A system that controls an impact load resulting from a fluid under an internal/external force is provided. The system senses an impact load, of a fluid under an internal/external force and attenuates the impact load. The present invention includes a floating means arranged horizontally inside an amount of fluid in an open space or in a sealed interior, a position adjustment means is vertically connected to the floating means and positioned inside the fluid, a sensing means disposed inside the fluid, on the floating means, the position adjustment means, or a structure in the periphery senses a measurement object. A controller predicts/monitors and predicts/controls fluid dynamics-related forces, hull stress, six-degree-of-freedom movements, and positions in connection with a transportation means or maritime structure. The floating means, the position adjustment means, and the sensing means are installed thereon, and use the value from the measurement object transmitted from the sensing means.

A method for fixing an assembly onto a gas vessel configured to contain a pressurized fluid. The assembly including a housing, an electronic acquisition board secured to the housing, and a strain gauge. The method including fixing the strain gauge to the vessel using a second adhesive means, the strain gauge being fixed to the vessel in such a way to allow deformation along with the vessel under the effect of the pressurized gas contained in the vessel. Electrically connecting the strain gauge and the electronic acquisition board using at least one electric cable thereby allowing the housing to be free to move relative to the strain gauge. Fixing the housing to the vessel using a first adhesive means so as to cover the strain gauge and thereby leaving a volume of air between the housing and the strain gauge and/or between the strain gauge and the electronic acquisition board.

A system includes a source of pressurized fluid, a primary pressure vessel disposed in fluid communication with the source, and a supplemental pressure vessel disposed in fluid communication with the source and in fluid communication with the primary pressure vessel. The primary pressure vessel has a first life expectancy duration and includes a first structural characteristic. The supplemental pressure vessel has a second life expectancy duration shorter than the first life expectancy duration and includes a second structural characteristic. A method uses a supplemental pressure vessel to predict impending failure of a primary pressure vessel. The method includes connecting a primary pressure vessel to a source of pressurized fluid, fluidly connecting a supplemental pressure vessel with the source and with the primary pressure vessel, and exposing the supplemental pressure vessel to a first fatigue load to cause its failure before failure of the primary pressure vessel occurs.

Some embodiments of the presently disclosed subject matter relate to a method and system for the real-time calculation of the amount of residual chemical energy in a non-refrigerated, pressurised tank containing liquefied natural gas, without a composition of the liquefied natural gas having to be determined.
