A method of installing a header pipe jointat a subsea structureis provided, comprising providing a header pipe jointhaving at least one valveinstalled therein and connecting the header pipe jointinline of a spoolor pipelineprior to lowering the header pipe jointto the subsea structure. The header pipe jointis then lowered to the subsea structure, and the valveis connected to the subsea structure (e.g. a subsea production system of the subsea structure such as a xmas tree) with a connection bridge e.g. a choke bridge. This provides a fluidic connection between the subsea structure and the header pipe joint. The subsea structurecomprises a foundation, e.g. suction anchors, which provide support for both a wellhead and the header pipe joint. A subsea assembly comprising a subsea structure, header pipe jointand connection bridgeis also provided.
