Alfa Laval’s PureBallast Treats Tankers

PureBallast, Alfa Laval’s chemical-free system for ballast water treatment developed in cooperation with Wallenius Water, will be installed aboard two new bitumen tankers for Nynas, a supplier of specialty petroleum products. It is the first ballast water treatment installation adapted to the hazardous tanker environment. Nynas, a specialist in naphthenic oils and one of Europe’s leading suppliers of bitumen, has chosen PureBallast for two bitumen tankers to be built at China’s Wuhan Nanhua Huanggang Jiangbei Shipyard. Scheduled for delivery in 2010, the Nynas vessels will each have a ballast tank capacity of 2150 m3 and a treatment system flow of 500 m3/h. But in light of their cargo and the resulting gas risks on board, the vessels will have their PureBallast systems above deck rather than below. The ballast water treatment solution, which involves a specially designed enclosure, is the first to be certified for use aboard petroleum tankers. Even after Nynas had chosen PureBallast, the system had to be adapted to the hazardous environment of a bitumen tanker. As well as releasing gases, bitumen is normally transported at a temperature between 160-180ºC but vessels can carry products up to a temperature of 250ºC. Such conditions have thus far prevented ballast water treatment on tankers, since no ballast water treatment system has yet been classified as EX-proof.

CleanBallast Approved by USCG

As one of the first ballast water treatment systems, RWO’s CleanBallast has received the AMS approval .   This certificate is awarded by the United States Coast Guard (USCG) and is considered to be the crucial supporting requirement for future purchasing decisions of shipowners and yards.   The AMS approval is just the latest success in a series of achievements RWO accomplished in the past months

DESMI Containerized BWTS Tested by Maersk

DESMI Ocean Guard’s containerised BWTS solution successfully 
tested by A.P. Moller - Maersk. The OxyClean system based on UV and ozone has come through testing in both fresh, brackish and salt water, and Maersk Line concluded it to be an attractive solution, in particular for container ship retrofits. Per Hother Rasmussen from Maersk Maritime Technology explains: ”We have tested containerized ballast water treatment system plants on two different vessels and we find it a viable

Mariner Omnipure M55 Selected for Australian Patrol Boats

The Mariner Omnipure sewage treatment system from Severn Trent De Nora has been installed on Cape St George, a new patrol boat designed and constructed by Austal for the Australian Customs and Border Protection Service. Cape St George is the first in a series of eight patrol boats to be delivered to the owners between March 2013 and February 2015, which will all be outfitted with the Mariner Omnipure M5508 system. The contract was secured through HMA-POGC of Australia.  

California: BW Treatment Research

  The California State Lands Commission (CSLC) will conduct a business meeting in Sacramento on March 25.  Among the items on the calendar is a request for authority to enter into a contract to support vessel modifications and conduct shipboard ballast water treatment research.  The plan calls for the CSLC to contribute $100,000 toward a $700,000 effort to install an experimental ballast water treatment system on the California Maritime Academy (CMA) training ship GOLDEN BEAR

Omnipure Series 55 Receives USCG Certification

Omnipure Series 55 marine sanitation treatment systems from Severn Trent De Nora have received final certification from the United States Coast Guard (USCG) to the International Maritime Organization’s MEPC.159(55) effluent standards. Certification by the USCG involves testing environmental standards such as shock and vibration above and beyond IMO requirements. The Omnipure Series 55 technology utilizes a unique electrolytic treatment process

Severn Trent De Nora’s BALPURE Completes Shipboard Testing

Non-indigenous species were no match for the BALPURE electrolytic disinfection ballast water treatment system. The BALPURE®ballast water treatment system from Severn Trent De Nora successfully completed shipboard testing in December 2010, effectively neutralizing non-indigenous species. The BALPURE system surpasses requirements for IMO G8 Type Approval and IMO Ballast Water Convention D-2 Standards. Type approval of theBALPURE system is anticipated in the first half of 2011.

Lloyd’s Register Releases Guide on Ballast Water Treatment

Lloyd’s Register has released a new Guide to Ballast Water Treatment Technology that provides an independent and impartial description and appraisal of commercially available and developing technologies for ballast water treatment. It is the result of work conducted by the internationally respected Center for Water Science at Cranfield University, UK on behalf of Lloyd’s Register. The treatment of ballast water is one of the most significant environmental and operational challenges

Hansa Shipping Equips Four New Vessels With CleanBallast®

Bremen – After careful comparison and in-depth analysis, German owner Hansa Shipping and Chinese shipyard Jiangsu New Yangzi Shipbuilding have decided to equip four new 4,800 TEU vessels with the German ballast water treatment technology CleanBallast® by RWO, a subsidiary of Veolia Water Solutions & Technologies. The plants will be delivered during the course of 2012. “We have picked RWO knowing that we are dealing with a sensitive and important task for the Future

BWTS Fitting on Japanese VLCC a First

Mitsui O.S.K. Lines, Ltd. (MOL) plan to install a ballast water treatment system on an in-service very large crude oil carrier (VLCC). This will be the first such onboard system installed by any Japanese shipowner on an existing VLCC. The company chose the JFE Ballast Ace system developed by JFE Engineering Corporation. The installation will take place while the vessel is docked from March through April. Ballast water discharged while loading/discharging cargo carries marine organisms
