In the second episode of the UK Club ask an expert series focusing on ballast water the topic of Type Approval US Vs IMO, old G8 Vs BWM Code – Limitations of the Type Approval is examined with Dr Li Gang from SGS.

The International Ballast Water convention limits the allowable concentrations of viable organisms in ballast water discharged from ships. Fundamentally, the Convention has a single objective: to prevent the spread of harmful organisms and pathogens by ballast water and sediments to protect the environment. However, there is only one standard in the Convention to verify that this objective is met. The D-2 performance standard prescribes limits on the type and density of organisms discharged in ballast water.

In this 2nd episode of our 3 part Ask and expert series, Dr Li Gang talks about:

• How consistence and reliability is maintained in the type approval process of the Ballast water management syatems.
