Nova Star diverted back to Gdańsk after fuel system failure

The Nova Star ro-pax ferry operating on the Gdańsk–Nynäshamn route for Polferries was forced to abandon its Saturday sailing after a malfunction occurred in one of its four main engines. The incident took place roughly two hours into the voyage, off the Hel Peninsula. According to the operator, a failure in a high-pressure component of the fuel supply system prompted the decision to return to Gdańsk for inspection and repairs.

A total of 115 passengers were on board. Although the vessel retained manoeuvrability, the master requested tug assistance as a precaution – a standard measure when propulsion redundancy is partially reduced. Upon return to port, Polferries offered passengers rebooking options or full refunds, while those staying aboard were provided with accommodation and meals during the delay.

Nature of the failure

Initial assessments indicate a malfunction in a high-pressure fuel system component of one main engine. Failures of this type require detailed diagnostics due to the precision tolerances of injection systems and the risk of secondary damage if operation continues under abnormal conditions. Returning to Gdańsk ensured access to appropriate technical support and spare parts.

Tug assistance and port operation

The swift response of the Port of Gdańsk played a key role in the safe return of the vessel. Two harbour tugs were deployed to meet Nova Star in the approaches and escort the ferry to its berth. Even though the vessel remained manoeuvrable, tug support significantly increased the safety margin during the approach and final turning phases. Coordination between the bridge team, tug crews and the Harbour Master’s Office enabled a stable, controlled and incident-free berthing.

Next steps for the operator

Polferries has initiated a full inspection of the affected engine’s fuel system and complementary checks on the remaining propulsion units. The ferry will resume regular operations once the necessary repairs are completed and full operational readiness is confirmed.
