ROV PHOCA is a remotely operated underwater vehicle of the COMANCHE type. It was built by sub-Atlantic, Aberdeen, Scotland and is owned by the GEOMAR - Helmholtz Centre for Ocean Research Kiel. Its smaller size compared to the ROV KIEL 6000 and therefore its deploy ability from medium-sized research vessels makes it a complement to the QUEST type ROV. It can dive up to 3000m (9842.52 feet) and was designed as a Work-Class- and Intervention-ROV.
It is characterized by these features:
ROV PHOCA's main employment will be the installation and maintenance of the deep sea observatory MoLab, but also within other multi-disciplinary projects such as projects by the Cluster of Excellence "The Future Ocean".[1]
