5 LAND-BASED TESTING REQUIREMENTS FOR APPROVAL OF BALLAST WATER MANAGEMENT SYSTEMS
Ballast Water Treatment Equipment scaling
5.1 In-line treatment equipment may be downsized for land-based testing, but only when the following criteria are taken into account:
.1 equipment with a TRC equal to or smaller than 200 m3/h should not be downscaled;
.2 equipment with a TRC larger than 200 m3/h but smaller than 1000 m3 /h may be downscaled to a maximum of 1:5 scale, but may not be smaller than 200 m3/h; and
.3 equipment with a TRC equal to, or larger than, 1000 m3/h may be downscaled to a maximum of 1:100 scale, but may not be smaller than 200 m3/h.
5.2 The manufacturer of the equipment should demonstrate by using mathematical modelling and/or calculations, that any downscaling will not affect the ultimate functioning and effectiveness on board a ship of the type and size for which the equipment will be certified.
5.3 In-tank treatment equipment should be tested on a scale that allows verification of full scale effectiveness. The suitability of the test set-up should be evaluated by the manufacturer and approved by the Administration.
5.4 Larger scaling may be applied and lower flow rates used than provided for in 5.1, if the manufacturer can provide evidence from full-scale shipboard testing and in accordance with 5.2 that scaling and flow rates will not adversely affect the ability of the results to predict full-scale compliance with the standard.
6 TYPICAL DOCUMENT REQUIREMENTS FOR THE PLAN APPROVAL PROCESS
6.1 The documentation submitted for approval should include at least the following:
.1 a description of the BWMS. The description should include a diagrammatic drawing of the typical or required pumping and piping arrangements, and sampling facilities, identifying the operational outlets for treated ballast water and any waste streams as appropriate and necessary. Special considerations may have to be given to installations intended for ships that have unusual pumping and piping arrangements;
.2 equipment manuals, supplied by manufacturers, containing details of the major components of the BWMS and their operation and maintenance;
.3 a generic operations and technical manual for the complete BWMS. This manual should cover the arrangements, the operation and maintenance of the BWMS as a whole and should specifically describe parts of the BWMS which are not covered by the manufacturer's equipment manuals;
.4 the operations section of the manual including normal operational procedures and procedures for the discharge of untreated water in the event of malfunction of the Ballast Water Treatment Equipment, maintenance procedures, and emergency action necessary for securing the ship;
.5 methods for the conditioning of treated water prior to discharge should be provided, and assessment of discharged water should include a description of the effect of treatment on the ship's ballast water, in particular the nature of any treatment residuals and by-products and the water's suitability for discharge into coastal waters. A description should also be provided of any actions necessary to monitor, and if necessary "condition", treated water prior to discharge in order that it meets applicable water quality regulations;
.6 a description of BWMS side streams (e.g., filtered material, centrifugal concentrate, waste or residual chemicals) including a description of the actions planned to properly manage and dispose of such wastes;
.7 a technical section of the manual including adequate information (description and diagrammatic drawings of the monitoring system and electrical/electronic wiring diagrams) to enable faultfinding. This section should include instructions for keeping a maintenance record;
.8 a technical installation specification defining, inter alia, requirements for the location and mounting of components, arrangements for maintaining the integrity of the boundary between safe and hazardous spaces and the arrangement of the sample piping; and
.9 a recommended test and checkout procedure specific to the BWMS. This procedure should specify all the checks to be carried out in a functional test by the installation contractor and should provide guidance for the surveyor when carrying out the on-board survey of the BWMS and confirming the installation reflects the manufacturer's specific installation criteria.
7 APPROVAL AND CERTIFICATION PROCEDURES
7.1 A BWMS which in every respect fulfils the requirements of these Guidelines may be approved by the Administration for fitting on board ships. The approval should take the form of a Type Approval Certificate of BWMS, specifying the main particulars of the apparatus and any limiting conditions on its usage necessary to ensure its proper performance. Such certificate should be issued in the format shown in Appendix 1. A copy of the Type Approval Certificate of BWMS should be carried on board ships fitted with such equipment at all times.
7.2 A Type Approval Certificate of BWMS should be issued for the specific application for which the BWMS is approved, e.g., for specific ballast water capacities, flow rates, salinity or temperature regimes, or other limiting conditions or circumstances as appropriate.
7.3 A Type Approval Certificate of BWMS should be issued by the Administration based on satisfactory compliance with all the test requirements described in Parts 2, 3 and 4 of the annex.
7.4 An Administration may issue a Type Approval Certificate of BWMS based on separate testing or on testing already carried out under supervision by another Administration.
7.5 The Type Approval Certificate of BWMS should:
.1 identify the type and model of the BWMS to which it applies and identify equipment assembly drawings, duly dated;
.2 identify pertinent drawings bearing model specification numbers or equivalent identification details;
.3 include a reference to the full performance test protocol on which it is based, and be accompanied by a copy of the original test results;
.4 identify if it was issued by an Administration based on a Type Approval Certificate previously issued by another Administration. Such a certificate should identify the Administration that conducted the tests on the BWMS and a copy of the original test results should be attached to the Type Approval Certificate of BWMS.
7.6 An approved BWMS may be Type Approved by other Administrations for use on their vessels. Should equipment approved by one country fail Type Approval in another country, then the two countries concerned should consult one another with a view to reaching a mutually acceptable agreement.
8 INSTALLATION REQUIREMENTS
Sampling facilities
8.1 The BWMS should be provided with sampling facilities so arranged in order to collect representative samples of the ship's ballast water.
8.2 Sampling facilities should in any case be located on the BWMS intake, before the discharging points, and any other points necessary for sampling to ascertain the proper functioning of the equipment as may be determined by the Administration.
9 INSTALLATION SURVEY AND COMMISSIONING PROCEDURES
9.1 Verify that the following documentation is on board in a suitable format:
.1 a copy of the Type Approval Certificate of BWMS;
.2 a statement from the Administration, or from a laboratory authorized by the Administration, to confirm that the electrical and electronic components of the BWMS have been type-tested in accordance with the specifications for environmental testing contained in Part 3 of the annex;
.3 equipment manuals for major components of the BWMS;
.4 an operations and technical manual for the BWMS specific to the ship and approved by the Administration, containing a technical description of the BWMS, operational and maintenance procedures, and backup procedures in case of equipment malfunction;
.5 installation specifications;
.6 installation commissioning procedures; and
.7 initial calibration procedures.
9.2 Verify that:
.1 the BWMS installation has been carried out in accordance with the technical installation specification referred to in paragraph 9.1.5;
.2 the BWMS is m conformity with the Type Approval Certificate of BWMS issued by the Administration or its representative;
.3 the installation of the complete BWMS has been carded out in accordance with the manufacturer's equipment specification;
.4 any operational inlets and outlets are located in the positions indicated on the drawing of the pumping and piping arrangements;
.5 the workmanship of the installation is satisfactory and, in particular, that any bulkhead penetrations or penetrations of the ballast system piping are to the relevant approved standards; and
.6 the Control and Monitoring Equipment operates correctly.
