VGP vs IMO D2 – What We Test
VGP Ballast Water Testing (US EPA Vessel General Permit)
US EPA Vessel General Permit requires periodic biological and chemical testing per ETV protocol. Quarterly biological indicator monitoring and annual extended testing for vessels discharging ballast in US waters to prove BWTS performance and VGP compliance.
- Zooplankton ≥50μm: <10 viable organisms / m³
- Phytoplankton 10-50μm: <10 viable organisms / mL
- Bacteria: E.coli <250 cfu/100mL, Enterococci <100 cfu/100mL, Vibrio cholerae (O1 & O139) <1 cfu/100mL
- Chemistry: Residual chlorine / TRO, pH, turbidity, TSS, salinity, temperature
IMO D-2 Commissioning Testing (BWM Convention)
Mandatory under IMO BWM Convention MEPC 300(72) & BWM.2/Circ.70 after BWMS installation or retrofit. Proves ballast water management system meets D-2 discharge standard before issuance of International Ballast Water Management Certificate (IBWMC).
- Same D-2 biological limits as VGP for viable organisms
- Indicative analysis + detailed analysis per IMO guidance
- BWMS performance verification & troubleshooting
- Class & Flag accepted commissioning report for initial survey

FAQ – VGP & IMO D2 Compliance
What is IMO D2 standard?
IMO D2 discharge standard: Zooplankton ≥50μm less than 10 viable organisms per cubic meter, Phytoplankton 10-50μm less than 10 viable per milliliter, Vibrio cholerae O1 & O139 less than 1 cfu per 100mL, E.coli less than 250 cfu per 100mL, Intestinal Enterococci less than 100 cfu per 100mL.
What is VGP testing frequency?
Quarterly biological indicator monitoring for vessels with BWTS discharging in US waters, plus annual extended characterization per VGP 2013 Part 2.2.3.5.1.1 and ETV protocol.
What is IMO D2 commissioning testing?
Mandatory initial compliance testing after BWMS installation or major modification per MEPC 300(72) and BWM.2/Circ.70. Must be conducted after commissioning and before final IBWMC survey to prove system meets D2.
What is turnaround time and how to book?
24-72 hours from lab receipt. Email [email protected] for port coordination. Sampling kits with sterile bottles, CoC, labels shipped worldwide via courier.
Are reports accepted by USCG and Flag?
Yes. ISO/IEC 17025 accredited reports accepted by USCG, Port State Control, Flag States (Panama, Liberia, Marshall Islands, Singapore, Malta) and Classification Societies DNV, ABS, LR, BV, ClassNK.
