A support device for an instrument on a loading/offloading tower of a tank of a ship is disclosed. The tower has multiple vertical masts linked to one another, pairwise, by struts extending on a strut axis, and a distal portion extending on a first axis, the distal portion being terminated by a first surface capable of forming a first surface contact with a strut extending on its strut axis substantially at right angles to the first axis. The installed first surface has a degree of freedom in rotation about the strut axis, a proximal portion extending on a second axis substantially at right angles to the first axis, linked to the distal portion. An installed fixing surface immobilized by fixing to the instrument has a degree of freedom in rotation about the second axis and a degree of freedom in translation on a third axis parallel to the second axis.

A cryogenic tank apparatus includes an inner container for holding a cryogenic medium, an outer housing surrounding the inner container, an insulation space disposed between the inner container and the outer housing, and at least one heat exchanger. The at least one heat exchanger includes at least one cold flow line through which flows the cryogenic medium held in the inner container, and at least one hot flow line in thermal contact with the at least one cold flow line and through which flows a temperature control medium in such a manner that a transfer of heat takes place between the temperature control medium and the cryogenic medium. The at least one cold flow line is arranged on an inner side of the outer housing and the at least one hot flow line is arranged on an outer side of the outer housing so that a portion of the outer housing acts as a heat transfer surface of the heat exchanger.

The invention relates to a cryogenic unit comprising: a cryogenic tank; a receptacle; a pipe comprising: a first end connected to the cryogenic tank; a second end; a first longitudinal portion; a second longitudinal portion; a bend between the first portion and the second portion; a connecting flange situated between the bend and the second end, wherein the cryogenic unit further includes: an item of fluidic equipment comprising an inlet end; and an outlet end and configured to be mounted removably inside the receptacle.

A doser for dispensing a cryogenic fluid includes a doser body configured to receive the cryogenic fluid. The dosing arm has a proximal end and a distal end and a central passage extending between the proximal and distal ends. Furthermore, the dosing arm is configured to receive cryogenic fluid from the doser body. A bayonet connection removably connects the proximal end of the dosing arm to the doser body. A dosing head is mounted to the distal end of the dosing arm and is configured to receive cryogenic fluid from the central passage of the dosing arm and to dispense the cryogenic fluid.

The invention relates to a tank comprising a container with an opening and a cover, a flexible casing lying against the interior and exterior of the container. This allows increased resistance to the penetration of sharp objects, liquid and gaseous gases can be used interchangeably and various gas types with a fossil-type and biological-type consistency can be mixed and also heated and cooled in the tank. The invention relates to tanks (1) and staged tanks of the preceding claims, characterized in that in addition to LNG, said tanks can store biological methane gas.

A sealed and thermally insulated tank for storage of a fluid, having a plurality of multilayer walls. A first of the walls has a secondary thermally insulating barrier including a first insulating panel along the intersection between the load-bearing structure of first wall and the load-bearing structure of an adjacent second wall. A second insulating panel is juxtaposed with the first insulating panel along one edge of the first panel opposing the second wall. The first wall has a secondary sealing membrane including a first corrugated metal sheet welded to a small metal plate of the first insulating panel; and a second corrugated metal sheet welded to the small metal plate of the second insulating panel.
