The Portugal Maritime Police are investigating the unexplained disappearance of a 49-year-old merchant marine officer who vanished from a cargo vessel sailing between the Azores and the mainland—a case that has highlighted existing safety challenges facing maritime workers in Portuguese waters and raised questions about surveillance gaps aboard commercial ships.
Why This Matters
• No conclusive evidence: César Daniel Gomes disappeared sometime in May 2025 during a routine voyage from Ponta Delgada to Leixões. Despite extensive searches at sea and on the vessel, no trace of him has been found.
• Limited monitoring: The area near his cabin had no CCTV coverage, forcing investigators to rely on crew interviews, mobile phone data, and ship logs to reconstruct events.
• Regulatory gaps: Portugal's maritime safety regulations do not mandate comprehensive CCTV coverage in all exterior crew areas aboard cargo vessels, a gap that complicates incident reconstruction when accidents occur outside working hours.
What Happened Aboard the ETE Portugal
César Daniel Gomes, a logistics officer from Lisbon, boarded the ETE Portugal cargo ship in Ponta Delgada in May 2025. His job was shore-based coordination—he was not scheduled for night or early-morning shifts. Colleagues noticed his absence in the early hours after May 6, while the vessel was still at sea, and immediately alerted the ship's second officer, who launched searches from the deck. Nothing was found.
When the ETE Portugal docked at Leixões days later, the Portugal Maritime Police deployed sniffer dogs from the Guarda Nacional Republicana (GNR) and the Polícia de Segurança Pública (PSP), along with an investigator from the Polícia Judiciária (PJ), to sweep the ship. They combed through storage areas, machinery rooms, and crew quarters. Still no sign of Gomes.
The Most Probable Scenario
According to investigators familiar with the case, the leading theory is that Gomes fell overboard during his time aboard. Crew members reported that he would occasionally step out onto the open deck near his cabin to "get some air." The deck in question—essentially a balcony area—lacked a railing, relying instead on a single protective chain. He was last described wearing slippers, not work boots, suggesting an informal, off-duty moment.
The absence of video surveillance in that section of the ship has proven a significant obstacle. Portuguese maritime safety regulations do not mandate CCTV coverage in all exterior crew areas aboard cargo vessels, a gap that complicates incident reconstruction when accidents occur outside working hours.
No Conflicts, No Warnings
Interviews with the ETE Portugal's crew yielded no evidence of workplace disputes, arguments, or tension involving Gomes. Colleagues described him as competent and reserved. His social media presence painted a picture of a passionate Sporting CP supporter and a career mariner proud of his work—his Facebook page featured numerous photographs of ships and sea routes. He is survived by a minor son.
Gomes held a pilotage qualification but was assigned to logistics, meaning his role centered on cargo planning and port coordination rather than bridge watches. His shift schedule did not require nighttime duty, making his presence on an exterior deck in informal hours consistent with personal routine rather than work obligation.
Investigation Continues with Limited Leads
The Portugal Maritime Police continue to treat all scenarios as open. Investigators are analyzing Gomes's mobile phone, personal computer, and the ship's logbook entries to establish a clearer timeline. Standard protocols dictate that maritime disappearances are investigated as potential accidents unless evidence suggests otherwise, and so far, nothing points to foul play.
Portuguese maritime law requires that all accidents aboard commercial vessels be reported to the Direção-Geral da Autoridade Marítima (DGAM), which coordinates with the Marinha Portuguesa on search-and-rescue operations. In this case, the initial search covered several square nautical miles around the presumed last known position, but rough Atlantic conditions and reporting delays reduced the likelihood of recovery.
What This Means for Maritime Workers
This incident highlights persistent safety vulnerabilities in the Portugal merchant marine fleet. While the International Convention for the Safety of Life at Sea (SOLAS) and the ISM Code mandate safety management systems aboard Portuguese-flagged vessels, enforcement of crew protection measures in non-operational areas remains inconsistent.
Current regulations require:
• Secure access systems for boarding and disembarking, including railings and safety nets.
• Personal protective equipment (PPE) for crew working on deck, including life jackets and harnesses for elevated positions.
• Incident reporting within 24 hours of any accident or disappearance.
However, informal rest areas—like the balcony near Gomes's cabin—often fall into a regulatory gray zone. They are not classified as "working zones," so the same stringent safety barriers do not apply. The Federação Portuguesa de Nadadores Salvadores (FEPONS) has called for stronger national guidelines on crew welfare spaces, arguing that protective measures should extend beyond operational hours.
A Troubling Year for Water-Related Disappearances
Gomes's case reflects broader concerns in Portugal's maritime sector. As of the end of May, 57 people had drowned in Portugal—virtually identical to the same period in 2024, which was among the worst on record in recent years according to FEPONS. While the majority of drownings occur in coastal leisure areas, maritime workers face distinct risks tied to vessel design, long shifts, and isolation.
Persistent Gaps in Offshore Monitoring
Unlike passenger ferries, which are heavily regulated for CCTV and real-time tracking, cargo vessels like the ETE Portugal operate with far less oversight once they leave port. The Portugal Maritime Police have limited jurisdiction over foreign-flagged ships transiting Portuguese waters, and even domestic vessels are not required to install comprehensive video surveillance systems unless carrying hazardous cargo.
The DGAM has proposed expanding mandatory surveillance coverage to include crew quarters and rest areas on all Portuguese-flagged commercial ships, but the measure has faced delays due to cost concerns from ship operators. Industry groups argue that retrofitting existing vessels with modern monitoring systems could represent a significant expense for smaller freight companies already operating on thin margins.
Lessons and Reforms
The FEPONS has announced plans to request meetings with government officials to present concrete proposals aimed at reducing water-related deaths, including stricter enforcement of safety protocols aboard commercial vessels. Advocacy groups are calling for:
• Mandatory CCTV coverage in all exterior crew areas on ships over 500 gross tonnes.
• Automatic man-overboard alarms using wearable devices that trigger alerts if a crew member falls into the water.
• Regular safety audits of non-operational spaces, including balconies, recreation areas, and exterior walkways.
For now, the family of César Daniel Gomes waits for answers. The Portugal Maritime Police have not ruled out any investigative lines, but without physical evidence or eyewitnesses, the case may remain unresolved indefinitely. Investigators say the outcome will depend largely on what, if anything, can be retrieved from Gomes's electronic devices and whether ship logs reveal any overlooked details from the time at sea.
