Problems solved by technology

[0005] The problem with such power supply from the pier is that it is necessary to compensate for differences in the water level in the port and the loading level of the ship when supplying power to ships moored in the port.
In addition, the readiness of such a port power supply from the pier is badly affected eg at high water levels

Embodiment Construction

[0066] figure 1 Shown is a longitudinal section of a buoyant harbor power source 1 with an internal combustion engine 2, a generator 3 driven by the internal combustion engine 2 and for matching the voltage and frequency of the current generated by the generator 3 to that moored in a harbor. The voltage and frequency of the ship's marine grid B match the converter 4 . These assemblies are arranged in or on a floatable device 5 , in particular a barge. In addition, a storage tank 6 for storing fuel or power fuel for the internal combustion engine 2, an exhaust gas treatment device 7 for purifying the exhaust gas of the internal combustion engine 2, for transferring heat of the exhaust gas of the internal combustion engine 2 to water and for Thermal coupling means 8 for supplying steam or hot water and means 19 for detecting the voltage, frequency and phase of the ship's marine electrical network B belong to said harbor power supply. The propulsion of the buoyant harbor power ...

Abstract

The invention relates to supplying ships in a harbor with external energy in order to prevent the formation of soot and CO2. For this purpose it is already known to supply ships with power from the wharfage. One problem in such a power supply provided from the wharf is that differences in the harbor's water level must be balanced for the power supply of a ship in the harbor. Furthermore, the operational readiness of such a power supply on land may be adversely affected, such as in the case of high water. In order to solve said problem, the invention proposes a buoyant harbor power supply (1), e.g. the components of the harbor power supply are disposed on or in a buoyant device, particularly a barge (11).

Description

technical field [0001] The invention relates to a buoyant harbor power source for ships according to claim 1 . Furthermore, the invention relates to a system according to claim 10 for supplying and / or cleaning ships moored in a harbour. Background technique [0002] In the world's ports, there is an increasing emphasis on reducing emissions. This also applies to the navigation of the ship. It is common practice at present that the ship meets its current demand in port by means of its own generating set, usually one or more diesel generators. Since these machines are optimized for burning heavy diesel ie HFO and partly also burn marine diesel ie MDO in port, these diesel generators produce soot, NOx, CO2 and SOx quantities that cannot be underestimated. [0003] In order to prevent soot, NOx, carbon dioxide and SOx formation, ships in ports are supplied with external energy as discussed in accordance with EU directives 1999 / 32 / EC and 93 / 12 / EG. For this purpose, it is know...
