SUBSEA STATION Abstract of the Disclosure A subsea station or installation in which one or more rigid elongated base template frames are adapted to be perma- nently positioned on a sea floor. Each base template frame includes a plurality of framed receptor openings, each adapted to receive a module guide base for alinging and releasably connecting thereto module unitary assemblies, each of which carries selected equipment in a protected manner. Extending along each side of the base frame are elongated side structures maintenance and service, each side structure extending out- boardly of the sides of the base frame and being adapted to carry fluid conducting lines, power lines, and a rail means for guidance of a submarine capsule along the length of the base frame. Flowlines for conducting fluid to a remote platform or onshore installation are connected to the fluid conducting lines on the side structures by means of a transversely disposed pipe loop means supported from the base frame and arranged to compen- sate for expansion and contraction of the flowlines and pipelines and to provide yieldability in the makeup connections of flow- lines to the pipe loop means. The rigid base frame includes guide and support members for power control means such as elec- trical and hydraulic actuating means for operation of the equip- ment carried by the modular assemblies and by the rigid base frame. A method of lowering a rigid base template from from a work boat and assisted by a drill ship and controlling selected orientation of the base frame to and in a selected position on the sea floor.
