At 0029 local time on April 18, 2017, while transiting northbound through the Panama Canal, the Panama-flagged tugboat Cerro Santiago collided with the US Coast Guard cutter Tampa in Miraflores Lake, Panama. Although the tugboat was not damaged, the cutter sustained $170,018 in damage to the stern as well as to various systems in the steering gear room. There were no injuries, nor was there any report of pollution.
The probable cause of the collision between the tugboat Cerro Santiago and the US Coast Guard cutter Tampa was the failure of the master of the Cerro Santiago to maintain a vigilant watch due to fatigue.
