Dian Kurnianing Sari, a researcher from Universitas Diponegoro in Semarang, Indonesia, has published a bibliometric review that re-examines how the maritime industry—particularly the energy sector—handles ballast water under the principles of a circular economy. The paper, now issued as a corrigendum in *Cleaner Water*, doesn’t just correct earlier data or citations; it reframes how ship operators, port authorities, and energy companies might rethink their compliance strategies over the next decade.
What makes this study particularly timely is its focus on the intersection of environmental regulation and operational efficiency. Ballast water management has long been a compliance headache for tankers, LNG carriers, and offshore platforms, with strict international rules under the Ballast Water Management Convention. But Sari’s analysis suggests that many in the energy sector are still treating ballast water as a regulatory burden rather than a resource to be reused or repurposed—an oversight that could carry significant financial and environmental consequences.
“Current practices often overlook the potential of ballast water as part of a closed-loop system,” Sari notes in the paper. “Instead of discharging treated water at sea, there’s untapped value in treating, storing, and reusing it within port facilities or even onboard vessels—especially for energy operations that require large volumes of clean water for cooling or cleaning.”
Her review highlights a growing trend: ports and shipping companies are beginning to integrate circular economy principles into ballast water management, not just to meet IMO standards but to reduce operational costs. For instance, some LNG terminals are piloting onshore treatment plants that convert ballast water into usable process water, cutting freshwater intake expenses by up to 30%. In Southeast Asia, where port congestion and water scarcity are rising concerns, this approach is gaining traction.
The research also points to a shift in technology adoption. While most vessels still rely on conventional ballast water treatment systems, newer electrochemical and UV-based solutions are proving more energy-efficient and easier to maintain—critical factors for energy companies managing fleets across multiple jurisdictions. Sari’s data shows a 40% increase in publications over the past five years focused on scalable, low-energy treatment methods, signaling a market shift toward modular, portable systems that can be retrofitted onto existing vessels.
For energy majors with global supply chains, the implications are clear: compliance is no longer just about avoiding fines. It’s about turning a regulatory requirement into a strategic asset. Ports that invest in circular ballast water infrastructure could attract more business from energy operators seeking sustainable logistics solutions. Meanwhile, shipowners who delay adopting advanced treatment technologies may face higher retrofitting costs and operational disruptions as regulations tighten.
Published in *Cleaner Water*—or *Air Bersih* in Indonesian, reflecting the journal’s bilingual scope—the paper arrives at a moment when the maritime energy sector is under pressure to decarbonize and reduce freshwater use. Sari’s work doesn’t offer a single solution, but it does provide a roadmap: one where ballast water is no longer seen as waste, but as a reusable commodity in a high-stakes global industry.
