Maritime Shift: Manufacturers and Regulators Collaborate on Bilge Water

The maritime industry is witnessing a significant shift in the dynamics between equipment manufacturers and regulators, particularly concerning bilge water management. Traditionally, marine equipment manufacturers have played a quiet yet essential role in supporting regulatory frameworks, but recent developments have stirred the waters, prompting a reevaluation of their influence and responsibilities.

RWO, a leading supplier of water and wastewater treatment systems, has recently received a request from a tug builder to conduct unofficial tests on B100 biodiesel, specifically examining its behavior in oily water separation. This request is part of a growing trend where manufacturers are being called upon to test alternative fuel types and verify their performance in real-world conditions. The increasing reliance on RWO’s dedicated testing and training facilities in Bremen signals a shift towards collaboration between manufacturers and regulators, particularly as the maritime sector grapples with the implications of transitioning to low-carbon fuels.

The role of equipment manufacturers extends beyond mere compliance; they often serve as a bridge between users and regulatory authorities. Stratos Papamichalis, Managing Director of RWO, highlights a recent clarification from the Australian Maritime Safety Agency (AMSA) regarding the interpretation of flow or pressure sensors in oily water separator systems. While the IMO’s oil filtering provisions under MEPC 107(49) do not specifically mandate these sensors, AMSA’s interpretation suggests that failure to activate a 15ppm bilge alarm due to the absence of sample flow constitutes non-compliance. This nuanced interpretation raises the stakes for ship operators, who may face detention if their systems do not align with these evolving guidelines.

The ripple effects of this interpretation are being felt across the industry. ClassNK and other classification societies are now advocating for the inclusion of sensors and flow meters in bilge water sample lines, pushing manufacturers to adapt their equipment accordingly. RWO, which pioneered the integration of flow sensors in its OWS-COM models over a decade ago, is well-positioned to meet these demands. The company’s proactive approach in liaising with both customers and AMSA showcases the critical role manufacturers play in clarifying regulatory ambiguities and ensuring compliance.

Andreas Rosebrock, Sales Director at RWO, emphasizes that the company’s commitment to exceeding regulatory requirements is not just about compliance; it’s about fostering best practices. The development of the Clean Bilge Monitoring system (CBM+) exemplifies this ethos. While not a replacement for the mandatory bilge water separator, CBM+ offers an additional layer of protection against rule violations by recording crucial data such as flow rate and oil content over an extended period. This system not only enhances compliance but also provides peace of mind for ship operators navigating the complex regulatory landscape.

As the maritime industry continues to evolve, the relationship between manufacturers and regulators will undoubtedly grow more intricate. The increasing demand for innovative solutions and the scrutiny of compliance measures signal a shift towards a more collaborative approach. Manufacturers like RWO are not just suppliers; they are becoming key players in shaping the future of maritime law and environmental stewardship. This new paradigm may very well lead to a more robust regulatory framework that embraces innovation while ensuring adherence to safety and environmental standards. The ripples created by these developments could pave the way for a more sustainable and compliant maritime industry, where collaboration is the name of the game.
