Choosing a Ballast Water Management System (BWMS) has never been more crucial, particularly for today’s oil and chemical tanker market. Global economic and supply chain headwinds on land and sea continue to reshape the fundamental way raw material makes its way to the manufacturing floor. Ballast water equipment manufacturers are not immune to these dynamics. With proper planning, the De Nora team can work alongside shipowners and operators to ensure selection, design application, installation and commissioning of a BWMS is as easy as possible.
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 an 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 International Maritime Organization (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.
The customer previously used and had operational and support issues with a number of different BWMS. They were primarily focused on finding a reliable BWMS and BWMS company who would act as a partner to support the installations and service the system. Low power consumption, redundancy concepts and flexibility on installation and operation were their main drivers.
Although De Nora could have provided one system with a TRC of 6,000 m3/h to treat 2 of the 3 ballast pumps rated at 3000m3/h each, the customer preferred to use two system as they had a control system dedicated to port and starboard. They also followed this configuration to ensure a cross-over ability in the event that there was an issue with either system.
Two BALPURE® BP3000-A systems were successfully installed per vessel, in line with the customer requirements. All operational scenarios on ballasting, de-ballasting and stripping satisfied. Engineering, installation and commissioning was supported by De Nora. De Nora also delivered specific training to the customer to ensure that albeit crew changing, they were able to continue to operate and maintain the systems well into the future.
