IMO Moves to Open Safe Maritime Corridor as 3,200 Vessels, 20,000 Seafarers Remain Trapped in Gulf Crisis
IMO Moves to Open Safe Maritime Corridor as 3,200 Vessels, 20,000 Seafarers Remain Trapped in Gulf Crisis

The International Maritime Organization (IMO) has approved plans for a “safe maritime corridor” to evacuate thousands of commercial vessels stranded in the Gulf region as the security crisis around the Strait of Hormuz deepens, with significant implications for Nigerian and West African shipping.
The proposal, endorsed at an extraordinary session of the IMO Council in London on March 18–19, is designed as a voluntary, non-military framework to allow stranded vessels to exit high-risk areas in an organised and coordinated manner. Bahrain put forward the initiative, which member states accepted as an urgent interim measure to address one of the gravest threats to global maritime trade in recent memory.
IMO Secretary-General Arsenio Dominguez has been mandated to engage governments and industry stakeholders to bring the plan into operation, underscoring the urgency with which the international maritime community is treating the situation.
Scale of the Crisis
The human and commercial stakes are considerable. IMO figures put the number of vessels currently trapped in the Gulf at approximately 3,200, carrying around 20,000 seafarers. Crews face heightened security risks, mounting operational disruptions and increasing physical fatigue as tensions in the region show no sign of abating.
Shipping traffic through the Strait of Hormuz — a chokepoint through which roughly 20 percent of the world’s oil supply flows — has already fallen sharply. Persistent attacks involving missiles, drones and sea mines have driven up war-risk insurance premiums to prohibitive levels and deterred vessel operators from transiting the route.
Western Powers Issue Joint Condemnation
Diplomatic pressure on Iran is intensifying. In a joint statement released on March 19, leaders of the United Kingdom, France, Germany, Italy, the Netherlands and Japan condemned ongoing attacks on commercial shipping and energy infrastructure, attributing the disruption directly to Iran and describing the situation as a de facto closure of the strait.
The six nations called on Iran to halt hostile activities — including mine-laying and missile and drone strikes — and reaffirmed the principle of freedom of navigation under international law. They indicated readiness to support efforts to restore safe passage but stopped short of committing to naval escorts or specific security deployments.
Military Option Stalls
Proposals for a military-backed escort system have run into resistance. Key allies of the United States — including Germany, Spain and Italy — have declined to deploy naval forces, citing the absence of a mandate from the United Nations, the European Union or NATO, as well as inadequate prior consultation on the proposal.
The reluctance of Western governments to pursue a military solution has reinforced the IMO’s preference for a civilian-led, non-militarized approach. The proposed corridor would provide a structured exit pathway for trapped vessels without dependence on armed escorts.
Comparison to Black Sea Grain Initiative
Analysts have drawn parallels between the proposed corridor and the Black Sea Grain Initiative, which established a protected shipping route during the Ukraine conflict. However, a key distinction exists: that arrangement rested on guarantees provided by the United Nations and Turkey, whereas the IMO is expected to assume a more direct coordinating role in the Hormuz framework.
Whether the organisation can operationalise such a mechanism within an active conflict zone remains a live question, and several IMO member states have already raised concerns about the practical feasibility of the plan.
Nigeria Watch
The Hormuz corridor proposal arrives at a critical juncture for Nigerian maritime interests.
Nigeria’s economy is tied to global oil markets, and any sustained disruption to energy flows through the Strait of Hormuz feeds directly into crude price volatility, freight rate increases and supply chain uncertainty — all of which affect the cost of imports arriving at Apapa and Tin Can Island ports.
The crisis also has a human dimension for Nigeria. The country has an active seafarer community with Nigerian nationals serving aboard vessels operating in Gulf waters. The welfare of approximately 20,000 seafarers currently stranded in the region — some of whom may be Nigerian — is a matter of direct concern for the Nigerian Maritime Administration and Safety Agency (NIMASA) and the Maritime Workers Union of Nigeria (MWUN).
Operationally, Nigerian shipping stakeholders will be watching the fate of the IMO corridor proposal closely. With major carriers already activating emergency multimodal rerouting — as seen with CMA CGM’s recent announcement of alternative corridors via the Red Sea and overland routes — Nigerian importers and exporters could face extended transit times and revised freight schedules into the second quarter of 2026.
The IMO’s credibility in crisis management is also under scrutiny. If the corridor succeeds, it would represent a landmark use of civilian multilateral coordination to manage a live maritime emergency — a model with potential implications for security architecture in the Gulf of Guinea, where Nigeria has long advocated for non-militarized regional maritime cooperation.
