ClassNK has released amendments to its Guidelines on the Installation of Ballast Water Treatment Systems. These include changes to the ballast water performance standard application date (based on the revised implementation schedule adopted by the International Maritime Organization), as well as changes and additions of definitions, and a revision of standards for the installation of ballast water treatment system.

The first edition of the guidelines was released in 2010, and contained information regarding the selection of ballast water treatment systems, as well general requirements and precautions related to installation. It also included a description of the ClassNK’s approval process for ballast water treatment systems.

The International Convention for the Control and Management of Ships’ Ballast Water and Sediments, 2004 (BWM Convention) was adopted by the International Maritime Organization (IMO), with the intention of protecting the marine environment from harmful aquatic organisms’ transfer in ballast water carried by vessels.

The latest guidelines also include more information on requirements relating to standards for the installation of ballast water treatment systems. This is in response to the IACS Unified Requirement (UR) M74 Installation of Ballast Water Management Systems, which was adopted in September 2015. Additional requirements for tankers that carry flammable liquids have been laid out in the guidelines.
