    CIS completes Alvheim conductor installation project

    Projects and Operations // November 17, 2015

    Conductor Installation Services Ltd (CIS), an Acteon company that provides hammer services to install conductors and drive piles, has completed its second subsea piling campaign for Technip in Norway.
    CIS used its remotely operated subsea piling system, which makes it possible to drive piles as large as 36in in diameter, in water depths to 300m.

    In August, the piles were driven remotely to secure the subsea Boa Extension Manifold, which makes up an integral part of the Alvheim development, approximately 225km west of Stavanger. 

    The development, which transports oil to the UK Scottish Area Gas Evacuation System, is designed to increase oil recovery by enhancing current production rates via three new subsea well step-outs at East Kameleon, Kneler A and Boa.

    Working from the Skandi Arctic dive support vessel in maximum water depths of 130m, CIS successfully drove the four 30in manifold piles.
