12月(yue)15日，中(zhong)國石油(you)冀東(dong)(dong)油(you)田南堡(bao)1-2人工(gong)島(dao)北(bei)側環島(dao)路旁，弧光閃耀，焊花飛濺(jian)，南堡(bao)1-3人工(gong)島(dao)至南堡(bao)1-1人工(gong)島(dao)的海底(di)管(guan)道預(yu)制工(gong)作正在這里(li)火熱(re)展開，由此拉(la)開冀東(dong)(dong)南堡(bao)油(you)田第二條海底(di)管(guan)道工(gong)程施工(gong)的序幕(mu)。
南堡(bao)1-3人(ren)工(gong)(gong)(gong)島至(zhi)南堡(bao)1-1人(ren)工(gong)(gong)(gong)島海(hai)底管(guan)(guan)(guan)道包括一條(tiao)混輸(shu)管(guan)(guan)(guan)線(xian)(xian)和一條(tiao)供水管(guan)(guan)(guan)線(xian)(xian)，由(you)南堡(bao)1-3人(ren)工(gong)(gong)(gong)島通向(xiang)南堡(bao)1-1人(ren)工(gong)(gong)(gong)島，長度均為7.2千米(mi)(mi)。混輸(shu)管(guan)(guan)(guan)線(xian)(xian)為雙層(ceng)管(guan)(guan)(guan)線(xian)(xian)，內管(guan)(guan)(guan)直徑(jing)為406毫米(mi)(mi)，外管(guan)(guan)(guan)直徑(jing)為559毫米(mi)(mi)，采用(yong)(yong)浮拖法鋪設(she)。供水管(guan)(guan)(guan)線(xian)(xian)為單(dan)層(ceng)管(guan)(guan)(guan)，直徑(jing)為355毫米(mi)(mi)，采用(yong)(yong)混凝土配重和鋪管(guan)(guan)(guan)船法鋪設(she)。兩條(tiao)管(guan)(guan)(guan)線(xian)(xian)同時施工(gong)(gong)(gong)，計(ji)劃于2009年6月底達到投產(chan)條(tiao)件。
南堡1-3人工島(dao)是冀東油(you)田(tian)2009年產能建(jian)(jian)設(she)主戰場之一，目前已(yi)經(jing)完成島(dao)體吹填(tian)，正在(zai)進行(xing)地基(ji)處理，登陸點建(jian)(jian)設(she)進入收尾階(jie)段(duan)，預計2009年2月底可達到鉆機上島(dao)條件。為(wei)確保南堡1-3人工島(dao)產能建(jian)(jian)設(she)順利實施，南堡油(you)田(tian)2號平臺建(jian)(jian)設(she)項目部超前謀劃，超前進行(xing)材料(liao)采購和(he)海底電(dian)纜鋪設(she)，目前電(dian)纜鋪設(she)和(he)管道加工已(yi)經(jing)完成，爭取在(zai)今年冬天完成全部管線預制工作，并在(zai)海況(kuang)條件適合時及時出海施工。
