Lloyd's Register, on behalf of the Danish Authorities, has reviewed the technical documentation, test plans and reports throughout the type approval process. Surveys of factory acceptance tests, the test facilities and the test ship have also been performed by Lloyd's Register/DHI Denmark on behalf of the Danish Authorities.

MEPC 75/INF.12


3 As a conclusion to this process, the Danish Authorities find that the Bawat BWMS Mk2 satisfies the requirements of the new Code for Approval of Ballast Water Management Systems (BWMS Code), adopted by resolution MEPC.300(72), on the basis of testing, reported results and verification as adhered to within the 2016 Guidelines for approval of ballast water management systems (G8) adopted by resolution MEPC.279(70), and latest type approval relevant BWM.2 circulars. 4 In accordance with resolution MEPC.228(65) on Information reporting on type approved ballast water management systems, the following information is provided:

.1 approval date: 31 October 2019;

.2 name of the Danish Authorities: DEPA and DMA;

.3 name of the BWMS: Bawat BWMS Mk2;

.4 a copy of the type approval certificate can be found in the annex to this document;

.5 results from land-based and shipboard testing (summarized in the annex).

Description of the BWMS 5 The Bawat BWMS Mk2 employs pasteurization as the treatment process. The process involves heating the ballast water to be treated to a given pasteurization temperature (TPAST) and maintaining this temperature for a given minimum residence time (tRT). In the BWMS' Pasteurizing Unit the temperature of the ballast water is raised to a minimum treatment temperature of 64°C. Depending on the treatment temperature applied, the ballast water is kept at this elevated temperature for minimum residence times according to the following expressions:

• 64 °C ≤ TPAST < 72 °C: tRT ≥ -5 × TPAST + 400 s

• TPAST ≥ 72 °C: tRT ≥ 40 s

6 On-board Bawat BWMS Mk2 installations are exploiting ship surplus heat sources (e.g. main engine jacket cooling water, economizer or scavenge air) for the treatment process. The system is designed and integrated specifically for each ship on an assessment of excess heat available for ballast water treatment, layout of the heating system, amount of water to be ballasted/deballasted during cargo operations, number of ballast water tanks, trade pattern, etc. 7 The Bawat BWMS Mk2 main operational procedure is treatment in-voyage and not in operation during port stays. Therefore, the Treatment Rated Capacity (TRC) is not linked to the capacity of the ship's ballast water pumps, and for this reason the Bawat BWMS Mk2 is not dependent on the ship's ballast pump capacity for treatment operations. 8 The Bawat BWMS Mk2 design also qualified to be in accordance with Lloyd's Register Rules for Ships. Overview of the Bawat BWMS Mk2 type approval process 9 Based on review of documentation required in paragraphs 1.3 and 1.4 of the annex to the 2016 Guidelines (G8), inspections of the control and monitoring system during functional

MEPC 75/INF.12


tests, installations at the test site including a verifying Site Acceptance Test and witnessing of commissioning test cycles, Lloyd's Register qualified the system design to be in accordance with paragraph 4 of the 2016 Guidelines (G8) and paragraph 5 of the annex. The test set-up was verified to be in accordance with paragraphs 1.5 to 1.13 of the annex to the 2016 Guidelines (G8). 10 Land-based testing for the Bawat BWMS Mk2 was conducted independently by DHI Denmark in the period from 2 October to 13 December 2017. The BWMS was operated by DHI during testing. 11 The Bawat BWMS Mk2 was tested according to the manufacturer's performance claims, as applied within five consecutive successful test cycles in all (three) salinities and with challenge water characteristics as defined in paragraph 2 of the annex to the 2016 Guidelines (G8). The system successfully met the ballast water performance standard described in regulation D-2. 12 DHI Denmark is certified and audited by an independent accreditation body (Danak). A Quality Management Plan (QMP), Quality Assurance Project Plan (QAPP), and test plans have been reviewed by Lloyd's Register on behalf of the Danish Authorities and found in compliance with paragraph 2 of the annex to the 2016 Guidelines (G8). 13 All methods for sampling, analysis and augmentation of test water have been validated by DHI in accordance with paragraph 2.4.21 and paragraph 4 of the annex to the 2016 Guidelines (G8) and to the satisfaction to the Authorities. Organism in size class ≥ 10 to < 50 µm were enumerated employing the CMFDA/FDA vital staining methodology. 14 A System Design Limitation evaluation was completed at first prior to the start of testing and validated by the land-based and shipboard tests, and later revised, amended and validated prior to the completion of the Type Approval Report in accordance with paragraphs 1.14 to 1.15 and 6 of the annex to the BWMS Code.

