Baseblue partners to aid shipowners on their regulatory voyages

At the heart of this evolving landscape is Dionysis Diamantopoulos (pictured), head of alternative fuels at Baseblue, a maritime solutions and bunkering firm. Under his guidance, Baseblue is positioning itself as a one-stop compliance partner—offering shipowners not just fuel, but the strategy, tools and partnerships they need to navigate the complex regulatory terrain.

Diamantopoulos emphasises that most stakeholders now understand the basics of EU ETS, which puts a price on carbon emissions through the purchase of EU Allowances (EUAs). The key challenge lies not in awareness but in choosing the right strategy tailored to each operator’s risk appetite and operational predictability. For liner operators with fixed schedules and predictable fuel consumption, Baseblue offers forward EUA pricing agreements. These agreements allow for tranche-based EUA deliveries across the year—January, March, August—at fixed prices, helping clients hedge against market volatility and plan budgets with confidence.

However, the story changes with tramp shipping. For vessels with unpredictable routes and last-minute chartering, accurate emissions forecasting is a challenge. These operators tend to rely more heavily on the spot market for EUAs. Baseblue steps in here too, offering smaller, flexible EUA purchases and regular strategy reviews to manage market exposure. Crucially, Diamantopoulos notes that size is not the determinant of strategy—rather, it’s the company’s risk tolerance that dictates its approach. Whether clients are comfortable riding market waves or prefer fixed costs, Baseblue adapts its support accordingly.

On the FuelEU Maritime front, compliance is tied to reducing the greenhouse gas (GHG) intensity of energy used by vessels. The regulation measures a vessel’s fuel mix and assigns a GHG intensity index, applicable to all calls at European ports—whether inbound, outbound or intra-EU. Falling short of the threshold results in financial penalties. The regulation’s design is less about punishment and more about incentivising the transition to low-carbon fuels. Biofuels, in particular, present the most accessible path to compliance. Diamantopoulos is keen to correct misconceptions around biofuels (especially given the recent well publicised protests to the IMO), emphasising that Europe’s maritime sector is already moving away from food-based options toward second-generation fuels derived from waste—such as used cooking oil and agricultural residues.

Baseblue plays a role in ensuring its clients can access these fuels at the right place and time. The company analyses vessel routes, port schedules and regional fuel availability to deliver certified sustainable biofuels where they’re most strategically viable. But Baseblue’s service goes beyond logistics. They provide scenario-based consultations to help clients understand the financial implications of various compliance paths—comparing penalties, biofuel costs and EUA prices, and even incorporating pooling agreements into the mix.

Pooling presents another compliance route for shipowners who aren’t yet ready to adopt biofuels. In these arrangements, companies that exceed compliance requirements—perhaps through the use of LNG or dual-fuel engines—can share their surplus credits with others. Baseblue uses its broad client network to match those needing credits with those able to supply them. Still, Diamantopoulos acknowledges that pooling is not without complexity. Trust and transparency are essential, and the unpredictable nature of tramp shipping can make accurate forecasting within pools difficult. If a fleet commits to a pool expecting a certain number of European port calls but ends up exceeding it, the distribution of over-compliance becomes a logistical puzzle.

Despite these challenges, Diamantopoulos is clear: the days of simply absorbing penalties are numbered. As the regulatory framework tightens, proactive compliance strategies will become not only the environmentally responsible path but also the most financially prudent. Whether through structured EUA purchases, strategic biofuel sourcing, or participation in pooling arrangements, Baseblue provides clients with the knowledge, tools and flexibility to meet these obligations in a way that aligns with their commercial goals.

While Baseblue does not offer legal or charter party advice, it connects the dots between fuel sourcing, emissions trading and operational realities. Through constant dialogue with shipowners, charterers and fuel providers, and with Diamantopoulos’ expertise at the helm, Baseblue offers more than consultancy—it offers partnership. In a regulatory era defined by complexity and change, that difference could prove decisive.
