Developed Ship Simulation Workbench - Digital Twin for Vessel Performance. It is available to everyone through the web interface at www.SSW.mek.dtu.dk.The aim of creating the Ship Simulation Workbench is to provide the framework for the performance estimation of a ship sailing on different routes and under realistic service conditions, i.e., with waves, wind and limited water depth. Interaction between the engine and propeller is included while simulating voyages, so the estimate of the ship performance consists of, power, energy consumption, possible delays due to weather. Ship simulation workbench provides voyage performance considering all the interactions between hull, propeller, engine and weather conditions.Ship Simulation Workbench provides the flexibility to include user specified calm water resistance and propeller openwater curves. E.g., calm water resistance can be estimated using an empirical approach, model test data or CFD simulations. Hence, the industry or academic groups can continue using the methods of their preference and still be able to estimate the vessel performance using Ship Simulation Workbench.

Studied propeller efficiency, cavitation and pressure pulses in rough sea conditions in collaboration with Rolls-Royce Hydrodynamic Research Center. Explored the possibilities of improving propeller designs for better efficiency even in the presence of waves.

Involved in the project on prediction of ship emissions in different operating conditions.

Worked on the design of underwater gliders. Reviewed underwater glider designs and studied new technologies to improve gliders.
