平台附近海底电缆修复方法及工艺研究

Research on Repair Method and Technology of Submarine Cable near Platform

近年来,平台附近活动的船舶数量不断增加,船舶抛锚、走锚等造成海缆刮伤、刮断事故已经成为了海缆故障的主要原因。当海缆发生故障时,最有效的办法是切除故障处海缆,并在切除的故障处敷设一段新海缆,铺设的新海缆两侧分别以海缆接头的形式与旧海缆连接,但海缆修复后整段海缆存在2个海缆接头,会给之后的海缆运营带来一定的风险,目前已有海缆接头漏水的案例。如果直接废弃并回收故障点至最近平台的海缆,重新从平台处铺设新海缆至故障点,再以海缆接头的形式连接新旧海缆,则修复的整段海缆上只有一个海缆接头,减小了海缆出现故障的风险。

In recent years,the number of ships moving near the platform had been increasing,and the accidents such as ship anchoring and anchoring causing submarine cables had become the main cause of submarine cable failures.When the submarine cable fails,the most effective method was to cut off the submarine cable and lay a new submarine cable at the fault.Both sides of the new submarine cable were connected to the old submarine cable in the form of submarine cable connectors,but there were 2 submarine cable connectors in the entire section of the submarine cable after the submarine cable was repaired,which would bring certain risks to the subsequent submarine cable operation.At present,there were cases of leakage of the submarine cable joints.If the submarine cable from the fault point to the nearest platform was directly discarded and recovered,a new submarine cable was laid from the platform to the fault point,and then the new and old submarine cable was connected in the form of a submarine cable connector,then there was only one submarine cable connector on the repaired entire section,reducing the risk of submarine cable failure.
