This disclosure relates to an environmental compliance system installed onboard a ship. The environmental compliance system includes a computing device that records and requests authorization for overboard discharge when discharge occurs within a defined geofence. The system receives data from the ship automation system including ship location and operational valve opening commands made to discharge effluent overboard and into the surrounding water. Before the operational valve opening command can be received by the valve, the compliance box confirms ship position and compares against programmed no-discharge geofence or a plurality of geofences. When the ship is inside a no-discharge geofence, the computing device may request a manual override authorization from the responsible duty holder before completing the command so as to prevent an accidental unintended discharge. Data is securely stored by the compliance box and may also be transmitted to external cloud-based data receivers.

A system for watercraft decontamination includes a substantially water-tight vessel sized and shaped to accommodate a watercraft, the vessel containing water and including a structure adapted to facilitate disposition of the watercraft in the vessel such that the a rear portion and transom of the watercraft that are normally submerged in watercraft use are submerged in the water. The system further includes a water heating system operatively connected to the substantially water-tight vessel, so as to heat the water from the vessel, and a water circulation system operatively connected to the substantially water-tight vessel and the water heating system and adapted to circulate water between the water heating system and the substantially water-tight vessel. The water heating system is sized and configured to maintain a temperature of the water in the substantially water-tight vessel at a temperature of between approximately 100° Fahrenheit (38° Celsius) and approximately 110° Fahrenheit (43 degrees Celsius).

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.

A marine vessel may be configured with a water pump and seawater treatment equipment for use in providing a marine vessel water pumping platform for pumping water into a subsea reservoir to help maintain or increase pressure to assist with producing oil and/or natural gas. The marine vessel water pumping platform allows for the pump and seawater treatment equipment to be continuously used for pumping operations as the marine vessel may be moved between subsea reservoir sites, which helps reduce maintenance costs. The water pump may be lower in minimal flow capacity than water pumps on platforms, thereby allowing for more diversity in supporting different oil and/or gas pumping in offshore drilling operations.

A system and a method are for heat treatment of water of a vessel outside a fixed installation of the vessel. The water includes ballast water of the vessel and/or waste water from hull cleaning of the vessel. The system includes a system inlet; a system outlet; a heat application section; and a heat treatment piping system. A heat recovering section includes two parts for exchanging heat. The heat treatment piping system couples the system inlet to the system outlet via: one of the parts of the heat recovering section, the heat application section and the other part of the heat recovering section. The system does not form part of a fixed installation of the vessel.

A water treatment device including a first hydrocyclone and a biocidal fluid injector is described. The first hydrocyclone has an internal space, a water inlet for supplying water into the internal space, a base outlet for discharging at least a part of the water, and an apex outlet. The biocidal fluid injector is configured to inject a biocidal fluid into the internal space for eliminating organisms present in the water. The biocidal fluid injector is positioned such that a pressure within the injected biocidal fluid is lower than a head pressure of the first hydrocyclone.

A marine water treatment dock box system is provided. The marine water treatment dock box system securely houses a water softener, a deionizer, a high-pressure washer and a selective control system for diverting water for cleaning a docked vessel, for onboard use by the vessel, and/or for high-quality potable water production. The above-mentioned components are operatively associated to outlets disposed along the exterior of the dock box body, maintaining the security and protection of the components. The water softener may be fluidly connected to an inlet to the dock box and a three-way valve for selectively controlling the softened water to one of the following: (1) a high-pressure pump for washing a vessel; (2) to the deionizing tanks for dissolving solids for a spot-free rinse; and or (3) to an outlet to fill onboard fresh water tanks.

Techniques and systems for neutralizing discharge waters from ballast and/or cooling water biocidal treatment and disinfection systems are provided. The systems utilize, inter alia, oxidation reduction potential control to regulate the dechlorination of an electrocatalytically generated biocidal agent to allowable discharge levels in ship buoyancy systems and ship cooling water systems
