Abstract: A subsea production system effects line connections between a manifold and adjacent satellite wells. The radial distance between each well (37) and a central manifold (38) is reduced to an operational minimum. The manifold is provided with connection terminals (45) including at a lower portion, a hydraulic type connector (47), and at an upper portion a reentry mandrel (50). A supporting structure (53) of the connection terminal (45) consists at the lower portion of a mud mat (54) centrally of a waiting mandrel (55). A lateral structure (56) is provided at an upper portion with eyelets (57), and the upper portion mounts a reentry funnel (58). Various methods are effected for completing line connections between such a manifold (38) and adjacent satellite wells (37).
