Independent ship classification society Indian Register of Shipping (IRS) has selected MSC Software’s Dytran simulator to combat underwater explosion (UNDEX) threats.

Dytran explicit non-linear simulation solution is said to help predict responses of ship structures when subjected to explosions.

The need to design and analyse such events comes in the wake of growing threats, such as low and high-intensity underwater explosions, to both naval and commercial vessels in the international waters.

UNDEX events, such as shock wave formation, gas bubble oscillation, bubble migration and collapse of gas bubble-forming water jet, cannot be practically tested to analyse the catastrophic consequences on ship structures, according to MSC Software.

"The need to design and analyse such events comes in the wake of growing threats…to both naval and commercial vessels in the international waters."

Dytran has been designed to accurately simulate all such events; a feature that helps IRS engineers to simulate and analyse critical underwater explosions for gaining early design insights into the performance of ship structures.

The simulator will also help engineers to design ship structures that will be able to withstand large shock loads generated due to UNDEX.

IRS Research Division vice-president Dr A Samanta said that the society aims to act as a catalyst for the maritime industry to self-regulate and ensure safe ships.

"Dytran takes us one step closer to achieving this objective by allowing our engineers to virtually validate critical events such as underwater explosion," Samanta said.

"Use of simulation is helping us to achieve higher levels of quality and reliability, which is very crucial in this industry segment."
