Ballast water management system

HK

Quality assurance system for boiler and water treatment systems and on-line maintenance service

Our head office and Hojo factory are sites with a registered environmental management system.

We want to protect this wonderful natural world and pass it on to the next generation.

At MIURA, we will cherish those wishes and use

the whole strength of the company to work towards our mission of

“Helping customers all over the world in energy conservation and environmental preservation.”

One major support for those e�orts is the ballast water management system (BWMS),

which contributes to the preservation of the marine environment around the world.

Our Ship Machinery Department has over ��y years of proven results

and experience and is playing a key role as we utilize our technology and the trust in

MIURA and put all our e�orts into the achievement of our aims.

Operation tests ongoing in preparation for USCG onboard test

MIURA aims to obtain USCG (United States Coast Guard) type approval during �scal 2017

and is currently advancing preparations for this. AMS (Alternate Management Systems)

approval has already been obtained and operation tests in preparation for onboard test are

currently in progress. Discussions on the various evaluation standards and interpretations have

been held with MERC (Maritime Environmental Resource Center), which is a certi�ed

Independent Laboratory (IL) test site designated by the USCG. �e equipment has been

installed on a test ship that has a route where it is possible to perform the test in “di�erent sea

areas,” as is required by the USCG, and status test is currently in progress. Furthermore, for the

live/dead judgment in the biological tests, MIURA is checking the judgment using a staining

method based on the USCG ETV protocol conditions for both sea water and fresh water

conditions in preparation for the acquisition of USCG type approval.

Schedule: January 2017: Start of USCG environmental test

March 2017: Start of USCG land-based test

April 2017: Start of USCG onboard test

MIURA activities for the acquisition of USCG type approvalFrom the start of the development work at MIURA, the objective was to obtain USCG type approval and the products were created to fully exhibit their performance in testing by an institution designated by the USCG. In 2014, approval as a ballast water management system was received from the Ministry of Land, Infrastructure, Transport and Tourism. A�er that, AMS approval was obtained in order to respond to the requirements of customers as quickly as possible. We are now building up proven results in installation for the various vessel types and sizes and working with the goal of obtaining USCG type approval during �scal 2017.

Ballast water management systems to maintain the marine ecosystemMiura BWMS is a clean type of system that combine a �lter and sterilization using UV light. One feature of the method of sterilization using UV light is that no active substances are used during the treatment, so there is no impact on the organisms where the treated ballast water is discharged.We developed a �lter for the management system that can reliably capture organism of 50 µm or larger and added a multi-stage cleaning function with high maintainability. �e medium pressure UV pipe used in the UV sterilization was newly developed to save electricity and extend the service life and the optimal sterilization performance was achieved by using the illumination intensity and the �ow rate to calculate and control the amount of irradiation.

�e obligation to install a ballast water management systemIt has been decided that the Ballast Water Management Convention will come into force on September 8, 2017. �is means that the installation of a “ballast water management system” will be required for all newly constructed vessels that are completed from September 2017 onwards. Furthermore, all vessels currently in service will be required to complete the installation before the renewal of their IOPP certi�cate, which will be between September 2017 and September 2022. MIURA has sold BWMS since 2014 and has built up a proven record of their installation on newly constructed vessels and their retro�tting on vessels already in service.

Environmentally friendly product creationMIURA aims to be the best partner of heat, water and the environment and has acquired ISO 14001 certi�cation from 2007. We are promoting environmental activities around the three pillars of the environmental contribution from our products, the consideration for the environment at our o�ces and factories, and our social contribution related to the environment. In our BWMS too, in addition to the environmental contribution from the products themselves, we also give consideration to environmental conservation during our manufacturing processes.

Environmentally friendly system with a uniquely developed �lter and UV reactor combination�e greatest feature of the Miura BWMS is its structure,

which uses a uniquely developed �lter to capture microorganism of 50 µm or larger from the ballast water

and then uses a UV reactor to irradiate the organisms with ultraviolet (UV) light to sterilize them.

It is an environmentally friendly system with no impact on the organisms where the treated ballast water is discharged,

because no active substances (chemicals) are used.

It can continue to exhibit its performance in each of the di�erent water qualities of sea water,

brackish water and fresh water.

Product Features

An original cleaning system to maintain the capture performance of the �lter

Reliable sterilization of organisms with a uniquely developed UV irradiation method

The three MIURA original cleaning patterns preserving the filter performanceIn order to reduce the clogging of the filter, a function is included that can clean the filter element in multiple stages. With these three cleaning patterns, high pressure jet cleaning is performed from the outside of the filter element to keep the filter clean at all times and preserve the filter performance.

Proportional control operation to realize reduced electricity consumption and longer service lifeThe short service life of UV lamp was previously the disadvan-tage of UV irradiation, but we have improved this with a method of operation that uses proportional control. A UV sensor monitors the UV illumination intensity and the amount of UV irradiation is controlled. This saves electricity and extends the service life.

MIURA has developed a �lter with an innovative structure that makes �lter cleaning possible at the same time as the capture of the organisms in the ballast water. With MIURA’s unique multi-stage cleaning function, the maintainability and performance are supported and the capturing function of the �lter is maintained. �e �lter is always maintained in a clean state, so it does not require the time and e�ort of the crew of the vessel and the primary duties in cargo handling can be performed smoothly.

MIURA started the installation of the independently developed BWMS from 2014. As we have accumulated proven results in the installation of the system, we have also received favorable evaluations of the sterilization performance for S-sized and smaller organisms and for fungi. We are implementing repeated improvements to reduce power consumption and extend the service life and are aiming for further quality improvements. A cleaning function has been included inside the UV reactor to reduce the maintenance work that the crew of the vessel must perform.

�e touch screen type control panel easily operated from the ship’s o�ce

Under the AMS defined by the USCG, it is necessary to obtain fresh water test data before permission for use in fresh water can be obtained. To achieve this, we con-structed a “fresh water test site” separate to our existing “sea water testing site” in 2015. This site is in Ehime Prefecture, which is where our head office is located. In preparation for the acquisition of USCG type approval during fiscal 2017, test is being repeated in both fresh water and sea water and we are continuing to work to improve the quality of the systems.

In-house developed products, support from maintenance to parts suppliesThe main parts were developed in-house at MIURA, so we provide support for everything from consumable parts to large-scale and functional components. We support the smooth operation of marine equipment with maintenance, preservation and management assistance that meets the needs of the customers.

Single engineer for all maintenance workMIURA engineers have the technical ability to be able to cover all the maintenance work related to marine equipment on their own, including electrical, mechanical and water management work. As an individual engineer performs the maintenance reliably, this makes rapid support possible and also contributes to a reduction in maintenance costs.

MIURA’s network across the worldIn addition to our bases in Japan, we also have engineers at our bases in Singapore, the Netherlands, Taiwan, China and America. We have prepared a system to respond to customer requirements rapidly at any location around the world. This ability to provide the best possible support in both providing parts supplies and engineering services is a distinctive characteristic of MIURA.
