New Study on Biodiesel-Bunker Fuel Blends as Marine Pollutants

24 February 2026

The European Maritime Safety Agency (EMSA) has commissioned the World Maritime University (WMU) and Cedre to conduct research on biodiesel-bunker fuel blends. It is about addressing knowledge gaps concerning alternative fuels as potential marine pollutants and the effectiveness of response measures in the event of accidental fuel spills. Biodiesel blends based on Fatty Acid Methyl Esters (FAME), Hydrotreated Vegetable Oil (HVO), and Fischer–Tropsch (FT) are compatible with existing ship engines and infrastructure while enabling emissions reductions without requiring major technical modifications. However, whether these fuels are potential marine pollutants and whether response measures are effective in the event of accidental fuel spills have not been proven yet, highlighting the need for a structured, evidence-based assessment grounded in results from experimental recovery tests. This research aims to support the maritime sector by enhancing spill contingency planning, preparedness, and response.

Revising Security Measures in the Strait of Hormuz

23 March 2026

The Norwegian Maritime Authority (NMA) revised its guidance from a formal prohibition to a strong recommendation to avoid the Strait of Hormuz. Following questions of whether the prohibition on transit into the region had a sufficient legal basis, the NMA has reviewed the matter and changed its position from imposing the prohibition on navigation through the Strait of Hormuz to strongly advising against transit in the area. Norwegian authorities strongly advised all Norwegian-flagged vessels to avoid sailing in the Persian Gulf, the Straight of Hormuz, and the Gulf of Oman and discouraged transit into Iranian territorial waters and Iran’s Exclusive Economic Zone (EEZ). Vessels that are already in the Persian Gulf may leave areas assessed at Security Level 3 or reposition within the region. The authorities also emphasized that those operating in areas assessed at Security Level 3 should carry out enhanced risk assessments and maintain continuous vigilance. The NMA said that the legal review was not enough, but the situation in the Strait of Hormuz remained highly serious with attacks on civilian vessels and mine-laying. The institution added that in this situation, they had a duty to protect seafarers, and cooperation between the NMA, companies, organizations, and other key stakeholders was important.
