Engineer Innovation Podcast | From Simulation to Sea Trials: the Science of Simulating Ships

In this episode of the Engineer Innovation podcast, we go behind the scenes of the world’s largest ever marine validation experiment, in which 54 teams of engineers compete to simulate the performance of a cruise ship (full of passengers). My guest is Dmitriy Ponkratov from the Royal Institution of Naval Architects who has been performing marine CFD simulations for more than two decades with Lloyds Register of Shipping and RINA, and who is a veteran of many sea trials. In this episode we discuss: ● The challenge of meeting IMO’s Zero Carbon Shipping target by 2050 ● The pivotal role that simulation plays in designing the ultra-efficient ships required to meet these standards ● Exploring novel marine propulsion systems ● Establishing trust in CFD simulation as an alternative to towing tanks and sea trials ● Creating a dataset of sea trial data that can be used to validate CFD simulations at full scale and in real world conditions ● A massive validation effort that includes 54 companies and institutions. ● How CFD engineers deal with sometimes getting the answer wrong ● The Marine Digital Twin ● Artificial Intelligence and Machine Learning as applied to the marine industry ● Conducting sea trials on a cruise ship full of gin-and-tonic sipping passengers This episode of the Engineer Innovation podcast is brought to you by Siemens Digital Industries Software — bringing electronics, engineering, and manufacturing together to build a better digital future.

They should utilize new materials and manufacturing methods and deliver new designs within ever shorter design cycles. This requires current engineering practices for product performance verification to evolve into a Digital Twin approach, which enables us to follow a more predictive process for systems-driven product development. Simcenter™ software uniquely combines system simulation, 3D CAE and tests, to help predict performance across all critical attributes, early and throughout the entire product lifecycle. By combining physics-based simulations with insights gained from data analytics, Simcenter helps you optimize design, and deliver innovations faster and with greater confidence.
