脐带缆是油气开采水下生产系统中的关键组成部分,其截面由光缆、电缆、钢管及填充材料等构成.由于构件的性能存在一定差异,所以其排布形式会使得脐带缆性能存在较大差距.综合考虑到截面紧凑性、平衡性和热源分散性,建立了多目标优化模型.基于该模型构建物理模型,并采用拟物算法对包含等径构件的脐带缆截面进行布局设计.前期研究表明,功能构件之间的相互约束会在优化后截面中产生空缺区域,为满足脐带缆设计规范中对截面布局密实的要求,提出基于图像识别的截面构件自动填充策略,并将其融入布局优化流程.最后,以一根脐带缆为例,通过拟物算法得到最优布局后,利用填充策略完成截面填充设计.通过与初始截面对比,验证了所提出的自动填充设计算法的有效性,为脐带缆截面填充设计提供有效参考.

As a key component in the subsea production system for oil and gas exploitation, a marine umbilical consists of optical cables, electrical cables, steel tubes, and filler bodies. The difference of materials and dimensions between the components leads to a great difference in their mechanical properties, and the different layouts cause a large gap in the performance of an umbilical. Considering the compactness, balance, and heat source dispersion of the cross-section, a multi-objective optimization model is established in this paper. Based on the quasi-physical algorithm, the layout design of cross-section of an umbilical containing equal-diameter components is conducted. Due to the mutual constraints between functional components, the optimized cross-section will have large gap. In order to meet the requirement of dense cross-sectional layout in the umbilical cable design specification, a strategy for automatically filling filler bodies based on image recognition is introduced, in combination with the layout optimization process. Finally, taking an umbilical as an example, the filling strategy is utilized to complete the design of cross-sectional filler bodies after obtaining the optimal layout through the quasi-physical algorithm. The algorithm is validated by comparison with the initial cross-sectional layout, demonstrating its effectiveness as a reference for the design of cross-sectional filler bodies of umbilicals.
