Abstract

In recent times, the need for sustainable fluid transfer has necessitated the application of bonded hoses and composite risers. It has been considered increasingly within the marine-offshore industry, with advances in loading/offloading operations, and newer offshore platforms. This paper presents a reeling study under different operational and environmental conditions. In this study, finite element modelling (FEM) was used for the design of marine bonded reeling hoses, and two wave spectra were applied to two reeling hose operations. The design assessed the load response of the marine bonded hoses during two different operations, including free-hanging (static) and reeling (dynamic/loading), and assessments were made for reinforced and mainline hoses. The findings aid an understanding on the load response, tension profiles, stress profiles, strain distribution and hose curvature of marine reeling hoses. The study showed different fluid contents affect the performance of the hose differently parametrically. It justifies the use of design specifications for reeling hose under the operation modes for marine application. The recommendations obtained from this study can assist in developing standards and guidance for use by marine hose designers and manufacturers.

对海洋波浪下卷绕和自由悬挂作业期间的海洋软管负载响应进行数值评估

近来，出于对可持续流体输送的需求，有必要应用粘合软管和复合立管。随着装载/卸载操作的进步和海上平台的更新，海洋-近海工业越来越多地考虑到了这一点。本文介绍了在不同操作和环境条件下的卷取研究。在这项研究中，有限元建模（FEM）被用于设计海洋粘合卷收软管，两种波谱被应用于两种卷收软管操作。设计评估了船用粘合软管在两种不同操作过程中的负载响应，包括自由悬挂（静态）和收卷（动态/负载），并对加固软管和主线软管进行了评估。研究结果有助于了解船用卷盘软管的负载响应、拉力曲线、应力曲线、应变分布和软管曲率。研究表明，不同的流体含量对软管性能的参数影响不同。这证明在船舶应用的操作模式下使用卷盘软管的设计规范是合理的。这项研究提出的建议有助于制定标准和指南，供船用软管设计人员和制造商使用。
