About CMST

• Founded in 1985

• Research Centre within Curtin University

• Bentley & Fremantle


CMST research areas

• Hydrodynamics

• Marine acoustics

• Underwater technology


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)


Hydrodynamics

• Ship motions in waves

• Under-keel clearance

• Forces on moored vessels

• Resistance and wake

• General flow calculations


Ship motions in waves

• Maxsurf, SEAWAY and WAMIT

• Full-scale validation trials


Hull slamming

• Smoothed Particle Hydrodynamics (SPH)


Under-keel clearance

• Squat tables and UKC software

• Dredging depth optimization


Forces on moored vessels

• Design loads for mooring systems

• Diagnosing mooring line breakages


Resistance and wake
