Introduction

1 The Committee, at its fifty-ninth session, agreed to conduct a new review of the status of ballast water technologies before the 2012 application date, or before the entry into force of the Convention, and to re-establish the Ballast Water Review Group (BWRG) during MEPC 61 for this purpose, as well as to examine the applicable requirements for vessels described in regulation B-3.1 and any other aspects of ballast water management addressed in the annex to the Convention in accordance with the provisions contained in regulation D-5.1 (MEPC 59/24, paragraph 2.49).

2 This document, taking into account the outcome of MEPC 59, provides basic information on the estimated number of vessels to which regulation D-2 may apply. In particular, this document focuses on the applicable requirements for vessels described in regulation B-3.1.MEPC 61/2/17 Page 2

I:\MEPC\61\2-17.doc Provisions of regulation B-3.1

3 Regulation B-3.1 of the BWM Convention requires a vessel constructed before 2009, as follows:

" Regulation B-3 Ballast Water Management for vessels

1 A vessel constructed before 2009:

.1 with a Ballast Water Capacity of between 1,500 and 5,000 cubic metres, inclusive, shall conduct Ballast Water Management that at least meets the standard described in regulation D-1 or regulation D-2 until 2014, after which time it shall at least meet the standard described in regulation D-2;

.2 with a Ballast Water Capacity of less than 1,500 or greater than 5,000 cubic metres shall conduct Ballast Water Management that at least meets the standard described in regulation D-1 or regulation D-2 until 2016, after which time it shall at least meet the standard described in regulation D-2.

2 A vessel to which paragraph 1 applies shall comply with paragraph 1 not later than the first intermediate or renewal survey, whichever occurs first, after the anniversary date of delivery of the vessel in the year of compliance with the standard applicable to the vessel."

4 A vessel constructed before 2009 with ballast water capacity of between 1,500 and 5,000 cubic metres and with a capacity less than 1,500 or greater than 5,000 cubic metres will have to install the ballast water management system (BWMS)

not later than the first intermediate or renewal survey after the anniversary date of delivery of the vessel in 2015 and 2017, respectively.

Status of ballast water technologies

5 The number of available BWMS has been increasing. According to the third Lloyd's Register guide to "Ballast water treatment technology 1 ", nine BWMSs have been approved by Administration in accordance with Guidelines (G8), and Japan has approved

another two BWMSs 2 . In addition, in accordance with Procedure (G9), the Committee is invited to consider whether to grant Final Approval to seven BWMSs at this session. Since a lot of manufacturers have been developing BWMS, it is envisaged that the number of

available BWMS will further increase. It can be said that the status of ballast water technologies has been improving.

Number of vessels constructed before 2009

6 Although the number of available BWMS has increased significantly, it should be considered carefully whether all vessels constructed before 2009 will be able to comply with regulation B-3.1.

2 Japan approved the "Clear Ballast" BWMS developed by Hitachi Plant Technologies, Ltd. (5 March 2010) and the "JFE Ballast Ace" BWMS developed by JFE Engineering Corporation (26 May 2010).MEPC 61/2/17 Page 3

I:\MEPC\61\2-17.doc 7 Japan calculated the number of vessels to which regulation D-2 will apply

from 2009 to 2020. The method of calculation is shown at the annex. Table 1 shows that the number of vessels, subject to regulations B-3.1.1 and B-3.1.2, would be in total approximately 34,000 vessels and the number of vessels, which are required to retrofit BWMS is estimated at: 500 vessels in 2015 and 2016; 11,000 vessels in 2017; and 9,000 vessels in 2018 and 2019.

8 As shown in Figure 1, the number of vessels required to install BWMS is expected to rapidly increase in 2015 and sharply drop in 2020, because the vessels constructed
before 2009 shall install BWMS between 2015 and 2019.

I:\MEPC\61\2-17.doc Technical evaluation for installation of BWMS to an existing vessel

9 With regard to an individual existing vessel, a technical evaluation on the installation of BWMS would be necessary for each ship. In general, in the case of existing vessels, there are high possibilities to face difficulties for installation of BWMS, due to the complexity of piping arrangement, lack of extra space in engine-rooms and additional power of auxiliary engines that is necessary to run BWMS. In particular, the following technical issues should be considered depending on the characteristics of BWMSs:

.1 in case of a system using UV, it would be necessary to enlarge generator capacity or to add a generator to cover the increase of electricity consumption;

.2 in case of a system using filters, it would be necessary to increase the output pressure of pumps to compensate for the increased resistance by the filter, which would result in the increase of electricity consumption; and

.3 in case of a system using Active Substances, where such substances are to be supplied from the outside of a vessel, the position and structure of the storage tanks for the Active Substances as well as the piping requirement would have to be carefully considered to ensure the safety on board, bearing in mind that the Active Substances are chemical substances. This may limit the possible arrangement of BWMS.

10 It is envisaged that a lot of existing vessels, subject to regulations B-3.1.1 and B-3.1.2, will install BWMSs at docking perio d for survey. Although a necessary period for installation of BWMS depends on the characteristics of each vessel and the BWMS, it should

be noted that the above-mentioned technical issues would cause the extension of the docking period.

ESTIMATION METHODS OF THE NUMBER OF VESSELS TO WHICH REGULATION D-2

WILL APPLY

Common assumption

- Estimation on the number of vessels has been carried out for those vessels of 400 gross tonnage and above, taking into account that the survey requirements under the BWMS Convention apply to those vessels of 400 gross tonnage and above.

The number of vessels constructed in or after 2009 with a ballast water capacity of less than 5,000 cubic metres is estimated assuming that:

- vessels with ballast water capacity of less than 5,000 cubic metres are those of less than 10,000 gross tonnage; and

- the number of vessels to be construct ed every year after 2010 will be constant, and the same as the number of vessels delivered in 2009 based on "Lloyd's Register-Fairplay 2010 Ship Database" (hereinafter referred to as "LRFP data").

2 Regulation B-3.5

The number of vessels constructed in or after 2012 with a ballast water capacity of 5,000 cubic metres or more is estimated assuming that:

- vessels with ballast water capacity of 5,000 cubic metres or more are those of 10,000 gross tonnage or more; and

- the number of vessels to be constructed every year in or after 2012 will be constant, and the same as the number of vessels delivered in 2009 based on

"LRFP data".

3 Regulation B-3.1.1

The number of vessels constructed before 2009 with a Ballast Water Capacity of between 1,500 and 5,000 cubic metres is estimated assuming that:

- vessels with ballast water capacity of between 1,500 and 5,000 are those of between 3,000 and 10,000 gross tonnage;

- regulation D-2 applies to a third of the existing vessels for three years because existing vessels shall comply with the regulation D-2 not later than the first intermediate or renewal survey, whichever occurs first; and

- vessels are replaced at the age of 25; the number of those vessels that will be subject to D-2 in year 2015 could be estimated by using the number of the

vessels which were delivered between 1990 and 2009 based on LRFP data.MEPC 61/2/17 Annex, page 2

I:\MEPC\61\2-17.doc 4 Regulation B-3.1

vessels which were delivered between 1992 and 2009 based on LRFP data.

5 Regulation B-3.4

The number of vessels constructed in or after 2009, but before 2012, with a ballast water capacity of 5,000 cubic metres or more is estimated assuming that:

and

- the number of vessels constructed in or after 2009, but before 2012 will be constant, and the same as the number of vessels constructed in 2009 based on

"LRFP data".
