Mechanical Engineering

Mechanical engineering workshopMechanical engineers at the NOC provide engineering design, small-quantity manufacture, assembly and support for operations. Combining the use of sophisticated 2D and 3D drawing packages with their deep knowledge of what can work in the harsh marine environment, our engineers design and develop a wide range of equipment, from sub-assemblies for complex autonomous underwater vehicles (AUVs) to simple clamps for attaching instruments to frames.

The ocean is both a challenging and unforgiving environment in which to undertake scientific research. Corrosion, marine growths (biofouling), hydrostatic pressure and long-term reliability are just a few of the factors mechanical engineers at the NOC have to consider when producing their designs.

STABLE 3

STABLE 3 (Sediment Transport And Bottom Boundary Layer Experiment, version 3) is a measurements system designed for estuarine and coastal water sediment transport studies. At about 2.5m tall, and capable of carrying a large collection of instruments located over two tiers within the frame, STABLE 3 can be deployed for extended periods to support scientific fieldwork research. Typical deployments have involved month long estuarine research studies, recording sediment transport using a suite of instruments including seabed scanning sonars, water current profilers, turbidity sensors, laser-based particle sizers plus temperature, pressure and salinity sensors.

Mini-STABLE 2 Benthic Lander

Mini-STABLE 2 is the second generation of a smaller version of the STABLE 3 measurements platform and is designed to support estuarine, coastal water and shelf-seas science research. At about 2m tall it is capable of carrying a medium-large collection of instruments located over a single tier within the frame, for example, seabed scanning sonars, water current profilers, turbidity sensors and water samplers. Mini-STABLE 2 can remain deployed for several weeks and can easily be reconfigured to support the scientific research of interest.
