Wärtsilä has secured a contract from Italy’s Carbofin, part of the Carboflotta group, to install its Aquarius UV ballast water management system (BWMS) on liquefied petroleum gas (LPG) vessel ‘Marola’.
Retrofitting work on the 37,000m³ Marola will be carried begin in the third quarter of 2013 when the vessel is dry docked.
The Wärtsilä Aquarius UV BMWS, which can be tailored to meet specific requirements, is intended to help owners and operators reduce their environmental footprint.
The Aquarius UV BWMS is based on a two-stage treatment process under which seawater is first passed through a back washing screen filter, then through a UV chamber that disinfects the water before entering the ballast tank.
After discharge, the water is sent through the UV chamber for a second time to complete the disinfection process.
Under the project, Wärtsilä will also provide engineering support, commissioning and start up for the Marola, which will operate in the US Gulf of Mexico, the Caribbean and South American waters.
Carboflotta technical manager Roberto Saia said the company aims to improve its own environmental performance as well as reduce marine pollution by minimising the risk of emissions and harmful releases.
"By retrofitting Wärtsilä’s AQUARIUS ballast water management system to the ‘Marola’, we can be assured of conforming to legislation, as well as protecting and safeguarding the environment in sensitive areas around the world," Saia said.
Wärtsilä said the system meets the International Maritime Organization (IMO) D2 discharge standard and received type approval in December 2012.
