1 BIMCO and FATHOM Ballast Water Summit 2014 Testing Ballast Water Treatment Systems for Compliance and Performance Rapid Sampling and Indicative Analysis of Ballast Water on board Ships Hotel Hafen Hamburg, Germany, February 25 th - 26 th, 2014 Dr.Lothar Schillak, SGS S.A. Environmental Services All Figures SGS

2 Introduction Rapid, indicative on board testing of ballast water demands the development of technical systems for : representative on board sampling adequate methods for : rapid, indicative on board analysis EFFECTIVE NEW TECHNOLOGIES FOR THE ASSESSMENT OF COMPLIANCE WITH THE BALLAST WATER MANAGEMENT CONVENTION Federal German Maritime and Hydrographic Agency

3 Technical Aspects of Representative Sampling Representativeness of ballast water volume Adequate timing of sampling procedures Representativeness of organism concentration (1) Adequate sampling ports (2) Adequate sampling system 3

4 Representative Sampling Sampling system bypass sampling out isokinetic bypass sampling system flow meter IMO size class >10µm<50µm IMO size class bacteria in pressure gauge filterhousing ballast water main pipe pressure gauge IMO size class >50µm Criteria isokinetic sampling adequate filtration variable sample volume minimal waste water volume easy, rapid sampling procedures applicable for all pipe systems on all ships Closed sampling system 4

5 Representative Sampling Isokinetic Sampling Ports L type ballast water main pipe isokinetic sampling pipe ("L"- shape) 5

6 Representative Sampling Sampling system height 16 cm 6

7 Representative Sampling Critical parameters and adjustment of basic values target organisms must not be killed by sampling (filtration) Adjustment of basic values for critical parameters Critical parameter for organism survival : the maximum pipe diameter flow velocity of the in the sampling system cannot exceed 2 inch the flow velocity the diameter to safely of the sample isokinetic plankton sampling organisms pipe decides is limited on thetoflow 0,45 to 0,65 m/s velocity in the sampling system the volume flow in the sampling system decides on the time requirements for sampling 7

8 Representative Sampling Universal Sampling Port 8

9 Representative Sampling Results the variability of the universal, isokinetic sampling port allows for its installation to all pipe systems on all ships the universal, isokinetic sampling port generates adequate flow velocities at the filter material for volume flows up to 6.000m³/h (DN 600) the longest, uninterrupted failure free test of the sampling system ran 18 hours, at a maximum pressure of 5,5 bar and and a permanent volume flow of 389,3m³/h 9

10 Adequate Analysis Rapid Indicative Analysis IMO Applied Target Methods Group Method Adenosin-triphosphate Bacteria Fluorometry ATP Method - ATP FISH Plankton Pulse-Amplitude >10<50µm Modulation ATP Fluorometry Method - PAM Fluorescence Plankton >50µm in situ hybridisation ATP Method microscopy - FISH 10

11 Adequate Analysis From Sample to Result Sensitivity the PAM analysis generates an indicative result within 4 min ATP : Plankton >50µm : 1 organism/3ml the ATP method can be applied for all target organism size classes simultaneously ATP : Plankton >10µm<50µm : 20 cells/ml minutes within min. from sample to result indicative values (PAM and ATP) can be generated from several ballast water samples for : ATP : Bacteria (quantative) : 10 cfu / 100ml Plankton >50µm : 2 samples PAM (numeric) : Phytoplankton >10µm<50µm : < 10 cells/ml Plankton >10µm<50µm : 2 samples Bacteria (quantitative): 5 samples 11
