Abstract: Storage tank comprising—an outer container (2) having a first closable opening (23), and—an inner bladder container (3) disposed within said outer container (2) and having a second closable opening (30), said outer container (2) and inner container (3) being sealed with respect to each other, said inner container (3) being adapted to be filled and or emptied with a liquid through said second closable opening (30), a space (8) between the outer container (2) and the inner container (3) being adapted to be filled with liquid through the first closable opening (23). The outer container (2) is rigid with at least one flexible portion incorporated in the rigid outer container and configured to flex so as to expand and contract to compensate volume variations caused by pressure and or temperature variations to which the storage tank (1) is subjected.

Abstract: The present invention provides a seal comprising an elastomeric composite, said composite comprising an elastomeric polymer and a negative thermal expansion (NTE) filler, the NTE filler has a coefficient of thermal expansion (CTE) lower than ?6×10-6 K-1 within a temperature range of 220-293 K and is present in an amount of 0.01-50 volume % based on the total volume of the elastomeric composite at 20° C.

Abstract: The present invention provides a seal element made in an elastomeric composite, said material comprising an elastomeric polymer and a phase change material (PCM), wherein the PCM is able to provide thermal energy to the elastomeric polymer upon cooling to the phase transition point of the PCM.

Abstract: A device for cooling and lubricating a subsea device (1) which includes an electric rotary machine (4) and a fluid-rotation machine (6-8) drive-connected (5) thereto, which electric rotary machine (4) has a lubrication/cooling circuit includes a cooler (11) exposed towards the surrounding seawater, and where the fluid-rotation machine (6-8) has a fluid pressure at the end facing towards the electric rotary machine (4). The lubrication/cooling circuit (12, 11, 14) is pressure-impacted by the fluid pressure at one point (19, 20) in the lubrication/cooling circuit outside the fluid-rotation machine (6-8).
