Numerical Modelling on the Local Design of a Marine Bonded Composite Hose (MBCH) and Its Helix Reinforcement

Abstract

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.

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

“…), 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]. In the global analysis by Amaechi et al [48][49][50][51][52][53], the strength of marine bonded hoses was assessed numerically using a coupled model in ANSYS AQWA and Orcaflex, with the hydrodynamic loads from the CALM buoy structure on the riser model (submarine hoses), which was designed in a Chinese lantern configuration.…”

“…Particular applications of composites are seen in researches on composite risers [11][12][13]. The reason is that composites differ from standard materials such as steel in a number of ways, and more marine designers now have a better understanding of composite materials from flexible risers [14][15][16]. Secondly, these composite materials have weight savings and comparative stiffness-to-strength ratio, which could be advantageous in marine engineering [17][18][19].…”

Effect of Winding Steel Wire on the Collapse Pressure of Submarine Hose

“…The mechanical behavior of the floating hose was widely studied [8], yet there are few studies on submarine hoses. Gao et al (2018) [9] and Tonatto et al (2017) [10] analyzed the failure behavior of composite pipe under internal pressure load using ABAQUS software, respectively.…”

Scientometric Review and Thematic Areas for the Research Trends on Marine Hoses

“…These publication fields from the data gathered include general research, engineering, and science. An important finding from the research trend is the increased research on the reinforcements for marine hoses, as conducted in more recent studies [68,74,75,88,[216][217][218][219][220]. Additionally, based on the publication categories, journal articles, review articles, conference papers, and notes are among the publication categories.…”
