On June 14, according to the website of the Liaoning Provincial Emergency Management Department, the investigation report into the major capsizing incident involving the Huludao-based fishing vessel "Liao Sui Yu 35261" on October 18 was released. The investigation concluded that this was a major production safety liability accident. It determined the causes to be the vessel owner and captain's failure to uphold their primary responsibility for production safety, failure to deploy legally required certified crew, carrying personnel beyond the approved limit, ignoring meteorological warnings, failing to comply with recall orders, not seeking timely shelter in a port, and encountering gale-force winds during the return voyage, which led to the capsizing of the vessel.

On October 18, 2025, the "Liao Sui Yu 35261" capsized in the 27-4 fishing zone of Dalian waters during its return voyage to port, resulting in 8 fatalities and 2 missing persons. Following the incident, the Liaoning Provincial Party Committee and Provincial Government swiftly mobilized efforts, focusing all resources on search and rescue. The provincial government established an accident investigation team to conduct the investigation in accordance with laws and regulations. The Work Safety Committee of the State Council placed the investigation under its direct supervision and dispatched a steering group to the scene immediately to oversee the entire investigation process.

The investigation identified the direct cause of the accident as the vessel owner and captain's failure to seek shelter in a timely manner, choosing instead to take a longer route to replace fishing nets, and subsequently encountering severe wind and waves on the return journey. Concurrently, critical issues were highlighted, including the vessel's failure to return despite being recalled, the vessel being overloaded with insufficient certified crew, failure of the designated responsible person at the vessel's homeport to convey the recall order to the vessel in a timely manner, the perfunctory implementation of the guarantee responsibility system, a loss of control and oversight regarding vessel departures and arrivals, an inadequate joint management mechanism between the homeport and the port of call, and a failure to effectively implement local responsibilities.

In response to the problems exposed by the accident, the investigation team summarized lessons across multiple areas, including: a failure by local Party committees and governments, industry regulatory departments, and business operators to firmly establish the concept of "people first, life first"; a weak awareness of production safety on the part of the vessel owner and captain; gaps and blind spots in industry oversight by provincial, municipal, and county-level agriculture and rural affairs (marine fishery) departments; ineffective implementation of local responsibilities; and an insufficient learning of lessons from past accidents.

The vessel owner involved has been subjected to compulsory measures by judicial authorities. The Liaoning Provincial Commission for Discipline Inspection and Supervision also simultaneously established a work group for accident oversight and accountability, and has rigorously pursued accountability against 36 public officials found to bear responsibility for the incident, in accordance with regulations, discipline, and law.
