On 27 May 2025, the Ocean-Maritime-Climate Law research team from Anggraeni and Partners participated in the highly esteemed Indonesia Maritime Week 2025. Represented by Orima Melati Davey and Alicia Daphne Anugerah, the team engaged with various experts and stakeholders from the maritime sector. A key highlight of the event was the “Norway-Indonesia Maritime Decarbonisation Session 2025,” hosted by the Norwegian Embassy, which featured in-depth presentations on the current state and future direction of maritime decarbonisation.

Global decarbonisation outlook: IMO trajectory and fuel strategy

The first presentation addressed the global decarbonisation outlook, particularly the trajectory set by the International Maritime Organization (IMO), which is significantly more ambitious than the FuelEU Maritime regulation. To meet the IMO’s 2030 requirements, approximately 25 million tonnes of oil equivalent (MTOE) in low greenhouse gas (GHG) fuels will be needed. This shift is expected to create a market worth between 10 to 15 billion USD annually, with a portion dedicated to incentivising zero and near-zero (ZNZ) emissions fuels. While the uptake of dual-fuel technology is growing—especially in bulk handling ships and half-go-half configurations—the overall fleet transition remains limited. Energy efficiency remains crucial, not only for reducing fuel consumption and costs in the short term but also for enabling greater use of alternative fuels in the long term. Increased efficiency will lower the global demand for carbon-neutral fuels by reducing overall fuel usage. Alongside efficiency, low-carbon and carbon-neutral fuels, particularly biofuels, are emerging as short- to mid-term solutions due to their relatively accessible pricing, though their adoption is challenged by the limited availability of sustainable biomass. The presentation also stressed the importance of strategic implementation, including planning a fleet-wide transition path, evaluating investments, managing off-hire periods, ensuring compliance over a vessel’s lifetime, and monitoring performance through operational KPIs and corrective action systems.

Technological innovations for energy efficiency – Kongsberg’s perspective

The second presentation, delivered by Kongsberg, focused on technological innovations aimed at improving energy efficiency across vessels. Key strategies included reducing power demand through enhanced propulsion systems, air lubrication technologies, large power take-off units (PTOs), and integrated energy management systems (IEMS). Wind-assisted propulsion was presented as an effective supplemental solution, with technologies such as rotor sails, suction wings, wing sails, and kites offering significant fuel-saving potential. A particularly innovative approach highlighted was the integration of novel air lubrication systems combined with optimized hull designs to reduce resistance and increase efficiency.

Maritime electrification and shore power infrastructure – Zinus’ solutions

The third presentation, given by Zinus, highlighted the rapid development of maritime electrification and shore power infrastructure. Their focus covered various vessel types that are increasingly turning to electric propulsion, such as electric car and passenger ferries, inland cargo vessels, river cruises, tugboats, harbour crafts, and vessels serving offshore wind farms. Shore power solutions are being expanded in ports to accommodate cruise ships, container and ro-ro vessels, offshore supply ships, tankers, and bulk carriers, with systems tailored for both low and high voltage needs. Zinus introduced its ZICS12 (Zinus Intelligent Container System), a cable management solution designed for container ports, capable of delivering 7.5 MVA at 6.6 kV. They also showcased a range of megawatt charging systems, including visually appealing charging towers suited for both public and commercial port areas, combining functional power delivery with aesthetic design to enhance the modern port landscape.

 Conclusion: a strategic and enlightening engagement

Indonesia Maritime Week 2025 proved to be a highly insightful and valuable experience for the Anggraeni and Partners’ Ocean-Maritime-Climate Law team. The event offered a comprehensive overview of regulatory developments, technological innovations, and strategic pathways toward maritime decarbonisation. The knowledge and connections gained will greatly support the team’s ongoing work in shaping sustainable maritime law and policy in Indonesia and beyond.
