Abstract
A method for compensating the bathymetric pressure inside a subsea tank containing a liquid working fluid by using a bathymetric compensation fluid is provided. The liquid working fluid and the bathymetric compensation fluid are separated from each other by a separation layer of a separation fluid.
Claims15
A method for compensating bathymetric pressure inside a subsea tank or a tank in a system of a plurality of subsea tanks, said subsea tank or subsea tanks having an inner diameter, containing a volume of a liquid working fluid (FL) following a change or decrease of the volume of said liquid working fluid (FL), the method comprising:
- compensating said change or decrease with an equivalent volume of a liquid bathymetric compensation fluid (FC) represented by seawater, said liquid working fluid (FL) being mutually miscible with said bathymetric compensation fluid (FC),
- wherein the liquid working fluid (FL) and seawater are separated from each other by a separation layer of a separation fluid (FS), which is liquid under operative conditions and immiscible with said liquid working fluid (FL) and with said bathymetric compensation fluid (FC).
