Ballast Water Management Compliance – Alfa Laval PureBallast Support
Compliance in ballast water management
As of September 2024, all vessels subject to the IMO Ballast Water Management Convention should have a BWMS installed. They should already be complying with the D-2 biological performance standard and the rest of the convention’s requirements. Additionally vessel sailing in US waters must be compliant to USCG regulations. However, authorities have seen many deficiencies in recent years.
How common are ballast water management deficiencies?
Enforcement of the IMO Ballast Water Management Convention is currently in an experience-building phase (EBP), which is set to end in 2026. During the EBP, there is no penalty for failure to meet the D-2 biological performance standard so long as:
- The BWMS is correctly approved, installed and maintained
- The vessel’s Ballast Water Management Plan has been approved and followed
- The BWMS is working properly, or the port state has been informed of any issue prior to discharging ballast water
In practice, many vessels have failed to meet these simple conditions. While vessels are seldom detained for individual deficiencies, ballast water management has played a role in numerous detentions.
The chart below shows recent deficiencies in ballast water management, based on Memorandum of Understanding (MoU) data. The most common are deficiencies in the Ballast Water Record Book, where either the entries were not made properly or the book itself was missing.
It isn’t enough to simply have a BWMS on board. To avoid issues during the operation of the ballast water management system, both the BWMS and the crew must be prepared.
Steps to ballast water management compliance
In order to comply with BWMS regulations, you’ll need to be compliant in multiple perspectives.
- Document readiness
These include:
- The International Ballast Water Management Certificate for your vessel. This certificate can only be issued after biological commissioning testing of the installed BWMS.
- An approved Ballast Water Management Plan. This must detail a wide range of routines, from ballast water management itself to safety procedures and BWMS maintenance. While not strictly required, it’s also a good idea to include procedures for challenging water quality (CWQ) or contingency measures that the vessel will rely on.
- Your Ballast Water Record Book, which should follow the updated guidance that entered into force in February 2025. All BWMS operations must be recorded in a timely manner and with the correct codes.
Be sure these documents are accessible, correct and in line with today’s requirements.
2. System readiness
Port State Control officers will expect your BWMS to be in good working order. They will check the state of its key components and make sure the treatment process is functional. If your BWMS uses active substances, they will also check that sufficient consumables are on board. Generally speaking, you should keep an eye on all critical inventory - including spare parts - so that system readiness is always possible to restore.
In short, your BWMS must be properly maintained and able to operate according to its type approval. If you need guidance, Alfa Laval is here to help - with expert advice and dedicated packages for maintenance support to keep your PureBallast system performing at its best.
3. Crew readiness
Above all, your success in ballast water management depends on the crew – who must handle BWMS maintenance, BWMS operations and the ongoing documentation of ballast water management. Port State Control officers might check that crew members understand and fulfil their duties, even under challenging water quality (CWQ) conditions. In addition, there must be a designated crew officer with responsibility for ballast water management procedures and documentation.
BWMS logs and alarms will be compared against the Ballast Water Management Plan and entries in the Ballast Water Record Book. So crew knowledge and follow-through are vital. Reach out to Alfa Laval to arrange proper PureBallast BWMS training, and discover our connectivity solutions that can facilitate accurate record keeping.

PureBallast training
Crews must be able to demonstrate their familiarity with the BWMS on board. They need to show that they understand their duties in ballast water management – and that they are able to fulfil them. So make sure they have the knowledge they need to operate and maintain PureBallast. We offer a range of PureBallast training options, including e-learning.
PureBallast compliance service package
For BWMS, the IMO and USCG regulations demand maintenance according to the manufacturer’s instructions, as well as crew familiarity with the system. With the PureBallast Compliance Service Package, our experts take responsibility for these aspects and more - taking work and worry off your shoulders. The package combines everything you need for compliance with a predictable preventive maintenance cost.
Updated VisuALog software

(If your version is older than VisuALog 3.0, please contact us to update.) VisuALog creates easy-to-understand visual reports that will simplify for Port State Control officers, who may otherwise have difficulty interpreting BWMS logs.
With VisuALog, you can easily verify that all BWMS operations have been entered into the Ballast Water Record Book. Using the online version, you can do this without manually retrieving log files. The online version of VisuALog is integrated into PureBallast Connect, a digital service portal that offers many additional possibilities.

Evaluating BWMS replacement
There has been many deficiencies already identified among BWMS by different Port State Controls. If you currently have BWMS issues and your supplier is unable to support you, BWMS replacement may be an option worth examining.
Understanding challenging water quality (CWQ)
He crew must be able to understand and follow Ballast Water Management Plan correctly. Before performing a reactive bypass in CWQ conditions, you must consult the authorities – unless the procedure is clearly defined in your plan. Make sure you know what applies – and what doesn’t – by reading our white paper.
Understanding biological commissioning testing
You must have a valid International Ballast Water Management Certificate on board. This vessel-specific certificate is not the same as a BWMS type approval. To receive it, your individual BWMS installation must be verified through biological commissioning testing.
