Subsea pipeline with multiple access nodes

A system, comprising:

• a pipeline;
• a plurality of future access node structures affixed to the pipeline prior to deployment of the pipeline subsea, said future access node structures being axially spaced apart from one another along the pipeline,
• wherein each of the plurality of future access node structures comprises:
• a body having a substantially planar upper surface;
• an opening extending from the planar upper surface, through the body, to an interior of the pipeline;
• and
• a pressure-barrier device positioned within the opening, entirely below the planar upper surface, wherein the pressure-barrier device is selected from a group consisting of a plug and a membrane, and wherein the pressure-barrier device sealingly engages an inner surface of the opening;
• a support block positioned around the pipeline, wherein the support block comprises:
• a strap recess formed within an upper surface of the support block;
• and
• a slot extending through the support block and below the upper surface of the support block;
• a utility line extending through the slot, wherein the utility line is coupled to the pipeline by the support block;
• and
• a strap extending through the strap recess, partially covering the utility line, and wrapped around an outer diameter of the pipeline.
