Anuanua Moana

Anuanua Moana ("Rainbow of the Sea") is a research vessel registered in the Cook Islands. It is operated by Moana Minerals and used for conducting surveys for Deep sea mining.

The ship was previously known as the VOS Satisfaction and previously operated as a subsea support vessel to support underwater diving- and ROV-operations as well as some salvage projects. In 2022 it was modified to provide space for scientists as well as lifting and sonar gear.

The ship arrived in the Cook Islands in February 2023. It was named in March 2023 after a public competition. It began its first survey expedition in March 2023. Cook Islands Prime Minister Mark Brown accompanied the ship for the first stage of its voyage, mapping the seabed from Rarotonga to the Nga-Pu-Toru before docking in Aitutaki.

In November 2023 it began an expedition to explore the seabed between Rarotonga and Aitutaki.
