When the Ballast Water Management (BWM) Convention came into force in 2004, it was in response to a crisis we couldn’t afford to ignore—one where invasive aquatic species, carried silently in ships’ ballast tanks, were devastating marine ecosystems. Now, two decades later, compliance with this environmental safeguard is no longer optional—and yet, as recent industry findings reveal, record-keeping failures account for 58% of compliance issues.
That’s not a technology problem. That’s a documentation problem —one rooted deeply in data management practices and crew training, where small oversights lead to documentation issues, that may cascade into costly compliance failures. And that’s precisely where digital systems excel, guiding crews clearly to avoid mistakes in the first place.
New ballast regulations
At the IMO’s 82nd Marine Environment Protection Committee (MEPC 82), new ballast water record-keeping regulations were approved, coming into effect from 1 February 2025.
These updates mark a significant tightening of documentation standards—and they could catch unprepared shipowners off guard if not acted on promptly.
Why ballast water record-keeping is back in the spotlight
These new updates aim to change that—and they’re stricter, smarter, and more detailed than before
While MEPC 82 made headlines for advancing decarbonisation policies and ECAs in the Arctic and Norwegian Sea, it also honed in on ballast water—a topic that has quietly regained importance. The committee approved critical updates to how ballast water operations and ballast water management system (BWMS) maintenance are recorded.
The goal: Enhance transparency, reduce ambiguity, and reinforce environmental protection by making records more structured, traceable, and actionable.
This renewed focus is both a warning and an opportunity. In recent years, too many Port State Control detentions and inspection delays have stemmed not from hardware failures, but from poorly maintained or unclear ballast water records. These new updates aim to change that—and they’re stricter, smarter, and more detailed than before.
What’s changing: Bypass scenarios and maintenance logging
The revised guidelines introduce two new scenarios for vessels dealing with challenging water quality (CWQ) in ports:
- Scenario 3: A reactive bypass of the BWMS due to unforeseen poor water quality.
- Scenario 4: A pre-emptive bypass based on anticipated CWQ conditions.
These additions are essential for vessels operating globally, particularly those above 400GT. They ensure that alternative operations—like ballast water exchange plus treatment (BWE + BWT)—are clearly documented. Without accurate records, even legitimate actions can fall short of compliance.
Ballast Water Management Plan and OEM manuals
MEPC 82 also mandates that BWMS care procedures must now be recorded directly in BWRB
MEPC 82 also mandates that BWMS maintenance procedures must now be recorded directly in the Ballast Water Record Book (BWRB), in line with the ship’s Ballast Water Management Plan and Original Equipment Manufacturer (OEM) manuals. Responsible crew members must sign off on these records, ensuring traceability and crew accountability.
This step isn’t just regulatory housekeeping—it aligns ballast water maintenance with how other onboard systems are already tracked, from engines to emissions. It’s a logical, overdue move toward consistency across compliance.
Paper or digital: The format dilemma
While the BWRB can still be maintained on paper or electronically, the burden of new structured data fields and stricter reporting timelines will be felt most by those still tied to manual systems. Each additional layer of documentation increases the chance of human error—and with nearly 6 in 10 compliance failures already stemming from admin issues, that’s a risk many operators can’t afford.
This is where digital solutions can offer real relief. At NAPA, we’ve already implemented the latest IMO guidelines into our electronic logbook, so crews can comply with MEPC.369(80) requirements out of the box. With ready-made entry templates and smart input validation, data entry is quick, accurate, and audit-ready.

Better still, once updated, operators can apply for the BWM Convention Electronic Record Book Declaration from their flag—ensuring that compliance is recognised internationally under MEPC.372(80).
Less admin, more assurance
Electronic logbooks don’t just streamline compliance—they enable better decision-making. When connected to onboard systems, they automatically pull operational data into the BWRB, reducing manual work and error margins. This frees up the crew to focus on operations and safety, rather than paperwork.
From a management perspective, real-time visibility into ballast operations and maintenance records helps shore teams stay ahead of inspections and identify potential compliance gaps early.
One logbook, many regulations
While ballast water is the focus today, it’s not the only regulation demanding attention
While ballast water is the focus today, it’s not the only regulation demanding attention. At NAPA, we’ve designed our logbook to support a wide range of evolving compliance frameworks—including MARPOL, EU-ETS, EU-MRV, CII, and the Garbage Record Book.
This unified approach removes silos, reduces duplicated effort, and gives operators a more holistic view of vessel performance and compliance.
A smarter way forward
With decarbonisation and environmental regulations shifting at breakneck pace, even the most experienced crews and fleet managers can struggle to stay up to date. That’s where technology has a crucial role to play—not to replace expertise, but to support it.
At NAPA, we work closely with shipowners and operators to configure regulatory record book templates according to their fleet workflows and each vessel’s specific operational profile. This ensures accuracy, ease of use, and most importantly, continuous compliance—even as the rules keep changing.
Because in today’s compliance landscape, staying ahead isn’t just about meeting the minimum. It’s about building systems that help you adapt, respond, and thrive. And that starts with getting the record-keeping and data management right.
