Salvage Effort Hampered by Rough Seas After San Juan Barge Grounding

High surf is delaying efforts to refloat a grounded tank barge at the entrance to San Juan Harbor in Puerto Rico, as responders wait for safer weather to begin full salvage operations.

Grounded barge blocks rocky approach to San Juan Harbor

A 265 foot fuel barge ran aground near the harbor entrance after losing control while inbound from St. Thomas in the U.S. Virgin Islands. The vessel came to rest on a rocky section close to the historic headland west of the main navigation channel. Persistent wave action forced the barge into a narrow gap between coastal rock structures, where it remains exposed to heavy surf.

The location presents operational challenges for salvage crews. Strong seas continue to pound the hull, limiting safe access for tugs and response craft. Authorities report wave heights of up to 15 feet in the area, conditions that prevent close quarters maneuvering and refloating attempts.

Coast Guard coordinates incident response

The U.S. Coast Guard Sector San Juan established an incident management team to coordinate the response with local emergency agencies and salvage specialists. A coastal advisory remains in effect, and officials expect meaningful recovery work to begin only after sea conditions moderate.

Initial on site assessments detected a diesel odor, raising concern about a possible fuel release. Responders have not confirmed any visible sheen on the water. Detection remains difficult under current surf conditions, and monitoring continues as a precaution.

Limited fuel onboard reduces pollution risk

Preliminary reports indicate the barge was largely empty at the time of the grounding. It may contain about 1,000 gallons of residual light diesel following a recent cargo discharge. A separate small tank used for onboard equipment also holds a limited volume of fuel.

Salvage planners intend to tow the vessel clear of the rocks once weather allows. San Juan Harbor remains open to commercial traffic, although a safety zone surrounds the incident site. No injuries have been reported. Authorities continue to investigate the cause of the grounding while maintaining environmental safeguards.
