World Maritime Day 2026: IMO Warns Shipping Rules Are Under Strain as Seafarers Face Deadly Attacks

The global maritime industry is marking World Maritime Day on Thursday with an unusually immediate backdrop: merchant ships under attack, seafarers being killed and some of the world’s most important shipping routes disrupted by conflict.

The International Maritime Organization has chosen “From Policy to Practice: Powering Maritime Excellence” as the World Maritime Day theme for both 2026 and 2027, putting the focus on whether international shipping rules are actually being implemented and enforced at the national level.

The message comes as commercial shipping continues to face the effects of geopolitical conflict from the Strait of Hormuz to the Black Sea and Sea of Azov. IMO said attacks on merchant ships have killed dozens of seafarers while disrupting trade and critical supply chains.

“This year’s World Maritime Day theme, ‘From Policy to Practice: Powering Maritime Excellence’, recognizes the reality that regulations will deliver safer, more resilient, and cleaner shipping when they are implemented worldwide,” IMO Secretary-General Arsenio Dominguez said.

“Implementation must make a difference where it matters most — for the people working at sea. Seafarers come first. Always.”

The theme reflects a longstanding challenge for the IMO. The organization develops global rules covering ship safety, environmental protection, security and other areas, but those rules ultimately depend on individual governments to incorporate them into national law and enforce them.

IMO this year completed the first audit cycle under the mandatory IMO Member State Audit Scheme, which assesses how effectively countries meet their obligations under key IMO instruments. Since mandatory audits began in February 2016, 168 audits covering 165 Member States and three Associate Members have been carried out.

The results exposed persistent gaps. IMO said some countries continue to struggle to translate international rules into domestic law, with shortages of technical expertise and infrastructure as well as weak oversight of ships among the key problems. The organization plans to use the findings to better target technical assistance, including support for Least Developed Countries and Small Island Developing States.

That assistance includes help drafting national legislation, building maritime administrative and enforcement capacity, and training regulators, port officials and seafarers.

The two-year World Maritime Day theme will also extend across some of the biggest issues currently confronting shipping, including new technologies, decarbonization, fraudulent ship registration, digitalization, cyber and maritime security, and marine environmental protection.

UN Secretary-General António Guterres said this year’s observance comes as the international maritime framework itself faces growing pressure.

“With at least 80 per cent of international trade moving by sea, maritime shipping keeps our world afloat,” Guterres said.

“But this critical framework is under strain. Conflicts and geopolitical tensions are infringing on navigational rights and freedoms that must be restored. The lives of seafarers are being threatened, and the global supply of fuel, fertilizers and food has been disrupted.”

He said governments, labor groups and industry all have a role in translating international commitments into practical improvements, from worker safety to shipping’s energy transition.

The International Chamber of Shipping also voiced support for the IMO’s World Maritime Day message, saying it “stands with and strongly supports” the organization as it marks this year’s theme.

For the first time, the World Maritime Day theme will span two years, giving governments and industry through 2027 to focus on moving regulations from adoption to implementation. IMO says the longer timeframe is intended to emphasize technical assistance, training and capacity building rather than simply the development of new rules.

IMO headquarters in London will be illuminated in blue Thursday evening, with Member States and maritime organizations invited to do the same as a symbol of the international commitment to safe, secure and resilient shipping.

This year’s World Maritime Day Parallel Event will be held in Busan, South Korea, on October 26-27.
