At De Nora, we deploy a century of environmental leadership for shipowners and operators – providing comprehensive ballast water management solutions to help ensure their vessels’ compliance with International Maritime Organization (IMO) and United States Coast Guard (USCG) regulations designed to stop the spread of invasive aquatic species.
One of the ways De Nora deploys its suite of BWM technologies for shipowners is through the Hyde GUARDIAN® BWMS, which offers a variety of efficient, cost-effective benefits vessel operators depend on for proper ship operations.
The Hyde GUARDIAN® BWMS was a pioneer in the effective use of ultraviolet (UV) light combined with a proprietary filtration system to deliver the flexibility needed to address varying types of water quality around the world. And, by enabling vessel operators to adjust the UV treatment dose, the Hyde GUARDIAN BWMS can operate at peak efficiency, so no organisms are left untreated, and no excess energy is consumed.
Ideal for flow rates up to 1000 m3/h, the Hyde GUARDIAN® BWMS offers the maritime industry’s first automated performance analytics solution for ballast water management – the Hyde GUARDIAN Data Log Analysis Utility (DLAU).
DLAU is a predictive maintenance tool, which monitors the health and performance of the entire Hyde GUARDIAN system. Data are shared with both the owner and De Nora technical specialists. Moreover, DLAU is part of a broader cloud-based technology suite – DE NORA VIA™ , which offers comprehensive remote support technology and enabling De Nora technical support specialists to remotely connect with crews in real-time to provide support services for optimal BWMS operations.
With an intuitive interface, easy integration with the existing automation systems, and a first-of-its-kind feedback alarm to tell crews when the system is not operating inside the boundaries of the Type Approval testing, the Hyde GUARDIAN BWMS is a leap forward in BWM performance and results.
The De Nora BALPURE ® BWMS delivers cost benefits specific to energy consumption – a crucial factor when selecting a ballast water management system for a vessel, such as an oil or chemical tanker.
With the BALPURE BWMS, shipowners and operators get the unique advantage of a smart EC technology designed to help better manage operational expenses (OPEX) by mitigating expenses related to energy consumption.
Additionally, the BALPURE BWMS utilizes slip-stream technology, which allows electrolysis equipment to be remotely mounted – independent of the ballast lines. All other components can be separated into smaller sub-assemblies for installation flexibility. The equipment can be located conveniently throughout the vessel and filters can be placed in hazardous zone-rated areas, ensuring the BALPURE BWMS can be used on oil and chemical tankers.
The slip-stream technology is important. It enables better control over the inputs into the electrochlorination equipment. This provides energy saving to the ship operator since the BWMS is never trying to create hypochlorite in substandard conditions. And, the dosing of hypochlorite can also be varied depending on how challenging the local water conditions are – enabling operators to comply with the most challenging waters, such as waters with low salinity or low temperature at the most optimum level.
Beyond ballast water management, De Nora helps maritime operators comply with IMO discharge standard for the treatment of offshore and marine sewage. Soon, De Nora will be launching its successor to the De Nora M55, a reliable workhorse of the industry. The new technology will once again will raise the standard by which all other sewage treatment plants will be measured by leveraging two unique technologies to help achieve compliance with new IMO requirements.
Bulk carriers often have higher flow rates on discharge than on uptake. This can be challenging for full flow EC and UV technology systems but with a slipstream system, the flow rate can vary without drastically affecting the size of the BWMS.
A repeat customer has chosen to install a BALPURE® BWMS capable of treating up to 3,000 m3/h on ballasting with the ballast pumps sized to 2 x 2,500 m3/h. The customer reviewed different sizes and configuration of BWMS but with the flexibility layout to support an after peak and stripping, the customer decided that a slipstream EC BWMS at lower treatment rated capacity best suited their needs.
The filter control valve is to manage the flowrate to ensure that the BWMS does not receive a higher TRC than it is able to treat. The BP-24 with self-cleaning electrodes was therefore fitted, designed to treat the 50% of the total ballasting flow rate on uptake, ensuring that the hypochlorite production capability does not decrease over time. On discharge, the system can neutralize 100% of the TRC if needed. Two neutralisation pumps were provided to support the neutralisation of two (2) dedicated stripping pumps and we worked with the customer to optimise our controls to ensure the lowest CAPEX for them.
