Sonar imagery of the vessel suspected to be the sunken ferry MV Princess Ashika has been released as Australian Navy divers complete their commitment to OP Ashika Assist. The imagery from the Royal New Zealand Navy’s REMUS (Remote Environment Measuring Underwater System) detachment revealed a vessel on the ocean floor with dimensions matching those of the ferry which sank in waters SSW of Nomuka in the Ha’apai group of islands.

HMNZS Manawanui is due to arrive in Tonga on Saturday 15 August, and will provide a platform from which to launch the ROV. The RNZN Operational Dive Team regularly uses the HMNZS Manawanui as a dive platform. The vessel uses a four point mooring system and can anchor in the 110m of water surrounding the sunken vessel.

Meanwhile divers of AUSCDT ONE packed the equipment they deployed to Tonga at His Majesty’s Naval Base Masefield (Touliki). Earlier in the week AUSCDT ONE divers established that the floating mooring line attached to the MV Princess Ashika extended beyond the deployed diving capabilities of both AUSCDT ONE and ODT. The divers from both teams battled rough seas aboard the Tongan patrol boat VOEA Pangai.”

This follows an announcement on Wednesday that the joint Tongan, Australian and New Zealand naval task force assigned to search for and, if possible, recover bodies from the vessel had identified its location.

Sonar Imagery from the Royal New Zealand Navy’s REMUS (Remote Environment Measuring Underwater System) detachment revealed a vessel on the ocean floor with dimensions matching those of the ferry which sank in waters South West of Nomuka in the Ha’apai group of islands. The vessel is sitting in 110m of water, and has a bow section, bridge, passenger accommodation and cargo bays matching those of the MV Princess Ashika. At a depth of 110m, the vessel is beyond the capability of the Clearance Dive Team. They will now return to their base at HMAS Waterhen.
