A subsea vessel includes an outer layer of non-corrosive material and an inner layer of high-strength material that both corroborate in a subsea environment to withstand external pressure and prevent corrosion. The subsea vessel further includes a cavity surrounded by the inner layer and outer layer for providing storage in and protection from the subsea environment. The cavity is accessible via an opening that extends through the inner layer and the outer layer. The opening can be opened and closed with a cooperating cap that impermeably seals the cavity. The cap may include a number or connection mechanisms for being selectively secured to the opening. In addition, the cap may include a portion formed of a high-strength material and a portion formed of a non-corrosive material.

A module connector for holding and/or transporting of bulk goods for connecting a first container module to a second container module, the container modules being joined together have an aligned container inner surface, a first seal arranged between the first container module and the second container module, a second seal arranged between the first container module and the second container module, the first seal is arranged in a recess and the second seal in a groove, the first seal forming an inner seal and the second seal forming an outer seal, the second seal produces a sealing of the interconnected container modules especially if the first seal fails, the first seal has at least one crimp region, which is crimped by a first and/or second flange surface such that one end face of the first seal is situated flush and/or aligned with the container inner surface without forming a cavity in the area of the end face of the first seal as well as a seal element for the module connector for the sealing of the container.

An object of the present invention is to provide a cooling water storage reservoir capable of passive cooling a reactor containment building in order to prevent the reactor containment building from being re-pressurized and reheated in the event of a serious accident. The cooling water storage reservoir comprises: a storage tank forming a first storage space in which cooling water is stored; a compartment tank disposed inside the storage tank and forming a second storage space separated from the first storage space; and an inlet which is provided in the compartment tank and allows the cooling water in the first storage space to naturally flow into the second storage space when the water level in the second storage space decreases.
