Abstract: A method of determining an optimum value of at least one first parameter of execution of a process for cooling an internal space of a tank, including testing a plurality of different values of the first parameter, each phase of testing one of the values of the first parameter including cooling the internal space of the tank, the cooling power Pf or the setpoint final temperature Tc being representative of the tested value of the first parameter. The steps include loading liquefied gas into the internal space of the tank after cooling, measuring a variable P1 representative of the pressure inside the thermal insulation barrier and comparing it to at least one particular threshold, and detecting a fault if the variable P1 crosses the at least one particular threshold, and choosing, among the plurality of values tested, the optimum value of the first parameter during the corresponding test phase.

Abstract: A sealed and thermally-insulating fluid storage tank includes an angle arrangement placed at the intersection between the first and the second walls. The storage tank also includes a first and a second insulating blocks respectively retained on the first and second walls of the supporting structure and forming a corner of the thermally insulating barrier; and a metal angle structure forming a corner of the sealing membrane which is welded onto the plurality of metal plates of the first and second insulating blocks. Each of the first and second insulating blocks is associated with an adjacent insulating panel via a bridging element. Each of the first and second insulating blocks has at least one first and one second stress-relief slots extending respectively parallel and at right angles to the intersection between the first and the second walls.
