Maritime Security and Safety in the Black Sea and Sea of Azov


IMO update 

The ongoing armed conflict between the Russian Federation and Ukraine presents a serious and immediate threat to the safety and security of crews and vessels operating in the region. IMO is continuing to liaise closely with all key stakeholders in the region to contribute to efforts to address the safety and security of seafarers and shipping. 

IMO Secretary-General Kitack Lim has established an Emergency Task Force to coordinate efforts to mitigate the security and safety risks to shipping, ports and seafarers.  A stranded ship reporting form has been introduced. Guidance and advice to keep Flag States appraised of the ongoing situation is updated when it becomes available.   

At the start of the conflict approximately 2000 seafarers were stranded aboard 94 vessels in Ukrainian ports. As of 20 April, 84 merchant ships remain, with nearly 500 seafarers onboard and this number continues to reduce. An estimated 1500 seafarers have so far been repatriated, manning levels have been reduced, many ships have employed local ship keepers to replace crew, and some ships have gone into cold lay-up, with no crew remaining onboard. IMO continues to carefully monitor the rapidly changing situations particularly in the ports Mariupol, Kherson, and Mykolaiv, where fighting is heaviest. 

IMO Secretary-General Kitack Lim and Guy Ryder, Director-General, International Labour Organization (ILO), have jointly written to the heads of International Committee of the Red Cross (ICRC) and Médecins Sans Frontières (MSF); and to the United Nations High Commissioner for Refugees (UNHCR), to request urgent action wherever feasible to assist in the reprovisioning of the ships concerned with the vital supplies needed by their seafarers. The letters note that, as well as the dangers arising from bombardment, many of the ships concerned now lack food, fuel, fresh water, and other vital supplies. The situation of the seafarers from many countries is becoming increasingly untenable as a result, presenting grave risks to their health and well-being. The letters note that the port city of Mariupol is currently under particularly serious attack at this time. 

As requested by the IMO Council at its 35th extraordinary session (C.ES/35), the IMO Secretary-General is collaborating with the relevant parties to initiate the establishment and support the implementation of a blue safe maritime corridor in the Black Sea and the Sea of Azov and keep Member States informed of developments. However, at present, the establishment of such a corridor is severely hampered by the ongoing security risks, which constrain the option for ships to depart from ports in Ukraine.  

The IMO Secretariat continues to work with littoral states to encourage and improve regional information sharing and promulgation of information to shipping to aid the safety of navigation and security of shipping. 

With regards to humanitarian support for maritime personnel, the IMO Secretariat has been facilitating discussions with Ukrainian ports administrations, charities and the International Labour Organization (ILO) to support port workers and seafarers directly impacted by the crisis.

IMO Meetings

Blue safe maritime corridor

The Council (C/ES.35) on 10 and 11 March agreed to encourage the establishment, as a provisional and urgent measure, of a blue safe maritime corridor to allow the safe evacuation of seafarers and ships from the high-risk and affected areas in the Black Sea and the Sea of Azov to a safe place in order to protect the life of seafarers, and ensure the mobilization and commercial navigation of vessels intending to use this corridor by avoiding military attacks and protecting and securing the maritime domain. 

The Council, in this regard, taking into account the sensitivities of the matter, invited the IMO Secretary-General to collaborate with the relevant parties and take necessary immediate actions to initiate the establishment and support the implementation of a blue safe maritime corridor in the Black Sea and the Sea of Azov and keep Member States informed of developments and report to the next session of the Council.

The IMO Secretary-General has indicated his commitment to take immediate action to realize the blue safe maritime corridor with the cooperation and collaboration of the relevant parties including littoral states.
