Test tank

JFD's outdoor water tank is suitable for the testing of a wide variety of subsea applications including the deployment of ROVs, manned air diving trials and ancillary subsea equipment.

With a depth of 8 metres and a diameter of 12 metres, the 900,000 litre steel tank is ideal for testing equipment and large enough to accommodate the deployment and operation of work class ROVs, air diving systems and ancillary equipment.

The tank is fully equipped to provide a safe and controlled diving environment - perfect for manned trials.


The Test Tank has an open walkway around the top of the tank - ideal for viewing operations. Adjoined is a working platform capable of accepting modules such as control cabins and deployment systems.

In-water activity can be monitored via view-ports which are situated at ground level around the base of the facility. Alternatively, video can be displayed on monitors within the National Hyperbaric Centre complex.

The tank is complete with a 3 diver capability air diving control system, with full diver communications and real-time video display/recording for manned diving operations.

A variety of structural component replicas can be provided to simulate realistic working environments for testing and performance trials.
