Oceanlab has a substantial indoor fresh water tank capable of accommodating offshore assemblies for testing. The tank has dimensions of 5 x 5 x 5 metres and is an essential proving facility for subsea inspection equipment, ROVs and other subsea test simulations.

A saltwater tank with acoustically neutral walls is also available for calibration and testing of sonar transducers and can be used to establish whether equipment is suitable for use in high corrosion environments.
