An ullage tank in a vertical cryogenic storage vessel that can store a liquefied gas is described. The ullage tank includes a hollow member. The ullage tank has at least one opening that allows communication between the ullage tank and an inner vessel of the vertical cryogenic vessel. The hollow member has a first open end and a second open end. The hollow member forms a vertically disposed passage through the ullage tank. The first open end and the second open end are in communication with the inner vessel. Related methods, apparatuses, systems, techniques and articles are also described.
