A sealed and insulating tank for storing and/or transporting a liquefied gas has a sealed and self-supporting internal reservoir with an interior surface for contacting the liquefied gas and an outer surface with an insulating barrier covering the outer surface of the internal reservoir. The insulating barrier is fixed to the internal reservoir. An outer sealed membrane covers an outer surface of the insulating barrier, and the outer sealed membrane has a metal sheet provided with bellows or corrugations. The outer sealed membrane is fixed to the insulating barrier or the internal reservoir. An intermediate space between the internal reservoir and the outer sealed membrane contains a gaseous phase under depression in order to press the outer sealed membrane against the outer surface of the insulating barrier.

A sensor mounting assembly is configured for use with a vessel arrangement including at least four vessels. The assembly includes first and second elongated frame members, first and second rollers, and first and second sensors. The first sensor is attached to the first elongated frame member and is configured to contact the surface of the first vessel upon actuation in a first direction. The second sensor is attached to the second elongated frame member and is configured to contact the surface of the second vessel upon actuation in a second direction that is substantially orthogonal to the first direction. This disclosure also describes a method of mounting at least six sensors for use with a vessel arrangement including at least four vessels, the vessel arrangement disposed in a container in a two-by-two stacked configuration having a central space.

A regasification facility, regasification systems and methods for import, offloading and regasification of liquid natural gas from liquid natural gas carriers is provided. The regasification facility is configured to provide increased flexibility in the construction so as to enable substantial reductions in construction times and costs of the construction of the regasification facility to be constructed and brought into operation, and to be further scaled up quickly and efficiently versus traditionally constructed and operated land based regasification plants and/or floating storage and regasification units.
