A second attack in less than a month struck a liquefied natural gas tanker loaded in Qatar in the Strait of Hormuz, as QatarEnergy's force majeure deliveries have extended further and insurance premiums have climbed.

The UK Maritime Trade Operations reported that an unidentified vessel had been struck by a projectile off the coast of Oman. Security consultancies Vanguard Tech and Marisks identified the vessel as the GasLog Shanghai.

GasLog confirmed the incident occurred last Friday while the vessel was leaving the strait, and said all crew were safe and accounted for and that the tanker remained stable.

The GasLog Shanghai loaded its cargo in Qatar around last Monday and stopped transmitting its position near the strait's western entrance last Friday.

It remains unclear who owned the LNG on board. QatarEnergy did not immediately respond to questions about the cargo or whether the incident had affected shipments.
