    Recently, Hengyi (Brunei) Single-point Mooring Project of COOEC is getting prepared for pipe laying. The super-large pipe diameter of 44" in the Project refers to the largest that is laid by COOEC among overseas pipe laying projects so far. For ensuring successful construction, the master work boat “Lanjiang” performed all-round commissioning on stinger and other key equipment under high temperature for days to get ready for construction in advance.

    Since the Project was commenced in March 2018 till now, “Lanjiang” has successfully finished the installation and tension test of 6 anchor piles and anchor chains in the construction sea ara.

    For the Project, a set of CLAM single-point mooring system will be installed. With original discharging and loading capacity of over 300,000 t, it realized five “first” breakthroughs in terms of installation technology, including independently developed large-diameter and long-distance submarine pipe landing dragging technology, computational analysis technology of large-diameter and long-distance submarine pipe landing dragging, as well as binding and fixing technology of providing submarine pipe with reserve float buoyancy.

    In the meantime, the Project achieved domestication of anchor chain system and jacking-up system, and also promoted the domestication process of 5 achievements including anchor cable system and flexible pipe system.
