On the morning of 7 January 2026, a routine Irish Sea crossing turned into a critical maritime emergency when the roll-on/roll-off passenger (RoPax) ferry Stena Estrid collided with port infrastructure during berthing operations at Holyhead, Wales. Operating its regular scheduled route from Dublin, Ireland, the 214-meter-long vessel made heavy contact with an unprotected turning fender situated at the northern extent of Terminal 3. The impact breached the ship’s steel hull both below the waterline—causing a severe ingress of seawater into the starboard engine room—and above the waterline on the cargo deck.
The incident transformed a standard commuter and freight transit into a serious marine casualty, testing the crisis response capabilities of both the shipboard crew and shore-based management. Thanks to swift, disciplined intervention by the onboard engineering and deck teams, catastrophic flooding was averted. Crew members successfully shored up internal bulkheads, pumped out thousands of gallons of water, and intentionally shifted the vessel’s ballast to induce a port list, effectively elevating the starboard hull breach above the waterline.
Despite the alarming nature of the collision and the subsequent flooding of approximately 500 tonnes of water into critical engineering spaces, no injuries or fatalities were reported among the 157 people on board. The vessel safely completed its berthing maneuver, allowing passengers and vehicle drivers to disembark without significant delay.
Following a preliminary assessment (PA Summary 3/2026) conducted by the Marine Accident Investigation Branch (MAIB), investigators have opted to close the formal inquiry. This decision was reached in light of proactive safety actions, operational reviews, and planned port infrastructure enhancements undertaken by Stena Line Limited and Stena Line Ports Limited. This comprehensive report explores the chronology of the incident, evaluates the vessel and voyage metrics, details the damage control efforts, and examines the broader implications for ferry operations across the Irish Sea.
Detailed Chronology
Approach and Maneuvering at Holyhead Port
At approximately 0750 UTC on 7 January 2026, the Stena Estrid approached the final stages of its international voyage from Dublin to Holyhead. Weather conditions in the area were testing, with a strong westerly wind blowing at Force 6 to 7, presenting significant crosswind pressures as the large vessel prepared to maneuver within the constrained confines of the Welsh port.
Prior to executing the stern-first backing maneuver required to secure the vessel at Terminal 3, the bridge team initiated a port turn just north of the facility’s jetty. To assist with heading control and positioning against the strong westerly gusts, a harbour tug had been made fast to the ferry’s port aft quarter.
As the maneuver progressed, the combined hydrodynamic forces, environmental pressures, and turning dynamics brought the starboard side of the vessel into forceful contact with the northern extent of Terminal 3. Specifically, the ship struck an unprotected turning fender, a structural point that proved unforgiving to the incoming hull.
The Impact and Immediate Structural Failure
The kinetic energy of the collision resulted in immediate structural damage. The point of impact punched a hole through the heavy steel hullplates in two distinct locations:
- Below the waterline: A breach directly opened into the starboard engine room, allowing an unchecked torrent of seawater to rush into the compartment.
- Above the waterline: A secondary structural puncture occurred higher up on the vessel’s cargo deck, though this area remained free from direct water ingress.
Within minutes, approximately 500 tonnes of seawater flooded the starboard engine room. Simultaneously, an undetermined quantity of water found its way into an adjacent internal void space, compromising the vessel’s trim and stability reserves.
Crisis Management and Damage Control
Onboard emergencies of this magnitude demand absolute precision and instant execution from the ship’s complement. With 91 passengers, 66 crew members, and 95 vehicles on board, the stakes could not have been higher.
The engineering and deck departments immediately mobilized under the ship’s emergency response protocols. Recognizing the gravity of the starboard flooding, the crew executed a multi-pronged damage control strategy:
- Shoring Up the Hull: Engineering teams deployed rapid-response shoring materials to reinforce the weakened and breached hull plating below the waterline, successfully mitigating the rate of further water ingress.
- Dewatering Operations: High-capacity emergency bilge pumps were brought online to expel water from the flooded starboard engine room, stabilizing internal fluid levels.
- Ballast Manipulation: In a critical display of seamanship, the master and chief officer ordered the deliberate transfer of internal ballast water. By shifting weight across the vessel’s beam, they induced a deliberate port list. This intentional tilt raised the damaged starboard section of the hull above the waterline, effectively halting any further hydrostatic pressure and water entry.
Berthing, Disembarkation, and Port Closure
With the ship stabilized and the internal flooding brought completely under control, the master assessed that it was safe to resume the berthing operation. The Stena Estrid successfully docked at Terminal 3, and the ramp was lowered.
Passengers and vehicle drivers were safely unloaded without significant delay, blissfully unaware of the profound mechanical crisis unfolding just bulkheads away. Following the completion of disembarkation, Holyhead Port authorities implemented a temporary closure to all incoming and outgoing ferry traffic.
Later that evening, once the Stena Estrid was safely shifted to an alternate berth, marine surveyors conducted an exhaustive damage assessment of the Terminal 3 jetty. Finding no structural deficiencies or significant damage to the port infrastructure, authorities cleared the terminal for a return to service.
Following temporary steel patches and structural reinforcements applied at Holyhead, the Stena Estrid cast off and traveled under its own power across the Irish Sea to a specialized dry dock facility in Liverpool, England, for permanent repairs.
