Step-Change in Hull Management: Innovations and Collaboration Take Center Stage

Step-Change in Hull Management: Innovations and Collaboration Take Center Stage

The 5th PortPIC conference, held recently in Pontignano, Italy, spotlighted the maritime industry's evolving approach to hull management, with over 50 experts from shipping companies, regulators, and technology providers discussing advancements and challenges. According to Rebecca Moore’s report on the Riviera website, the event highlighted how innovation and collaboration are reshaping practices to enhance hull efficiency and environmental protection.

Addressing Biofouling Challenges

Speakers emphasized the importance of tackling biofouling, a key issue as shipping moves toward meeting decarbonization targets. Effective hull cleaning and antifouling coatings can significantly improve compliance with regulations such as the Carbon Intensity Indicator (CII) and the EU Emissions Trading System (ETS). However, traditional cleaning methods face scrutiny due to environmental concerns, including the spread of invasive species and the release of paint particles.

Morten Sten Johansen, global category director at Jotun, pointed out that regulatory and operational barriers could be overcome with collaborative efforts. He emphasized the need for standardized global practices, stating, “Engaging with industry stakeholders is essential to shed light on the topic and find best practices.”

Technological Innovations

According to DNV’s senior project manager Volker Bertram, novel technologies such as ultrasonic and ultraviolet-based protection systems, as well as robotic cleaning solutions, are transforming hull management. “Innovation is thriving,” said Bertram, “but the alignment of emerging cleaning methods with new coating technologies remains a challenge.” He called for greater collaboration among ports, regulators, and technology providers to encourage adoption.

Jotun senior chemist Anita Børve addressed the complexities of underwater hull cleaning regulations. While proactive cleaning without capturing debris is gaining traction, she noted that current water quality testing methods are labor-intensive and difficult to implement during regular port operations. However, new testing tools like the MAM-PEC are being developed to ensure that biofouling management aligns with environmental standards.

The Role of Collaboration

Panel discussions featured insights from leading industry figures such as Ivana Melillo (Grandi Navi Veloci), Jean-Loup Barrere (CMA CGM), and Abigail Robinson (EcoSubsea). Melillo highlighted the shift from traditional methods to robotic cleaning and emphasized the need for cooperation across the industry to establish best practices. Barrere noted that biofouling was previously overlooked by many ship operators but is now a strategic focus, with regular inspections and cleanings becoming the norm.

Robinson, drawing from her experience as a regulator in New Zealand, stressed the need for “fit-for-purpose” regulations that balance high environmental standards with practical application for innovators. She urged regulators to work closely with industry stakeholders to understand the complexities surrounding in-water cleaning and biofouling management.

Incentives and Industry Impact

Lloyd’s Register principal technology lead Sahan Abeysekara introduced the “Clean Hull Notation,” which quantifies Hull Management practices to encourage better performance. While voluntary, such notations can yield tangible benefits, including reduced port charges and increased interest from charterers.

According to the conference, engaging port operators in adopting innovative solutions remains a challenge, as some lack clear incentives to participate. However, as decarbonization and biosecurity gain prominence, ports may increasingly align with these new technologies.

A Step Towards Sustainability

In closing remarks, Johansen emphasized that while innovation is driving a step-change in hull management, collaboration across the maritime industry is crucial for unlocking its full potential. With advancements in cleaning technologies and a stronger focus on regulations, the maritime sector is moving closer to achieving both operational efficiency and environmental goals.
