offshore infrastructures require asset management (or facilities management). This study seeks to understand the research pattern of publications within the domain of asset management in offshore infrastructures with the aim of determining the present state of the field’s research. The paper conducts a scientometric analysis of publications that focus on offshore infrastructures’ asset management published between 1992 and 2022. The employed search query yielded a total of 346 journal articles from the Scopus database and 43 from the Web of Science (WoS) database, respectively. The data analysis of the scientometric investigation explored research authorship, co-occurrence of keywords, number of publications, network mapping, country geographical breakdown, and literature coupling. The paper shows rising interest in monitoring and asset management in the oil and gas industry. It was concluded that the management of these infrastructures requires frequent review with the application of sustainable asset management strategies.

... They have much larger diameters than power cables, as shown by Bai and Bai (2005) and Han et al. (2021). Marine hoses for fluid transfer between offshore structures to shuttle tankers have been described by Amaechi et al. (2021aAmaechi et al. ( , 2021b, Nooij (2006), and Stearns (1975).

The present study investigates the feasibility of suspended inter-array cabling between two floating offshore wind turbines. In these cable configurations, the power cables do not touch the seabed and are kept afloat midwater below the sea surface using buoyancy modules. The floating offshore wind turbine (FOWT) used is the OC3-Hywind. The present study considers power cables of different sizes having cores with different materials, copper and aluminium. Lightweight cables have been found to be generally better suited for suspended configurations than heavy cables. Furthermore, suspended configurations using buoys show significantly lower maximum effective tensions than configurations with buoyancy modules attached. The minimum bending radius is low for configurations with buoys, whereas it is high for configurations with buoyancy modules. Power cable excursions can be significant but never exceed the mooring line anchor positions of the FOWTs. The standard deviation of the hang-off angles of the power cables from the FOWTs is more significant for load cases (LCs) at rated wind velocities than for extreme LCs where the turbine rotor stands still. It indicates that the motions of the FOWTs influence the power cable. Cost reductions can be achieved compared with a configuration where the power cable lies on the seabed.
... In their study, Yüksel et al. (2021) determined that vibration, maintenance-attitude failures and improper use, respectively, are the most common causes of pipeline failures on ships (Yüksel et al., 2021). On the other hand, Amaechi et al. (2021) stated that the most common condition leading to hose failures is the damage to the outer casing of the hose (Amaechi et al., 2021). The faults experienced in these systems may cause significant accidents that endanger life, goods and environmental safety (Han et al., 2011). ...

Ocean and marine environments face the adverse effects of climate change and environmental pollution. Maritime transportation, one of the most severe marine pollution sources because of ship-sourced operations, poses risks to the marine environment in many types and ways. A robust risk assessment should be organised to identify causal mechanisms and the resources of the pollution. In this study, the steps of ship operations that may cause marine pollution and the structure of the relations between them were established based on their expert opinions and the information contained in the literature. On this basis, the probabilities of each ship's operations that cause marine pollution are computed by the Fuzzy Bayesian Network approach. The extent of the response operation according to the level of marine pollution is determined by the Bow-tie approach. As a result, the procedures that cause funnel gas emissions are the riskiest. The study will be beneficial for the practitioners of safety and environmental management in maritime transportation to make decisions practically and strategically.
... This has led to subsequent operations seen in various exploration, drilling, and production activities [13][14][15][16]. Despite the diverse studies conducted on both conduits and subsea pipelines, the stress analysis of these subsea piping products is important to explore the characteristics of each hose/pipe product [17][18][19][20][21][22][23][24][25][26][27]. These studies consider the influence of global issues, technological changes, and climatic changes on the deployment of marine structures. ...

