Common Requirements

[0177] Offshore charging stations (OCSs) situated in seas or in oceans may be object of various tidal ranges varying from near zero to about 16 metres (53.5 feet) and averaging about 0.6 metres (2 feet) in the open ocean. In that case, level adjustable floats or level adjustable bottom rest supporting constructions may be designed to cope with a tidal range in a selected area for placement of the OCS. Passive (e.g. slack-line anchorages, sliding anchorages, etc.) and active anchorage systems (systems with active components) may be used to provide level adjustability.

[0178] The OCSs operated/temporarily operated under water level may provide atmospheric pressure in its inner space (e.g. in the container which can be filled with dry air, nitrogen, etc.) which may be advantageous for its electronic components or it may be kept at another pressure.

[0179] The OCSs may further include further components enhancing their functionality such as installation spaces, connecting boxes, electricity meters, main switches, input/output terminals, fuse distributions, etc. The electronic control and communication components may be housed in electromagnetically shielded spaces. All electrical and electronical equipment may be particularly protected against moisture, salt water and grid to prevent failure of power and electronic components. External controls may be suitably adapted to function in offshore conditions. Subsea plugs, isolation bushings, cathodic protection and special resistive materials and anticorrosive surface treatments may be used.

Common Requirements on Offshore Charging Stations in Cold Areas

[0180] The offshore charging stations may be situated offshore in the Arctic, the Antarctic, subpolar and cold seas. In that case, components of the OCSs may be designed to be conform with cold/extremely cold/temporarily cold conditions. Offshore charging station supporting constructions may be specifically designed to be posed off shore on a solid base (e.g. ice). A special insulation of offshore power cables (which may be posed on ice), power cables may be provided. A special thermal insulation of marine rechargeable power sources (e.g. rechargeable power sources in containers) may be provided. Thermal management systems of the OCSs and the marine rechargeable power sources may require heating systems.

[0181] No limitations are intended others than as described in the claims. The present invention is not limited to the described exemplary embodiments. It should be noted that various modifications of the OCS can be made without departing from the scope of the invention as defined by the claims.

[0182] The elements described in this specification and the used terminology reflect the state of knowledge at the time of the filling of this application and may be developed in the future.

INDUSTRIAL APPLICABILITY

[0183] The present invention may provide an offshore charging station (OCS) to water vessels at least partially electrically driven. Offshore charging may increase operational ranges of the vessels and reduce the necessary on-board battery capacity. Offshore charging may relieve port traffic.

[0184] An offshore power connection near ports may minimize air pollution from ships and improve an air quality in the port area if waiting ships are not forced to idle their internal combustion engines to provide themselves with electricity for auxiliary devices.

[0185] The OCS providing a bidirectional power flow may help to improve a performance of a power grid at peak load times and bring economic benefits.

[0186] A level adjustability of the OCSs and/or primary interfaces into levels under water level may protect them in case of a malevolent attack, bad weather conditions, may help to avoid conflicts with sea transport and fishing and may position the OCS and/or the primary interface in according to water vessels' charging/discharging requirements.

[0187] The OCS in a cloud-based communication system may bring efficiency, flexibility, lower costs and lower CO.sub.2 emissions of an OCS management.

[0188] The OCS in a marine rechargeable power source system may provide a compact power source and may be utilised in the proposed swapping method.

[0189] Hydrogen powering system using renewable sources (arrays of solar cells, wind energy to electric energy converters, wave energy to electric energy converters, water currents energy to electric energy converters, tidal energy to electric energy converters) may provide a power reserve to be used for electricity production and supply by the OCS (e.g. in peak load times) or may be a principal power source.

[0190] The system may be functionally combined with a marine fuelling system and provide hydrogen fuel or another marine fuel for offshore applications.

[0191] Certain LNG fueled hybrid electric water vessels might not be allowed to bunker in a port. In such cases, a possibility of offshore charging and refuelling at a same station may be beneficial which similarly applies to hybrid water vessels using other marine fuels.

[0192] The proposed modularity may concern all elements of the OCS and can bring functional and financial benefits to the parties. Modular designs may use various degrees of modularity [e.g. component slottability, platform systems, holistic approach, etc.]. Modules may be catalogued.

[0193] The proposed swapping method and the offshore dynamic charging provided by the OCS may increase operational ranges of the water vessels at least partially electrically driven and may save time otherwise necessary for charging.
