A pipeline connection assembly includes a landing platform and rotary or swivel connection hub which may be attached to a pipeline branch, termination, or manifold. The landing platform is mounted so that it may be rotated about the connection hub. This permits the installation of a subsea connection on a near level platform and allows the pipeline to be laid subsea with greater roll angles than would be acceptable otherwise. Orientation of the landing porch horizontally removes the requirement to manufacture the connection jumper to compensate for the roll differences in the hubs. In the preferred construction, the elevation of the platform can be adjusted by a remotely operated vehicle (ROV) and locked into place once the adjustment is completed.
