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 method of sanitising seawater at a subsea location comprises: exposing flow of seawater in a treatment reactor to UV radiation that sanitises the seawater without the addition of sanitising chemicals; and outputting the sanitised seawater from the reactor into a subsea structure such as a pipeline or a wellhead. The flow of seawater may be exposed to successive emitters of UV radiation such as pressure-compensated LEDs. The efficacy of sanitisation may be determined by: injecting a tracer fluid into the flow of seawater upstream of the reactor; and, downstream of the reactor, sensing transformation of the tracer fluid due to exposure of the tracer fluid to the UV radiation in the reactor.

A system has been developed to treat ballast water by selectively dissociating target molecules into component products compositionally distinct from the target molecule, wherein the bonds of the target molecule do not reform because the components are no longer reactive with each other. Dissociation is affected by treating the target molecule with light at a frequency and intensity, alone or in combination with a catalyst in an amount effective to selectively break bonds within the target molecule. Dissociation does not result in re-association into the target molecule by the reverse process, and does not produce component products which have a change in oxidation number or state incorporated oxygen or other additives because the process does not proceed via a typical reduction-oxidation mechanism.

A system of fluid sterilization of fluid of vessel is provided, such as sterilization of ballast water for a water vessel. The system incorporates a heating section to heat pressurized fluid above prescribed thresholds for temperature, pressure, and duration (e.g., dwell time) to achieve desired levels of sterilization, including a heat exchanger to both (a) preheat fluid prior to entering the heating section and (b) cool outflow of the heating apparatus, in which fluid travels through the apparatus by operating valves forward and aft of the heating section in a controlled sequence to facilitate flow through the system while maintaining prescribed pressure and temperature profiles. The system operates within prescribed ranges of pressure and temperature to achieve the desired level of sterilization without need of maintaining a fixed temperature or a fixed pressure within any portion of the system, including the heating section.

A water purification system includes a high temperature water tank, a flameless heat source, a cylindrical vessel (hydrocyclone nest), a first pump, a steam production meter, and a steam condenser and heat exchanger. The contaminated water is heated within the high temperature water tank using the flameless heat source. The heated contaminated water heats the cylindrical vessel and one or more sets of hydrocyclones. The heated contaminated water is pumped into the cylindrical vessel such that the heated contaminated water enters a tangential inlet of the hydrocyclones, the hydrocyclones separate the heated contaminated water into steam and solids/concentrate, the steam exits through an overflow of the hydrocyclones and a first outlet of the cylindrical vessel, the solids/concentrate exit through an underflow of the hydrocyclones and a second outlet of the cylindrical vessel. The steam is condensed into purified water using the steam condenser and heat exchanger.

The present invention relates to an apparatus for reducing greenhouse gas emission in a vessel cooperated with exhaust gas recirculation (EGR), and a vessel including the same, in which NO.sub.X generation is reduced, which is the original purpose of EGR, while maintaining existing EGR, SO.sub.X as well as CO.sub.2, which is the representative greenhouse gas, are absorbed and converted into materials that do not affect environments, and the materials are discharged or stored as useful materials, thereby preventing corrosion of an engine and improving combustion efficiency.

The present invention is a system for treating effluent from robotic equipment used to remove marine biofouling, primarily targeting organisms such as orange cup coral, which collect on hulls of floating units for transporting oil and derivatives thereof, or on production and exploration platforms. The system involves separating the flow into two elemental phases: solid and liquid. In the solid-phase flow, treatment is carried out in steps essentially comprising particle-size reduction, direct oxidation, oxidation residence, separation, drying, temporary hermetic storage, packaging, and automatic transportation for final storage. The liquid phase includes a step of centrifuging, adsorption, inerting, and discharge of treated effluent into the sea in accordance with environmental law. The entire system is automated to minimize manual actions and interventions, and is programmed to run without interruption as a function of the flowrate of raw effluent.

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.

The invention relates to a method and system for treating flue gases comprising generating a superimposed DC time-varying pulsed wave by superimposing a direct current on a low frequency time-varying pulsating electromagnetic wave signal, providing a treatment medium comprising water, using the superimposed DC pulsed wave to treat the treatment water medium, negatively charging the treated treatment water medium, and passing the negatively charged treated treatment water medium into a chamber containing flue gas such that the negatively charged treated treatment water affects the gas components of the flue gas and converts the gas components respectively to one or more of sulphates, nitrogen, oxygen, bicarbonates, carbonates and carbon, which can then be removed with used treatment water or exhaust gases. In particular, the invention relates to methods and systems for applying a superimposed time-varying frequency electromagnetic wave comprising both AC and DC components in a pulsating manner to enable the removal of pollutant gases from flue gases.
