  • VERTICAL SUBSEA TREE ASSEMBLY CONTROL
    Publication number: 20130168101
    Abstract: A vertical subsea tree is operated by a subsea control module supplied with hydraulic and electric power from the surface through the vertical subsea tree. A landing sub is communicatively coupled to the surface with a landing sub umbilical and run to the vertical subsea tree. The landing sub engages mating penetrations on an upper portion of the master valve block of the vertical subsea tree to supply flow passages extending from the penetrations to the subsea control module through the master valve block. The subsea control module is then operated through the landing sub umbilical to control operation of the vertical subsea tree.
