6月11日，中國石油發(fā)布消息，中國自主研發(fā)的多功能模塊化海床挖溝機，完成了孟加拉國首條海洋管道工程100多公里的管道鋪設(shè)，創(chuàng)造了“海陸定向鉆穿越”和“航道后深挖溝”兩項世界紀錄。據(jù)悉，通常海底管道埋深一般在1.5米至3米，達到海床下5米，在業(yè)內(nèi)已屬于高難度工程。此次海底管道因穿越航道，最深埋深要達到11米，施工難度在世界海工史上也前所未有。 China's self-developed multi-functional modular seabed trencher completed the laying of over 100 kilometers of the first offshore pipeline project in Bangladesh, setting world records in "sea-land directional drilling crossing" and "deep-sea trench behind the channel," the China National Petroleum Corporation (CNPC) announced Saturday.
