MOL to Install Ballast Water Treatment System on VLCC

Associated services in the market Wärtsilä has an agreement with Canada-based Trojan Technologies to offer the Marinex ballast water management system (BWMS), alongside the Wärtsilä Hamworthy AQUARIUS(TM) range, which was introduced to the market last year. Wärtsilä now offers the widest range of BWMS and associated services in the market."We recognise that no one solution will be suitable across all ship types, sizes and environmental conditions," says Dr Joe Thomas, Director, Ballast Water Systems, Wärtsilä Environmental Solutions. "By having both the AQUARIUS(TM) and Marinex systems available, Wärtsilä is uniquely placed to deliver BWMS that meet the specific requirements of individual owners and their vessels."In 2010, Wärtsilä Corporation and Trojan Technologies signed an exclusive agreement to jointly develop, market and distribute a BWMS for the marine market. During the past two years the companies have worked together on a new ultra-violet (UV) technology-based system and the collaboration has made good progress.Ship board trials are expected to be completed in September of this year along with Environmental Technology Verification (ETV) land-based testing which will be in line with US validation requirements.Wärtsilä acquired the Hamworthy AQUARIUS(TM) UV and electro chlorination (EC) BWMS as part of the acquisition of Hamworthy plc in January 2012. ...

Asuka II to receive the Ecomarine system Japanese companies Sumitomo Electric Industries and NYK Cruises have agreed to install a Sumitomo 'Ecomarine' ultraviolet ballast water management (BWM) system on one of NYK's cruise ships.Asuka II will receive the Ecomarine system in January 2012, and it will undertake demonstration testing of the system, which is under development by Sumitomo Electric. The two companies will cooperate in onboard testing specified by the International Convention for the Control and Management of Ships' Ballast Water and Sediments.Ecomarine incorporates filter units originally developed by Sumitomo Electric to separate large plankton and other aquatic organisms. The ballast water management system then eliminates any remaining small organisms with a medium-pressure ultraviolet system. The system has been designed to save power, while providing reliable removal of organisms. It is claimed to offer environmental benefits in comparison to other chemical-free ultraviolet BWM systems. The simple combination of filter units and compact, high-powered,medium-pressure UV system is said to offer ease of use and low maintenance.Sumitomo says that when tested on land using a setup comparable to actual use conditions (water treatment at 200 m3/h), Ecomarine demonstrated power consumption reduction and high organism removal capacity, as intended. The company has applied ...

From January 1, 2012, all ships should exchange ballast water With effect from January 1, 2012, all ships should exchange ballast water before entering the Mediterranean Sea or after leaving the Mediterranean Sea to meet the regulation D-1 standard of the Ballast Water Convention. Exchange should be carried out at least 200 nautical miles from land and in waters at least 200 metres deep. The sequential, flow through or dilution methods of ballast water exchange are accepted as meeting the D-1 standard.In situations where this is not possible (because the ship will have to deviate from its intended voyage; because exchange will delay the ship; or for safety reasons) exchange should be undertaken before entering the Mediterranean Sea area, or after leaving the Mediterranean Sea area, as far from the nearest land as possible, and in all cases in waters at least 50 nautical miles from the nearest land and at least 200 metres deep.When engaged in traffic between the ports and areas listed below, ships should undertake ballast water exchange in waters at least 50 nautical miles from the nearest land and at least 200 metres deep or in an area designated by a port State:1. ports located within ...
