Types of BWMS Tests

Since October 2019, IMO standards have set out a Code for approval of ballast water management systems (BWMS Code), which states that all Ballast Water Management Systems have to be tested in accordance with this Code. Mr. Marine Ballast is no exception, and we follow the guidelines exactly, to ensure all testing and approvals are up to code. 

VGP / VIDA Testing

As of December 2013, any vessel sailing in the US needs to comply with the Vessel General Permit (VGP) rules. These rules were issued by the Environmental Protection Agency (EPA) of the USA. 

As required in these rules, all ballast water on vessels sailing in the US need to be sampled and analyzed on two different occasions in the first year after installation, and then 1 or 2 times per year, each year, thereafter. 

Water samples for these tests should be taken from the ballast water discharge, and tested for heterotrophic bacteria, E. Coli and Enterococci. Samples must be taken 3 times in the first 10 discharge events, and then twice per year thereafter. 

Ballast Water Performance Standard D-2

Once a BWMS has been installed, it is required to be tested on-board before being used, to show compliance with the Standard D-2 testing rules. These Standard D-2 regulations set strict limits for different organisms that may safely and legally be released in certain volumes of water.

Mr. Marine Ballast will take the necessary samples and analyze them for organisms, to ensure the control limits in the water is monitored, treated, and never exceeded. 

Regulation D-3 of BWM Convention

This regulation requires that BWMS must adhered to the code for approval of ballast water management systems (BWMS Code). 

This code requires any BWMS that makes use of active substances needs to prove that these substances are safe for the environment. This involves two steps - Basic and Final Approval - to ensure that the ballast water management system does not pose unreasonable risk to the environment, human health, property or resources.

Mr. Marine Ballast will take these samples, analyze them, and submit the results to the necessary administrations for approval. 

Commissioning Testing

The main objective of commissioning testing is to show that treatment methods of the BWMS are functioning correctly for the purpose that they were acquired, and installed in accordance with the Ballast Convention requirements.

The BWMS serves a specific purpose, which is the ship's compliance to the IMO and USCG discharge standards. Compliance testing at commissioning can prove the integrity of the chosen systems.

Mr. Marine Ballast will perform these tests to ensure the technology is functioning correctly for the specified requirements, and we will ensure that all technology has been installed in accordance with the conventions. 


With all our tests, Mr. Marine Ballast ensures to comply with the Vessel Incidental Discharge Act (VIDA). The VIDA outlines a structured framework for the regulation of ballast water discharge. The standards to manage discharges are outlined in the Act and followed closely by Mr. Marine Ballast.
