FAQ

Why Filter + Formulated Chemical Injection?

There are various methods for treating ballast water, such as formulated chemical injection, seawater electrolysis, ultraviolet rays, and deoxygenation by nitrogen. Since our development of the JFE BallastAce® system, we have striven to ensure high compatibility with a range of ships, cooperating with shipping companies from the very beginning. In employing a combined treatment method using filters and formulated chemicals, we’ve created a system that can balance a high level of treatment performance with a minimization of environmental impacts, and which can be mounted onboard even ships with numerous restrictions, such as limited installation space and electric power capacity. The features of the treatment performance are to (1) filter out as many organisms as possible and return them to the original habitat area with the backwash function, (2) treat the ballast water with a minimal amount of disinfectant, and (3) reduce the residual oxidants with neutralizer before discharging the treated ballast water.

Does the system have any effects on the paint of the ballast water tank?

The system has been type approved by IMO after a series of successful results of corrosion tests run according to the IMO guidelines.
The IPPIC (the International Paint and Printing Ink Council) formally stated in IMO MEPC63 that there should be no significant effects with up to an 8ppm concentration of active substances. In addition, Chugoku Marine Paints, Ltd. declared that such concentration is deem acceptable through 15 years of use.

How do you decide the optimum treatment capacity of the BWMS for my ship?

Let us know your vessel’s required ballasting and de-ballasting capacity. The rated capacity of JFE BallastAce should be equal to the sterilizing treatment capacity during ballasting. In most cases, the ballast pump rated capacity is adapted to the capacity of the BWMS; however, you may also choose a smaller capacity than the rated ballast pump capacity when the ship does not require the full ballast capacity, as when operating, for example, a large bulk carrier. On the other hand, the neutralizing treatment capacity during de-ballasting can also be set up to be larger than the ballast pump rated capacity, considering the gravity deballasting operation.

What if the equipped system has not been used for a long period of time? Could it be evaluated in advance of the compliance date of the ship?

We offer recommissioning services, which include a package of maintenance work and functional evaluations to ensure that your vessel is in full compliance with current regulations, while also providing training services to the staff of your vessel at the same time. If you feel unsure as to whether your system complies with regulations, please contact our Technical Service Site.

I want to request training for vessel staff.

A one day training session onboard the vessel during the commissioning period of the BWMS installation is provided for free as a part of our standard operations. Upon the customer’s request, we offer training programs at at our Training Center in Yokohama, Japan and can also provide training onboard by dispatching one of our engineers to your vessel. Please contact our Technical Service Site for a quotation request.