For over three (3) decades, there has been an increase in research on energy sources from the production of oil using flexible marine risers, such as marine hoses. Marine hoses are conduits for special use as rubberized structures with hybrid polymer composites for offshore platforms in the oil and gas industry. This scientometric study uses qualitative, quantitative, and computational approaches. Data were retrieved using a research methodology that was created for this study using the SCOPUS and Web of Science (WoS) databases. This study provides a bibliometric literature review on marine hoses with an emphasis on the advancements made in the field from recent developments, geographical activity by countries, authorship histories, partnerships, funding sources, affiliations, co-occurrences, and potential research areas. The study found that the USA had the most publications, but there were fewer co-occurrences with connections outside the cluster. Due to the difficulty of adaptation, acceptability, qualification, and deployment of marine hoses in the offshore marine industry, this topic contains more conference papers than journal papers. Therefore, more funding sources and collaborations on marine hoses are required to advance the research. This study makes a contribution to scholarship on advances made in petroleum exploration and production for (un)loading hoses.
... However, there are other applications for offshore platforms, such as dynamic positioning, exploratory activities, drilling/production, navigation, (un)loading ships, fluid transport, and bridge support [11][12][13][14][15][16]. Offshore petroleum structures are utilized for a wide range of purposes and in a wide range of sea depths and environments around the world, hence they need supporting attachments such as drilling marine risers [17][18][19][20][21][22][23], composite production risers [24][25][26][27][28][29][30], marine hoses [31][32][33][34][35][36][37][38][39][40] and mooring lines [41][42][43][44][45][46][47][48][49]. Figure 1 shows different fixed and floating offshore platforms operating in varying water depths (see details in the caption). Offshore platforms could be used as artificial reefs for many years, as they have also been used in a variety of aquatic environments. ...

Diverse forms of offshore oil and gas structures are utilized for a wide range of purposes and in varying water depths. They are designed for unique environments and water depths around the world. The applications of these offshore structures require different activities for proper equipment selection, design of platform types, and drilling/production methods. This paper will provide a general overview of these operations as well as the platform classifications. In this paper, a comprehensive review is conducted on different offshore petroleum structures. This study examines the fundamentals of all types of offshore structures (fixed and floating), as well as the applications of these concepts for oil exploration and production. The study also presents various design parameters for state-of-the-art offshore platforms and achievements made in the industry. Finally, suitable types of offshore platforms for various water depths are offered for long-term operations. An extension of this study (Part II) covers sustainable design approaches and project management on these structures; this review helps designers in understanding existing offshore structures, and their uniqueness. Hence, the review also serves as a reference data source for designing new offshore platforms and related structures.
... In addition, there are supporting attachments for these offshore installations that are used for a variety of functions and in a variety of water depths and environments globally. These components included drilling/production marine risers [17][18][19][20][21][22][23], composite risers [24][25][26][27][28][29][30], mooring lines [31][32][33][34][35][36][37][38][39], and marine hoses [40][41][42][43][44][45][46][47][48][49]. Figure 1 depicts some offshore platform installations. Offshore platforms have been employed in a variety of aquatic situations and could be used as artificial reefs for many years. ...
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.
... In addition, offshore platforms are designed to have structural components and conduits for extracting oil and gas products to provide energy [1][2][3]. However, the structural strength of aeronautical structures, subsea pipelines\cables, and marine risers is subject to certain limits, which also affect their service life and useability [4][5][6][7]. Conversely, an engineering challenge faced by pipe designers includes sustainable design methods, safe operating procedures, and better monitoring techniques [8][9][10][11]. The safety and protection of SURF (subsea cables, umbilicals, risers, and flowlines) systems have increased demand in the industry [12][13][14][15][16][17]. ...
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.
... Presently, the global demand for oil/gas products has induced the incremental need for rapid technological advances in novel materials [1][2][3][4][5][6]. Such an advancement in composite materials has been induced by the increased application of marine composites [7,8] and the shift in the fluid-transfer operations from shallow water to deep water [9][10][11][12][13]. This trend is particularly evident in the developments achieved on deep water composite risers [14][15][16][17][18]. ...
Following the rising technological advancements on composite marine structures, there is a corresponding surge in the demand for its deployment as ocean engineering applications. The push for exploration activities in deep waters necessitates the need for composite marine structures to reduce structural payload and lessen weights/loads on platform decks. This gain is achieved by its high strength–stiffness modulus and light-in-weight attributes, enabling easier marine/offshore operations. Thus, the development of composite marine risers considers critical composite characteristics to optimize marine risers’ design. Hence, an in-depth study on composite production risers (CPR) is quite pertinent in applying composite materials to deep water applications. Two riser sections of 3 m and 5 m were investigated under a 2030 m water depth environment to minimise structural weight. ANSYS Composites ACP was utilized for the CPR’s finite element model (FEM) under different load conditions. The choice of the material, the fibre orientation, and the lay-up configurations utilised in the modelling technique have been reported. In addition, the behaviour of the composite risers’ layers under four loadings has been investigated under marine conditions. Recommendations were made for the composite tubular structure. Results on stresses and weight savings were obtained from different composite riser configurations. The recommended composite riser design that showed the best performance is AS4/PEEK utilising PEEK liner, however more work is suggested using global design loadings on the CPR.
