Cryogenic pipeline configurations and methods

A cryogenic pipeline comprising:

• a bulkhead having an inner transition element, and distinct first and second outer transition elements coupled to and at least partially surrounding the inner transition element;
• wherein the inner transition element is coupled to and between a first cryogenic pipeline and a second cryogenic pipeline to thereby form a continuous conduit that allows transfer of a cryogenic product from the first cryogenic pipeline through the inner transition element to the second cryogenic pipeline;
• wherein the distinct first and second outer transition elements are coupled to a first and a second jacket pipeline respectively, and wherein the distinct first and second outer transition elements are coupled to the first and second cryogenic pipelines via the inner transition element, respectively, to thereby allow transfer of contractive thermal stress load in the first and second cryogenic pipelines into compressive stress load in the first and second jacket pipelines, respectively;
• and
• wherein at least one of the inner transition element and the first and second cryogenic pipelines are at least partially enclosed by an insulating material.
