The CEC is a self-contained patented tool which allows in-flight simulation of various atmospheric conditions during centrifuge testing. Variables that can be controlled include temperature (15 – 50°C), relative humidity (30 – 100%), solar radiation (±250 – 1550 W/m2), wind speed (0.2 – 5 m/s model) and rainfall (15 – 100 mm/hr prototype). The CEC has the unique capability of allowing independent control of the climate variables, and thus allowing for the simulation of more diverse atmospheric paths. The independent control means more fundamental studies on the influence of climate variables on geotechnical infrastructure are possible. In addition, being able to control the relative humidity allows more detailed studies on unsaturated soil behaviour. Future plans include redesigning the cooling system to simulate sub-zero temperatures for frost conditions.

The Environmental Hydrodynamic Loading System (ELHS) has the capability to model a wide range of offshore geotechnical problems, such as foundations for offshore wind farms, subsea pipelines etc. Two types of wave generators are included: 1) Piston Wave Generator for modelling shallow water coastal waves, and 2) Flap Wave Generator for modelling deep ocean waves. A frequency response exceeding 100 Hz can be simulated. This enables prototype waves having short and long periods. The maximum displacement of the plate is 10 cm. Different waveforms can be used as input (i.e. sine, cosine, square, triangular and linearly varying patterns) to generate various fluid wave types. To make the EHLS applicable to a wider range of offshore geotechnical issues, the depth of the soil layer can be varied up to maximum of 30 cm (model dimensions). Wave reflections are addressed by a passive-type wave absorbing system placed at the reflecting end of EHLS.
