A total of 22 bulk carriers, being built by Yangzhou Guoyu Shipbuilding Co. Ltd in China for Singapore based Pioneer Marine, will feature Wärtsilä Ballast Water Management Systems (BWMS). The Wärtsilä systems will enable the vessels to comply fully with the IMO’s ballast water convention. The contracts were finalised in August.
Each of the 38,000 DWT vessels will be fitted with two Wärtsilä AQUARIUS UV BWMS, and the scope of supply includes also the commissioning and sea trials of the equipment. The contracts thus involve a total of 44 Wärtsilä BWMS units, which represents the biggest ever single owner order to date for any BWMS manufacturer. It is expected that all 44 systems will be delivered before the end of 2015, with the first delivery scheduled for December 2014.
The Wärtsilä Aquarius UV is one of only four systems tested and approved for fresh water operation under the United States Coast Guard’s AMS (Alternative Management System) criteria. This approval was cited as being an important factor in Pioneer Marine’s decision process when selecting a BWMS supplier.
Whilst the IMO’s Ballast Water Management Convention, which will require the owners of up to 40,000 vessels worldwide to install a ballast water management system (BWMS), is still to be ratified, the US Coast Guard (USCG) has already implemented its own legislation. This states that all ships will have to be in compliance with the regulations 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 can harm local species. Wärtsilä’s AQUARIUS UV systems have been type approved for the IMO regulations.
“When looking for a ballast water treatment manufacturer, we wanted to partner with a company having a global presence and a recognized brand to support their products. It was critical that whomever we chose had a proven history in supporting their products. This is particularly relevant when looking at this piece of equipment as no one yet has USCG type approval, and we felt that with the weight of Wärtsilä behind it this will ensure our equipment complies within the time frame allotted”, says Stuart Crawford, Senior Vice President, Head of Technical, Pioneer Marine Advisers Pte Ltd.
“We experienced a very proactive approach from the project manager during discussions, which eventually led to our choice of manufacturer”, he continues.
“Our shipyard has built a long-term relationship with Wärtsilä that dates back to the first vessel we exported, which used a Wärtsilä main engine. Wärtsilä’s merger with Hamworthy gave access to their Ballast Water Treatment solutions, and we are confident that after technical investigation this equipment will comply with the most stringent regulations. Even though it is a new product promoted by Wärtsilä, considering our long and good relationship with them, we know the company to be a reliable and trustful supplier, and that they will give strong support to the yard. We are sure Wärtsilä and Guoyu Group will have a good and smooth co-operation for this new product and extend the co-operation to a comprehensive platform,” says Annie Dai, Marketing Manager, Guoyu Shipyard.
“This is an important order and is indicative of the growing need for ballast water discharging to be properly managed. These vessels will operate in and around US waters, and it was imperative that the selected BWMS have the appropriate approvals. Wärtsilä has a strong track record in this field, and the components used have been used and thoroughly tested in the marine environment for many years,” says Dr Joe Thomas, Director, Wärtsilä Ballast Water Management Systems.
The bulk carriers are based on the Green Dolphin design, a concept that meets current and anticipated air and water emission regulations.
The Wärtsilä AQUARIUS UV BWMS
The Wärtsilä AQUARIUS® UV BWMS uses a simple two stage process involving filtration and UV irradiation. During uptake, seawater is first passed through a 40 micron backwashing screen to remove particulate, sediment, zooplankton and phytoplankton. Disinfection of the filtered sea water is then carried out using medium pressure UV lamps, and controlled by the BWMS control system. Upon discharge, the filter is by-passed but the ballast water is again disinfected with UV treatment before safe discharge back into the sea. There are 13 distinct Wärtsilä AQUARIUS® UV BWMS standard modules available with capacities ranging from 50 m3/h to 1000 m3/h.
