Simulation-Driven Robust Optimization of the Design of Zero Emission Vessels

The International Maritime Organization (IMO) Decarbonization Roadmap for curbing and eliminating Greenhouse Gas (GHG) emissions by 2030 2050, respectively, is a “herculean” task in its own respect. If it now combined with fundamental changes trade dynamics, volatile market conditions, tighter shipping financing platforms sustainability-linked interest rates international safety regulations setup, completely new framework commercial ship design characterized strict often contradicting requirements emerge In parallel, zero carbon fuels available (readily or the future) require extensive technological modifications technical leaps current arrangements propulsion plants (with little to no existing reference) elevated consumption figures due low energy density leading an overshoot voyage expense costs Total Cost of Ownership (TCO), respectively. Considering such tight space, holistic approaches lifecycle considerations aiming at robust designs are deemed necessary. Pursuant this roadmap, authors have developed methodology fully integrated within CAE software CAESES™ that encompass all aspects (stability, strength, powering propulsion, safety, economics) has inherent dynamic simulation module, enabling user simulate response variations geometrical, variables vessel under uncertainty. been extended model plant Ammonia powered Large Bulk carrier deployed global optimization studies utility-based ranking selection process.
