Technical Detail

General Information:

ROV MARUM-Squid is a SAAB-Seaeye Leopard type compact, small work-class ROV system for operations down to 2000 m water depth, designed to operate from small research vessels with limited deck space.

The vehicle has the possibility to maintain position in the water column (midwater station-keeping) without acoustic link to the seafloor via DVL or similar. The advanced sensor package also allows accurate track following necessary to perform e.g. photo-mosaicking tasks.

Vessel Requirements:

Suitable for smaller vessels with limited deck space. The waiving of an additional 20″ control container results in a very small footprint of <10m² for winch and ROV on deck, making the system well suited for operations from small platforms.


The above-average thruster power (>3 knots forward speed) allows operations in high current areas, denied to systems with comparably lower thruster-power.


HD video camera, 14 megapixel stills, PAL overview camera

1 pair of green line lasers, Videorecording on hard-disk.

Positioning (USBL, etc):

For positioning, ROV-Squid uses the Posidonia or GAPS USBL systems from IXBLUE.  Due to the advanced navigational sensor package of the ROV, positioning and displacement within 10cm is possible. The system can fly along given patterns within this accuracy to create photo-mosaics on small scale structures such as bacterial mats.

Station-keeping in the water column is also possible which can be of interest to scientists studying midwater biota. The vehicle can maintain its position, acting as a stable, non-drifting platform anywhere between the surface and the seafloor.


Attitude heading and reference unit (laser gyro, 3-axis accelerometers, DVL), Dual frequency sonar; 325/675kHz, Depth sensor, Altimeter, Magnetic compass, CTD Probe.

Optional Items:

Free interfaces for additional scientific sensors: 2 x serial links (RS232), 1 x Gigabit Ethernet port, 1 x PAL cam


Seven function manipulator, Sample drawer-box for sample storage and payload installation. 


The vehicle is a free-flyer without TMS or LARS to be deployed over the side of the vessel via the ship´s crane.

Modality of Access

A successful TNA proposal will be integrated into the cruise planning process of the system. Within this process, the cruise is scheduled and allocated to a suitable time slot. Part of the planning process is to evaluate whether the system can operate from the proposed vessel, taking into account e.g. lifting gear, positioning possibilities or lab space. Hence, a visit to the ship within the scope of the cruise preparation is eligible in order to prepare mobilization and operation. A pre-cruise meeting with the responsible scientists will be organized to discuss details of the cruise, operation and payload.

A detailed description of the desired payload to be integrated to the system needs to be provided by the user. The payload is to be sent to MARUM early enough for integration and testing.

Mob/Demob in port requires 2 days by the ROV team which consists of 4 Pilots/Technicians.

Shipping and logistics of the system will be organized by the MARUM logistics department and costs covered by Eurofleets+ up to a maximum amount.  Users should contact prior to submitting an application to ensure shipment costs from their location are covered.

Support Offered to EurofleetsPlus Users

MARUM-Squid will be operated by a trained crew with a long-term experience in ROV operation. The team will assist and support the scientific party in any ROV related matters like technical or operational issues. The team will take care of the mobilization/demobilization on the vessel with support from the ship´s crew, operation and repairs. Dives are possible on a daily basis but are limited to 8 hours operation time, however exceptions can be made depending on the current situation.

With support from the ROV team, the scientists are asked to prepare a scientific dive plan for each dive to use the system as efficiently as possible.
