An equipment management system for a ship includes a communicating part that acquires from the ship by radio notification information including one piece of state information, or two or more pieces of state information selected from pieces of state information on at least ballast water process equipment, boiler equipment, and water desalination process equipment loaded on the ship, and a processing part that extracts the pieces of state information on the ballast water process equipment, the boiler equipment, or the water desalination process equipment from the notification information acquired from the ship, produces management information including drug information at least necessary for the ballast water process equipment, the boiler equipment, or the water desalination process equipment, and causes the communicating part to send out the management information to the ship sending out at least the notification information.

A system for presenting environment alerts for a watercraft is provided. The system includes a display, a processor, and a memory having computer program code. The computer program code is configured to, when executed, cause the processor to receive position data for the watercraft including a current watercraft position, receive environment data, determine a status of the watercraft at the current watercraft position, perform an analysis of the position data, the environment data, and the status of the watercraft, determine a notification based on the analysis, and cause presentation of the notification on the display. The notification is related to the environment data or the status of the watercraft at the current watercraft position.

The present invention relates to an oil-water separator and discharge monitoring system for a ship. The system includes a power supply unit that is provided in the ship and supplies electric power; an oil-water separation unit that receives power from the power supply unit and separates oil and water from each other; and a monitoring module for tracking, in real time, operating states of the power supply unit and the oil-water separation unit, and including a control unit, wherein the oil-water separation unit includes an oil-water tank, a connection pipe connected to the oil-water tank, an oil-water separation pump installed on the connection pipe, and an oil-water separation filter assembly for separating oil and water supplied from the oil-water separation pump, and wherein the oil-water separation filter assembly includes a housing having an inlet portion and a discharge portion for oil and water, a guide member for guiding oil and water flowing into the housing through an inlet port in a spiral direction to form a swirling flow, a first oil filter for primarily separating oil and water flowing in the spiral direction by the guide member by means of centrifugal force, an adsorption material arranged on an upper side of the first oil filter to absorb separated oil thereon, and a second oil filter installed inside the housing so as to secondarily separate the oil and water filtered through the first oil filter.

The present disclosure relates to a biocide generating system for inhibiting bio-fouling within a water system of a watercraft. The water system is configured to draw water from a body of water on which the watercraft is supported. The biocide generating system includes an electrode arrangement adapted to be incorporated as part of an electrolytic cell through which the water of the water system flows.

The present disclosure relates to a treatment system for ship ballast water, which comprises at least: a water supply device for supplying a water stream to a first tank storing solid raw material, and a first raw material supply device for mixing the solid raw material and the water stream to form a raw material aqueous solution; a first electrolysis unit that includes a first anode chamber for obtaining a first anode product by reacting the raw material aqueous solution, a first cathode chamber for obtaining a first cathode product by reacting water and cations provided from the first anode chamber, and a first diaphragm that separates the first anode chamber and the first cathode chamber; a reaction unit for obtaining a treatment agent by reacting the first anode product and the first cathode product; and an injection unit for providing the treatment agent to the ballast water.

A system and method for treating water containing at least one contaminant. The system and method include a water treatment module such as a reverse osmosis unit. An electrochemical contaminant detection system is positioned in the waste water stream of the water treatment module. The contaminant detection system includes a contaminant sensor and a water quality sensor module. The contaminant sensor measures the concentration of the contaminant in the waste water stream and the water quality sensor module measures one or more water quality parameters of the waste water stream. A processor uses an algorithm to determine the concentration of the contaminant in the feed water based on the measurements of the contaminant sensor and water quality sensor module.

A ballast water production method is provided. The method includes a filtering step that passes raw water supplied into a housing through a filter from a primary side that is upstream of the filter to a secondary side that is downstream of the filter; a volume-increasing step after the filtering step that increases a volume of water present in a space on the secondary side of the housing while the supply of the raw water into the housing is stopped; a pressurizing step after the volume-increasing step that pressurizes an inside of the housing from the secondary side while the supply of the raw water into the housing is stopped; and a rinsing step after the pressurizing step that passes a fluid through the filter from the secondary side to the primary side while the supply of the raw water into the housing is stopped.

A module for preventing barnacle formation in a marine air-conditioning system. The module comprises: i) a housing; ii) a source of irradiating light disposed in the housing, the irradiating light suitable for killing or stunning barnacle larvae; iii) a circuit assembly disposed in the housing and configured to receive electrical power from an external power supply and to provide electrical power to the source of irradiating light; and iv) a transparent window disposed in the housing to permit the irradiating light to pass therethrough. The housing is adapted to be coupled to a water filter supplying raw water to the marine air-conditioning system such that the irradiating light is transmitted into the raw water in the water filter.
