Abstract： In recent years, subsea manifold has been widely researched and applied as an important equipment for oilfield development. Also, more and more existing subsea manifolds should be replaced due to aging, external damage and so on. In order to reduce the number of subsea flange connections, a new-type hydraulic adjustable manifold is used to connect with pipeline directly in Yacheng 13-1 gas field project. Using the practical application of the project, the installation technology of the new-type hydraulic adjustable manifold is introduced. This research will also serve as reference in following subsea new-type manifold installation.
