Stellar Daisy sank on 31 March 2017, transporting iron ore from Brazil to China. Tragically, 22 of the 24 crew were lost.
Working from Seabed Constructor, the search operation involved the deployment of four Autonomous Underwater Vehicles (AUVs), which, over 72 search hours, explored approximately 1,300 km2 of seabed. Representatives of both The Government of South Korea, who awarded Ocean Infinity the contract to conduct the search, and the families of Stellar Daisy’s crew, were present throughout the operation.
Ocean Infinity’s AUVs are the most technologically advanced in the world. They are capable of operating in water depths from 5 meters to 6,000 meters. The AUVs are not tethered to the vessel during operations, allowing them to go deeper and collect higher quality data for the search. They are equipped with a side scan sonar, a multi-beam echo-sounder, a sub-bottom profiler, an HD camera, a conductivity / temperature / depth sensor, a self-compensating magnetometer, a synthetic aperture sonar and a turbidity sensor.
Oliver Plunkett, Ocean Infinity’s CEO, said:
“We are pleased to report that we have located Stellar Daisy, in particular for our client, the South Korean Government, but also for the families of those who lost loved ones in this tragedy. This operation is further testament to Ocean Infinity’s leading, technology led, search capability. Through the deployment of multiple state of the art AUVs, we are covering the seabed with unprecedented speed and accuracy. I would like to thank the Government of South Korea for their support, as well as all of the team onboard Seabed Constructor.”
