– Japan’s First Approval from ClassNK –

TOKYO—Mitsui O.S.K. Lines, Ltd. (MOL;  President: Koichi Muto) today announced that the company acquired approval in  concept for installation of a packaged container ballast water treatment system  that can fit in a vessel’s cargo hold(*). This is a joint technological  development with Mitsubishi Heavy Industries, Ltd. (MHI; President Hideaki  Omiya) and marks Japan’s first approval of such a  system by Nippon Kaiji Kyokai (ClassNK). The new technology offers much faster  installation time on an existing vessel, compared to systems installed in the  vessel’s engine room.

Commercially  available BWTS is packaged in a 40-foot container (about 12m long) with electric  equipment. Ease of maintenance and accessibility is considered for this  containerized design.

[Characteristics of the  container-type ballast water treatment system]

(1)     Shorten  the work required such for preliminary inspection because the system is  containerized, allowing for a great reduction of detailed pipe fitting and  adjustment at the installation stage.

(2)     Installation time is reduced by an  estimated seven days, compared to installing a system in the engine room.

(3)     Effective  solution for vessels with limited engine room space.

MOL and MHI started  detailed engineering work and will install an experimental system with a  capacity of 750m3/h (the first ever to fit in a 40-foot container) on  the MOL-owned 8, 100 TEU containership MOL  Competence this spring.

Ballast water  discharged while loading/discharging cargo carries marine organisms around the  world and can have a negative impact on marine ecosystems and biodiversity. This  has become a subject of global concern since the late 1980s. Accordingly, the  International Maritime Organization (IMO) adopted the Ballast Water Management  Convention in February 2004, and its ratification is under  way.

Our customers are  managing their own global footprint and this new system highlights how MOL is  staying at the forefront of eco-management advancements. The project to install  the system on the containership is part of MOL’s approach to “contribution to  conservation of biodiversity, ” which is one of the company’s environmental  strategic targets in the midterm management plan GEAR UP! MOL. MOL continually  forges ahead to offer transport solutions that put less of a burden on the  global and marine environments. MOL is also preparing to ensure compliance with  to the Ballast Water Management Convention by accumulating experience in system  installation and operation.
