The Challenge is a versatile multi-purpose vessel and is used as a dive support platform, for ADCP deployment and recovery and for people transport. In addition to this it is used for harbour maintenance and support for the larger vessels. One of the characteristics of this vessel is that plant and equipment can be driven onto the vessel and off loaded to larger vessels when on site.
