Six new bulk carriers, being built at the Namura and Onomichi shipyards in Japan, are to be fitted with 12 Wärtsilä Aquarius UV ballast water management systems (BWMS). The Wärtsilä systems will enable the vessels to comply with anticipated International Maritime Organization (IMO) regulations. The contracts were signed in October.
Japan has recently ratified the IMO’s Ballast Water Management Convention, and these orders are the first for Aquarius UV systems for newbuild vessels from a Japanese shipyard. The Namura yard will install two BWMS units with a capacity of up to 500 m3 of ballast water per hour to each of two 34,000 DWT carriers. The Onomichi yard is building four 60,000 DWT carriers, each of which will be fitted with two Aquarius UV systems having a capacity of up to 1000 m3 per hour. Deliveries from Wärtsilä will commence at the end of 2014 and will be completed by mid 2016.
“This significant order shows once again that efficient ballast water management is becoming a priority for owners and operators around the world. We are grateful to our brokers in Japan, Harison Sangyo Co., Ltd. for their valuable assistance in finalizing this contract,” says Mr Joe Thomas, Ballast Water Treatment Director, Wärtsilä Ship Power.
The IMO ratification requires support from 35% of the world’s merchant shipping tonnage. Japan and Turkey recently ratified the ballast water convention, meaning that contracting countries now represent 32.54%, just 2.5% short of the necessary tonnage. Ratification is, therefore, expected within the near future.
When ratified, the IMO’s Ballast Water Management Convention will require the owners of up to 40,000 vessels worldwide to install a BWMS. However, the US Coast Guard (USCG) has already implemented legislation requiring compliance with the regulations covering discharges from ships when sailing in US coastal waters. The intention of the legislation is to address the issue of invasive aquatic species being carried in the ballast water of ships and then discharged to the sea where they could possibly harm local species.
Wärtsilä Aquarius UV
The Wärtsilä Aquarius UV BWMS is a modular system utilising a two stage approach involving filtration and medium pressure UV disinfection technology. The system meets the IMO D2 discharge standard, and has been awarded classification society type approval.
