[0060] Referring to Figure 3, a 2D plan view of the arrangement of the hydrogen production system mounted on a floating platform can be seen.

[0061] The equipment of the floating offshore wind-integrated marine green hydrogen production system for the floating offshore wind-integrated marine green hydrogen production device is mounted on a semi-submersible floating system.

In addition, the available space may also be limited depending on the shape of the floating system. Furthermore, the production system of the floating offshore wind-integrated marine green hydrogen production device must be positioned considering the system capacity, system weight, and system layout in a limited space, as the center of gravity is important to stably maintain the platform from external forces.

[0062] The floating offshore wind power generation system of the device for producing marine green hydrogen with floating offshore wind power is designed to be centered on the stern by arranging the hydrogen production system in the stern because the wind power generation turbine, blades, and tower are installed in the bow section, which concentrates the weight there.

[0064] Because space for the floating offshore wind-powered integrated marine green hydrogen production device is limited, each system can be configured in a modular design in the form of a container.

[0065] The hydrogen production system for floating offshore wind power-integrated marine green hydrogen production requires additional reinforcement materials, etc., as the entire facility is placed on the platform deck, which requires a large area to occupy. To minimize the area occupied, the AC / DC converter, DC / DC converter, and water electrolysis converter are placed in a two-layer stacked structure, which has the advantage of reducing the area occupied.

[0066] The device for producing marine green hydrogen integrated with floating offshore wind power has NaS batteries stacked in three layers within the empty space of the column, reducing the area occupied on the floating platform deck and ensuring stability by aligning the center of gravity.

[0067] The device or hydrogen production system for producing marine green hydrogen integrated with a floating offshore wind power plant can be arranged so that each facility has a separate work space, taking into account the maintenance of the components inside the modular container.
