Maintenance work and weather threatens to boost Panama Canal congestion

19 May 2026

There may be claims that the Panama Canal is operating “normally”, but anxiety is increasing that forthcoming maintenance will exacerbate congestion that has built since the US and Israel launched their assault on Iran – and El Niño is on the horizon. Average waiting time at the canal has surged 60%

The Panama Canal Authority faces mounting operational pressure as maintenance schedules and the looming El Niño phenomenon threaten to disrupt global shipping lanes. Despite official claims of normal operations, average vessel waiting times have surged by 60%, complicating transit logistics for major carriers like Maersk and MSC. This congestion, compounded by geopolitical tensions impacting global trade routes, creates a bottleneck for bulk carriers and container ships attempting to navigate between the Atlantic and Pacific oceans during this critical period.

Operational compliance remains paramount under the IMO’s International Safety Management (ISM) Code, specifically regarding voyage planning and fuel efficiency protocols mandated by MARPOL Annex VI. As vessels face extended idling periods, masters must ensure strict adherence to SOLAS Chapter V, Regulation 34, which governs the safety of navigation and passage planning. Compliance departments must monitor these delays closely to mitigate risks related to hull fouling and ballast water management, ensuring that prolonged anchorage does not lead to non-conformities during Port State Control inspections.

Navigating officers and masters must prioritize precise bunker management and contingency planning to account for these unpredictable transit delays. With waiting times escalating, bridge teams should proactively optimize speed profiles to conserve fuel while maintaining strict watchkeeping standards at anchor. Clear communication with charterers regarding expected time of arrival is essential to avoid contractual disputes, requiring officers to maintain meticulous records of all delays encountered during the approach to the canal locks.
