AMSA Detains Liberian-Flagged Vessel After 24-Day Coral Sea Emergency Near Great Barrier Reef

Australia’s maritime safety regulator has detained a Liberian-flagged vessel after completing a 24-day emergency response operation in the Coral Sea.

The operation prevented potential environmental and navigational risks near the Great Barrier Reef, one of the world’s most sensitive marine ecosystems.

The vessel, Swift Hangzhou, suffered engine failure on 1 February 2026, prompting an immediate response from the Australian Maritime Safety Authority (AMSA).

After nearly three weeks of coordinated efforts, the ship is now safely anchored in Gladstone, Queensland.

On 1 February 2026, AMSA received reports that the Liberian-flagged Swift Hangzhou had experienced engine failure while operating in the Coral Sea off Queensland.

Given the vessel’s proximity to the Great Barrier Reef and surrounding marine park, authorities assessed the situation as high risk. A drifting vessel in the region could pose serious danger to coral ecosystems, shipping lanes, and crew safety.

AMSA activated emergency response arrangements immediately. The operation lasted 24 days due to the technical complexity of the engine failure and prevailing weather conditions.

During the response, AMSA deployed multiple tugs to prevent the vessel from drifting into sensitive areas of the Great Barrier Reef and adjacent marine park zones.

A Maritime Casualty Officer was dispatched onboard to inspect the engine failure and provide technical guidance. The officer worked directly with the vessel’s captain and AMSA’s response teams to assess seaworthiness and manage onboard risks.

Authorities maintained round-the-clock monitoring of the ship’s position and weather conditions to ensure the vessel remained clear of protected reef systems.

The response was carried out in coordination with Queensland authorities, including Maritime Safety Queensland and agencies responsible for managing the Great Barrier Reef Marine Park.

Continuous communication was maintained between AMSA, the vessel’s master, and the ship’s operating company. Officials confirmed that stakeholder engagement supported safe decision-making throughout the operation.

Crew welfare was monitored daily. AMSA conducted regular checks with the captain to ensure adequate provisions and support for seafarers during the extended response period.

As of 24 February 2026, Swift Hangzhou is safely anchored in Gladstone, Queensland. Following inspection, AMSA has formally detained the vessel on seaworthiness grounds.

Detention means the vessel cannot depart until identified deficiencies are addressed and authorities are satisfied that it meets safety standards.

AMSA Executive Director Response, Alex Barrell, stated that maritime incidents can occur at any stage of a voyage. He noted that AMSA’s management of the engine failure reduced risk to the vessel, crew, and marine environment. He also acknowledged the contribution of AMSA personnel and stakeholders involved in the operation.
