The Technology Centre for Offshore and Marine, Singapore (TCOMS) is a national R&D centre dedicated to the Marine & Offshore and Maritime sectors. We integrate research and industry expertise to co-create innovative concepts and solutions to address real world challenges. A core feature of TCOMS is the next-generation Deepwater Ocean Basin research facility which is equipped with advanced wave and current generation systems to simulate challenging ocean environments that marine platforms and ships operate in. TCOMS is also supported by the petascale supercomputing capabilities of the National Supercomputing Centre (NSCC) Singapore. These allow our researchers to evolve coupled numerical-physical modelling and simulation capabilities that can recreate complex operating scenarios, so as to help companies enhance the design and performance of their solutions. TCOMS is a joint venture between the Agency for Science, Technology and Research (A*STAR) and the National University of Singapore (NUS).
