Short description

The QUEST 4000m remotely operated vehicle (ROV) is a full sized, so called "workclass" deepwater ROV, originially designed to serve industrial needs for offshore production and intervention tasks. At Marum, QUEST is continuously adapted to the needs of deepsea research, utilizing its high electrical power and large payload capacity to provide a versatile platform for state-of-the-art deepwater science at water depths down to 4000 m. Today, it has proven it's value during over 30 expeditions since 2003. By December 2015, QUEST completed over 360 scientifc dives between 280 and 4014 m depth.

QUEST was originally developed as a commercial robotic vehicle by Schilling Robotics, Davis, USA, primarily for heavy duty offshore industrial applications in the deep ocean. In contrast to the commercial model, the Bremen QUEST has been adapted at Marum for a number of scientific applications.

Since it's initial deployment during expedition "M58-3" in June 2003, QUEST is routinely operated worldwide aboard research vessels between 2 to 5 times per year. Expeditions include work for several national german DFG and BMBF funded programs, internal MARUM research projects, the EU supported programmes ACES, HERMES, ESONET, the US NOAA's Ring of Fire expedition programme, and others.
