海洋工程中电缆载流量敷设校正系数选取方法探讨

Discussion on the Selecting of Correction Factors for Cable Grouping in Offshore Oil Engineering

随着海洋油气田规模逐步增大,海上平台功率密度逐步增大,电缆敷设也越来越密集。IEC 60092-352附录B电缆载流量计算方法已经在船舶及海洋工程领域使用多年,通过对国内外标准规范中电缆载流量敷设校正系数及电缆载流量计算对比,指出IEC 60092-352附录B电缆载流量计算方法具有一定的局限性,最后给出了海洋工程中电缆敷设方式选择及校正系数选取的建议。

With the rapid development of offshore oil and gas, the power density of the offshore platform is gradually increasing, and the cables in the cable tray are becoming more and more intensive. The correction method for group-ing cables in IEC 60092-352 Appendix B has been used for many years in the ship and offshore oil engineering. Ac-cording to the comparison of the correction factor for cable grouping and cable current rating calculation in the Stand-ards at home and abroad, the deficiency of the correction method for grouping cables in 60092-352 IEC appendix B is pointed out. Finally, the suggestion of cable laying mode and the selection of correction factor in offshore oil engineer-ing are presented.
