ABSTRACT:
A hose assembly is described for use in the transference of cooled liquified gas to a vessel, in a system that requires the flexible hose to lie in the water. The hose assembly includes a flexible inner hose forming a central passage through which liquified gas can pass towards the vessel and having walls that are permeable to the bleeding of vapor therethrough, to avoid damage by expanding liquid droplets that find their way into the inner hose wall. The assembly also includes an outer hose with substantially impermeable walls, the outer hose surrounding the inner hose and leaving an annular passage between them which can receive the vapor permeating the inner hose. The annular passage also can be used to carry vapor from the vessel back to a shore-based installation which reliquifies it.
