“…The inclusion of the set of 105 lines leads to an asymmetric response in the coupled situation. This aspect was initially identified by [15]. For uncoupled conditions, however, situation 1, representing a portside wave, and situation 2, representing a starboard wave, present the same RAO.…”

“…The present work proposes to take the next step towards a coupled dynamic analysis methodology, initiated by [15,16], but this time focusing on the fatigue context. Special attention is dedicated to applications on deepwater and ultra-deepwater scenarios involving FPSOs with numerous mooring lines and risers featuring a riser balcony on one side.…”

“…For such applications, ref. [15] highlighted the substantial influence of nonlinear stiffness, inertia, and particularly damping effects from the lines on the hull dynamic behavior. Those studies have shown that the motions of the top connections of the risers are influenced by the coupling of the lines to the hull, resulting in asymmetric responses of vertical displacement in these top connections and an asymmetric response of the roll motion.…”

This study introduces a Finite Element (FE) hybrid methodology for analyzing deepwater offshore oil and gas floating production systems. In these systems, flexible risers convey the production and are connected to a balcony on one side of the platform. The proposed methodology couples, in a cost-effective manner, the hydrodynamic model of the platform with the FE model that represents the risers and the mooring lines, considering all nonlinear dynamic interactions. The results obtained and the associated computational performance are then compared with those from traditional uncoupled analyses, which may present inaccurate results for deepwater scenarios, and from fully coupled analyses that may demand high computational costs. Moreover, particular attention is dedicated to integrating global and local stress analyses to calculate the fatigue resistance of the flexible riser. The results demonstrate that the coupled global analyses adequately capture the asymmetric behavior due to all risers being connected to one of the sides of the platform, thus resulting in a more accurate distribution of fatigue damage when compared to the uncoupled methodology. Also, fatigue life is significantly affected by adequately considering the coupling effects.

“…As seen in Figure 4, it was observed that the highest generated publications were 19 publications in 2020, followed by 14 publications in 2014 and 2016, then 13 documents in 2019, and 12 documents in 2021. However, there are limited publications found on the installation of marine hoses [160][161][162][163][164][165][166][167][168][169][170] compared to other marine systems [171][172][173][174][175][176][177][178][179][180]. As observed in Figure 5a, the highest publications by subject area were in engineering, with 212 publications (42.7%), energy, with 99 publications (19.9%), earth and planetary sciences, with 46 publications (9.3%), environmental science with 23 publications (7.4%), chemical engineering with 23 publications (4.6%), materials science with 21 publications (4.2%), and agricultural and biological sciences with 16 publications (3.2%), among other subject areas.…”

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

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.
