BALLAST WATER MANAGEMENT
THE RIGHT BWMS FOR EACH SHIP

Ballast Water Management Systems

Invasive species devastating the marine environment: we find dramatic examples all around the world! Unfortunately, ballasting and deballasting practices of the past have contributed to this. At Wärtsilä Water & Waste we believe that the most effective way to stop the spread of ballast water invasive species is to prevent their introduction.

To accomplish this, our team of engineers has developed two lines of Acquarius® Ballast Water Management Systems (BWMS). These enable our customers to meet their global ballast water discharge regulatory obligations. Both technical solutions, one based on filter UV and the other on filter side stream electro-chlorination (EC), have achieved IMO, UGA and USCG (type) approvals. Both technologies hold several class and hazardous area ATEX approvals and guarantee maximum flexibility and choice to our customer.

Wärtsilä Aquarius UV Ballast Water Management System chosen for retrofitting to four Korean vessels

by Wärtsilä Corporation | Sep 13, 2019

The technology group Wärtsilä will supply its Aquarius UV Ballast Water Management System (BWMS) for four bunkering ocean tanker vessels operated by South Korea’s Doorae Shipping. This is the first ever BWMS retrofit contract signed by Wärtsilä in Korea. The order was placed in July by PanStar TechSolution, the main contractor for the project. PanStar TechSolution is a leading Korean engineering and technical company specialising in BWMS and exhaust gas cleaning system (EGCS) retrofit projects. 

The retrofitting will allow the vessels to be in compliance with the International Maritime Organization’s (IMO) Ballast Water Management Convention, which is applicable to existing vessels by their next special survey after September 2019. The regulation aims at preventing the spread of harmful aquatic organisms from one region to another, and halting damage to the marine environment from ballast water discharge.

“The design of the Wärtsilä BWMS solutions provides maximum flexibility during system design and installation. Key components are positioned to suit available space, which is a major advantage in retrofit projects such as this. We already work closely with Doorae Shipping because of the maintenance agreement we have with them, and we are very pleased to have been selected against tough competition to supply the BWMS solutions,” says Woo Ho Yoo, General Manager, Services, Wärtsilä Korea.

“We have had good experience with the service provided by Wärtsilä, and we appreciate the reliable support that they have given us. The Aquarius UV BWMS has excellent references and is the right choice for us,” says Hyung-Jung Cheon, President & CEO, Doorae shipping Co., Ltd.

The Wärtsilä equipment is scheduled for delivery commencing in August 2020. Wärtsilä currently maintains and services the engines of six ships in the Doorae fleet under a five-year agreement signed in November 2017.

The Wärtsilä Aquarius UV BWMS is based on a two-stage treatment process using proven and validated system components. Upon uptake, seawater is first passed through a back washing screen type filter. The filtered seawater then passes through a UV chamber where ultra-violet light is used to disinfect the water before entering the ballast tank. On discharge, water from the ballast tank is pumped through the UV chamber for a second time to complete the disinfection process prior to discharge.

The system has been granted US Coastguard (USCG) Type Approval. With the company’s other BWMS technology, the Wärtsilä Aquarius EC, already Type Approved by USCG, Wärtsilä is the first manufacturer able to offer two USCG Type Approved BWMS technologies. The Wärtsilä Aquarius EC (Electro-Chlorination) system features a simple two-stage process involving filtration and electro-chlorination across the full scope of a ship’s operating and environmental conditions. In addition to the USCG approvals, both technologies have also been awarded Type Approval by the International Maritime Organization (IMO).

Required by IMO

The International Maritime Organisation (IMO) introduced in 2004 the Ballast Water Code (BWC) to address the Control and Management of Ships’ Ballast Water and Sediments for all sea going ships greater than 400 gt using ballast water. The Ballast Water Management Convention (BWMC) entered into force 8 September 2017. Ships are required to manage their ballast tanks to remove or render harmless the ballast water discharge of invasive species.

Our experience and in-depth knowledge about vessels and marine engineering allow us to have a optimal understanding of the environment in which a Ballast Water Management System is going to be installed. With our technical assessment of BWMS for your specific vessel, we are capable of showing potential equipment locations, installation paths, electrical cabinet locations. Our team of engineers can also make recommendations for what should be considered during installation.

We realize that equipment operations are essential and that problems and down-time have an effect on the owners bottom line. We believe that a single supplier for the entire design process, equipment supply and installation support is beneficial to the ship owner, both in terms of cost and efficiency. Communication across different disciplines is proven more efficient when exchanged within the same company.
