U.S. Coast Guard Shifts Focus to Environmental Recovery After Super Typhoon Sinlaku

Santa Rita, Guam – April 27, 2026 – With ports in Guam and the Commonwealth of the Northern Mariana Islands (CNMI) now operational, the U.S. Coast Guard has transitioned its response efforts to environmental recovery and marine safety following the devastation of Super Typhoon Sinlaku. The storm, which struck the region earlier this month, left widespread damage to maritime infrastructure, prompting a coordinated surge in recovery operations.

Ports Reopen, Commerce Resumes

The Port of Guam is now fully operational, whereas ports in the CNMI have resumed daylight operations, marking a critical milestone in the region’s recovery. The reopening of these ports has allowed the resumption of commercial activities, including the delivery of essential supplies to affected communities. The U.S. Coast Guard’s efforts to restore maritime traffic were bolstered by the deployment of vessels such as the USCGC Hickory (WLB 212), USCGC Oliver Henry (WPC 1140), and USCGC Frederick Hatch (WPC 1143), which played pivotal roles in reopening waterways and ensuring safe navigation.

“With commerce moving again, our attention turns to the waterways themselves,” said Capt. Worst, whose full statement underscored the Coast Guard’s commitment to environmental protection. “We have additional crews in Saipan this week conducting pollution assessment and response operations, and the majority of vessel owners and operators are doing the right thing — taking responsibility for their affected vessels. That cooperation makes a real difference for our communities and our environment.”

Environmental Recovery Takes Center Stage

The shift to environmental recovery reflects the Coast Guard’s dual mandate: ensuring maritime safety while protecting the region’s delicate ecosystems. Super Typhoon Sinlaku, which brought sustained winds exceeding 150 mph, caused significant damage to aids to navigation (ATON), including buoys, beacons, and other critical markers that guide vessels safely through local waterways. The USCGC Hickory crew successfully restored a key buoy in Guam and verified the positions of others before transiting to Saipan, where U.S. Navy Explosive Ordnance Disposal technicians are conducting underwater surveys to assess the extent of damage.

In Tinian, dive teams are scheduled to begin underwater ATON restoration work, a process that involves repairing or replacing damaged navigational aids to prevent accidents and ensure the safe passage of vessels. These efforts are particularly urgent given the region’s reliance on maritime trade, and tourism.

Vessel Recovery and Pollution Mitigation

One of the most pressing challenges in the aftermath of the typhoon has been the recovery of damaged or sunken vessels. In Guam, initial assessments identified multiple casualties, including barges, mobile crane barges, and a derelict vessel that broke free from commercial piers and grounded in the Piti Channel. The dry dock at Cabras also partially submerged near Pier F3, along with the tugboat Polaris, which was successfully refloated by salvage teams.

“We are aware and engaged on all vessel casualties related to the storm,” said a Coast Guard spokesperson. “Our teams are actively monitoring the situation to ensure a swift and effective response.” The sailboat Pros remains the only confirmed sunken vessel, with its owner issued a captain of the port order to submit a salvage plan or face federal intervention.

Pollution response has been a key focus, with the Coast Guard working closely with port partners to mitigate environmental risks. The cooperation between federal agencies, local authorities, and private salvage companies has been critical in addressing potential hazards, such as fuel leaks or debris that could harm marine life.

Ongoing Challenges: Communications and Infrastructure

While progress has been made, degraded communications infrastructure continues to pose challenges for recovery efforts. In some areas, particularly in the CNMI, limited connectivity has slowed the coordination of relief operations. The Coast Guard has prioritized restoring communication networks to facilitate real-time updates and ensure the safety of responders and residents alike.

“This is a marathon, not a sprint,” said a Coast Guard official. “We’re making steady progress, but there’s still work to be done to fully restore the region’s maritime infrastructure.”

Key Takeaways

• Ports Reopen: The Port of Guam is fully operational, while CNMI ports are open for daylight operations, allowing the resumption of commercial activities.
• Environmental Focus: The Coast Guard has shifted its efforts to pollution assessment and response, with crews deployed in Saipan and Tinian.
• Vessel Recovery: Multiple vessels, including barges and the tugboat Polaris, were damaged or grounded during the storm. Salvage operations are underway.
• ATON Restoration: Dive teams are working to repair or replace damaged navigational aids to ensure safe maritime traffic.
• Communication Challenges: Degraded infrastructure remains a hurdle, with efforts ongoing to restore connectivity in affected areas.

Looking Ahead

As the U.S. Coast Guard continues its recovery efforts, the focus will remain on balancing the immediate needs of affected communities with long-term environmental protection. The cooperation between federal agencies, local governments, and private sector partners will be crucial in ensuring a full and sustainable recovery for Guam and the CNMI. With ports reopening and commerce resuming, the region is taking critical steps toward normalcy, but the road to full recovery is still unfolding.