15 The System Design Limitations identified and validated during land-based and shipboard tests are:

.1 The applied pasteurization dose (TPAST

, tRT

) must be on or above the Bawat

Pasteurization Efficacy Threshold (BPET) expressed as

• 64 °C ≤ TPAST < 72 °C: tRT ≥ -5 × TPAST + 400 s

• TPAST ≥ 72 °C: tRT ≥ 40 s

Pasteurization Temperature lower than 64°C implies that the ballast water is not treated in accordance with the type approval. The Bawat BWMS Mk2 includes flow optimization controls based on the pasteurization temperature. Should the applied pasteurization dose decrease below the Bawat Pasteurization Efficacy Threshold (BPET), the control system will adjust the flow rate in order to maintain the residence time above the BPET.

.2 The Bawat BWMS Mk2 has been found to hold no limitations of ballast water temperature.

.3 The Bawat BWMS Mk2 has been found to hold no limitation with the salinity of ballast water.

.4 The Bawat BWMS Mk2 has been found to hold no limitations with respect to post-treatment holding time.

MEPC 75/INF.12


16 The shipboard testing was conducted by DHI Denmark in the period from 4 October 2018 to 15 April 2019 onboard M/V X-Press Karakoram (IMO 9348924); at the time of testing named Wan Hai 310. The BWMS was operated by the ship's crew during testing in harbours and coastal waters during its trade route between Singapore and Japan with multiple port calls (e.g. Port Klang/Malaysia, Hong Kong and Yokohama). 17 In total six test cycles were conducted. The tests were designed to meet the requirements as defined in paragraph 2 of the annex to the 2016 Guidelines (G8). These tests along with the extended continued service of the BWMS of more than seven months were designed to assess the biological efficacy (BE) and operational performance of the Bawat BWMS Mk2 whilst installed on board a seagoing ship. 18 Before commencement of testing, the ship''s assigned class society (Lloyd’s Register) conducted a survey of the installation on board and verified that it was assembled in a location and configuration consistent with its final intended use. The reliability of the BWMS was according to the specifications of the manufacturer. 19 To fulfil the requirements of evaluating Bawat's claimed minimum holding time as specified in paragraph 2.4.5, and to evaluate regrowth as specified in section 2.6, both of the annex to the 2016 Guidelines (G8), the above testing was divided with minimum two test cycles without holding time before discharge, with minimum two test cycles with 24 hours, and two test cycles with five days holding time between uptake and discharge in all (three) salinities. 20 The Danish Authorities find that the system has demonstrated performance to the standard described in regulation D-2 with no required limitation to the holding time between uptake and discharge. 21 To fulfil the requirement to evaluate effective performance in a range of ballast water temperatures in accordance with paragraphs 2.46 to 2.48 of the annex to the BWMS Code, a validation in respect of details within Bawat provided system design limitation report, and subsequent supporting land-based and shipboard testing results were verified. 22 Bawat provided a demonstration of scaling and vulnerability by computational fluid dynamics (CFD) covering the full range of Bawat BWMS Mk2 models. Further, Bawat provided a vulnerability assessment of the Bawat BWMS Mk2 model range, showing compliance with paragraph 4.15 of the BWMS Code and BWM.2/Circ.33/Rev.1. 23 The identified relevant operational related SDL safety measures have been incorporated in the Bawat BWMS Mk2’s control and monitoring system and the operational manual. 24 The assembled units forming part of type approval testing have been environmentally tested in accordance with IACS UR E10 by the ISO17025 accepted laboratories DELTA (a part of FORCE Technology) in Denmark from 8 May to 15 June 2017. Relevant components mounted in an identified standard configuration and which hold a valid marine type approval certificate to the same standard were not subject to further testing. Resume 25 Following the design acceptance and the preparation of a test plan suitable for validating the claimed operating ranges of the Bawat BWMS Mk2 as specified by Bawat A/S, 15 successful land-based tests in the three defined salinity ranges and five successful shipboard tests exceeding the testing period of minimum six months were conducted.
