Great video..... One question when you pump out of the LNG storage vessel are you not pulling a vacuum in your storage vessel ? On your diagrams I don't see a vaporizer used to replace the space of liquid being pumped out.
Thanks for the quick response, but I didn't see a vapour return hose / line so as per your video the pressure in the ship fuel tank is maintained through top and bottom filling. The LNG Storage tank if it is pumped out with no vapour return will cause a vacuum in the LNG Storage vessel. So I presume there must be a ambient air vaporiser somewhere (not shown on video) used vaporize a small amount of LNG into natural gas and return to the LNG storage vessel to ensure that a vacuum is not formed. Unless I'm missing something? Or part of the safety system of the LNG tank
