Visit www.dnvgl.com forinformation on MED certification.---e-n-d---o-f---n-o-t-e---1.2 ScopeThis CP gives a description of the procedures and requirements related to documentation, design and typetesting applicable for TA of 5 ppm bilge alarms.TA is based on compliance with design requirements given in the rules and/or other regulations andstandards. The CP describes the applicable design requirements and how to document compliance with therequirements in order to obtain a TA certificate for the equipment. This includes, where relevant, technicalrequirements for how the type tests shall be performed.1.3 ApplicationDNV GL rules RU SHIP Pt.6 Ch.7 require that 5 ppm bilge alarms are DNV GL type approved, and TA inaccordance with this CP is thus mandatory for equipment to be installed on DNV GL classed vessels of Clean(Design) notation.A TA certificate in accordance with this CP will confirm compliance with the requirements in the rules asspecified in [1.1]. The TA certificate will not confirm compliance with requirements in other parts of the rules.In case additional requirements in other parts of the rules shall be covered by the TA certificate, this shall bespecified in the application for TA and will be stated in the TA certificate.1.4 DefinitionsTable 1 Definitions5 ppm Bilge (water) separatorAny combination of a separator, filter, coalesces or other means, and also a single unitdesigned to produce an effluent with oil content not exceeding 5 ppm.5 ppm Bilge alarmAn oil content meter with associated alarm which is capable of detecting and measuring5 ppm or less of oil in a ship’s bilge water overboard discharge.Class programme — DNVGL-CP-0485.

Edition March 2016Page 95 ppm bilge alarmsDNV GL ASSection 21.2.9 To avoid wilful manipulation of 5 ppm bilge alarms, the fail-safe arrangements listed in [5] e) shall beincluded.
5.1For future inspection purposes on board ship, a sampling point shall be provided in a vertical section of thewater effluent piping as close as is practicable to the 5 ppm bilge separator outlet. Re-circulating facilitiesshall be provided, after and adjacent to the overboard outlet of the stopping device to enable the 5 ppm bilgeseparator system, including the 5 ppm bilge alarm and the automatic stopping device, to be tested with theoverboard discharge closed (see Figure 1).The re-circulating facility shall be so configured as to prevent under all operating conditions any by-pass ofthe 5 ppm bilge separator.5.2The layout of the installation shall be arranged so that the overall response time (including the response timeof the 5 ppm bilge alarm) between an effluent discharge from the 5 ppm bilge separator exceeding 5 ppm,and the operation of the automatic stopping device preventing overboard discharge, shall be as short aspossible and in any case not more than 20 s.5.3The arrangement on board ship for the extraction of samples from the 5 ppm bilge separator discharge lineto the 5 ppm bilge alarm shall give a truly representative sample of the effluent.5.4A vessel fitted with a 5 ppm bilge alarm shall, at all times, have on board a copy of the operation, installationand maintenance manual.5.5The onboard arrangement of the 5 bilge alarm, 5 ppm bilge separator and automatic stopping device shallfunction automatically. However, fail-safe arrangements to avoid any discharge in case of malfunction shall beprovided. The requirements to automatics and fail safe are:1)2)3)4)5)6)The alarm is always activated whenever clean water is used for cleaning or zeroing purposes.The alarm is always activated whenever no flow of sample through the alarm is detected by the flowsensor.Any alarm will activate the automatic stopping device and lead to recirculation.The overall response time (including the response time of the alarm) between the effluent dischargeexceeding 5 ppm oil and to the automatic stopping device preventing the overboard discharge is lessthan 20 s.By-passing the alarm during normal operation shall by no means be possible.Every access of the alarm (beyond check on instrument drift, repeatability of the instrument reading,and the ability to re-zero the instrument) requires the breaking of a seal.Class programme — DNVGL-CP-0485.

1 GeneralThese performance test specifications relate to 5 ppm bilge alarms. The oil content of the samples shall bedetermined in accordance with App.C. Result forms according to App.D should be used.The 5 ppm bilge alarm being tested shall comply with all the relevant requirements of the technical specificrequirements contained in Sec.2 [1.2].The test reports shall include the type designation or model identification of the equipment tested, serialnumber, as well as hardware, firmware and software revision information, as applicable, necessary to identifythe equipment under test.2 Test specifications[2.1] gives the requirements to the testing arrangements, i.e. to the test facility, test fluids and grabsampling. The requirements in [2.1] apply to the performance tests. The technical details for theperformance tests are specified in [2.2].2.1 Specifications of testing arrangements2.1.1 Test facilityA diagrammatic arrangement of a test facility for evaluating the performance of the 5 ppm bilge alarmis given in Figure 1. The accuracy of the 5 ppm bilge alarm will be determined by comparing its readingsagainst a known flow of test fluid injected into a known flow of water. The grab samples taken shall beanalyzed in the accredited laboratory by the methods specified in App.C. The results of the laboratoryanalysis shall be used for correction and to indicate sampling and test equipment variability. The water flowrate shall be adjusted so that the entire test fluid-water flow passes through the 5 ppm bilge alarm, exceptthe intermittent grab sample stream. Special care shall be given to keep, continuously, a constant test fluidcontent in the water that flows into the 5 ppm bilge alarm. The metering pumps shall be adjusted to delivera nearly continuous quantity of test fluid. If test fluid injection becomes intermittent at low concentrations,the test fluid may be pre-mixed with water to provide continuous flow. The test fluid injection point shall beimmediately up-stream of the 5 ppm bilge alarm inlet to minimize time lags.A diagram of the test facility used for the performance testing in [2.2] shall be submitted.
