Ocean Infinity locates Stellar Daisy

Ocean Infinity, the next generation seabed survey and ocean exploration company, has successfully
located the wreck of the lost South Korean tanker, Stellar Daisy, at a depth of 3461 meter in the South Atlantic Ocean, approximately 1800 nautical miles due west of Cape Town.

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

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.”
