On February 12, 2026, the Shanghai Municipal Government released the findings of its investigation into a fatal confined-space accident that occurred on September 4, 2025, aboard the Very Large Ethane Carrier (VLEC) H2648, later named PACIFIC INEOS MIO. The accident, which happened during final outfitting and commissioning at Jiangnan Shipyard, resulted in three worker fatalities due to asphyxiation when nitrogen entered a cargo hold through a partially open isolation valve. The official report cites multiple safety lapses, including the absence of a confined space entry permit, lack of ventilation and oxygen testing, and insufficient supervision. Accountability measures include criminal referral for two individuals, disciplinary action for management, and administrative penalties for the shipyard and its leadership. The vessel was being constructed for Shandong Marine Energy and is intended to serve INEOS in global ethane transportation.
