100mph Gusts Derail Three Cranes at Guam’s Strategic Port
Three ageing Hitachi STS cranes were knocked off their rails in winds double the forecast strength.
Three ageing STS gantry cranes at the Port of Guam were derailed in a chain-reaction incident on Friday night after 100 mph gusts, double the forecast strength, dislodged the lead unit and sent it careening 1,000 feet down the quayside rail system.
military outpost. Onboard wind gauges recorded the peak gusts at 2130 hours, while forecasts had predicted a maximum of 50 mph.
Crane 6 went fully off the rails after the initial impact, while Crane 5 lost a single wheel. Crane 4 4 remained on the rail system and is considered the most viable candidate for quick restoration. The Port Authority’s experts attempted an inspection on Saturday, but persistent high winds forced a postponement until Sunday, when heavy equipment was used to separate Crane 5 from Crane 4 to create space for repair work.
The port’s strategic importance: Cranes
The three Hitachi cranes involved in the incident date back to the 1980s and were already slated for replacement under a $75 million modernisation plan. The Port Authority of Guam secured a $60 million federal Port Infrastructure Development Program grant last year, which it will match with $15 million from its own reserves to fund three newly built STS cranes. The existing cranes will be removed once the replacements are operational, while two smaller, decommissioned cranes await demolition.
The port’s strategic importance cannot be overstated: 30 % of the cargo passing through its commercial terminals supports U.S. Navy and Air Force operations. Despite the crane outage, the Port Authority has not altered its cargo schedule, as the next two inbound vessels carry ro/ro cargo, which can be offloaded without gantry cranes.
“Our immediate priority is to safely assess the condition of all three cranes and determine the steps necessary to restore operations. Our gantry crane mechanics, operations personnel and management team are mobilising early Saturday morning. We will focus our resources on safely returning available equipment to service while developing the operational plan necessary to support the upcoming vessel schedule.”

What’s next for Guam’s port recovery
Efforts to restore Crane 4 to service are now underway, with the Port Authority prioritising its return to operation to mitigate disruptions.
For now, the port’s ability to handle containerised cargo remains compromised, though the immediate impact on military logistics has been minimised due to the ro/ro nature of the next scheduled shipments.
