Consulting to industry
CMST has provided consulting to industry since 1985. Three modes are available:
• Fast-turnaround, commercial-in-confidence consulting
• Accessing state and national government research programs
• Supervising student research projects (undergraduate and postgraduate)

Short courses to industry
Tailored courses to industry staff, e.g.:
• Ship motions in waves (5 day course to DSTO, May 2012)
• Stability and seakeeping refresher (1/2 day course to Fugro-TSM, May 2012)
Curtin undergrad units:
• Design for Small Craft (online course from June 2013)
